Using chicken scheme, i installed some 'eggs', but when trying to use any procedure from them, the procedures name is never bound to an actual procedure. For example, on the csi interpreter:
#;1> (import glfw3)
#;2> (init)
Error: unbound variable: glfw3#init
The same thing happens with any procedure or value from any other 'egg' that I've tested, both in the interpreter and the compiler; nothing from any 'egg' ever gets bound.
Do you happen to be using CHICKEN 4? If so, you probably need (use glfw3) instead of (import glfw3). If you are using CHICKEN 5, (import glfw3) is correct and init should work.
