QtWebEngine

I also got this error when using debian11 with Qt5.15.2 /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 3 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 4 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 5 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 6 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 7 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 8 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 9 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 10 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 11 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 12 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 13 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 14 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 15 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 16 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 17 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 18 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 19 (>= sh_info of 3) /usr/bin/ld: /home/eton/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so.5.15.2: .dynsym local symbol at index 20 (>= sh_info of 3)

@gouneken No, Linux ( Fedora 35 )

@gouneken said in how to enable using QWebEngineWidgets module after downloading?: I'm using a module from another version of qt or something else You, of course, have to install it for Qt version you're using

The Solution is : QWebEngineProfile *profile = new QWebEngineProfile(QString::fromLatin1("MyApplication.%1").arg(qWebEngineChromiumVersion())); // unique profile store per qtwbengine version QWebEnginePage *page = new QWebEnginePage(profile); // page using profile QWebEngineView *view = new QWebEngineView(); view->setPage(page); view->setUrl(AccueilUrl); view->setZoomFactor(1.2); setCentralWidget(view);

this is still problem in qt5.15.2 . has not been fixed completely.

@gouneken multiple inheritance of QObject isn't possible (Page_all class) your Page_all class inherits QWebEnginePage and also has a QWebEnginePage as a member variable?! dont name variables the same as their type names! the createWindow() method is intended to create a new physical window (a QWidget for example) and return the containing QWebEnginePage. You might need to create another QWebEngineView inside (or a use it directly as a window)

Hello, When I try to recompile QtWebEngine with the proprietary codecs I have an error : C:\Qt\5.15.2\Src\qtwebengine>"C:\Qt\5.15.2\msvc2019_64\bin\qmake.exe" -- -webengine-proprietary-codecs Running configuration tests...

@raven-worx After testing, for my case, it is mainly caused by the frame rate of the cocos2d-js web page. The default frame rate is 60. I changed it to 30 for either canvas or webgl render mode. The usages of CPU and GPU dropped significantly.

Issue is resolved. I had updated my GPU drivers and after restart, it began to work.

@Nlakhani I don't have any further knowledge of Mac. Works fine for me elsewhere.

@jack-reemoon sorry because you use gRPC instead of rest service? Thanks
