Hi

This one finally worked out
(I love replying to my own postings ;)

It turns out that when using MEX you need to explicitly specify the libraries GL, GLU and glut

ie:

mex -v -lGL -lglut -lGLU mexRender.c

although compiling in gcc seperately would require only the '-lglut' option.
(mex -v -lglut mexRender.c will complain of unresolved stuf...)

hope this saves someone the time I wasted away :)

Best regs

Srimal.

Thanks for posting that, Srimal. It will most certainly come in handy.

Were you successful in creating the graphic window Srimal?
I have another thread that described a crash in a R2008 of Matlab as
soon as you tried to create a GLUT context.
