gqrx requires Qt5 and it is defined in the portfile [1]. Have you changed something that you are trying to build with Qt6?

Hi, Both environments are installed, qt5 and qt6 Now I uninstalled all the qt6 environment and relaunched the gqrx installation:

$ sudo port install gqrx +experimental +iqba

This time the installation worked, gqrx being built without problems. Any idea why it interfered with qt6 even though it only depends on qt5? Thank you.

[ra1nb0w]

Ok. thank you for the test. I got the issue. It uses the default moc and probably installing both Qt this will be renominated in moc5 or something and can managed with port select. Can you verify which /usr/local/bin/moc is available? This seems a qt5 portgroup issue. thank you

[YesNo801]

Hi,

I check for moc

$ ls -al /usr/local/bin/moc ls: /usr/local/bin/moc: No such file or directory

$ sudo port content qt5-qtbase | grep moc

/opt/local/libexec/qt5/bin/moc

After installing qt6: $ sudo port content qt6-qtbase | grep moc

/opt/local/libexec/qt6/bin/cmake_automoc_parser /opt/local/libexec/qt6/bin/moc

Thank you

ops. my fault. Seems that Portgroup qt5 doesn't catch the right moc.

ryandesign: what do you think? an issue for qt5? thanks
