texmaker compilation (CentOS Stream release 8)

 After system update, the old compiled texmaker refuses start: 

texmaker: /lib64/libQt5Core.so.5: version `Qt_5.15.2_PRIVATE_API' not found (required by texmaker)

Compiled Fedora rpm versions (35, 36) do not work as well.

Simple recompilation of texmaker-5.0.4 fails due to old qt5 version (QT>=5.7 is necessary).

Thus:

dnf install qt6-qtbase-devel
dnf install qt6-qt5compat-devel

error: Unknown module(s) in QT: qml

dnf install qt6-qtbase-private-devel

(still errors: missing  qabstractitemmodel_p.h , see )

dnf install qt6-qtdeclarative-devel

wget https://www.xm1math.net/texmaker/texmaker-5.1.3.tar.bz2
tar xjf texmaker-5.1.3.tar.bz2 && cd texmaker-5.1.3

qmake6
make -j 6

make install
