Hello!
I have successfully built Paraview v5.6.0 (cmake -G “Visual Studio 15 2017 Win64” -DCMAKE\_BUILD\_TYPE=Release -DPARAVIEW\_BUILD\_QT\_GUI=ON …\ParaView-v5.6.0) , then built it using visual studio 2017 (Release, x64). Then used this command “windeployqt.exe paraview.exe” because for some reason qt could not find some dependencies.
Then I was trying to build plugins from ParaView examples but I have the same errors with almost all plugins.
My actions:
- copy paraview/Examples/Plugins/DockWidget to another directory (C:\PARAVIEW2\build2\MyPlugins\DockWidget)
- create directory (C:\PARAVIEW2\build2\MyPlugins\build-DockWidget)
- cd C:\PARAVIEW2\build2\MyPlugins\build-DockWidget
- (cmake …\DockWidget -G “Visual Studio 15 2017 Win64” -DBUILD\_SHARED\_LIBS=ON -DCMAKE\_PREFIX\_PATH=“C:\PARAVIEW2\build2”)\>log.txt
[log.txt](https://1drv.ms/t/s!Avr-7fhsIv2K2nRTVknW6Cv5WWak)
It gives warning:
> CMake Warning at C:/PARAVIEW2/ParaView-v5.6.0/CMake/ParaViewQt.cmake:83 (message):
> Qt ‘5.6.0’ found and will be used. Note, however, that the officially

In summary configuring gives warning that it will use Qt 5.6 but officially supported version is 5.9, despite the fact I have in environmental variables path to Qt 5.9 and built my ParaView using Qt 5.9.
During building it gives error “Unresolved external symbols”
How can I solve this errors?
I have tried to build PV with examples directly, it also gives errors.
Thank you in advance.

After I have added two dependencies (vtkRenderingFreeType-pv5.6.lib;vtkInteractionStyle-pv5.6.lib;) from (C:\PARAVIEW2\build2\lib\Release;), the plugin was built successfully.
