QtWebEngine

@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.

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.

@Chakra2811 Since this is a PyQt question, if you do not get an answer here you could try asking the PyQt folks over at https://riverbankcomputing.com/mailman/listinfo/pyqt

still think the components that are used in examples should be included by default or at least if nothing else warned that you wont be able to do some examples unless you have them (in the right places mind you, not tucked away in some weird documentation). It would also be nice if there is gonna be typing completion in qmake, cmake, etc., that it actually be contextual to the syntax of those items and not just spit out seemingly random tags most of which don't have anything to do with said files... even better, maybe include at least the headers that way you know for sure you are missing the library instead of ghostin' the whole kit'n'kaboodle.

@therealmatiss Qt 6.8 does not support Ubuntu 18.04 (see https://doc.qt.io/qt-6/linux.html). Use an older Qt version which supports this Ubuntu version (which does not get any support anymore by the way).

Thanks. Created one https://bugreports.qt.io/browse/QTWB-77

thx for your reply

First upgrade to a recent version. If the error still persists, create a minimal, compilable example. And if it then still exists it might be a bug in Qt not yet fixed.

@gfxx The OS is Windows 11 22H2

@Haowei-Hsu you saved my day ^^. Thank you. Qt Positioning really fix this issue on my Qt 6.8

GGnome provided the solution to this problem in this thread. Setting the following in my main.cpp before initialising the app cured all performance issues with my WebEngineView: QQuickWindow::setGraphicsApi(QSGRendererInterface::OpenGL);
