Doesn't compile demos of GF 3D for a Photon   
Good time. I've downloaded Photon OpenGL ES demos demonstrating use of GF 2D/3D from http://community.qnx.com/sf/frs/do/
viewRelease/projects.graphics/frs.photon.gf_ph_2d, 
and I tried to compile gears.c source under QNX650-host by:
#qcc -V gcc_ntox86 gears.c -lgf -lGLES_CM

But it generates error like:
.../crt1.o (text+0x04) Undefined reference to 'main'
.../crt1.o (text+0x86) In function _start:
Undefined reference to 'main'

This source of demo seems simple enough, but...
Please advise me how to compile OpenGL ES gears.c .

You must compile with PhAB (Photon App Builder), there is no 'main()' in gears.c, it is a PhAB project.

OK, is this possible to compile(and to run) any Mesa demos on QNX650?

No, it is not possible to directly compile Mesa demos, the QNX stack is not based on Mesa.

Regards.

OK. Now I try to remake Linux glx-gears.c for compiling on QNX. Current error is "GLAPI does not name a type" in glues.h
 and glu.h . May I to fix this bug?
Best regards...

I suppose that it needs some header file, but what is? Standart Neutrino's GF,GLES and GLUES is  all included, it is 
must be some header file from extra library, I guess?

Just it needed some extra libraries. Sorry.
