[vtkusers] Which compiler and settings on SGI

[Mathieu Malaterre]

Martin,

	Looks like you are configuring VTK with one compiler then using another 
one. Could you try instead directly specifying which compiler you really 
want:

export CC=/stripe1/segment/UNSUPPORTED/gcc-2.95.3/bin/gcc
export CXX=/stripe1/segment/UNSUPPORTED/gcc-2.95.3/bin/g++

(make sure the directory is empty)
mkdir VTK-gcc295
cd VTK-gcc295
cmake /full/path/to/VTK
