QtWebEngine

How can I build WebEngine and PDF manually? Could you please guide me? I am working on this for the first time.

Seems to be the same topic like: https://forum.qt.io/topic/156752/qt6-7-compile-failed-from-source-in-windows11/3

If I comment below lines in component which is handling Webengine and browser related logic, the issue is not observed.

QWebEngineProfile *m_profile;
m_profile- >clearHttpCache();

Any idea if we need to change above to logic in QT5.15.11 for better handling. As currently it seems call is hang/stuck if i keep it.

Thank you, it seems to be the case. Do you happen to know how to set this attribute in QML? I need to modify part of extension (plasmoid) for KDE Plasma, it uses QML to setup the WebView.

@Mallikarjuna said in QT Webengine bitbake do_compile error for QT6.8.1:

../../../../../git/src/3rdparty/chromium/third_party/distributed_point_functions/code/dpf/internal/evaluate_prg_hwy.cc:152:14: internal compiler error: in eliminate_stmt, at tree-ssa-sccvn.cc:6870

You get an internal compiler error when compiling Chromium.
You could try to get newer compiler or build different Chromium version.

I am doing the same thing with custom cache and storage folders. but I think it's not working as expected. for example if I open stackoverflow and set the permission to accept all cookies, then reopen my browser and again go to stackoverflow, it again asks for my permission. which should not happen if it is storing my permissions.

@ZhangL , what additional libraries did you install? i ran into same error
thanks!

@cobook Then call configure with --help parameter to see how the verbose parameter is called now.

@CDQT said in QtWebEngineProcess.exe not found.:

yes. files exists. checked the environment with cmd command "echo %QTWEBENGINEPROCESS_PATH%"

That does not tell us whether a file exists, it just shows the value of an environment variable. Something like dir %QTWEBENGINEPROCESS_PATH% would be better than echo.

The error when you run QtWebEngineProcess from the command line was to be expected, I was just trying to find out whether it would be found and run.

Have you checked whether QTWEBENGINEPROCESS_PATH is recognised/handled in a Qt version as old as 5.9? I don't know. Maybe find what doc page https://doc.qt.io/qt-5/qtwebengine-deploying.html#deploying-qt-webengine-processes read at 5.9? You might also try Googling QtWebEngineProcess.exe not found and look through the various hits to see whether any of them might be applicable to your situation.

I changed the OS to ubuntu and solved this problem. But still have a problem to play DRM contents in QtWebEngine. I'll make new issue

UPDATE: After blowing up Maya 2025 by doing a pip update on mayapy for Pyside6 and all of it's subcomponents (don't do that), I communicated with the X_ITE developers. They were able to release a version of X_ITE for me that removed the ECMAScript 2023 functions, and now uses javascript that is compatible with Chrome 108 and the version of PySide6/Qt6 compatible with QWebEngine in Maya 2025.

@Ferdinand-Castelino In the screen shots you show libraries, not packages.
How to add dev package depends on how you created the sysroot and what Linux distribution is running on your device. On Ubuntu this package is named "libnss3-dev". Dev packages contain header files and what else is needed to build software which uses a library, it is not enough to install the library itself.
