Hi,

I am trying to build static library of GLFW3 for Linux x86. I am trying to build it on 64 bit machine (Don’t ask why 😀). And I am newbie with Makefile and CMake and all that stuff. I was finding setting of processor architecture in these files but I failed. Does anyone know how I can build GLFW3 from source code for 32 bit Linux?

Thanks for answeres.

I solved my problem myself. After hard googling 😀 I found that you can just add “set (CMAKE\_C\_FLAGS “-m32”)” to CMakeLists.txt to force compiler to build all files for 32 bit system.
