vitalyster commented 4 years ago

You need to have libglfw3.a to link examples correctly. However, binary glfw distribution for Windows provide this file for msvc and MinGW-W64(msvcrt.dll) and this will not be suitable for llvm-mingw (ucrt.dll) compiler. You need to build glfw from source (just cmake . -D "MinGW Makefiles" && mingw32-make from the same llvm-mingw environment will create suitable libglfw3.a)

I use the MSVC compiler through the build tools that came with Visual Studio to compile things like that. I had to build glad.c with the "x64 native build tools" command prompt which took me a while to figure out.
