Re: [Chromium-users] Re: [Chromium-dev] Raptor released

[Mike H. <mho...@gr...>]

Hmmm...  For linux, I use glXGetProcAddress which should be everywhere. 
  On windows, wglGetProcAddress *should* work.  Does anyone know what 
the standard really is here?

If GetProcAddressARB works for everyone, that's an easy code fix.

Dave: Which lines in the raptor code are you changing?

Thanks,
Mike
