I did not tested it with pre-compiled ParaView/VTK binaries ... but it should work in theory. You need to make sure that there are VTK shared libraries and that they are in your LD_LIBRARY_PATH and so the Python bindings which must be in your PYTHONPATH variable. But you will need cmake for configuration and a C++ compiler (only tested with GNU compiler collection C++ compiler). I think there is no way around the compilation HowTo. > > Also, do I need to put this anywhere in particular or will make install do it > for me? Make install should do the job, as /usr/local is the default installation location which should be automatically in your path on a Linux machine.
