Undefined symbol Error encountered while running runSofa

[GrisNuAge]

Hi everyone! Glad to be here in the new forum!
I am trying to build sofa using ubuntu22.04 version.
When compiling with ninja, I changed the #include QWebEngineView code in moc_QDocBrowser.cpp and QDocBrowser.h to #include <QtWebEngineWidgets/qwebengineview.h>, thereby avoiding compilation errors.
After compiling, when I run ./bin/runSofa, I encountered the following error:

[ERROR]   [PluginManager] Plugin loading failed (/home/iven/sofa/build/lib/libSofa.GUI.Qt.so): /home/iven/sofa/build/lib/libSofa.GUI.Qt.so: undefined symbol: _ZN14QWebEnginePage16staticMetaObjectE

All the output is as follows：

I don't know how to fix this error, so I come here to ask for help. Thank you in advance for your help.

Did you install Qt Charts and Qt WebEngine when you installed Qt? See https://www.sofa-framework.org/community/doc/getting-started/build/linux/#core-required

Otherwise, as a workaround, you can disable the DocBrowser in CMake: uncheck the variable SOFA_GUI_QT_ENABLE_QDOCBROWSER

[GrisNuAge]

Yes, I installed Qt charts and Qt WebEngine. I will try your workaround. Thank you!

[alxbilger]

What version of Qt did you install?

[GrisNuAge]

Qt 5.13.2
