[Paraview] Python interpreter not being created for coprocessing?

[Vanmoer, Mark W]

Hi Andy, that sounds like some deep debugging, thanks for your effort. I'll test this and let you know. It's on my to do list to learn CMake, I've had the book on my desk for a month now.

Also, I made another Fortran example that's closer in spirit to the wiki example, which uses the DataGenerator class as the C++ does, if you're interested.

Thanks,
Mark

Hi Mark,

I finally got around to fixing this. It's in the stage branch (remotes/stage/13460_CP_FortranAdaptor) and hopefully will go into the master branch on the next gatekeeper review. There were 2 issues fixed in this:
1) for using newer GCC compilers and other compilers that hide symbols in the library (http://gcc.gnu.org/wiki/Visibility) the FortranAdaptor API methods weren't available to other libraries and executables trying to link to them.
2) Since 3.14.1 I changed around the way ParaView gets initialized through the coprocessing library (now through vtkCPProcessor::Initialize() as it should be instead of vtkCPPythonScriptPipeline::Initialize()). I forgot to make the change in the FortranAdaptorAPI.cxx which caused the python interpretor to not be initialized properly, as you noticed.

Thanks for the help in finding this problem. Sorry for the slow response on it. I created a CMakeLists.txt file to help build as I've been using CMake too long and can't remember how to work with Makefiles anymore! I'm attaching it in case you'd like to use it. I didn't test it with an install of ParaView as I really only work directly with ParaView builds.

Let me know if this solves your problems. I seem to remember there being more as far as using CUDA and PGI but hopefully this gets you close.

By the way, I'll probably use what you sent me to create a Fortran test or example to help with making sure it doesn't get broken in the future.

Tarball attached, it’s not exactly the wiki example because I didn’t want to bother with passing a DataGenerator object back and forth from C++ to Fortran, so I just make a sphere. The pipeline script is a shrink filter generated by pvclient.

I checked CMake and it looks like it’s finding the same version of python.

Can you send me your Fortran version of the wiki example?
