Qt Web Engine compilation in linux (Ubuntu Desktop 22) [Urgent]
-
Hi everyone and thanks for your time.
I want to display a local html five in a qt web engine view.
I've installed qt this way :
sudo apt-get install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools
then I install qt creator and gcc compiler.
but QT WEB ENGINE is not detected by qt creator or qmake. I get the following error :
Unknown module(s) in QT: webengine
When i compile the same app in windows 10, it works. I noticed that windows10 was using MSVC compiler. When I change the compiler to mingw, web engine is again not found.
So my questions :- does qt web engine is only compiled on MSVC ( microsoft visual studio compiler ) ?
- how to have MSVC in linux then ?
- if not possible, how to compile web engine in a linux environment since it is supported according to the doc : https://doc.qt.io/qt-5/qtwebengine-platform-notes.html#linux
Thank you very much for your answers !

No, it works on other platforms too.

You can't.

Yes, but you don't need to. Just instal it:
sudo apt install libqt5webengine5But the recommended way to get Qt is to use the official installer https://www.qt.io/download

OK thanks for your answer. Indeed, I reinstalled Qt with online installer and now gcc compiler can detect and compile qtwebengine binaries.
Except now my app is a blank screen ( it should render a web view of www.qt.io) and the following error :
/home/axel/Qt/5.15.2/gcc_64/lib/libQt5WebEngineCore.so: .dynsym local symbol at index 3 (>= sh_info of 3)any idea ? thanks !
