py-pyqt5 @5.6: conflict between Python versions

[dliessi (Davide Liessi)]

I tried to install py27-pyqt5 while py35-pyqt5 was active. I got this error during activation:

--->  Activating py27-pyqt5 @5.6_0
Error: org.macports.activate for port py27-pyqt5 returned: Image error: /opt/local/libexec/qt5/plugins/PyQt5/libpyqt5qmlplugin.dylib is being used by the active py35-pyqt5 port.  Please deactivate this port first, or use 'port -f activate py27-pyqt5' to force the activation.

The attached patch fixes the conflict, but might lead to problems at runtime. Can you test this out?

See also #51620.

I would commit this, it's just that I'm unable to test it at the moment (being too lazy to upgrade my OS and having issues with building some of the Qt5 dependencies).

Marko?

I'm sorry I never answered to comment:2, but I haven't yet had the chance to test the change. I'll manage to be near the 10.11 machine tonight and test the patch.

This seems to use a patch to achieve what my own proposal achieves with existing configure arguments. I think that's preferable. I've updated my patch against the current port and am now test-building py27-sip and py35-sip .

There also is a 5.7 upgrade which theoretically should build against Qt 5.6 according to the docs, but appears not to.

I'll update #51620 when I'm done.

This has been fixed with d4bfb294/macports-ports, see also #51620.

Indeed I've been able to install both py27-pyqt5 and py35-pyqt5. Thanks for fixing.
