Qt installation broken after upgrade to Ubuntu 21.04: Unknown modules in Qt: core gui ...
-
Hi, today I did an upgrade to Ubuntu 21.04. After that my project won't compile anymore with the error:
Project ERROR: Unknown module(s) in QT: core gui widgets chartsMy guess was that something has gone wrong with the paths of the libraries. So I checked:
$qmake -query QT_SYSROOT: QT_INSTALL_PREFIX:/usr QT_INSTALL_ARCHDATA:/usr/lib/x86_64-linux-gnu/qt5 QT_INSTALL_DATA:/usr/share/qt5 QT_INSTALL_DOCS:/usr/share/qt5/doc QT_INSTALL_HEADERS:/usr/include/x86_64-linux-gnu/qt5 QT_INSTALL_LIBS:/usr/lib/x86_64-linux-gnu QT_INSTALL_LIBEXECS:/usr/lib/x86_64-linux-gnu/qt5/libexec QT_INSTALL_BINS:/usr/lib/qt5/bin QT_INSTALL_TESTS:/usr/tests QT_INSTALL_PLUGINS:/usr/lib/x86_64-linux-gnu/qt5/plugins QT_INSTALL_IMPORTS:/usr/lib/x86_64-linux-gnu/qt5/imports QT_INSTALL_QML:/usr/lib/x86_64-linux-gnu/qt5/qml QT_INSTALL_TRANSLATIONS:/usr/share/qt5/translations QT_INSTALL_CONFIGURATION:/etc/xdg QT_INSTALL_EXAMPLES:/usr/lib/x86_64-linux-gnu/qt5/examples QT_INSTALL_DEMOS:/usr/lib/x86_64-linux-gnu/qt5/examples QT_HOST_PREFIX:/usr QT_HOST_DATA:/usr/lib/x86_64-linux-gnu/qt5 QT_HOST_BINS:/usr/lib/qt5/bin QT_HOST_LIBS:/usr/lib/x86_64-linux-gnu QMAKE_SPEC:linux-g++ QMAKE_XSPEC:linux-g++ QMAKE_VERSION:3.1 QT_VERSION:5.15.2My guess is that the modules has to be in
