seems GL_GLEXT_PROTOTYPES not defined.

Indeed, I have added is to ngl.h just before including gl.h. Can you pull the change and let me know if the fix works?

gluBuild2DMipmaps was declared in 'glu.h', why commented # include <GL/glu.h>(include/ngl.h:501)?
I uncommented it, compilation passed but other errors occured as follow:
