py38-pyqt5: error: object of type 'QSGGeometry' cannot be assigned because its copy assignment operator is implicitly deleted

"Command execution failed". The latter part of the log file reads:

I am attempting to install "treeline". This is the first time I have used MacPorts.

MacPorts v. 2.6.2; OS Mojave 10.14.6.

In the future, please fill in the Port field with the port that fails to build

[mf2k (Frank Schima)]

Please attach the main.log file after cleaning the port (sudo port clean py38-pyqt5) and re-open the ticket. Without this log, we cannot diagnose the problem.

Replying to mf2k:

Thanks for the guidance. I've cleaned, attempted to install again, and attach the main.log file, zipped as its 1.0Mb. Hope I've done this right.

The issue here is that the new py-sip isn't compatible with this py-pyqt5. There is an updated py-pyqt5 that I'd guess is compatible; it claims to add compatibility with the current Qt 5.15.0 release. Here's a link to the announcement with download info: ​https://riverbankcomputing.com/news/PyQt_v5.15.0_Released .

[michaelld (Michael Dickens)]

Or it might be that PyQt5 now requires its own SIP module; here's that announcement: ​https://riverbankcomputing.com/news/PyQt5-sip_v12.8.0_Released

[reneeotten (Renee Otten)]

I can look into updating the py-pyqt5 port, but in the past we typically would hold off until the qt5 is updated.

[michaelld (Michael Dickens)]

I believe PyQt5 is backward compatible, so updating it now should be safe both for current Qt5 as well as the new Qt 5.15.

[mf2k (Frank Schima)]

@michaelld: Can you please update this soon? This port currently cannot be installed at all. Otherwise I think we need to revert py-sip.

[reneeotten (Renee Otten)]

Replying to mf2k:

@michaelld: Can you please update this soon? This port currently cannot be installed at all. Otherwise I think we need to revert py-sip.

I will take a look at it now and put up a PR if it works. But please note that this port is openmaintainer so if you want something to be done quickly, you can always do it yourself.

[reneeotten (Renee Otten)]

so, just a simple update of the versions does allow me to build py38-pyqt5, py38-pyqt5-chart but not py38-pyqt5-webengine.

The latter fails with:

QtWebEngineWidgets/sipQtWebEngineWidgetsQWebEngineCertificateError.cpp:372:99: error: no member named 'CertificateKnownInterceptionBlocked' in 'QWebEngineCertificateError'

which is because QWebEngineCertificateError::CertificateKnownInterceptionBlocked is ​added in Qt 5.15.0.

So this will require an update of the Qt5 port first, before we can update py-pyqt5 and its subports.

[mf2k (Frank Schima)]

@reneeotten: Thank you for looking into this. It's not clear to me what needs to happen now. Hopefully michaelld and MarcusCalhoun-Lopez can figure it out!

[reneeotten (Renee Otten)]

the mailinglist suggest there is a patch to fix building of the latest PyQtWebengine with Qt 5.14.x - I'll try the patch and see if that indeed works.

[reneeotten (Renee Otten)]

In 7fa9969863632abbcc242635ac9cec0bb48a864b/macports-ports (master):

py-pyqt5-[webengine|chart]: update to 5.15.0

• refresh patches
• add patch to allow building of QtWebEngine with Qt 5.14

Closes: #60627

[dajare (David)]

OP here. Even after a "clean" and then re-install, I got an error on py38-pyqt5. So I "uninstall[ed] installed" as a 2.4.1 of the MacPorts guide, and tried again. And ... success! Thanks so much for attending to this bug so swiftly and successfully.

Linking this with Ticket 62009, comment3: I'm having issues with py37-pyqt5 on OSX 10.10.5. Does the fix reference in comment19 here apply to pre-py39-pyqt5 (which my Macports is the most recent and default installation when py-pyqt5 is requested). Mahalo.
