Bug 563898 – dev-python/PyQt5-5.5 fails to build: PyQt-gpl-5.5-python3_4/QtWebKitWidgets/sipQtWebKitWidgetsQWebHitTestResult.cpp:553:42: error: ‘const class QWebHitTestResult’ has no member named ‘linkTitleString’

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Scott Alfter 2015-10-23 18:01:09 UTC]

While rebuilding as part of an "emerge -uND world" invocation, PyQt5 failed with the error in the summary.

Reproducible: Always

This doesn't make any sense... the method is there... no #ifdef's, nothing...

Try without ccache please.

[Comment 5 Paul Jewell 2015-10-24 18:59:42 UTC]

I have also come across this problem. Also, it is re-installing PyQt5-5.5 having previously successfully compiled it. I am not using ccache. I'll post the relevant attachments shortly.

[Comment 8 Scott Alfter 2015-10-24 19:07:11 UTC]

Tried "sudo FEATURES= emerge -1 PyQt5" just now...still failed.  Trying again with FEATURES commented out of /etc/portage/make.conf.

The weird thing is that this is a recompile.  PyQt5 is currently installed (which means it was able to compile in the past), but something (recompile of a dependency?) triggered a rebuild of PyQt5, and now it doesn't want to rebuild.  On another box, it recompiled yesterday without issue.  I tried rebuilding it on this box with the same set of USE flags yesterday, and it still failed.

[Comment 9 Scott Alfter 2015-10-24 19:09:49 UTC]

Commented out the FEATURES line in /etc/portage/make.conf to disable ccache...still failed to compile.

[Comment 11 Davide Pesavento (RETIRED) 2015-10-24 19:44:46 UTC]

Could be related to the qt upgrade. Did you recently upgrade from 5.4.2 to 5.5.1? Check your emerge.log please.

[Comment 12 Paul Jewell 2015-10-24 20:01:05 UTC]

Upgrade to qt 5.5.1 was carried out on 19/10:

  Fri Jun  5 22:39:59 2015 >>> dev-qt/qtcore-5.4.1
  Sat Jun 20 08:50:48 2015 >>> dev-qt/qtcore-5.4.2
  Mon Oct 19 07:27:30 2015 >>> dev-qt/qtcore-5.5.1

PyQt5.5 was previously installed on 28th August:

  Sun Feb 22 14:29:46 2015 >>> dev-python/PyQt5-5.4
  Fri Aug 28 21:45:59 2015 >>> dev-python/PyQt5-5.5

So successful installation had previously occurred under version of qt.

Does sip-4.17 change anything? (I expect not)

wait, this is qtcore... what about qtwebkit? I suspect you still have 5.4.2

[Comment 15 Paul Jewell 2015-10-24 21:38:50 UTC]

You're right - qtwebkit is still at 5.4.2. I am currently upgrading sip to 4.17, and if that doesn't change anything, I'll give upgrade qtwebkit to 5.5.1 and try again.

[Comment 16 Davide Pesavento (RETIRED) 2015-10-24 21:47:02 UTC]

Then I'm sure the reason is the misalignment between qtcore and qtwebkit versions.

QWebHitTestResult::linkTitleString was added in 5.5. There is a conditional in the .sip file, but I guess it looks at the version of qtcore, assuming that all qt modules are at the same version.

[Comment 17 Paul Jewell 2015-10-25 07:28:40 UTC]

Good morning David. I can confirm that with qtwebkit at 5.5.1, the package emerges successfully.

Thanks for identifying the issue - I am going to review how Qt5 here if keyworded to avoid other potential issues of this nature.

[Comment 18 Scott Alfter 2015-10-25 17:25:20 UTC]

Something recently prompted an upgrade of Qt 5 from stable to testing, so the following were added to /etc/portage/package.accept_keywords after something similar to "emerge -auND --backtrack=50 world"

dev-qt/qtxml:5 ~*
dev-qt/qtcore:5 ~*
dev-qt/qtgui:5 ~* 
dev-qt/qtsql:5 ~*
dev-qt/qtdbus:5 ~*
dev-qt/qtconcurrent:5 ~*
dev-qt/qtnetwork:5 ~*   
dev-qt/qtwidgets:5 ~*
dev-qt/qtopengl:5 ~* 
dev-qt/qttest:5 ~*    
dev-qt/qtprintsupport:5 ~*

qtwebkit wasn't included among them.  I'm adding it now, upgrading, and then rebuilding PyQt5.  If this ends up fixing it (and it sounds like it might), that would suggest that there's a missing or outdated dependency somewhere.

[Comment 19 Scott Alfter 2015-10-25 18:36:18 UTC]

qtwebkit built OK, but PyQt5 still won't.  Output from "equery list qt\* | grep 5.4" shows the following:

dev-qt/qtdeclarative-5.4.2-r1
dev-qt/qtmultimedia-5.4.2-r1
dev-qt/qtquick1-5.4.2
dev-qt/qtquickcontrols-5.4.2
dev-qt/qtscript-5.4.2
dev-qt/qtsvg-5.4.2
dev-qt/qtxmlpatterns-5.4.2

Probably need to add those to /etc/portage/package.accept_keywords and try again...

[Comment 20 Scott Alfter 2015-10-25 19:27:51 UTC]

After the last few changes, PyQt5 has finally rebuilt without error.  If qtcore:5 is set ~KEYWORD, all qt*:5 packages need to be set the same way.  In my case, I ended up with the following...YMMV, depending on what other packages you have installed:

dev-qt/qtxml:5 ~*
dev-qt/qtcore:5 ~*
dev-qt/qtgui:5 ~*
dev-qt/qtsql:5 ~*
dev-qt/qtdbus:5 ~*
dev-qt/qtconcurrent:5 ~*
dev-qt/qtnetwork:5 ~*
dev-qt/qtwidgets:5 ~*
dev-qt/qtopengl:5 ~*
dev-qt/qttest:5 ~*
dev-qt/qtprintsupport:5 ~*
dev-qt/qtwebkit:5 ~*
dev-qt/qtdeclarative:5 ~*
dev-qt/qtmultimedia:5 ~*
dev-qt/qtquick1:5 ~*
dev-qt/qtquickcontrols:5 ~*
dev-qt/qtscript:5 ~*
dev-qt/qtsvg:5 ~*
dev-qt/qtxmlpatterns:5 ~*

Most packages are revbumped now to prevent this from happening in the future.
