QTwebkit Build failed on QT-5.15 via Yocto

[Chenxi Mao]

Hi QT experts:

I would like to integrate the QTwebkit to QT5.15 via Yocto project, unfortunately, I got build error till now.
QTwebkit has been build successfully on QT-5.13.

1. On QT-5.15, I've move the QT webkit sha1 as below:
   https://codereview.qt-project.org/c/yocto/meta-qt5/+/296402
2. On meta-qt5 5.15 branch, there is another build issue has been fixed as below:
   diff --git a/recipes-qt/qt5/qtdeclarative_git.bb b/recipes-qt/qt5/qtdeclarative_git.bb

+SRCREV = "1a2ab822fa24733f83d6720d2af8498ecbd5cbda"

Howerver, during webkit link, there is a problem as below

/usr/include/QtCore/qbytearray.h:530: undefined reference to `QWebFullScreenVideoHandler::qt_metacall(QMetaObject::Call, int, void**)'

I found the root cause is the moc didn't create "moc_qwebfullscreenvideohandler.cxx" on 5.15
There is only a parameter file created.

Another clue is in build/Source/WebKit/CMakeFiles/WebKit_autogen.dir/AutogenInfo.json, the qwebfullscreenvideohandler.h in in MOC_SKIP section, I not sure whethere this cause the moc_qwebfullscreenvideohandler.cxx cannot be created.

I would like to know which code create WebKit_autogen.dir/AutogenInfo.json file and how to remove qwebfullscreenvideohandler.h from the MOC_SKIP section.

Do I need to revert some commits in moc or there are solutions to fix this build error?

Thanks in advance.

This choice of SRCREV is horribly wrong. Please use 444bd2bda5fa46c2b4b99adaf6e9b2074b03a0d1

Hi expert:
I saw you suggest to switch to 5.212 branch.
Do i need to extra modification in meta-qt5?
E.g; remove python3 suppot patch?

Thanks

Why would you want to do that?

Ah, you had a local patch. I wonder why nobody even tries to contact maintainer when doing such work. What a horrible waste of time for everyone.
