QT plugins directories not copied to VisIt install plugins directory

[griffin28]

Describe the bug

I did a make install -j 2 after building VisIt and when I tried to run VisIt, I received an error Qt: Warning: Could not find the Qt platform plugin "xcb" in "" . I did an export QT_DEBUG_PLUGINS=1 to get more information and discovered the QFactoryLoader was looking specifically in the VisIt install plugins directory (and I believe 1 or 2 others) for the xcb stuff. Once I copied the directories in the QT plugins directory to the VisIt plugins directory that was created after doing the make install everything worked.

I don't remember this being an issue with earlier VisIt releases. I checked an old VisIt install and don't see anything QT related in the plugins directory.

TP library build command:

build_visit --build-mode Debug --makeflags -j16 --no-thirdparty --no-visit --cmake --python --vtk --qt --qwt --boost --mpich --adios --adios2 --advio --boxlib --cfitsio --conduit --gdal --h5part --hdf5 --cgns --netcdf --mfem --silo --szip --icet --zlib --xdmf --tbb --thirdparty-path /home/kgriffin/VisIt/third_party/3.3.0

VisIt build command:

cmake -DCMAKE_BUILD_TYPE=Debug -DVISIT_INSTALL_THIRD_PARTY=ON -DVISIT_BUILD_ALL_PLUGINS=ON -DCMAKE_INSTALL_PREFIX=/usr/local/visit ../src

Desktop

• OS and version: Ubuntu 20.04.5
• VisIt Version: 3.3.0 and 3.3.1

Additional Info: The QT plugins directories (platforms and xcbglintegrations) get copied to linux-x86_64/lib/qtplugins during make install. The QFactoryLoader is expecting them in linux-x86_64/plugins.

@griffin28 what it the contents of qt.conf in linux-x86_64/bin?

[griffin28]

Here's what's in the qt.conf file:

[Paths]
Plugins=../lib/qtplugins

I think the issue is on my end. This was working correctly in 3.1.4 the same setup for QT. Not sure what got messed up.

Another thing to check would be any environment variables related to QT.
