Build fails on 64-bit arch

[cvigano]

When building this project using instructions from the readme, I get the following error:

music_and_sound_openal.cpp:(.text._ZN9__gnu_cxx13new_allocatorISt13_Rb_tree_nodeISt4pairIKS2_IbiEjEEE8allocateEjPKv[_ZN9__gnu_cxx13new_allocatorISt13_Rb_tree_nodeISt4pairIKS2_IbiEjEEE8allocateEjPKv]+0x45): undefined reference to `operator new(unsigned int)'
/usr/bin/ld: CMakeFiles/graphics.dir/g_src/basics.cpp.o: file class ELFCLASS32 incompatible with ELFCLASS64
/usr/bin/ld: final link failed: File in wrong format

make[1]: *** [CMakeFiles/graphics.dir/all] Error 2
Makefile:75: recipe for target 'all' failed
make: *** [all] Error 2

System is Arch Linux on x86_64 with all necessary libraries installed in their respective 32-bit variantt

Reverting 10acd34 fixed this error for me. Seems like this is necessary for some libraries to get linked correctly as opposed to what you said in #2.

Do you need more information?

Solved.
