[vtkusers] Undefined reference to Mesa

[Hassan Amin]

For ldd kitware/VTK_Build/bin/libvtkRendering.so | grep OSMesa

I get : libOSMesa.so.7 => not found

How did I built Mesa library :

I used ./configure
and make to build my Mesa library.

I am unable to make Mesa using following commands :

"cd Mesa-7.6.1/
make linux-x86-64"

which was recommended earlier.



Regards,


Dr. Hassan Amin
