Did You use BUILD_SHARED_LIBS ON for both ITK and ParaView? ITK also
compiles fine without any errors for me if I use BUILD_SHARED_LIBS OFF,
however the problems then arise when compiling the plugin.
I was using BUILD_SHARED_LIBS for both. What issue were you seeing?
If I configure ITK with:
BUILD_SHARED_LIBS ON
Module_ITKVtkGlue ON
VTK_DIR /opt/compilation/paraview-git_build/VTK/
cmake is happy but I get linker errors at the end of the compilation of ITK when
the VTKGlue is due. After switching off all PV plugin builds leaves:
Linking CXX shared library ../../../../lib/libITKVtkGlue-4.6.so
/usr/bin/ld: cannot find -lvtkPVPythonCatalyst
/usr/bin/ld: cannot find -lvtkUtilitiesPythonInitializer
Both libraries seem to be missing entries in
/opt/compilation/paraview-git_build/VTK/VTKTargets.cmake
I guess that's why the linker cannot find these libraries which are there but
with the ending *-pv4.3.so. So a
cd /opt/compilation/paraview-git_build/lib/
for i in *-pv*.so; do ln -s $i ${i%-pv*}.so; done
did the trick but I guess that's not the way it ought to be done.
My guess is that either some lines need to be added to VTKTargets.cmake or that
the ITK-build needs to be told that there is no need to link against these
libraries for the ITKVtkGlue (if that is true).
Again, I think the best approach is to build VTK separately, then
build both ParaView and ITK against that version.
OK, I tried that with vtk-git of today but then paraview cmake complains:
cmake -DUSE_EXTERNAL_VTK:BOOL=ON ../paraview-git/
-- Determined Source Version : 4.3.1-18-g04df19f
-- Using External VTK from "/opt/vtk-git_150202/lib/cmake/vtk-6.2"

-- Configuring incomplete, errors occurred!
I also tried a VTK-6.1 but that just yielded other errors.
How do I figure out what VTK-version ParaView needs? Otherwise I think this is
not a suitable instruction to give in the publication as the VTK-Version needed
is likely to change in future ParaView releases.
Therefore I prefer instructions that use the VTK bundled with ParaView.
What could be the reason that You did not have the linker problems when
ITKVtkGlue was compiled?
Again, many thanks for looking into this.

Hi Roman,
Thanks for the update. Great to hear about the Midas Journal article!
I do not think the Midas Journal will be able to build your plugin.
I would recommend creating build instructions to build against a
ParaView build tree. I have just verified that ITK builds with the
ITKVtkGlue module ON when pointing VTK_DIR to the <ParaView-build>/VTK
directory.
I don't see the install tree VTKTargets.cmake file in my ParaView
build, either. In the long term, the ParaView CMake configuration
should be corrected.
HTH,

Hi Matt,
Thank You very much for Your reply.
I can only find one VTKTargets.cmake in
/opt/compilation/paraview-git_build/VTK/
It seems though that it is lacking the relevant entries for the libraries
that troubled me, e.g. vtkPVPythonCatalyst and
vtkUtilitiesPythonInitializer.
I'm about to publish the ITK-VTK PV plugin in the Midas Journal, what
installation instructions should I give there?
Will the testing environment be able to compile this plugin and its tests
or
should I disable automatic testing for this contribution?
Many thanks for looking into this.

Hi Roman,
Thanks for looking into the issue and reporting it to the mailing list.
Paraview should be installing VTKTargets.cmake, which tells the build
system where to find the libraries. Note that there might be two
VTKTargets.cmake files that are generated -- one for the build tree
and one for the install tree.
HTH,
Matt

Adding the abs. file locations to the build command does not help nor

I figured that the vtk dynamic libraries of PV have the ending
*-pv4.3.so
which seems to be the reason why the linker does not find them. If I
create
symbolic links to these files without the extension:
cd /opt/compilation/paraview-git_build/lib/
for i in *-pv*.so; do ln -s $i ${i%-pv*}.so; done
and adding -L/opt/compilation/paraview-git_build/lib/ to
CMAKE_CXX_FLAGS
the compilation of ITK succeeds.
I wonder, is that the way it's meant to be done?
What am I missing in my configuration of PV and ITK?
When and where should I specify:
CMAKE_CXX_FLAGS -fPIC
BUILD_SHARED_LIBS ON/OFF
Is this the right VTK_DIR specification for ITK:
/opt/compilation/ParaView-v4.3.1/build/VTK
or
/opt/paraview-4.3.1_git/lib/cmake/paraview-4.3
Many thanks for any help or hints.
