[odb-users] QT config

[Alex B]

ok here is what i got:

admin at gentoo ~/QTProjects/odb-qt $ odb -I/usr/include/qt5 --std c++11
--profile qt -d sqlite \
--generate-query property.h
In file included from /usr/include/qt5/QtCore/qchar.h:43,

                 from <odb-prologue-2>:1:

admin at gentoo ~/QTProjects/odb-qt $ odb -I/usr/include/qt5 -fPIC --std c++11
--profile qt -d sqlite --generate-query property.h
unknown option '-f'
admin at gentoo ~/QTProjects/odb-qt $

so i found your answer here:
https://odb-users.codesynthesis.narkive.com/dSmA1FfR/problem-compiling-with-qt
and tried, but still get the same error:

admin at gentoo ~/QTProjects/odb-qt $ odb -I/usr/include/qt5 -x -fPIC --std
c++11 --profile qt -d sqlite --generate-query property.h
property.h:4:10: fatal error: QString: No such file or directory
    4 | #include <QString>
      |          ^~~~~~~~~
compilation terminated.
admin at gentoo ~/QTProjects/odb-qt $
admin at gentoo ~/QTProjects/odb-qt $ odb  -x -fPIC -I/usr/include/qt5 --std
c++11 --profile qt -d sqlite --generate-query property.h
property.h:4:10: fatal error: QString: No such file or directory
    4 | #include <QString>
      |          ^~~~~~~~~
compilation terminated.

seems like it still should be added soomewhere in the odb makefile like
suggested here:
