MinGW w64 GCC 5.3 gl/functions.cpp "too many sections (33420)"

[kkitsune]

I just moved to the latest commit from master and I can't even compile it!

I'm on Windows 10 x64, using MSYS2's GCC 5.3 64-bit and the compiler throws this :

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/5.3.0/../../../../x86_64-w64-mingw32/bin/as.exe: CMakeFiles\glbinding.dir\source\gl\functions.cpp.obj: too many sections (33420)
C:\Users\Daniel\AppData\Local\Temp\cc7Qbbhg.s: Assembler messages:

C:\Users\Daniel\AppData\Local\Temp\cc7Qbbhg.s: Fatal error: can't close CMakeFiles\glbinding.dir\source\gl\functions.cpp.obj: File too big

I'm searching on a way to fix this, but is there anyone that can help?

Found it! By adding

-Wa,-mbig-obj

I was able to compile it (it's long as hell but working). Now, how to integrate it in the build system?

[scheibel]

We are aware of this issue, that's why we integrated a workaround for the bigobj requirement in https://github.com/cginternals/glbinding/blob/master/source/glbinding/CMakeLists.txt. Seems like made an error in matching the compilers where we split the heavy cpp files. I'll provide a fix soon.

Does this PR solve the issue for you? #136

[kkitsune]

Yep! That did it! Thanks a lot
