are there any concrete, tangible advantages of glfw over freeglut? I see the glut api as the paragon of usefulness and simple elegance, and I'm really curious how glfw can be any better than that.
I haven't used glfw, but from the docs it leaves you in control of the main loop, whereas glut takes that over and only offers you callbacks. When I used glut (many many years ago) that was sometimes annoying.
glfw doesn't seem to have a function to draw teapots though, which should really rule it out as a serious contender.
There are plenty. Freeglut not being in active development for a while, AFAIK, will not support high-dpi devices (where the window resolution and surface resolution do not match), or newer drivers for different input devices. Freeglut locks you in to OpenGL instead of other rendering APIs. Getting multi-monitor setups up and running is harder. Joystick support is paltry to nonexistent.
