Make GTQTC automatically Linux OS.

[Itamar Lins]

Hi!
I'm trying to run an example using GTQTC but without success on Linux.

$ hbmk2 gtqtc.hbp
hbmk2[gtqtc]: plugin: HB_QTPATH, HB_QTSUFFIX not set, could not autodetect
'moc' executable

I put:       export HB_WITH_QT=/usr/include/x86_64-linux-gnu/qt6
And make and make install... 

...

qt6-base-dev is already the newest version (6.9.2+dfsg-1ubuntu1)

Any advice on how to proceed?

Best regards,
Itamar M. Lins Jr.

Hi!

Any fix script gtqtc.hbp
It look for moc-qt6 but the name of file is only moc.

$ pkg -L qt6-base-dev-tools | grep moc
/usr/lib/qt6/libexec/cmake_automoc_parser
/usr/lib/qt6/libexec/moc

hbmk2[gtqtc]: plugin: HB_QTPATH, HB_QTSUFFIX not set, could not autodetect 'moc-qt6' executable

Best regards,

Hi!

With the help of AI and reading here and there, and modifying the hbmk2.prg file to get GCC 15.2.0
I managed to compile.

harbour/contrib/gtqtc$ hbmk2 gtqtc.hbp -cpp=iso17
