I am trying to build ParaView 5.4.0 with PARAVIEW_BUILD_QT_GUI=ON as a part of OpenFOAM 5.0. And I am getting an error:

/home/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/VTK/GUISupport/Qt/QVTKWidget.cxx:50:11: fatal error: QX11Info: No such file or directory

# include <QX11Info>
^~~~~~~~~~
compilation terminated.

I think my QT 5.6.2 built is correctly and I can see QX11Info there:

$ ls Qt5/include/QtX11Extras/
QX11Info QtX11Extras QtX11ExtrasDepends QtX11ExtrasVersion qtx11extrasglobal.h qtx11extrasversion.h qx11info_x11.h

So how do I point ParaView to QT headers?

You have also to install QtWebkit. As far as I know it is not included in the QT distribution.

Quick question @stasserg: With Linux Distribution and version are you using?

Thanks for the answers.

I actually found a solution my problem, after talking to ParaView developers. My VTK_USE_X was set to OFF.

I also was missing libGL.so (I build latest mesa from source) so my Qt5.6.2 was not building properly.

After addressing these 2 I was able to build ParaView, and PVReaders afterwards.

Dear Stas,

I have the exact same problem:
/home/OpenFOAM/ThirdParty-5.0/ParaView-5.4.0/VTK/GUISupport/Qt/QVTKWidget.cxx:50:11: fatal error: QX11Info: No such file or directory

And indeed, the files are actually present, like in your case.

Are you perhaps following this procedure as well, to install Paraview for OS Mesa?:
https://www.paraview.org/Wiki/ParaVi...ew_And_Mesa_3D

I need it to run post processing scripts on a server without screen.
So I too would like to include the header files of QtExtras in the paraview installation. However, I don't have the option to turn on VTK USE X, as I actually need it.

Did you perhaps find a way to solve it using a reference to the header file?


Thanks a lot!

Wouter.
