Hello Sandro, or anyone else affected, Accepted qt-gstreamer into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/qt- gstreamer/1.2.0-5ubuntu0.1 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-focal. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Package changed: qtcreator (Ubuntu) => qt-gstreamer (Ubuntu) ** Changed in: qt-gstreamer (Ubuntu Focal) Status: In Progress => Fix Committed ** Changed in: qt-gstreamer (Ubuntu Jammy) Status: In Progress => Fix Committed -- You received this bug notification because you are a member of Ubuntu SDK bug tracking, which is subscribed to qtcreator in Ubuntu. https://bugs.launchpad.net/bugs/1950959 Title: [SRU] Missing dependency in libqt5gstreamer-dev Status in qt-gstreamer package in Ubuntu: Fix Released Status in qt-gstreamer source package in Focal: Fix Committed Status in qt-gstreamer source package in Jammy: Fix Committed Status in qt-gstreamer package in Debian: Fix Released Bug description: [ Impact ] The package libqt5gstreamer-dev is mostly unusable for users whose development environment uses pkg-config to find dependencies. If we use pkg-config to find the CFLAGS that are needed to link with libQt5GStreamer-1.0.so then that will fail. An example command: # pkg-config --cflags Qt5GStreamer-1.0 Package gobject-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `gobject-2.0.pc' to the PKG_CONFIG_PATH environment variable Package 'gobject-2.0', required by 'Qt5GLib-2.0', not found [ Test Plan ] * Execute the command "pkg-config --cflags Qt5GStreamer-1.0" and cofirm that pkg-config can find the CFLAGS needed to link with libQt5GStreamer-1.0.so [ Where problems could occur ] * The dependency fix alone should not cause any problem as its not changing any part of the code. But another fix from Debian had to be added, as without that fix the package is failing to build in Jammy. And, this patch is removing a volatile qualifier from a variable. But this patch is in Debian since Sept, 2022 without any report of regression so I will assume there is little chance of regression on adding it here in Jammy. * Apart from the dependency fix, another patch had to be added for Focal as it was failing to build. This patch is in Debian since Feb,2021 with no report of regression and has also been applied upstream, there is little chance of regression from this patch. [ Other Info ] * the package mentioned in the bug is wrong, it affects qt-gstreamer source. * as mentioned above an extra Debian patch is needed. Without that patch the build fails in Jammy with the error: /<<PKGBUILDDIR>>/elements/gstqtvideosink/gstqwidgetvideosink.cpp: In static member function ‘static GType GstQWidgetVideoSink::get_type()’: /usr/include/glib-2.0/glib/gatomic.h:113:19: error: argument 2 of ‘__atomic_load’ must not be a pointer to a ‘volatile’ type 113 | __atomic_load (gapg_temp_atomic, &gapg_temp_newval, __ATOMIC_SEQ_CST); \ | ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/glib-2.0/glib/gthread.h:260:7: note: in expansion of macro ‘g_atomic_pointer_get’ 260 | (!g_atomic_pointer_get (location) && \ | ^~~~~~~~~~~~~~~~~~~~ /<<PKGBUILDDIR>>/elements/gstqtvideosink/gstqtvideosinkplugin.h:31:13: note: in expansion of macro ‘g_once_init_enter’ 31 | if (g_once_init_enter(&gonce_data)) { \ | ^~~~~~~~~~~~~~~~~ /<<PKGBUILDDIR>>/elements/gstqtvideosink/gstqtvideosinkplugin.h:56:5: note: in expansion of macro ‘DEFINE_TYPE_FULL’ 56 | DEFINE_TYPE_FULL(cpp_type, #cpp_type "_qt5", parent_type, Q_UNUSED) | ^~~~~~~~~~~~~~~~ /<<PKGBUILDDIR>>/elements/gstqtvideosink/gstqwidgetvideosink.cpp:22:1: note: in expansion of macro ‘DEFINE_TYPE’ 22 | DEFINE_TYPE(GstQWidgetVideoSink, GST_TYPE_QT_VIDEO_SINK_BASE) | ^~~~~~~~~~~ make[4]: *** [elements/gstqtvideosink/CMakeFiles/gstqt5videosink.dir/build.make:227: elements/gstqtvideosink/CMakeFiles/gstqt5videosink.dir/gstqwidgetvideosink.cpp.o] Error 1 * The package failed to build in Focal also and a Debian patch had to be added for that. * The problem has been fixed in Debian with qt-gstreamer_1.2.0-5.2, so Lunar, Mantic and Noble are not affected. Only Jammy and Focal are affected. [ Original Bug Description ] After installing libqt5gstreamer-dev, the following command fails: pkg-config --exists Qt5GStreamer-1.0 || echo "Failed" Failed more info: pkg-config --cflags Qt5GStreamer-1.0 Package gstreamer-1.0 was not found in the pkg-config search path.
