[Paraview] cannot find -lvtkPVPythonCatalyst error when doing coprocessing

[Hong Yi]

Hi Andy,

Just let you know that I am able to work around the error by adding an option in CMake to allow users to specify the static PhastaAdaptor lib to link to and I am able to build our simulation code linked to ParaView coprocessing successfully. Let me know if you know a better way to do it.

Thanks,
Hong

Hi Andy,

That seems to work well, but just to double make sure, let me copy the list of relevant coprocessing libs for 3.98 for your perusal:
----------------
libvtkCoProcessorCS-pv3.98.a
libvtkCoProcessorPython27D-pv3.98.a
libvtkCoProcessorImplementation-pv3.98.a
libvtkCoProcessorPython-pv3.98.a
libvtkCoProcessor-pv3.98.a
----------------

On a related question, now I am getting error "cannot find -lPhastaAdaptor" although I have libPhastaAdaptor.a in the lib directory. It looks like it tries to link to shared library rather than the static library. I am using "find_package(ParaView 3.98 REQUIRED COMPONENTS vtkCoProcessorImplementation PhastaAdaptor)" followed by "target_link_libraries(phastaIC.exe vtkCoProcessorImplementation PhastaAdaptor)" in CMakeLists.txt file. What else should I do or correct to make the linker to link to libPhastaAdaptor.a (as it did for other coprocessing-related static libs) rather than link to shared lib via -lPhastaAdaptor?

Thanks and best regards,
Hong

Hi Hong,

The Catalyst User's Guide corresponds to ParaView 4.0 and later. You're correct that for 3.98 you'll need to link to one of the CoProcessing libraries. If I recall correctly, you should use:

TARGET_LINK_LIBRARIES(phastaIC.exe vtkCoProcessorImplementation)

If that doesn't work, can you email me the list of CoProcessing libraries in your build tree?

Regards,
Andy

When building our simulation code linked to ParaView 3.98 (built with coprocessing enabled) with CMake, I got the error "cannot find -lvtkPVPythonCatalyst" in the final linking stage. I followed Catalyst User Guide to add the following into CMakeLists.txt to handle coprocessing:

------------------------------------------
...
find_package(ParaView 3.98 REQUIRED COMPONENTS vtkPVPythonCatalyst PhastaAdaptor)
include("${PARAVIEW_USE_FILE}")
add_definitions("-DUSE_CATALYST")
...
target_link_libraries(phastaIC.exe vtkPVPythonCatalyst PhastaAdaptor)
...
------------------------------------------

I verified there is no vtkPVPythonCatalyst lib in the ParaView build, although there are a few coprocessing-related libs there in the ParaView build. Should I change vtkPVPythonCatalyst to some coprocessing-related component? If so, which component name should I use? I need to use python for pipeline handling and link catalyst to fortran code.

Thanks for any tips you can provide!

Hong
