Did you check if  the OpenGL demo in fltk test directory work for you?
You can try fltk/tests/fullscreen or cube
if GL is disabled there is a black window with a message saying so.

Or check the file config.h in fltk directory you should have a line with:
#define HAVE_GL 1
It looks like you compiled fltk without OpenGL.

You might need to install Mesa to get OpenGL development files necessary to
properly compile fltk, but I am not sure about it.
