Yes, the library (dietlibc) is compiled typing just make. The Makefile is not modified. I rebuild it with gcc 4.9.1. There are no other libraries involved. When using glibc I didn't made a static binary, and even so it was larger on Gentoo. Thanks Jorge

[gentoo-user] another headless device-question: In search of the LAN
Hi, For a device (beaglebone black) I am looking for a solution of the following problem: This little computer boots a fully blown Gentoo linux. It is used mostly as headless device (capturing data from attached sensors). From time to time I want access it via LAN. If the device was booted without LAN attached, the configured ethernet was not found and dhcpd fails. So Gentoo goes into no LAN-mode (or something like that). Is there a less waiting for the timeout-prone way to refresh the status of the LAN beside putting the accoring init-script into a cron job ??? Is there a way to check, whether a RJ45 was plugged into the device and if so to start init-script then? Thank you very much in advance for any help! Best regards, mcc

Then, on boot, set the date/time to what that file has, meaning it won't be perfectly accurate, but it will be considerably closer until ntp's available to it again. The most important thing that accomplishes for me is, while it doesn't keep the wall clock times accurate, maintaining the right order of times on log messages, etc. It also prevents a lot of issues with log and backup rotations that depend on 'which file is newer?', etc. -- Poison [BLX] Joshua M.

If you use openrc, you only need to install one of these programs,
not
configure or set it to run. OpenRC detects that one of these programs
is
available and uses it to do exactly what you need.

Unfortunately, ntp-client is configured via rc-update (added to
default) but after plugging in LAN the interface eth0 comes
up and I have access via ssh...but the date is set to the beginnig
of the UNIX epoch.
I have to call ntp-client by hand.
If you know that net.eth0 is specifically required to be up for
ntp-client to work, you should render OpenRC aware of the fact:

Using 'after' won't work unless both net.eth0 and ntp-client are in the

using ifplugd. Please try the solution mentioned in my previous post. It
should work.
On second thoughts, it might have the unintended affect of starting
net.eth0 before iplugd does. If you try it, let me know how it goes.

ifplugd shouldn't be in any runlevel, it is just there for openrc to use.
I suspect that the problem is that eth0 is up but inactive, so services
depending on it start but are unable to contact the network.

[gentoo-user] Headless question: Harvesting the results...software needed.
Hi, with lot of help of this forum (***TAHNKS!***) I now have a embedded device which is able to dis/connect itsself from/to the LAN, set the clock via ntp-client and is able to fire up a tool, which collects data from sensors and put those into a file ... even if the tool has no connection to a terminal. Next step will be to connect a GPS module (ordered) to the GPIO pins of that board (which is quite offtopic and I fear therefore my sole problem... ;). Suppose the GPS would already be attached to the board and works... Is there any free available software and data for strict offline useage (which does NOT calls to home), which is able to map GPS data to a street/land map? I need both: The maps themselves and the logic to read GPS coordinates and map movements and ways to those maps. Is something like that available for free or should I directly ask the NSA/CIA/FBI/...? Thank you very much in advance for any help! Best regards, mcc

I already have a solution in a file which is a user alterable
file:
I just put a call to ntp-client in the postup(){} function
of /etc/conf.d/net. Called once and no polling and straight forward.
And if an update to that file will happen, cfg-update will keep track
of it.
I am happy with that.

You can write software to do this using the proj4 library for an embedded box, not sure if anything for your specific use case already exists and is open source. Alec Sorry iphone send mail even if you don't wanna :/ What you are considering doing is quite a challenge. What kind of coordinates does your gps module give you? The gps system works with cartesian x y z coordinates. Then these are usually displayed to the user in WGS-84. This is a quite hard mathematical problem (differential elliptical problem). Usually is done by your gps receiver and is approximated. GIS libraries have these functions built inside. Distances are easier and faster to calculate in cartesian coordinates. You need to calculate distance because coordinates from gps will never coincide with any address. Open street maps provides a very good start, but addresses have great differences in different countries. For example google misses addresses quite much depending on where you are searching. Getting the address right requires good locality from the program. Addresses and roads are vector maps. The fastest way to get address is to have the vector map of the world and then calculate distance to the closest address. The database will be huge :) Maps are usually raster pictures which have some projection. When you display them you can use 3d or 2d visual. In 3d (like google earth) you draw a sphere (or oblate spheroid) and draw textures on top of is to the right coordinates. In 3d everything needs to be converted to cartesian coordinates. Or in 2d you decide a projection and then convert the projection of your maps to this projection. After that it is just easy drawing. GIS libraries contain all the needed tools for these operations. There are a few of them with open source license. I have been doing some work with opengl 3d drawing maps. Good luck your project is quite big but it is sure very much fun :) -- -Matti

Is there any free available software and data for strict offline useage (which does NOT calls to home), which is able to map GPS data to a street/land map? I need both: The maps themselves and the logic to read GPS coordinates and map movements and ways to those maps. Is something like that available for free or should I directly ask the NSA/CIA/FBI/...? Thank you very much in advance for any help! Best regards, mcc you can also have a look at something like www.openpaths.cc they have an api you can plug into but you need to post your gps data to them doesn't quite fit the offline part but to start it takes a lot of the heavy lifting for you alternatively you could save your gps co-ordinates to an xml file and send that via email, which you can then push up to google maps again, doesn't quite fit the offline part, but i'm not sure how you would visually see your map if it's headless unless if it's on another computer Hi, the offline part is important to me. In times where knowledge slowly and surely becomes a criminal act if created just by interest I am not willing to send any data (like GPS data) to google or others like them. headless vs. see the map: Sorry, the explanation may be missing in my mails. The headless device is only used as GPS recorder, which only stores the GOS data given by GPS module. The visualization is done lateron on my PC... The headless device (Beaglebone black) only has 512MB RAM and 16GB SDcard flash... And the CPU is not made for heavy mathematics... Best regards, mcc

Best regards, mcc The only project I know of that has openly available map data is OpenStreetMap (openstreetmap.org). I know they have an API, and they probably (not sure) have maps available for download. afaik the only way to combine various map data out of the box is to use a GIS package like QGIS. You can write software to do this using the proj4 library for an embedded box, not sure if anything for your specific use case already exists and is open source. Alec Sorry iphone send mail even if you don't wanna :/ What you are considering doing is quite a challenge. What kind of coordinates does your gps module give you? The gps system works with cartesian x y z coordinates. Then these are usually displayed to the user in WGS-84. This is a quite hard mathematical problem (differential elliptical problem). Usually is done by your gps receiver and is approximated. GIS libraries have these functions built inside. Distances are easier and faster to calculate in cartesian coordinates. You need to calculate distance because coordinates from gps will never coincide with any address. Open street maps provides a very good start, but addresses have great differences in different countries. For example google misses addresses quite much depending on where you are searching. Getting the address right requires good locality from the program. Addresses and roads are vector maps. The fastest way to get address is to have the vector map of the world and then calculate distance to the closest address. The database will be huge :) Maps are usually raster pictures which have some projection. When you display them you can use 3d or 2d visual. In 3d (like google earth) you draw a sphere (or oblate spheroid) and draw textures on top of is to the right coordinates. In 3d everything needs to be converted to cartesian coordinates. Or in 2d you decide a projection and then convert the projection of your maps to this projection. After that it is just easy drawing. GIS libraries contain all the needed tools for these operations. There are a few of them with open source license. I have been doing some work with opengl 3d drawing maps. Good luck your project is quite big but it is sure very much fun :) -- -Matti YEAH! Matti is back! I saw your previous mail and thought: Oh boy...Clint Eastwood is very talkative compared to /him/. ;;;))) Trashed the phone... and now back to the good old fashion terminal connection. I am not /that/ serious this evening...sorry... With all the help from this forum this evening I got by far more working results as I have thought... But back to your mail: The GPS module I plan to use is this one (by Adafruit, Lady Ada): https://learn.adafruit.com/adafruit-ultimate-gps/overview From there (see link list on the left) you can also download the manuals (pdf). Nice... MicroTek chipset. Quite easy to use. I will not use this thing as a driving assistant or navi (is this common speaking outside germany also...or is it one of those pseudo english german words like handy for cell phone...dont laugh! This time /I am/ serious! :) ) Its more like a GPS data logger. I plan to copy the gathered data on my PC later and I will try to draw them onto a map. May be the results proof later, that I am able to walk through walls and hovering over the face of the waters...;) Ok. This is easy... You just need some maps... openstreetmaps are good for that. From the MT3339 you get NMEA messages and WGS-84 coordinates. I would suggest displaying your results in 2D. For germany Lambert conformal conic projection is good choice. In this projection all angles are true and sreight lines are great circle routes. Just convert the maps to this projection and convert your coordinates to Lambert false easting and false northing and you will have cartesian coordinates that are easy to draw. Even excel is able to draw this in real time :) I don't see where you need the address resolution. May be the UV-mappinga abillity of this 3D renderig program will help -- I am using it for other purposes
