[vtkusers] VTK compile error: gcc 3.32, Solaris 10

[Francois Bertel]

Hello Stephen,

At line 261 of VTK/Rendering/vtkOpenGLExtensionManager.cxx,

can you replace the first static_cast by a reinterpret_cast, please?

Just replace this line:

return static_cast<vtkOpenGLExtensionManagerFunctionPointer>(glXGetProcAddress(reinterpret_cast<const
GLubyte *>(fname)));
by this line:
return reinterpret_cast<vtkOpenGLExtensionManagerFunctionPointer>(glXGetProcAddress(reinterpret_cast<const
GLubyte *>(fname)));

and tell me if it passes. I need your feedback for fixing VTK-5.2 and VTK CVS.

Regards.
