in freeglut 3.0.0 there no configure file. received error when compiled free glut (2.8.0) using (env cppflags="-i/opt/x11/include" ldflags="-l/opt/x11/lib" ./configure) guide

a question related not helping is possible build freeglut on mac os x?

you open progs/demos/smooth_opengl3/smooth_opengl3.c , search pfnglgenbuffersproc

now comment out #ifndef gl_version_1_5 , #ifndef gl_version_2_0 clauses. rebuild , errors should gone.
