[swift-users] Swift can’t compile code with OpenGL function pointers

[Kelvin Ma]

OpenGL functions are loaded at runtime by a function loader (like GLFW).
They’re defined in a header but obviously they don’t have definitions at
compile time so it causes a slew of linker errors when I try to build

    error: undefined reference to 'glEnable'
    error: undefined reference to 'glBlendFunc'
    error: undefined reference to 'glClearColor'
    clang: error: linker command failed with exit code 1 (use -v to see
invocation)
    ...

How do I build programs that use OpenGL functions?
