Re: Re: [Chromium-dev] Raptor released

I only changed one line in raptor.cpp (225):

#define GETPROCADDRESS(x) glXGetProcAddress((const GLubyte*) x)

to

#define GETPROCADDRESS(x) glXGetProcAddressARB((const GLubyte*) x)

I also did a 'strings /usr/lib/libGL.so', and the only glXGetProcAddress 
that was listed was glXGetProcAddressARB (ie: nothing listed with the ARB 
stripped).
