[Paraview] Re: [vtkusers] Unable to Compile VTK in 64 Bits Linux

[Kent Eschenberg]

You may be right. I thought the library would be 64-bit 
since the path to it

/usr/lib/gcc/x86_64-redhat-linux/3.4.6/../../../libGL.so

includes "x86_64". I'd suggest Xin Guai first try your 
suggestion then, if needed, mine.
