[Paraview] ParaView Catalyst and running example codes ...

[Ufuk Utku Turuncoglu (BE)]

Hi,

I am trying to run ParaViewCatalystExampleCode under Mac OS 10.10.2. I 
have already installed

Catalyst-base+essentials+extras+renderingbase+python-Source.tar

to my machine successfully and i would like to test the example codes. 
The main problem is that i am getting following error when i try to run 
the FortranPoissonSolver

epsilon:FortranPoissonSolver turuncu$ ./FortranPoissonSolver coproc.py
Error: Cannot import vtkPVServerManagerDefaultPython
Error: Cannot import vtkPVAnimationPython
...
...

i also created following shell script to run the example

CATALYST="/Users/turuncu/Qsync/progs/catalyst"
export PYTHONHOME="$CATALYST/lib"
export PYTHONPATH="$CATALYST/lib:$PYTHONPATH"
export PYTHONPATH="$CATALYST/lib/site-packages:$PYTHONPATH"
export PYTHONPATH="$CATALYST/lib/site-packages/paraview:$PYTHONPATH"
export PYTHONPATH="$CATALYST/lib/site-packages/vtk:$PYTHONPATH"

export LD_LIBRARY_PATH="$CATALYST/lib:$LD_LIBRARY_PATH"
export DYLD_LIBRARY_PATH="$CATALYST/lib:$DYLD_LIBRARY_PATH"

./FortranPoissonSolver coproc.py

but in this case, it complains as "ImportError: No module named site". I 
think that it might be realted with the definition of PYTHONHOME 
environment variable and somehow it causes problem in Python side. 
Anyway, i am using Enthought, Canopy (64bit) for python implementation 
under Mac OS and i also tried to add PYTHONPATH to shell script to 
define Canopy related modules

export 
PYTHONPATH="/Applications/Canopy.app/appdata/canopy-1.4.1.1975.macosx-x86_64/Canopy.app/Contents/lib/python2.7:$PYTHONPATH"

but again i am getting following error which could be related with the 
wrong definition of environment variables or their orders because sys 
has base_prefix method (tested under ipython)

...
...
     from sysconfig import get_config_var
   File 
"/Applications/Canopy.app/appdata/canopy-1.4.1.1975.macosx-x86_64/Canopy.app/Contents/lib/python2.7/sysconfig.py", 
line 95, in <module>
     _BASE_PREFIX = os.path.normpath(sys.base_prefix)
AttributeError: 'module' object has no attribute 'base_prefix'

So, i just wonder that is there anybody that run these examples under 
MacOS along with Enthought, Canopy? Is there any custom script to run 
the example? Do you suggest me to go directly to Linux (i.e. Centos 
etc.) to solve these problems.

Thanks,
