simgear fg-next :cmake compile error Ubuntu 16.04 x64

Postby yanes » Thu Feb 09, 2017 10:28 pm

Hi guys ,
I'm totally inexperienced in cmake source compiling , and in fact to c/cpp coding as well .
(I did a lot of Pascal for both win & linux and dealt with Deb packaging issues via some alternatives ).
I cloned the flightgear and simgear repos from SF by running :
git clone https://git.code.sf.net/p/flightgear/flightgear flightgear-flightgear
git clone https://git.code.sf.net/p/flightgear/simgear flightgear-simgear

and run in the simgear clone :
Code: Select all
mkdir build-sg
cd build-sg
cmake -D CMAKE_INSTALL_PREFIX:PATH="$prefix" ~/Documents/fgsrc/flightgear-simgear


the latter command failed with the following output :
Code: Select all

It looks like it's searching for Open-GL symbols, lib paths or may be a someOpenGLpackage-dev (no clue!!).
So how to solve the issue?

thanks in advance ,

Try installing libgl1-mesa-dev and mesa-common-dev:
Code: Select all
sudo apt-get install libgl1-mesa-dev mesa-common-dev

Thank you @elgaton this solved the issue , simgear compiled linked successfully .
(there was some other issues due to lack of some -dev packages on my system, but when installed every thing went fine .

However, when coming to flightgear source, the make process ("cmake -D CMAKE_INSTALL_PREFIX:PATH="$prefix" ~/Documents/fgsrc/flightgear-flightgear")
finshed successfully, but the linking/install process aborted with
Code: Select all
/home/xx/Documents/fgsrc/flightgear-flightgear/utils/fgelev/fgelev.cxx:30:35:
fatal error: simgear/props/props.hxx: No such file or directory
compilation terminated.
utils/fgelev/CMakeFiles/fgelev.dir/build.make:62: recipe for target 'utils/fgelev/CMakeFiles/fgelev.dir/fgelev.cxx.o' failed
make[2]: *** [utils/fgelev/CMakeFiles/fgelev.dir/fgelev.cxx.o] Error 1
CMakeFiles/Makefile2:442: recipe for target 'utils/fgelev/CMakeFiles/fgelev.dir/all' failed
make[1]: *** [utils/fgelev/CMakeFiles/fgelev.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs
....
....
Makefile:149: recipe for target 'all' failed
make: *** [all] Error 2

To be fair , I tried to make a link of simgear source dir in the flightgear src dir but other errors popped out so ,
please tell me if I'm missing somtething .

Thanks in advance
Yanes Bechir.

After compiling SimGear, did you install it into your prefix by running "make install"?

AFAICS there were changes recently int that area of code, mayhap you just cloned the source at a bad time. Try updating it: http://wiki.flightgear.org/FlightGear_G ... it_current

Also, I assume $prefix is the same for both, SG and FG?

The past few days the ML ran hot with problems compiling FG on linux. The issue should™ be fixed now. So, update the source and try again.

Make sure the build directories are clean (ideally rm -Rf * there) before running the cmake commands.

The wiki's Debian page has a tad more explanation on how to compile it, though basically it's the same as the link to Ubunut you've posted earlier. All the commands there are made to just copy'n'paste them into the console. Except for the two 'export' ones, which define src and install dirs. If you go through that guide step by step (the plib step can be omitted), without altering anything except you really know what you're doing, and the process still fails, please run the cmake and make commands as such:

cmake -D CMAKE_INSTALL_PREFIX:PATH="$FG_INSTALL_DIR" $FG_SRC_DIR/simgear.git 2>&1 | tee SG_cmake.log
make -j2 && make install 2>&1 | tee SG_make.log
cmake -D FG_DATA_DIR:PATH="$FG_INSTALL_DIR/fgdata" -D CMAKE_INSTALL_PREFIX:PATH="$FG_INSTALL_DIR" $FG_SRC_DIR/flightgear.git 2>&1 | tee FG_cmake.log
make -j2 && make install 2>&1 | tee FG_make.log

Paste the resulting .log files on some pastie (like https://dpaste.de/) so we can have a look at them. Make sure, the pastes will stay online for a week at least. Also, sometimes there are knowledgeable people on IRC who are willing to help in such cases. IRC makes it a bit more interactive which might speed things up with odd compilation issues.

Re-pulling the source tree solved the issue really ,

@C032H272JB: no one can help you further because of the lack of requested information in your other topic(s)... your paranoia is too high... my systems are connected 24x7 and we've had no problems with infestations but we've all been trained not to click on random guff that comes up... we filter everything but things like FG don't really face such problems... it is just not the low hanging fruit like winwhatever and other things are...
