Error with sqldrivers, qsql_mysql, while building Qt on MacOS
Unsolved
Installation and Deployment

I have been trying to build ParaView to test the Qt custom apps examples here
(https://gitlab.kitware.com/paraview/paraview/tree/master/Examples/CustomApplications)on MacOS, to see if it's possible to build a Qt desktop app that uses the ParaView framework and if everything works buy the Qt license and start building.I have followed the site instructions for the superbuild here
(https://gitlab.kitware.com/paraview/paraview-superbuild)I have had several problems with the Qt build, after some tweaking here is the result
These are the steps I have done:
$ mkdir pv $ cd pv $ git clone https://gitlab.kitware.com/paraview/paraview-superbuild.git $ cd paraview-superbuild $ git fetch origin # ensure you have the latest state from the main repo $ git submodule update $ cd .. $ mkdir paraview_build $ cd paraview_build $ cmake ../paraview-superbuild $ ccmake -DCMAKE_OSX_SDK=macosx10.14 ../paraview-superbuildI enabled the CMake variables:
ENABLE_qt5 ENABLE_python ENABLE_python2Then ran:
$ makeFirst, I got the error
/Users/username/Desktop/dev/pv/paraview_build/superbuild/qt5/src/qtbase/src/platformsupport/fontdatabases/mac/qfontengine_coretext.mm:833:20: error: qualified reference to 'QFixed' is a constructor name rather than a type in this context return QFixed::QFixed(int(CTFontGetUnitsPerEm(ctfont)));Which was solved by going to the file
/Users/username/Desktop/dev/pv/paraview_build/superbuild/qt5/src/qtbase/src/platformsupport/fontdatabases/mac/qfontengine_coretext.mmand remove
QFixed::prefix in line 833After that, I re run make and got a lot more errors

Ho do I solve this?

Hi and welcome to devnet,
What version of Qt is it ?
Why not use a prebuilt version ? -
I'm following your advice and use a prebuild version of Qt.
What do you think I need? Because everything is really heavyHave in mind that I not only need to build paraview with
enable_qt5= onbut later I'm going to useQt Creatorto create my own app that uses the paraview framework
Thanks!

Then go with only the latest LTS currently the 5.12 series.
