Hi,
I am playing with GNUstep for some hours now and I still wondering about
3 things that I discarded at start.
** 1. Using GNUstep,
CGDisplayIDToOpenGLDisplayMask(kCGDirectMainDisplay) seems to be not
supported.
(...)
CG* functions are Apple specific. Look for WGL similar functions on
Windows, or for GLUT or SDL functions. This is not a GNUstep related issue.
** 2. CGCaptureAllDisplays and CGReleaseAllDisplays seem to be not
supported on GNUstep.
(...)
This may help:

** 3. How can I check at runtime if a function is implemented by the
platform backend ?
For example "setValues" is not implemented on win32:
[[self openGLContext] setValues:&swapInterval
forParameter:NSOpenGLCPSwapInterval];
A call to a non-implemented method raises an exception. You may catch
it. As it's only implemented by Apple a compile time check should do the
job. But is this what you need ?
Once again you might have to look for WGL functions
See WGL_EXT_swap_control. This is an extension and might not be
supported by some old PC hardware.
'back/Source/win32/w32_GLcontext.m' might be the place to put your
changes in ;)
Regards
