As best I know, Qt recommends just using the class rather than prefixing the containing module (QtCore). The official Qt examples are all coded this way. If nothing else the documentation of the QTimer class says Header: #include <QTimer> Nothing has changed recently in Qt about the way includes are expected to be done. You should have had -I/opt/qt5/include/QtCore in the compilation command. That should have come from the Cflags in Qt5Core.pc. That should have been tested by gst-plugins-base-1.18.1/tests/examples/gl/meson.build at line 4. Maybe that is a fruitful path to investigate what is wrong with your setup. My configure looks like Run-time dependency qt5 (modules: Core) found: YES 5.15.1 (pkg-config) Run-time dependency qt5 (modules: Core, Gui, Widgets) found: YES 5.15.1 (pkg-config) Run-time dependency qt5 (modules: OpenGL) found: YES 5.15.1 (pkg-config) and I do not get the failure that you get. -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
