[Paraview] Undefined glXGetProcAddressARB

[Kent Eschenberg]

The compile of file VTK/Rendering/vtkOpenGLExtensionManager.cxx fails at line 195 because glXGetProcAddressARB is undefined. A search of CMakeCache.txt for "PROC_ADDRESS" finds

======
VTK_GLX_GET_PROC_ADDRESS_ARB_PROTOTYPE_EXISTS:INTERNAL=TRUE

//Already set VTK_GLX_GET_PROC_ADDRESS_ARB_PROTOTYPE_EXISTS

VTK_GLX_GET_PROC_ADDRESS_ARB_PROTOTYPE_EXISTS_TESTED:INTERNAL=1

VTK_USE_GLX_GET_PROC_ADDRESS_ARB:INTERNAL=1
======

The top of the cxx file mentioned above includes

======
#ifdef VTK_DEFINE_GLX_GET_PROC_ADDRESS_PROTOTYPE
extern "C" vtkglX::__GLXextFuncPtr glXGetProcAddressARB(const GLubyte *);
#endif //VTK_DEFINE_GLX_GET_PROC_ADDRESS_PROTOTYPE
======

and, later, line 195 is inside another ifdef:

======
#ifdef VTK_USE_GLX_GET_PROC_ADDRESS_ARB
  return glXGetProcAddressARB((const GLubyte *)fname);
#endif //VTK_USE_GLX_GET_PROC_ADDRESS_ARB
======

Therefore it looks like cmake set VTK_USE_GLX_GET_PROC_ADDRESS_ARB but not VTK_DEFINE_GLX_GET_PROC_ADDRESS_PROTOTYPE. A few details:

ParaView 2.4.4
Mesa 6.5.2
Pentium 4
gcc 4.1.1
Linux Fedora Core 5

The Mesa includes and libraries include glXGetProcAddressARB.

I could of course change the VTK source code to always define that routine but would like to instead coax cmake to do the right thing. TIA!
