Re: [Flightgear-devel] Heads up: AI/ATC interactions
Unfortunately introducing real world AI is not only awkward from the maintainability with different sources point of view. Its best kept as separate from FG as possible in my view. It clashes with scheduled AI aircraft, in that they can appear twice and cant do as good a job in the sim environment as the existing scheduled AI, in that the updates are to slow and must be interpolated to generate a smooth stream, and more so the coverage is not complete. Here the ADSB is 50 feet up the mast and only 7KM from the airport but still only gets reliable signal for aircraft at about 100 feet above the runway. The AIS receiver has the same problem in that when following the main route through the straits here ships are lost for a while when passing behind an island. I share my AIS and ADSB data with aishub and adsbhub and in return receive all data they collect, I see the same problems in EU data, EHAM for instance is the same as here in Bali, aeroplanes drop off the stream once they are on final into Schipol and just appear shortly after take off. I did see a project using aishub data to feed one of the MSFS variants, so i guess they would allow us to use it in the same way. I know as long as I feed my of air stream I am free to do what ever i want with the data aishub send me. In short it sounds great but it gets rather messy and complex very quickly. And there can be a lot of data to sort and filter out only what raw data is needing to be processed before display. Previously Durk mentioned in a post (18 months ago maybe) his thoughts of running the AI as a separate process, from this I had a tinker with the multiplayer code. In my case the master machine does not generate the window views. I found by adding a routine to echo the data received from the MP server to the slaves, It worked fine, one data stream to the MP server, only one instance on the MP server from me, and MP aircraft all appeared on the slaves. Recently I decided to go further with the ADSB data based on the MP server code by Oliver to do the job but have put it aside as it compiles on my old Suse 11.1 machine but not the new Ubuntu 10.4 installations. A picky new complier i think but I don't understand it well enough to sort it out. Now I am not a programmer of any kind and thus really cant assist those who are, I cant offer comment on HLA and how to implement things, I would only put forward that if the AI is merely socketed to slave machines, those who want to do more, can do their own thing with an external process using the socket IO. Or preferably work in together and produce a FG util to do the job. The external process would be the place to sift the combined data, then apply HLA or similar to generate just those targets required to feed to FG. I think, from the FG coding perspective, no more than options along the lines of generate AI to socket only, generate and display AI and display external AI from socket, is more than adequate for multi pc display setups and feeding in external sources without any hacking. I don't know enough about the options but would the existing multiplayer format be the one to use?

As mentioned above, feeding aircraft, ships, railways and whatever else from various sources will render the system unmaintainable (at least in the long run) if clear abstraction layers are not being considered and it also won't facilitate the task of interfacing FlightGear to other sim networks in the future. I've been mentioning HLA because it's the tool precisely made for this sort of interfacing complex simulation setups together. It provides nifty features like, just one prominent example, time-stamping (or time management in general): Pre-calculate the route of an aircraft carrier, feed it to multiple sims in advance and the ship will show up on every of the participating machines exactly at the desired position exactly in the desired moment. This is not a feature to be hacked into FG as an add-on, no, HLA is bringing this to you at no additional cost. Think of the same for AI aircraft or cloud positions.

Re: [Flightgear-devel] Understanding the design of aircraft nasal scripts
Catherine, Not quite the answer you seek, but following to Sids comments. My advice is keep any thing you want generic to your setup away from aircraft model nasal if possible. If it helps, I used xml for controlling some auto pilot functions via Joy stick control to avoid fooling around in nasal. I have attached the xml file for you as info. Some notes that should be in the file: The file is based on commands given to execute button presses in the 737 autopilot panel xml file. The trigger on button 0 is used as a shift function so the top hat left to right moves the heading, then shifted moves the course. Likewise un-shifted one of the buttons selects heading mode and shifted selects vor mode. I ran it inconjuction with the older 2d AP panel in the 2005 era 737-300 model, I am not sure about the new 3d panels. However its not panel dependent, it drives the autopilot setting and lock properties directly. and runs ok againt the current v4.5 737 series autopilot xml implementation or the basic generic FG autopilot on the current FG git version. I think it would run ok against any model, but would not promise it as i only use the 737 implementations. As far as I recall there are no funnies in it unique to my sim setup.

The autopilot xml file does the real work , but enabling a mode can be set with pretty much any property or condition the author decides on ,so that could be a large chore.Most extra nasal code was written for a reason , mainly to make the autopilot behave like the real one , so modifying that might be tricky.Just my thoughts, if you,ve already discovered all that , i apologize for the noise.

I've been able to get this to work on the Seneca II with a short nasal script in Nasal/SenecaII.nasal that sets the /autopilot/CENTURYIII/controls and /autopilot/CENTURYIII/locks properties appropriately. Silly me, I though it would be a simple matter to port the working code over to the Comanche PA-24-250 (w/ CIII autopilot). Unfortunately, the structure of the nasal scripts of the PA24 bears very little resemblance to that of the Seneca II. Although the relevant autopilot properties are the same for both planes, the flow of control is not. For example, turning on the autopilot roll axis control with the plane on the ground is harmless in the Seneca, but will cause a nasal crash in the (stock, unmodified) Comanche, and turning the autopilot off again will not recover. (The ailerons will be locked permanently at 0 until you restart.) The routine that crashes is action-sim.nas, a file that doesn't even exist in the Seneca. It contains an update_actions() script that is looped repeatedly, updating positions of control surfaces, etc. With the autopilot on, the script attempts to get the appropriate aileron position from the autopilot, but it returns null and then cause a setValue() error when it blindly tries to set the actual aileron position to that null. The same thing happens if I turn on the autopilot in flight by using the joystick to change the /autopilot/CENTURYIII/controls properties through a script. Is there a general file and scripting structure that it is recommended to follow for implementing aircraft? It's very challenging to learn to understand and modify aircraft implementations when the general arrangement of files is so different from one to the next. -- Xperia(TM) PLAY It's a major breakthrough.

Re: [Flightgear-devel] jbsim nose wheel steering control, 737 models
Thanks Eric, I shall play with this later tonight. So just to clarify my understanding, on the 737NG600 model I would add this code to the fdm config? That being the aircrafts 738.xml file rather than the 736-set file. I assume this means the gear/gear-cmd-norm property will be writable and the rudder values will be ignored. I expect i will have to do a bit of coding to get it all nice but thats ok as long as have control of the properties. On a sepaarte topic, but you recall my questions about sound and slaves? Since then I have added a couple of extra menus to the gui sound (and properties) for two slaves, Then added them to the gui network io stream, now I can run the nav effects, on the slave machines totally under control from the master. Thus bring the sound chips on the slave PC to use. I will put it up on my FG webpage with other multi machine FG setup notes i have made.shortly, as its really only of interest to sim builders I guess.

[Flightgear-devel] no engine fuel flow in 737-600 but ok on 737-300 how is it defined?
I have been making some panels and lots of tinkering etc for a 737-NG600 based set up, upgrading from the old 737-300 based model i have used in the past. The 300 model used *fuel-flow_pph* from the engine prop tree to drive the panel fuel flow meters. In the 600 model these values remain unset, but the engines are the same, and the model engine configs for the CFM56 are identical files and don't define a fuel flow rate. I see these days there is a nasal script that adds *fuel-consumed-lbs* and * out-of-fuel* to the engine properties, but it also relies on the flow rates so the total and flag are never set. It must be in the aircraft model somewhere as one works and one does not, but I cant find it it anywhere in the old 737-300 model. On top of that I see the fuel levels on the tanks is dropping when the engines run. Even then the tank valves are turned off. And the engines only start when there fuel in the tank then stop as soon as the tank is empty. So can anyone advise what is the story here and how the *fuel-flow_pph *is defined? I assumed it was just a function on the engine in jbsim I need bit of a primer here. -- Regards Harry -- Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

HI Torsten
Thanks for the reply,
Are you sure about this? I believe my distro 737-300 model is is up to date,
and almost identical to my 2008 one, but either way I dont have any file
Nasal/system.nas in the 737-300 directories and it gives a pph value on the
engine prop tree though no gph when running. The model is almost a pre nasal
design.
The 737NG600 has both gph and pph but neither has a value on its prop tree
when running.
Also, the way I read your snippet, this nasal code requires a *fuel-flow-gph
* value then calcs *fuel-flow-pph *but my props for the engine dont have a
value in either.*
*Now I am really confused.*

There is Nasal/system.nas in the 737-300 directory. Around line 200 of that
file the code
pph1=getprop(/engines/engine[0]/fuel-flow-gph);
if(pph1 == nil){pph1 = 0.0};
pph2=getprop(/engines/engine[1]/fuel-flow-gph);
if(pph2 == nil){pph2 = 0.0};
setprop(engines/engine[0]/fuel-flow_pph,pph1* fuel_density);
setprop(engines/engine[1]/fuel-flow_pph,pph2* fuel_density);
computes fuel-flow_pph.

Well I have had a poke around (blind man in the dark scenario) in the jbsim turbine code and found the fuel flow value is already and always generated on a per second scale, And also Oil Temp ,another goodie i was looking for, from there is appears on the *fdm/jsbsim/propulsion/engine* property tree. I am not sure how it gets over to the engines prop tree and multiplied to hours in the model but I will take it from the fdm for now. And it looks like JBSim is taking the fuel from the tanks as well. I have to much to learn here.

Re: [Flightgear-devel] Real-time shipping traffic
Ok Stuart Sounds good, Ok on the ferries, nothing around can be said to move on water at high speed. I had not seen AIShub before so I had look, I see allow you to nominate an area for data sent from their server. They provide a binary send your off air data to direct to them, and allow their windows app to view it back from a port on their server. Thus to do much with it outside of that, you are back to rolling your own code. I did play around with the AI a while ago, but my butchered code would be way behind the development now. Firstly i was trying to get the AI and MP in sync over multiple machines doing the graphics. After that figure out how to put in the AIS ships and ADS-B aircraft. For MP I had one FG machine connect to the server, then echo the received server data stream to the 3 others to prevent 4 instances appearing on the MP server. That seemed to work ok. For AI aircraft, I exported the properties for all instances in one machine to the slaves so the AI planes appeared correctly in all windows. It was very messy, but worked ok till you went to Schipol and 100 plus AI aircraft started to slow things down. However at the time I think it might have been Durk said there might be a possibility of moving the AI into a separate sub-sytem in future. I need to go back and look at the current FG AI code. Its probably all different now. I thought a special version of the MP server might be the solution. but it became very complicated, and I am no programmer either. It seemed at the time, the FG AI had the capability to interpolate and predict the movements. With aircraft its bit easier because the ADS-B updates once a second, the AIS ships can be a couple of minutes apart. Probably the cause of your issue with the fast ferries. The other option was make a torn down core version of FG, just running the AI, and seeding it with AIS and ADS-B real time data. It would also handle MP data, Thus if the AI system generated a scheduled aircraft flight, and the real one appears on ADS-B, use the real data. This would all be supported with the live off air audio from a couple of receivers. All in al a nice realtime sim environment. Which ever way, It seemed the best thing was to run it all on a separate machine and just seed the FG machines with the AI marine and airborne items in total. If I just use my local AIS and ADS-B realtime data its not to much, but if you say 7000 ships, and i guess similar numbers of real aircraft in the air there is potentially a huge amount of processing involved. Normally at any given time here in Bali there no more than about 6 ships and 15 aircraft in range of my receivers. Like the marine AIS there are sites with Aircraft ADS-B data showing live traffic. I have also seen mention of live ATC comms being available as audio streams for some areas as well. There also an ADS-B data sharing site like the AIShub one you mentioned. http://www.adsbhub.net Like the AIS hub they allow you free use with their data as long as you have a receiver feeding to them. Some of the libraries here for sharing aircraft tracking data might also be of use for marine AIS data, but I have not checked them out as yet myself. http://www.libhomeradar.org/functions/index.html Harry On Fri, Mar 4, 2011 at 4:13 AM, Stuart Buchanan stuar...@gmail.com wrote: On Thu, Mar 3, 2011 at 8:45 AM, Harry Campigli wrote: Hello Stuart, Have you gone any further with your AIS scripting?

As you may be aware, AIS Hub (http://www.aishub.net/) allows people running an AIS receiver contribute, and more importantly receive, raw NMEA data. If you have an AIS receiver, you should be able to join the group, and receive worldwide data (well, where there is coverage). AFAICT there is no restriction on usage. With a feed of raw NMEA data, it should be fairly straightforward to modify the MP server to act as a proxy and push shipping information into the MP data

The data is transmitted by radio and includes position, speed, course, rate of turn, as well as the vessel type, dimensions etcs.. The project collects the data from various volunteer receivers and collates it into a DB, and provides mash-ups over Google maps etc. I think there could be a very nice little project to incorporate a data feed from their server through a proxy and into our MP network, displaying marine traffic in real-time. This would completely obviate the need for AI shipping routes, and at a stroke, the sea in FG would become accurately populated. Having a bit of spare time over the weekend, I put together a pretty simple perl script to act as a proxy between the marinetraffic website and FlightGear. At a high level the proxy works as follows: 0) FG is pre-provisioned with 40 AI ships at start of day 1) The script gets the current aircraft position from the property system over the telnet interface 2) The script make an HTTP request to marinetraffic.com to get all the ships within a 1 degree x 1 degree square centred on the aircraft position. 3) For each of the ships, the script sets the type, position, speed and heading of an AI ship with the data using the telnet interface again. The resulting screenshot isn't particularly impressive, but it does look more realistic than the distribution and heading of the normal materials.xml random ships: http://www.nanjika.co.uk/flightgear/ships.jpg The screenshot shows a couple of container ships (one with a tug at the front which has the wrong model) making their way up the Firth of Forth near Edinburgh. In the distance you can just make out a ship berthed at Grangemouth. There are a couple of limitations with this approach - We have to pre-define the number of AI ships in an AI scenario. I've got 40 on my system, but I don't have a good feel for what the overhead of each AI ship is. If the script finds more than 40 ships when searching, it reduces the search area and tries again. It would be much easier if we could define AI objects at runtime. - The telnet interface is very slow. It takes a couple of minutes to read and write the various properties. - The current proxy causes a per-client load on the marinetraffic website. I've emailed for permission to use the data feed, but I doubt they'll be too happy if we were to integrate this into FG itself and have a couple thousand clients requesting data every couple of minutes. I think some approach which uses the raw NMEA data to get and then feeds it into the MP network would be better. Unfortunately its not clear how we can do that. - Close to shore, ships seem to change their course such that a snapshot of position, speed and heading every couple of minutes is insufficient so we get jumps with each update. I think a better model might be to use the data as a sequence of waypoints, but I haven't investigated to see how easy that would be to implement. I've emailed the marinetraffic website for permission to use the XML feeds that I've reverse engineered and to see if they are interested in helping us with some raw data. Once I've permission I'll put together a package with the proxy and the various other changes so people can have a play. That looks like very good work so far. Let's hope you can make more progress.

[Flightgear-devel] Flightgear timing over network
I am looking to time sync 3 machines running FG over the network and would like to sync the sim times to one master machine. I have them all on nfs but it seems thats not quite the trick. So what ever time the master is working on, be it from command at start, or selecting for example noon on the gui menu, the others follow. I see in sim timing properties there are lots of values in the property tree, And I see system timing also comes via sim gear. Do is anyone familiar with the code know which is the root time source on the property tree? The one I can forward to the slave machines.

Re: [Flightgear-devel] Flightgear timing over network
OK thanks for the replies gents. I am sorry I made a typo in my first post, that being nfs instead of ntp, bit of a bum steer. However i have since found one machine did not have the daemon up. But more importantly thanks to Torsten's remark about /sim/time/cur-time-override, I had a dig around the code and found it is utised by the native-gui IO routine, and further to that its does time changes from the master to the slaves. So hopefully thats the end of it. Another little item to put on my networking Flightgear machines web pages.

It will also take care of any lags when your machines boot asynchronously or you need to reboot an individual machine. John Coming from the unix perspective, xntp is a pretty good tool for maintaining a very accurate real time clock setting on your PC. If you run this on all your machines they're real time clock should be *very* close to in sync. Then things like --timeofday=noon should work well.

Originally it was an UAV project using FG as the test aircraft, but there is no where in Bali to test fly, I meant moving back to Australia for open spaces, but the red tape there is murder unless you bush. However we both come back to the point of loading the property tree from our hardware, the difference being you are independent of Nasal. Problem for me is a lot of the refinements in the new models coming out do use it, This means I better have closer look at what the nasal is actually doing. I am sure my io routine could do a lot of it. But feeling well bitten here right now.

Fred, Csaba Thank you both very much for the assitance. First I installed gettext, it still failed to compile, then I added --with-fltk=/usr/lib to my configure line and it built with just one warning. that being for info : g++ -DHAVE_CONFIG_H -I. -I/usr/lib/include -I/include/ -DLOCALEDIR=\/share/locale\ -g -O2 -MT wizard_funcs.o -MD -MP -MF .deps/wizard_funcs.Tpo -c -o wizard_funcs.o wizard_funcs.cxx wizard_funcs.cxx: In member function ‘void Wizard::preview_aircraft()’: so I removed the gettext made clean and tied again and all was still ok. thus I have installed fluid (maybe already in most desktop installs) ./autogen.sh ./configure --prefix=$prefix CPPFLAGS=-I$prefix/include/ LDFLAGS=-L$prefix/lib -L$prefix/lib64 --with-fltk=/usr/lib make and it built ok. Again the same warning, but I assume its not serous? Providing it proves to be repeatable I will be happy, but I am installing it in a very minimalistic system running on stick. Many folks using normal desktop installs might not find the problems I do. Fred based on your previous response to my question about grabbing the output to FG, I have made a script to catch the output and filter it, then fire it off to multiple machines. Ie a master machine and 2 running as slaves for window views I have put it up on a new page, actually complete new FG based sub-domain on my site, http://flightgear.bali-gold.com/ Here i am putting my notes for FG in hardware sim settups with multiple machines, and bare bones hard-disk free installs. Not really of interest to the average desktop user. I have put the script with some notes at http://flightgear.bali-gold.com/howto_fgrun_multi.html Finally could I ask do you know where i can disable the call in FGrun to open the monitor window or pipe it to a file?

Re: [Flightgear-devel] Default Aircraft Candiates
Two things cross my mind, whilst I know the designers strive to model the true aerodynamics in the fdm. 1- how many fly these sims on realistic hardware? Would many even go as far as a set of imitation yoke and pedals? 2- I have spent some time in F28s set up for airport navaid calibration surveys in the past, No pax and no bags or cargo, not a lot of fuel onboard, and I have to tell you that aeroplane could really go!, those pilots could and would throw that thing all over the sky. There was never any hint of that performance riding in an F28 on normal passenger service. I suspect most people would run FG airliners without full weight and slack tanks which vastly alters the power to weight ratio of the aircraft.

Re: [Flightgear-devel] Default Aircraft Candiates
Memories, heres an old article on we we were doing in the F28s and airfield surveys, whilst off topic, it may be of interest. http://www.airwaysmuseum.com/Flying%20Unit%20navaid%20cal%20article%201990.htm Item 8 -- (8) good low speed handling and go-around performance from very low altitude; This i clearly remember like yesterday, sitting in the jump seat at the end of a VASI approach test, under full power doing 180 turnback to 1000 feet, cows beside the airstrip just below us, running in all directions with their tails wrapped up over their backs. It looked like we were going to put the wingtip up their backsides. We thought it was a hell of a joke, but the farmer I assume was not impressed.

Re: [Flightgear-devel] ..pulseaudio fix in ubuntu,
Thanks Eric, With out yet looking in depth at how the sound is done in SG and FG, I guess this means its a similar task using PA or putting in another couple of sound cards as far as what I need to modify. More cards would avoid the PA overhead on the processor already mentioned.

Re: [Flightgear-devel] sound via simgear
Hi Eric, Thanks for that, I would be most gratefull to lias with you on FG sound To explain its a multi motherboard sim setup with Boeing panels interfaced via a can network. Each nav, comm and dme head has its own volume, these I expect can be dealt with, what i was hoping to do was use the audio in a mono format, like steer nav and com audio to the left channel feeding a head set, and them maybe alarm audio to a speaker via the right channel. Which ever is controlled by the pilots audio panel interfaced to the system. This would be aside from the normal sound effects running on the main sound channel. Be it achieved by adding in additional sound cards in the main machine, or utilizing the sound chips on the networked machines that run screens (which would require some additional on the network io). But I know my Intel 945 series motherboards have sound chips with front and back connections, but i dont know if the chips will support different streams for each one, as far as i recall they only report one audio device and no inbuilt mixing. Maybe a better sound card with hardware mixing is required. From what you say, adding extra sound cards would require modifications, I guess to sim gear? Would this be along the lines of cloning some modules and defining them to each system audio device or more involved than that? Is Plib involved here as well? Also at some stage I have to work to get FGcom, and my local off air audio feeds into the system. Yes I will dig in with it further, and am just looking at possible ways to do it. Also keeping things to a minimum just with Alsa. I installed pulse audio (for the mixer) last night and it fouled up the system. I have minimal Ubuntu 10:10 with no gui on these machines, just X11, Alsa and FG.

I'm, not sure I completely understand what you're trying to do. The SoundManager in SimGear has a software volume control for all Sources, SoundGroups and for the SoundManager. At the moment it's not yet possible to drive multiple hardware devices but there has been a request before to be able to output the communication devices to a different audio jack than the rest of the sound effects.

Controlling separate channels could be a problem although there may be a way around it; placing one source to the right of the listener and one source to the left, both streaming the appropriate channels.

Re: [Flightgear-devel] Cmake + VC2010 link errors
Allan I know nothing about building on windows, but I have found installing osg multiple times on linux can cause issues as it does not always un-install cleanly, and the next install may not overwrite what is left behind. All is nice till you try and compile against it. Especially if its a different version. It had it leave sym links and stuff behind, which fouls thing up when you install a different version. Just check you have not got anything left from previous installs. Maybe you need to remove osg and make sure its clean then reinstall it. I guess it has a log of there it puts things?

Re: [Flightgear-devel] sound via simgear
Gee Arnt, i am not the one to say, for starters what I am doing is quite off track compared to the average flight gear user. I have to remain prepared to hand do things to suit my needs. If I can hand edit a file in /etc once and know its going to stay that way I am happy for my setup. I am not running gui's either. In my short time over on Debian, or really Ubuntu I got the impression from reading that they had gone pretty much all in with Pulse Audio. I was rather surprised to find the text only server install had Alsa on it by default. Also I think I saw mention Suse had gone with pulse as well, but I might be wrong with that one too. But if pulse is becoming mainstream in desktop distros it would be good if it handled multiple cards and did all the hard work, as long as it does the job with out creating more issues. Depends on where the developers are heading with FG and if you can get Pulse or Pd on the job. That puredata looks pretty swish! I downloaded their Ubuntu 10.10 deb file, so I will see what it does tomorrow. All I know is the nearest thing to good audio on an aeroplane is the passenger entertainment system, not the am comm radios. Cheers!

Each nav, comm and dme head has its own volume, these I expect can be dealt with, what i was hoping to do was use the audio in a mono format, like steer nav and com audio to the left channel feeding a head set, and them maybe alarm audio to a speaker via the right channel. Which ever is controlled by the pilots audio panel interfaced to the system. Controlling separate channels could be a problem although there may be a way around it; placing one source to the right of the listener and one source to the left, both streaming the appropriate channels. OK That could be an option to explore, probably only need to relocate the source via the property tree when an device is switched to head set. But I know my Intel 945 series motherboards have sound chips with front and back connections, but i dont know if the chips will support different streams for each one, as far as i recall they only report one audio device and no inbuilt mixing. Maybe a better sound card with hardware mixing is required. To my experience it's almost always possible to distinguish between output jacks so that might not be a problem. OK best to forget that approach then. ..why? If it works ok the way we want it to, we can use it. From what you say, adding extra sound cards would require modifications, I guess to sim gear? Would this be along the lines of cloning some modules and defining them to each system audio device or more involved than that? Is Plib involved here as well? It would require modifications to both FlightGear and SimGear, PLib is not used for sound. Might have to study up on that side of things then. But as i already have an additional network driver running, maybe i should look at what need to be added to it and have the slave machines generate nav audio, may be atc chatter. Also at some stage I have to work to get FGcom, and my local off air audio feeds into the system. Yes I will dig in with it further, and am just looking at possible ways to do it. Also keeping things to a minimum just with Alsa. Actually we're using OpenAL but it can be set to use ALSA as a backend. Ok, I am reinstalling a machine right now, If i only have OpenAL, I can remove any alsa presence, would that mean the only audio control would be via FG, I needed to use Alsa mixer from command line to bring up the level on the front speaker channel go get sound out of the machine before. I installed pulse audio (for the mixer) last night and it fouled up the system. I have minimal Ubuntu 10:10 with no gui on these machines, just X11, Alsa and FG. I've given up on pulse audio and would not encourage anyone to use it in a serious simulation environment. well count one bad experience with it here, last night!! ..hum, a minor annoyance on my laptop, is having to do a daily alsa force-reload and then reset pulseaudio. Work ok with FG, and I understood it could handle multiple sound cards? ..how about puredata? http://puredata.info/ , is realtime and can do graphics too, given plug-ins. ..I've seen _lots_ of Pd plug
Re: [Flightgear-devel] ..pulseaudio fix in ubuntu, was: sound via simgear
Interesting amongst the comments on that page, You can net-stream to your LAN through PA as well. Just run the PA daemon in all your running boxes and each one of them can become a sink and a source for the others. That might have potential in a set up with mutiple machines networked in a FG setup in the future? Nav and com to separate motherboard sound chips otherwise not being utilised.

Hey Thank you Frederic, I get the gist of your message, I point fgrun at a script that will accept the argument string, sort out the options then fire of relevant the command to the various machines. i am all for having a custom script to deal with these unorthodox setups than needlessly tinker with code I don't fully understand.

Would I need to fake fgfs back to fgrun with this script? Or just let the script do its thing and exit normally once its kicked off the various machines. Fgrun then just thinks fgfs terminated normally, albeit rather quick?

Re: [Flightgear-devel] io configs
Hi Curt, Thanks for that, being one to give it a go, this arvo I put wrote a small generic shell script that starts up fg on each machine. It just reads 2 files of a server, one unique for that machine, the other for all machines. Its build the fgfs command line then issues it. I figured the FG IO streams were built via simgear right at init rather than later on the property tree. For info I have the machines all running TWM under ubuntu on thumb sticks. So each install is identical with configs and scenery by nfs from the server, next step is to move them into a a ram file system image which loads and boots from the stick or pxe. Although not Flightgear, you don't remember how you set up the auto logon, thats rather looked down on in unix circles and I have not found any answers to that question around the net.

[Flightgear-devel] current git FG OSG bulds on latest debian lenny
Could I ask how the latest git repositories fall in. For info: I have just installed via network the latest version of Debian Lenny (so I can buld FG debian liveboot images) after many years of building FG on Suse distros. I found a few Debian funnies (to me), a complete new arrangment of X for one, but understand different distros sometimes do things differenty and I am feeling my way. But i think the nvidia driver is ok (module loaded and good video) but glx info is not availible? Also some oddies with unavailible dependancies for OSG. cairo, poppler-glib, librsvg-, gtk+_2.0 and Gtkglext-x11-1.0, it seemd to compile an install ok and osgview is functional. I am not sure if these missing items will effect FG. I followed a rather good Debian FG install page from the wiki which listed the OSG dependacies, ( I assume as far as FG is concerned) they all were downloadable and installed ok. So first build of SG and FG went OK, but FG had a seg fault when it fired off the second thread, splash screen progress setting up time and render. from gdb I figured OSG problem. So grabed the very latest OSG. 2.9.11 i think, however SG compile drops on another OSG issue. So for now I have been back to the nvidia setup and rebuilding OSG. I might have more os dependacie issues to sort, this is not the place to enquire about them unless somewone has just setup a new Debian net install. I have problems but i dont think they are actually FG related. I need to follow them up on other forums. What I would like to confirm is, are there any issues with the lastest git OSG with respect to the latest SG/FG git sources? Also if anyone has dealt with this latest Debian lenny from a FG point of veiw.. If so what is the best version of OSG to install as I have seen numous posts here and on forums pertaining to changes of OSG of late?.

Re: [Flightgear-devel] current git FG OSG bulds on latest debian lenny
Hello again Arnt, As you would have guessed I am working my way towards debian live as per your advice previously. For now I am leaning my way around Debians way of doing things. Rather pleased as I have just compiled todays SVS against OSG 2.8.8.3 (as advised by Thorsten) on Lenny and it appears to run quite nicely. It was however a long haul, quite a few apps from backports and where ever else along the way. I had not been near a kernel rebuild since I put a soundblaster card to RedHat3. A lot of mucking around to get the nvidia module loaded and driver running, a new learning curve along the way. But that gives me some debian grounding before I start to build my image files This box will take over all of the server duties from the suse box and be a platform for building my live boot images. My FG machines are all the same Nvida card and Intel mother boards to this one. To be honest I installed mesa but not sure if was the correct one, so many apt-gets and dpkg commands in one day! I will let it run the updates to sid over night and see what happens in the morning. No big issue to wipe the system and start again with a minimal text system and upgrade to twm and an xserver from from there, if teh upgrade is not sucessfull because of something I have installed.

But i think the nvidia driver is ok (module loaded and good video) but glx info is not availible? ..you have mesa-utils? (Is that the right one for nvidea users?) ..another reason for Debian Sid, or Debian Squeeze, they add the nouveau X driver that the nvidea owners can use to verify Nvidea is doing the right things in X, FG, etc, X.org's nv can only do software rendering. Also some oddies with unavailible dependancies for OSG. cairo, poppler-glib, librsvg-, gtk+_2.0 and Gtkglext-x11-1.0, it seemd to compile an install ok and osgview is functional. I am not sure if these missing items will effect FG. I followed a rather good Debian FG install page from the wiki which listed the OSG dependacies, ( I assume as far as FG is concerned) they all were downloadable and installed ok. So first build of SG and FG went OK, but FG had a seg fault when it fired off the second thread, splash screen progress setting up time and render. from gdb I figured OSG problem. So grabed the very latest OSG. 2.9.11 i think, however SG compile drops on another OSG issue. So for now I have been back to the nvidia setup and rebuilding OSG. I might have more os dependacie issues to sort, this is not the place to enquire about them unless somewone has just setup a new Debian net install. ..an easier way to find out is make an usb-image we can put on keys and try boot, nearly all machines that can run FG, can also boot off usb, and you probably don't wanna do a nvidea-only FG net booter.

[Flightgear-devel] FG in ramdisk from a net boot
Hello folks, Could I ask if any one has had FG or for that matter any app on a linux box running in a ramdisk environment with no Hd? Why, its fast to boot, fast to run, and means no harddisks, everything is preconfigured on boot, rather good for FG systems with multiple networked linux boxes especialy if motion is involved as HDs dont like it very much. What I am trying to achieve is a net boot from a server from the MB bios resulting in a minimal but normal working linux system (in my case suse11.3) in ram. To explain a bit, I use this method for system installs, and its dead simple and fast, the server runs DHCPD, TFTP, and NFS, and has the install media (files from DVD) in a directory The empty box boots, gets an ip from dhcpd, gets the kernel and initrd from PXE/TFTP, the installs via NFS. No floppies DVDS or sticks and its much faster than using a dvd let alone the time to burn one. Basicaly I need to do is make a special initrd to build a ramdisk, populate its file system with the required files to support the video and MB hardware, FG and TWM. The FG start script gets (copies in) the config files specific to that box via NFS. This type of approach is common in the embeded linux world, but so far I have not found a project embeding a normal linux distribution into a normal MB ramdisk but there must be one on the internet somewhere? Its not really an FG issue, however I only want to use the box for FG and supporting programs. and it could be of use to other FG users. Finally the question, has any one been this road before ? Any thoughts, advice, warnings, recomendations, pitfalls to avoid would be apreciated before I get to far down the road! -- Regards Harry Sanur, Bali -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

Re: [Flightgear-devel] FG in ramdisk from a net boot
Helllo Martin and Arnt, Thanks for the replies. I better explain myself and my reasoning a bit. I fully agree that you are quite correct in that the ram load up is quicker directly from the HD than over a network, but I am aiming to do away with Hds in the FG sim boxes. First, re my mention of speed, I am meaning the running of the whole os and FG entirely in ramdisk after boot, the pc being ramed up a bit more than normal to have room, so I mean fast in respect that after boot, the whole show is in ram. Secondly, I meant fast in the respect that a new system install is far quicker than from a dvd, especialy the hassle of burning them, and latter having problems with reading them. Sorry I was a bit off subject and unclear before. Thirdly I mean quicker than running the system on a thumbstick. For about a year I have had FG2 on suse11.2 running on a Kingston 8gb data traveler with no HD at all, its good, easy to install and runs ok, possibly bit slower to boot up, but its only a matter of time before the stick write will definetly wear out. I think its a reasonable quality thumbstick but may be wrong. I planed to use the stick as the basis to load a ram based install, so seeing it worked ok as the system drive and intending to work on the ram disk aspect, I brought 4 more of these same Kinsgton 8 gb sticks for the remaining pcs in my FG setup, only to find on delivery they looked a bit different, unfortunatly they were also somehow different inside and till now impossible to make bootable unlike every other stick I have tried. Thus I figured, better and cheaper to have everything come from one server sitting on terra firma, HDs are not a realistic option for me because of the motion. On the same score, as Arnt mentions,I guess SSDs would be the best way, and a lot easier to implement from this point, last I looked the prices were abit scary though? I will download a Debian live image, search out soem documentation and howtos for it and have a play. Without opening a can of worms about Os's , I have used suse since v5 or 6, but make no claim its better than any other, just the devil i am most familar with. Would Debian be better than Suse for this for any particular reason. Assuming both are recent releases. Arnt could you also breifly explain your mention of clustering in Debian live? I guess if possible I would like to stay with as close as possible to a normal upto date off the shelf linux release, one that can be installed in the normal HD, have everthing required installed complied, set up and configured , the finally sort of cloned off with minimal modification to a ramdisk. I thought a patched initrd would make this easy enough and keep hacks to a minimum? This means the OS can easily be updated with the development of FG. regards Harry On Mon, Jan 17, 2011 at 7:21 PM, Arnt Karlsen a...@c2i.net wrote: On Mon, 17 Jan 2011 09:46:04 + (UTC), Martin wrote in message ih134s$q03c$1...@osprey.mgras.de: Harry Campigli wrote: Could I ask if any one has had FG or for that matter any app on a linux box running in a ramdisk environment with no Hd?

Re: [Flightgear-devel] FG in ramdisk from a net boot
Thanks gents, Bearing in mind I only want these installations to run FG and supporting apps. I had a look at ssd prices today, maybe its time for a rethink. seems there a a lot of small 32g 2.5 sata ones for around the 70usd mark. Infact there are even cheaper ones but they seem to be a lot slower in access times. USB thumb sticks are not so much cheaper for similar sizes For that kind of money a small sata ssd is maybe a more sensible aproach than trying to load a ramdisk? Just normal distro sata install but all of hard disk issues are done away with. I am having a play with LTSP, and have downloaded Knoppix, and now am having a look at the re mastering information, it looks good. I will take some time to learn a bit and play with it. I did not consider live boot cds before, I did not see the potential in what I passed off as a demo gimmic. But it might be the way to go if used in a stick. I can use the PXE to work around these weird Kingston 8g sticks I have that wont boot.

[Flightgear-devel] building minimal fg for only for a slaved instrument panel
Hello all, I would like to set up a networked slave in the normal manner, however I only want it to display some instruments on a panel of my design in an osg view. For this I would like to use an Intel atom board which is a pretty feeble MB but suits because its small, and low power use. These boards don't seem to be up to running FG V2 in the normal mode. But surely this MB can generate and just display the instruments when the FDM is shutdown and the values are coming in on a socket. I realise I can deny the local scenery files and make a minimal aircraft model to cut down the work load, but i would like to ask Firstly has someone done this before? Secondly before I jump into the code again myself, is there an easy way or what might be the best place to stop the processes that try to tile the scenery and other processes I don't need? For starters I plan to drop of as many subsystems not required to just display the panel as i can from the subsystem init in fginit.cxx. and see what iI end up with. I would be interested in other folks thoughts.

Re: [Flightgear-devel] building minimal fg for only for a slaved instrument panel
Hi Anders, thanks for the response. Well I am a hardware man, absolutely no programmer, but I have managed some C in microchip pic for my sim hardware (mostly modified scraped avionics and panels) and written up a IO driver for it in FG, so for me, starting from scratch is not an option, I do know my way around FG a little bit now. I could work with making the Volkswagen from a Porce approach. I like to stay with the existing FG instruments and way of doing things. Also if possible I want to retain the sound hardware availability on the slave. So I am still back to a minimal FG compile solution. If need be I will just use a normal MB, its just these small Atom boards are ideal for the job from the point of cost, size and power usage. A cost effective solution especially when just run from a memory stick. I have found a few win add ons that just display instruments, but so far all are MSFS add ons, quite pricey and I am uncertain if there is enough detail freely available to write a driver or protocol to talk to them as they seem to hook into a windows dll. Also there may be some options in the Glass Cockpit project, I saw somewhere someone had revitalised it again. reg Harry On 5/18/10, Anders Gidenstam anders-...@gidenstam.org wrote: On Tue, 18 May 2010, Harry Campigli wrote: Hello all, I would like to set up a networked slave in the normal manner, however I only want it to display some instruments on a panel of my design in an osg view.

Hi, My suggestion is that you find or write an application that displays just instruments. You can easily get the relevant data needed to drive the display out of FG using the generic protocol system. That way you don't need to change FlightGear at all. I suspect that there might even be existing appropriate programs out there to just render instruments driven by data sent from FlightGear or some other flight simulator. Hmm, or was part of your requirements that the instrument (panel) is created in the same way is in FG (i.e. the XML and 3d model files)?

Re: [Flightgear-devel] Elevator control loading
Ok Wille and Allan For pix of works in progress, if you go to http://www.bali-gold.com/Avionics/index.php Then to the sim two directory, I have put in some new pix with comments on them of the rudder setup and the unit i am building up right now which will be for the ailerons. This design is based on a 737 feel unit but no hydraulics. Allan, I used bungee on the rudder pedals and gas struts on the toetip brakes in my first sim, they felt good but they dont last long here in Bali, I guess high temps and humidity is always 80 plus also they used quite some space under the cockpit. The only setup I have actually seen myself was magnetic braking on a Frasca 205 sim I looked after back in the early 80s, and they were to simulate hydraulic failures as I recall. I really think today the best way is a big servo motor and do it all in software, but I suspect 3 of them with the correct gearboxes and control electronics and then getting them to Bali would be way outside the budget. And as I said lots of folks on forums have tried different and expensive motor types and I have not seen anyone say this is the one, realistic feel and reliable Having said that its a few days work to prepare all of the bits of steel and assemble the ones I am making now, plus the cost of 5 bearings, 2 motors with controls and a bit of steel. HoweverI am pretty happy with the feel of the final result after a months work on the pedals.

Re: [Flightgear-devel] Time to help to develop a funtion to attach AI
Martin,
After spending the day in c++ help files and inserting printf all over the
place i have managed to follow it through and get the code up and running
for one aircraft Hopefuly tomorrow i can finalise it.
2 question for now,
Is FG running mutli thread thease days, ie do I need worry ablout clashes
betwwen an io cycle and the AI system with object?
I am not sure how the lists in the ai work but whats the difference between
_dt and dt? eg as in this line from AIManager.cxx
(*ai_list_itr)-update(_dt);

[Flightgear-devel] Time to help to develop a funtion to attach AI models in FG
Hi guys, I was wondering if i can find someone with a little time to help write a small funtion to attach remote Ai aircraft to the Ai subsystems. My problem is i just dont know enough about c++, I have tried for days to clone off and build a workable function but just end up at dead ends. Probably an experience eye would spot whats wrong. All of the Ai properties are availible on a new branch of the tree, having been copied across from the master FG machine, I just can't come up with a workable solution to prepare a new aircraft stucture, copy in the few required items and call the Ai attach function. I doubt its a big job for anyone who is familliar with the techniques involved. So if any kind soul has the time to help me work through it pls drop me a line -- Regards Harry harryc...@gmail.com -- Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.

Re: [Flightgear-devel] Help needed fo write an FG string property
HI Curtis thanks for the response,
Well I tore my hair out for a couple of days. But I could never make any
sense of the string stored in the structure, nor could I find a string
terminator in it. I dont know exactly why as i am not very experieced in c
strings.
I ended up putting the property to a local string, then writing it into a
normal char array in the structure adding a teminator after the last
printable.
Certianly not elegant but works for now to load the stucture. A programer
would write it differently to me!
tempnode = node-getChild(registration);
pt = net-registration[i];// pointer to array
in struct
pt[0] = '\0'; // put an end
of string for default
if ( tempnode != NULL ) {
temp = tempnode-getStringValue();
n=0;
x=0x31;
while ( (x 0x19) (x0x7f) (n SL_MAX_REGISTRATION)){
x=temp[n];// pointer
to prop string to send
pt[n] = x; // wite to
the struct string
n++;
}
pt[n] = '\0'; //0x0A;
}
From the structure Its written into the other machine with
node-setStringValue(registration, net-registration[i]);
The file is a clone of the native controls io, purpose being to forward the
clouds, AI and multiplayer info to the slave pcs for display.
Now I have the Ai aircraft data across to the slaves, my next question is
where does FG pick up the AI items attached for display by the AIbase? Ie I
need to fool the slaves to display the imported aircraft from the data,
preferably with out diabling the Ai base as It is still used displaying the
multiplayer on the slaves from another protocol and port.
I know i could do it with a cloned Ai update funtion, but maybe i can do it
at a lower level?
BTW ref our mail of last weekend, I have been putting a drawing together of
how I have interconnected the sim aircraft hardware by can bus to FG I
would have mailed it by now if I had not been banging my head on the walls
with this string issue. I will revert with it shortly

At a glance, this looks like it should work. I believe getStringValue()
returns a const char * type and you should be able to assign this to a
string variable like you show in your example code.
If I was going to dig into this, I might start inserting some printf()'s to
dump out the value of tempnode-getStringValue() to make sure that is sane.
Make sure [i] is a sane index value, etc. Off by one errors are pretty easy
to accidentally introduce. Hehe, I still have trouble with those off by an
order of magnitude errors ... :-)
Without seeing your surrounding code, I think I would be most interested in
first checking the value of i. That should remain between 0 and 24 (i=25
would be an array overrun because you'd be referencing the 26th element of
the array.)
Best regards,
Curt.

Re: [Flightgear-devel] control an aircraft from a file
John I am no expert but depending on what you what to do, one easy option is to use an existing io format. FG is rich in the interfacing department and the property tree arrangement makes hooking in most contols possible and easy. FG has an option to replay from file you could investigate, another is the generic io protocol. This is how i interfaced most of my hardware originally and you dont need to modify any FG code, just write an xml file. The flight gear io protocols all support a socket interface, I suggest you have a look in /src/network and you will find that sending control data into FG with a string is not difficult. Have a look at the Atlas.c as an example.

Re: [Flightgear-devel] Help: Building a binary IO driver based on Altas driver
Thanks for the reply Curt,
I took your comment onboard, Not much time today so I still have not
modified the process routine, but have instigated printf for testing. I wish
I knew it was so easy to so that earlier.My background in single chip
devices where there is no screen!.
Thus at the moment, the process routine calls the parse routine as in
yesterday, There I am picking up the number of chars in buf from
length. In the parse routine then I am testing each char and at the same
time sending the char to a printf.
If I test each char, from buf I can find 0x5a Z but not 0xA5. Futher the
terminal shows only the printable characters from buf. However it is a
steady cycle of the same pintable char data 10 times a sec with the non
printables missing.
From these 2 observations I suspect the non printables are not in the buf
array.
If I understand your response correctly, every time parse is called, buf
will hold fresh serial data and the number of bytes is in length, this may
not be the complete burst of data I send every tenth of a second to the
serial from my Pic. But if i gather these bytes and write them to an array
or file I will end up with a replica of the stream in. From that i could
find the sync bytes and recover the complete block of data.
However I realise once I have it working i need to refine the code a bit,
but if thats the case I seem to be missing the non printables.
You mention modifying the call to parse to call it only when its got the
full block of data. I would prefer very much not to be putting patches in
the other code outside of my sim file (cloned from the Altas one in
src/network), the only patch i have done is in fgio.c and that was to clone
the call for the atlas routine.
So questions
Firstly have i come to the correct conclusion above, and is it possible non
printables are not present in the buf data?
Could you tell me where in FG it calls the process routine for the various
io protocols? I seached today with out sucess, possibly from simgear?
Also the parse routine only seesm to run when i define serial in in the
comand line, where as I want the port bidirectional and would use bi in
the command line. eg, fgfs --sim=serial,in,10,/dev/ttyS0,38400 --httpd=5008
As i want to read in 8 bit hex data should i be looking at another method?
I apologize for dumb questions but I fully realize FG is quite a complex
piece of evolving code and I only want to hook in a small addon.

will only be read if they are available, and you can't depend on the entire
message string being there when you try to read it. If you back up to the
routine that actually reads the data in, you may need to do some work there
to accumulate the entire message before handing it off to your parsing
routine.
One thing I do quite often in these situations is to add printf()'s to the
code that reads the data in. Seeing the actual data values or message
lengths that are read each time can be quite instructive.
Best regards,
Curt.

Pics, pick up the char one at a time, check for the first A5, then 3 sync
chars from buf then if ok (synced up), copy the next 40 chars to msgin.
If thats ok then it sets a flag to decode the data. for now i also have an
0x0D on the end making it 41 chars. Later i intend to add the CRC routine.
Also I intend to use a network socket to the Pics once its all working. I
try to work in small steps.
It seems I cant pick up the first A5, as I understand it, buf has the data
in.
My question is how does the low level IO in Sg and FG work, am I wrong to
work on the premise that every time parse message is called buf contains
fresh data from the serial, Or does the the low level code require a CR? DO
i need to set up a static ring buffer os sorts and take the incoming from
that?
Below Is the code as it stands. i would expect to come out of this with
Msg_CS_OK=1, but maybe its not quite correct, for starters I need to pick up
the first sync char.

Re: [Flightgear-devel] Preferred development os
Hi Melchior, No its not political, and I am just looking for the best option for the future. I moved over to SUSE 6 early 90's from Redhat because Yast was really good and everything worked from the cds. Also the CDs were complete. These days it seems you need to buy a commercial version for the full house. That was in pre internet days as well. With 10.1 I did a bit of mucking about and got FG built ok, Same with 10.3. But now I seem to download lots if things, They have dropped a lot of apps off the DVD including FG, My net connection here in Bali is pretty slow (and expensive) , infact terminal compared to what I have experienced in Eu. So searching and downloading additional files is a drag. I can appreciate the legalities, but needing to download codecs just to get video and audio playing on 10.3 is a bit much. There are all these players installed but all need additional downloads, the messenger client did not work. The whole thing is just not like before. Vmware would not build either. As much as I would like it, I don't expect to just build FG or Terragear with out some work. I had a look at Fedora a year or two ago but felt SUSE was still the better option. My current sim setup is based on 4 SUSE 10.3 machines with FG v1.9.1, I have no complaint, but they are dedicated machines. I see Debian mentioned a fair bit. I install the basic Etch version and all the above basic programs are working full function from the DVD, even festival is installed. Vmware went in and ran straightaway. I follow the normal routine, some extras from the DVD and FG is built with no warnings or errors not much different to SUSE 10.3. Although I must admit with a new intermittant dropout in the audio with Al buffer messages on exit. So I was pretty impressed with the Debian, except I have never seen this AL issue before. I am not about to reinstall the 4 sim machines to Debian. I have not tried SUSE 11 although the dvds are availible locally. Believe it or not we have a specialist linux shop here in Bali! But I am preparing to try and make local scenery and airport layouts of WRRR the local airport here. Now i really need a Terragear system with all the additional tools. After failing with Terragear SUSE before, I am wondering if I am better to consider Debian for Terragear or possibly SUSE11, Maybe then I will find answers to upcoming problems searching lists and forums as other have already encountered the same issues with Debian. IE more people doing the same things with the same OS. Either way I expect to build up a directory of additional's locally to rebuild the machine.

I use OpenSuSE (11.0) without the least problems, and I wouldn't want to switch. m. -- Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.

Re: [Flightgear-devel] Preferred development os
Many thanks Melchior,Gerard,Martin and Jon, Please don't forget I am looking for the Terragear OS option that most developers are using. For the FG building side of things I see no reason to change the 4 FG sim machines away from SUSE 10.3 in the foreseeable future, Also after so many years with SUSE its the devil I know. But I guarantee you, from the Etch dvd, Debian plays mpg, avi, mp3 and flv, the messenger client works, festival is there and VMware installs either any issue. On SUSE 10.3 none of these work off the dvd, as they did with SUSE9. Well not on any of the 5 suse machines running here. Maybe V11 is an improvement and I need to try it next although I normally stay away from bleeding edge releases. The question is how is it with Terragear So till now for Terragear the only confirmed starter mentioned is Slackware 11.0,12.0 and 12.1 Harry On Tue, Feb 10, 2009 at 9:26 PM, Jon Stockill li...@stockill.net wrote: Harry Campigli wrote: I have used SUSE for years, currently using 10.3. but feel it has gone off since version 9. However I have always managed to build FG from source on it with a bit off mucking around but never Terragear. For along time I have wondered about Debian. I get the impression a lot of FG developers use it. Thus I have installed the etch verion. Everything from the install worked of the mark. Unlike SUSE. I managed to get FG installed with some small bug in the sound, and still fiddling about with terragear compiling. However its early days. Therefore could I float the question amongst FG developers as which OS is most commonly used or preferred as a Flightgear/Terragear development system. I use slackware linux for both flightgear and terragear. Slackware 11.0 has been my main development system for a very long time, and I had no problems. I've recently set up partitions with 12.0, 12.1 and 12.2 on for building packages, and encountered no problems with a flightgear build on those (the only change I needed was to use openal-soft rather than the old openal-0.0.8 code as 0.0.8 didn't seem to be liked by the new compiler). Building on slamd64 12.1 was also a pain free experience. Unfortunately building terragear on slackware 12.2 is something of a problem, since the compiler *really* doesn't like the newmat library, and there doesn't appear to be a newer version available - I suspect this will also be the case on other distros using the latest gcc.

Re: [Flightgear-devel] Preferred development os
Thanks for the reply Lee, Your comments all noted, especially with respect to stability, as opposed to bleeding edge. Thats fine with me as I have always been behind a release with Suse from 6 to 10 running machines as routers and servers over the last 10 years. Those machines only ever rebooted when the power outage outlasted the ups. I recall one uptime over 8 months. Something unheard of in the windows world I guess. And no problems with your comments the Flightgear again I build the requirements like Simgear and osg from source anyway, and could see no reason to update from SUSE 10.3 unless the Terramodel solution suited and one of them droped a drive. I was pretty happy the basics just ran on etch, although FG compiled with a small audio bug. I don't know much about Terragear because I have never succeeded in building it. But i gather the CVS is a mix of mainly old with some new. Are you running Terragear on your Debian machine? Regards Harry On Tue, Feb 10, 2009 at 10:40 PM, LeeE l...@spatial.plus.com wrote: Hello Harry, I've been a long-time user of Debian, in fact, it's the only distribution I've really used, so while I'm not qualified to comment on other distros I think I've learned some of the pros cons of using Debian. I would say that Debian's greatest plus feature is the stability and consistency of it's stable releases, and I would say that it's greatest negative feature is a consequence of it's greatest plus feature; it will always be using dated, or older versions of software. This is fine if the older versions of software that end up in the Debian stable distros are sufficient for your needs or you are developing your own software and don't need or wish to use 'bleeding-edge' versions of development libraries and packages etc. to make your software work. For something like FlightGear however, which largely requires the latest versions of quite a few other packages, it can be a problem. For example, if you wish to keep up to date with FG development and work with the cvs version of FG you won't be able to use the version of OSG in etch but will have to get a later version from the OSG project and install it yourself, which may in turn require later versions of other packages too. Now this may be ok if you don't use any other Debian packages that depend upon OSG but if you do you'll then hit dependency problems. There are ways around this but they'll require some degree, and sometimes a lot, of extra work and housekeeping to keep everything working. Incidentally, regarding OSG, I think the version that will end up in Lenny, which will soon become the next stable release (perhaps even this year - lol), will be OSG 2.4.0, which will still be too old for the current release version of FG. It also looks like the Debian version of FG that will be released with Lenny is 1.0.0. You could try using Debian's unstable distro but you need to be aware that it's a constantly moving target where dependencies are frequently broken. You really need a testing system if you're going to run unstable, to test updates before you roll them out to the machines you depend upon to work. You also really need to maintain your own partial mirror too, if you want to keep several systems in step because it's likely that there will have been further updates between the time you finish testing one set of updates and then start rolling them out to your other machines. Debian's testing distro varies a lot depending on the current point in the Debian release cycle. Around now, where Lenny has largely been frozen and where the current focus is on bug-squashing and final testing, it is very stable, but once it's actually been promoted and released as the new stable, testing will become very unstable and sometimes even less stable than unstable (speaking from experience) until it too is frozen. So perhaps for something like FG, Ubuntu might be a better bet, as it's based more on unstable than stable, with new versions of software being brought forward much more quickly than with Debian.
