paraFoam not compilet due to QT4 not found
 

Hi,

I am trying the installation of OpenFoam 2.0.1 on CentOS.

I have strictly followed the installation steps, and solved a lot of problems with XML, openGL, cmake, ...

I am in the final step compiling the VTK plugins for paraview and have paraFoam running.

When I execute $FOAM_INST_DIR/applications/utilities/postProcessing/graphics/PV3Readers/Allwmake the script gives the following output:
...
+ cmake ../..

-- The CXX compiler identification is GNU

CMake Error at CMakeLists.txt:43 (QT4_WRAP_CPP):
Unknown CMake command "QT4_WRAP_CPP".

-- Configuring incomplete, errors occurred!

I have tried the following:

1) Include /usr/lib63/qt4/bin in the PATH.
2) Recompiling cmake.
3) Recompiling qmake.

Nothing of above has been useful.

It seems QT4 location must be declared somewhere but I don't know where. :confused:

Any idea somebody?

Finally solved
 

I finally fixed the problem following the instructions contained in the thread HowTo Make paraFoam from OpenFOAM15 work on OpenSuse11 by installing Qt435 in home directory.

So I reinstalled QT4 by executing:

$FOAM_INST_DIR/../Thirdparty-2.0.1/qt-everywhere-opensource-src-4.6.4/make confclean
$FOAM_INST_DIR/../Thirdparty-2.0.1/qt-everywhere-opensource-src-4.6.4/.configure
$FOAM_INST_DIR/../Thirdparty-2.0.1/qt-everywhere-opensource-src-4.6.4/gmake (it took 4 h, more or less)
$FOAM_INST_DIR/../Thirdparty-2.0.1/qt-everywhere-opensource-src-4.6.4/gmake install (it took 0.5 h, more or less)

A difference with the Post "How to make...": When I modified PATH within $FOAM_INST_DIR/etc/bashrc, ParaView did not work properly: the fonts were not displayed. So I kept it unmodified.

Then, reinstalled ParaView:

$FOAM_INST_DIR/../Thirdparty-2.0.1/makeParaview

And finally built paraFoam plugins:

$FOAM_INST_DIR/applications/utilities/postProcessing/graphics/PV3Readers/Allclean
$FOAM_INST_DIR/applications/utilities/postProcessing/graphics/PV3Readers/Allwmake

And I got paraFoam working fine !!! :)
