[Ajaya_Kumar <Ajaya_Kumar Bla Satyam com>]

Hi,
 	I am realy finding problem in interfacing with gtk and opengl, I
included  "gtkgl/gtkglarea.h" and I am getting the following error message
from VC++ 6.0


The error message
----------------------------------------------------------------------------
----------------------------------------

c:\program files\microsoft visual studio\vc98\include\gl\gl.h(1151) : error
C2144: syntax error : missing ';' before type 'void'

Would you guide me  to use gtk as GUI and opengl as backend.

Looking for your feed back
