Description
This is A MacOS-specific issue. Qt 5.12.3 is affected, but most likely older versions as well.
Steps to reproduce:
- Install Qt via Homebrew
- Build and deploy "Simple Browser" (WebEngineWidgets) example
- /usr/local/opt/qt/bin/qmake
- make
- /usr/local/opt/qt/bin/macdeployqt simplebrowser.app/
- Uninstall Qt
- Run deployed "Simple Browser": simplebrowser.app/Contents/MacOS/simplebrowser
What happens:
It doesn't work, only prints:
dyld: Library not loaded: /usr/local/Cellar/qt/5.12.3/lib/QtGui.framework/Versions/5/QtGui Referenced from: /Users/skale/Projekty/qt-simplebrowser/simplebrowser.app/Contents/Frameworks/QtWebEngineCore.framework/Helpers/QtWebEngineProcess.app/Contents/MacOS/QtWebEngineProcess Reason: image not found dyld: Library not loaded: /usr/local/Cellar/qt/5.12.3/lib/QtGui.framework/Versions/5/QtGui Referenced from: /Users/skale/Projekty/qt-simplebrowser/simplebrowser.app/Contents/Frameworks/QtWebEngineCore.framework/Helpers/QtWebEngineProcess.app/Contents/MacOS/QtWebEngineProcess Reason: image not found
Why it happens:
As it can be seen on listings below, install paths in QtWebEngineProcess.app, which is embedded in simplebrowser.app, all point to locations where these libs used to be on a development machine (/usr/local/Cellar/qt/5.12.3/lib). In the result, the deployed application does not work except for the computer which it was deployed on.
Running `otool -L` on various executables and dylibs prints following:

What doesn't help
Unfortunately, following workaround presented in QTBUG-41611 does not help. Error does not change.
/usr/local/opt/qt/bin/macdeployqt simplebrowser.app/ -executable=simplebrowser.app/Contents/MacOS/simplebrowser
Possible root cause
This may help finding a root cause — Qt distribution available in Homebrew has been configured with following options:
-verbose -prefix #{prefix} -release -opensource -confirm-license -system-zlib -qt-libpng -qt-libjpeg -qt-freetype -qt-pcre -nomake examples -nomake tests -no-rpath -pkg-config -dbus-runtime -proprietary-codecs
Notably -no-rpath option is present, they have valid reasons for that.
