[Paraview] compile itk (VTKGlue ON) with vtk from paraview

[Dr. Roman Grothausmann]

Dear mailing list members,


What configuration is needed to compile itk (4.6.1) with VTKGlue enabled with 
vtk from paraview (4.3.1) in order to compile Paraview plugins making use of ITK 
and VTK?


If I configure ITK to with:
BUILD_SHARED_LIBS                ON
Module_ITKVtkGlue                ON
VTK_DIR                          /opt/paraview-4.3.1_git/lib/cmake/paraview-4.3

cmake complains about a missing VTKTargets.cmake even though 
PARAVIEW_INSTALL_DEVELOPMENT_FILES was set to ON. After a

cp VTK/VTKTargets.cmake /opt/paraview-4.3.1_git/lib/cmake/paraview-4.3/

cmake is happy but I get linker errors at the end of the compilation of ITK when 
the VTKGlue is due:

Linking CXX shared library ../../../../lib/libITKVtkGlue-4.6.so
/usr/bin/ld: cannot find -lvtkSciberQuest
/usr/bin/ld: cannot find -lvtkEyeDomeLighting
/usr/bin/ld: cannot find -lvtkQvis
/usr/bin/ld: cannot find -lvtkPointSpriteRendering
/usr/bin/ld: cannot find -lvtkPVPythonCatalyst
/usr/bin/ld: cannot find -lvtkPointSpriteGraphics
/usr/bin/ld: cannot find -lvtkUtilitiesPythonInitializer


Switching off all PV plugin builds only leaves:

Linking CXX shared library ../../../../lib/libITKVtkGlue-4.6.so
/usr/bin/ld: cannot find -lvtkPVPythonCatalyst
/usr/bin/ld: cannot find -lvtkUtilitiesPythonInitializer

However, the files are there:

find /opt/paraview-4.3.1_git/ -name '*vtkPVPythonCatalyst*so*'
/opt/paraview-4.3.1_git/lib/paraview-4.3/site-packages/vtk/vtkPVPythonCatalystPython.so
/opt/paraview-4.3.1_git/lib/paraview-4.3/libvtkPVPythonCatalyst-pv4.3.so.1
/opt/paraview-4.3.1_git/lib/paraview-4.3/libvtkPVPythonCatalystPython27D-pv4.3.so.1
/opt/paraview-4.3.1_git/lib/paraview-4.3/libvtkPVPythonCatalyst-pv4.3.so
/opt/paraview-4.3.1_git/lib/paraview-4.3/libvtkPVPythonCatalystPython27D-pv4.3.so

find /opt/paraview-4.3.1_git/ -name '*vtkUtilitiesPythonInitializer*so*'
/opt/paraview-4.3.1_git/lib/paraview-4.3/libvtkUtilitiesPythonInitializer-pv4.3.so.1
/opt/paraview-4.3.1_git/lib/paraview-4.3/libvtkUtilitiesPythonInitializer-pv4.3.so


Adding the abs. file locations to the build command does not help nor does 
-L/opt/paraview-4.3.1_git/lib/paraview-4.3/


Using the build dir of VTK in PV-tree instead for ITK does not help either:
VTK_DIR                          /opt/compilation/ParaView-v4.3.1/build/VTK



If I configure ITK to with:
BUILD_SHARED_LIBS                OFF


I get linker errors in the last stage when compiling a PV plugin that makes use 
of VTK and ITK:

/usr/bin/ld: 
/opt/compilation/InsightToolkit-4.6.1/build/lib/libitkvnl_algo-4.6.a(vnl_real_eigensystem.cxx.o): 
relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a 
shared object; recompile with -fPIC
/opt/compilation/InsightToolkit-4.6.1/build/lib/libitkvnl_algo-4.6.a: could not 
read symbols: Bad value

After I've added
CMAKE_CXX_FLAGS                  -fPIC

to Paraview and ITK and recompiled both I get:

/usr/bin/ld: 
/opt/compilation/InsightToolkit-4.6.1/build/lib/libitkv3p_netlib-4.6.a(dlamch.c.o): 
relocation R_X86_64_32 against `.bss' can not be used when making a shared 
object; recompile with -fPIC
/opt/compilation/InsightToolkit-4.6.1/build/lib/libitkv3p_netlib-4.6.a: could 
not read symbols: Bad value


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.
