FreeOrion

Hi,

compiling the freeorion rv4217 i get the next error :


/usr/bin/ld: CMakeFiles/freeorion.dir/__/__/UI/CUIControls.cpp.o: undefined reference to symbol 'glTranslated'
/usr/bin/ld: note: 'glTranslated' is defined in DSO /usr/lib/libGL.so.1 so try adding it to the linker command line
/usr/lib/libGL.so.1: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

make[1]: *** [client/human/CMakeFiles/freeorion.dir/all] Error 2
make: *** [all] Error 2

Looks like you need to add -lGL to the linker command. Presumably there's a way to do that through CMake or editing the make file...

I added in various make files the -lGL command and doesn't work.

when i do a cmake . this is the result :

Its OK?

If you rerun cmake after editing make files, it may have overwritten them...

Did adding the -lGL change the resulting calls to the linker? How did it not work?

I know if you run cmake the make files are overwritten , i don't know what make files i have to add the -lGL. I added to one that doesn't work but there are many make files.

Sorry if I my explanation is so bad but my english is very bad, he he he.

Thank very much for your responses.

The solution is in the CMakeCache.txt :

CMAKE_CXX_FLAGS:STRING=-lGL <-- added

I don't know why the cmake dont add this field automatically.

Thank you very much for the response.

Hello!

I get a similar error during compile:

Linking CXX executable ../../freeorion
/usr/bin/ld: CMakeFiles/freeorion.dir/__/__/UI/SidePanel.cpp.o: undefined reference to symbol 'gluQuadricTexture'
/usr/bin/ld: note: 'gluQuadricTexture' is defined in DSO /usr/lib64/libGLU.so.1 so try adding it to the linker command line

I ran cmake with the options -DCMAKE_CXX_FLAGS:STRING=-IGL, but the same error appeared. I also tried the option -IGLU, and both together -IGL -IGLU. Neither of this options changed anything, any idea what to do about it?

Thanks in advance.

Probably same here:



How can i link libGLU.so.1?

Did you try the methods suggested earlier in this thread?
