Hello

The compilation of PV4blockMeshReader give me error saying that Qt was not found:

-- The C compiler identification is GNU 4.8.2
-- The CXX compiler identification is GNU 4.8.2
-- Check for working C compiler: /sw/Defaults/bin/gcc

CMake Error at CMakeLists.txt:46 (QT4_WRAP_CPP):
  Unknown CMake command "QT4_WRAP_CPP".

Adding FIND_PACKAGE(Qt4 REQUIRED) in CMakeLists.txt give good results from configuration and compilation phase but still error during linking:

I try adding ${QT_LIBRARIES} in TARGET_LINK_LIBRARIES but without success.

Any help would be appreciated!

Thank in advance.

Note: Open FOAM and paraview from openFoam are working fine

[12:47:07] nathanael@localhost:$ which paraview
/sw/OpenFOAM/ThirdParty-2.3.x/platforms/linux64Gcc48/ParaView-4.1.0/bin/paraview

Okay, I found the problem: wrong qt version used.

Now it's compiling but paraview refuse to load the plugin:

ERROR: In /sw/OpenFOAM/ThirdParty-2.3.x/ParaView-4.1.0/ParaViewCore/ClientServerCore/Core/vtkPVPluginLoader.cxx, line 302
vtkPVPluginLoader (0x2f704e0): /sw/OpenFOAM/OpenFOAM-2.3.x/platforms/linux64Gcc48DPOpt/lib/libsurfMesh.so: undefined symbol: _ZN4Foam13HashTableCore13canonicalSizeEi

This seems to be related to mantisbt bug_id=195

The patch proposed does not correct the problem for Open FOAM 2.3.x.

Greetings Nathanaël,

I can't figure out if you're using a Linux distribution or Mac OS X .
Can you please provide more information, including an indication of which installation instructions you're following?

Best regards,
Bruno

Hello Bruno,

My distribution is Linux Centos 6.5 and the instruction I follow are those from repository release (http://www.openfoam.org/download/git.php)

As my distrib offer only Qt 4.6.2, I compile Qt from source (not using OpenFOAM script but without differences.)

The first problem was due to wrong Qt version searched (cmake search for Qt in folder '/sw/Qt/qt-4.8.5' and this version was removed and replaced by '/sw/Qt/Qt-4.8.4' after compilation of Paraview). After discovering that I recompile Paraview using OpenFOAM script and PV4Readers. This gives me the dynamic linking problem as described in my previous post.

This night I clean the modified CMakeLists.txt of PV4Readers and now it is working fine!

Thanks for the help and sorry to prevent late for solving my problem.

Nathanaël.
