Meantime, to get FlightGear LINKED, I downloaded, and installed the OpenAL (WIN32) SDK 1.1 binaries, and used those for the SimGear/FlightGear COMPILE and LINK ... This presented a small problem, in that, in this SDK, which will install in C:\Program Files\OpenAL 1.1 SDK\ by default, the 3 headers needed, al.h, alc.h, alut.h have been placed in an 'include' directory, whereas SimGear expects them to be in an 'AL' directory ... it uses #include AL/al.h and AL/alut.h ... Ok, so I created an AL directory, in the SDK folder, and copied them into there ... simple ... That nearly works ... unfortunately alut.h also includes al.h by just using #include al.h You could probably modify this to al.h, then MSVC would do a 'local' search ... al.h only searches 'include' directories ... This meant I had to provide BOTH 'additional include' folders, namely 'C:\Program Files\OpenAL 1.1 SDK' and 'C:\Program Files\OpenAL 1.1 SDK\AL' to the SimGear compile ... but, Bob's your uncle ...

Ok... I myself have been having problems with compiling FG with MSVC 7.1, but I've been told this much. Its way to hard to compile with MSVC6. But ofcourse, I submit to the judgement of the masters. They know way better. On 11/14/05, Sam Ingarfield - VK6HSI [EMAIL PROTECTED] wrote: Hi Any assistance would be gratefully accepted.

Re: [Flightgear-devel] openAL compilation problem
Add the libs to FG, SG does not need them. Harald. Hi Harald, Thank you for your reply. I did add the libraries to FG as you suggested but I still get the same errors. It looks like for some reason or the other the header files are not being read... for example the function alGetError is defined in al.h but even though the header file is included in soundmgr_openal.c the linker says that these are unresolved externals. Am I doing something wrong or is there something wrong with the version of openal I am using. I did download a copy of the openal windows sdk from the openal website. Thanks!! ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

[Flightgear-devel] openAL compilation problem
Hi, I'm trying to compile pre-rel-3 in MSVC 7 but i'm running into a linking problem again. It looks to me like simgear is unable to read the openAL header files while trying to link. I have put them in the sound_mngr directory and modified the include statements to read it directly from there, but with no luck. Am I doing something wrong? Thanks!

[Flightgear-devel] Jitter related
Hi all, I got two questions to ask... 1. When an aircraft has ZERO velocity, given some rudder input, and also when there is no wind, should the rudder actually have any effect at all? I see the c-172 actually turn, and over a period of time, if left alone, flip over, do some gymnastics, sometimes reset itself to some random altitude... Same applies to the elevator. I've noticed that it happens when jitter is more pronounced (with no wind), that if u pull back on the stick, the aircraft actually tries to pitch up. I don't know if this only on my version of FG9.8 (Windows)... 2. This would be more JSBsim related... I run FG on 2 computers on campus... the jitter in the cessna is more pronounced. I then ran FG with similar parameters (ie. no wind) on my personal laptop, again with Windows and with a similar configuration as one of the computers on campus. There was NO jitter!!! I have not edited any files, everything is being run as is after downloading the binaries. Is there an explanation for this behavior?

Re: [Flightgear-devel] Jitter related
This doesn't limit to the c-172. I do not know whether this has been fixed or not, but back in Feburary when I was testing the model for the A380, I notice that the wind is powerful enough to moved the A380 slowly from the center of the runway to the edge of the runway. Going back a bit further, when I was testing the model of the MD-11, a gust of wind could come and lifted the nose of the aircraft up. If the wind is strong enough, the aircraft would pivot all the way around its main landing gears, flipped, and sunk below the ground. Ampere I've seen what you talk about in all aircraft... except the point is that there is NO WIND!!! In my case, the wind direction is zero, the wind speed is zero, turbulence is zero, and I am not fetching real time data. Unless there is some code written in somewhere where u are generating gusts of wind at random, I don't see how any of the above is possible. ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

I do think its a good idea to have that as data sent, especially for people who might be designing automatic flight controls with flight gear.

[Flightgear-devel] Debugging Throttle control in Native-ctrls
Hi all, I'm sending joystick input through Simulink in Matlab to Flightgear using the Native-ctrls structure. I am able to control everything pretty satisfactorily, everything except the throttle... its gone digital on me!!! It fluctuates between a one and a zero in almost a random manner when I vary the slider on the joystick. I know I've setup the input data right... its scaled between one and zero. I know I'm sending the right data in the right slot since the throttle varies only if I place that input data there and it doesn't vary anywhere else. I've used to a port sniffer to read the packets as they are sent, and even there it seems perfect. Is there anyway at all that I can fix this?

Re: [Flightgear-devel] Debugging Throttle control in Native-ctrls
Throttle should be no different from any other value. There is probalby internal code clamping this to the range of 0.0 - 1.0 so if your numbers are coming through garbage and random, you might see this effect. If it was me, I'd insert some debugging code in src/Networks/native_ctrls.cxx where the incoming throttle data is processed to see exactly what is coming in. Perhaps something isn't getting byte swapped correctly or you are off by a byte or two in alignment? The data isn't random or garbage it is between the range of 0 and 1 before I send it to flightgear. The data that comes to flightgear is in 64bit IEE floating point format and I have been able to verify that with a port sniffer. I'll try and have a ago at your suggestions and see what comes up.
