[Paraview] libQtHelp.so.4 error

[Magician]

Hi Utkarsh,


I had been trying to solve libQtHelp errors.
Finally I succeeded to run my ParaView.

I missed two important settings.
First one was about Qt.
Qt 4.6.2 was pre-installed on CentOS 6.2 and I additionally
installed Qt 4.6.4 from tarball, so both versions of Qt were
mixed on my CMake setting.
My old ParaView on CentOS 6.2 looked no problem, but it referred
pre-installed Qt 4.6.2.
On the other hand, CentOS 5.3's Qt was 3.3, so it couldn't be
referred from ParaView (it was already built with Qt 4.6.4).
When I changed QT_QMAKE_EXECUTABLE as /usr/local/bin/qmake from
/usr/bin/qmake-qt4 (pre-installed qmake) and re-configured
on CentOS 6.2, all Qt settings were updated.

Second one was about LD_LIBRARY_PATH as you mensioned.
My ParaView (built with Qt 4.6.4) still dumped libQtHelp errors.
If I did "export LD_LIBRARY_PATH=/usr/local/lib", my ParaView ran.
And also I modified /etc/ld.so.conf, they ran too.

Thanks for your advices!!
