It seems like multimedia/shotcut should depend on multimedia/mlt-qt5 rather than multimedia/mlt. [which of course does nothing to fix the conflict] Shotcut doesn't require mlt-qt5, but fails with mlt-qt4 (as well as Kdenlive fails with mlt-qt5). A solution might be dropping mlt-qt4 completely, and making Kdenlive rely on MLT GTK+ module to replace mlt-qt4 functionality. I'll look into it. Anyway, kdenlive-kf5 will solve the issue as soon as it comes to the ports. # pkg delete -yf multimedia/mlt-qt4 # mv /usr/local/lib/qt4 /usr/local/lib/qt4_ # portmaster multimedia/mlt-qt5 # portmaster multimedia/shotcut $ shotcut // shotcut run without coredumps. # mv /usr/local/lib/qt4_ /usr/local/lib/qt4 $ shotcut [Debug ] <static ShotcutSettings &ShotcutSettings::singleton()> language "ru_RU" [Debug ] <static ShotcutSettings &ShotcutSettings::singleton()> deinterlacer "onefield" [Debug ] <static ShotcutSettings &ShotcutSettings::singleton()> external monitor "" [Debug ] <static ShotcutSettings &ShotcutSettings::singleton()> GPU processing false [Debug ] <static ShotcutSettings &ShotcutSettings::singleton()> interpolation "nearest" [Debug ] <static ShotcutSettings &ShotcutSettings::singleton()> video mode "" [Debug ] <static ShotcutSettings &ShotcutSettings::singleton()> realtime true [Info ] <Application::Application(int &, char **)> Starting Shotcut version 17.02.01 [Info ] <Application::Application(int &, char **)> Linux version [Info ] <Application::Application(int &, char **)> number of logical cores = 2 [Info ] <Application::Application(int &, char **)> locale = QLocale(Russian, Cyrillic, Russia) [Info ] <Application::Application(int &, char **)> install dir = "/usr/local/bin" [Info ] <Application::Application(int &, char **)> device pixel ratio = 1 [Debug ] <MainWindow::changeTheme> begin [Debug ] <MainWindow::changeTheme> end [Debug ] <MainWindow::MainWindow()> begin [Info ] <GLTestWidget::GLTestWidget(QWidget *)> OpenGL context version 2 0 [Debug ] <Mlt::Controller::Controller()> begin Segmentation fault (стек памяти сброшен на диск) $ gdb /usr/local/bin/shotcut shotcut.core GNU gdb 6.1.1 [FreeBSD] … (gdb) bt #0 0x0000000805dca338 in realloc () from /lib/libc.so.7 #1 0x0000000805dca85e in free () from /lib/libc.so.7 #2 0x000000081fb7b1aa in QTest::compare_string_helper () from /usr/local/lib/qt4/libQtTest.so.4 #3 0x0000000805e42e22 in __cxa_finalize () from /lib/libc.so.7 #4 0x000000081fb76b34 in ??

It seems qt4 and qt5 are conflicting but it only seems to affect Shotcut. Removing qt4 (or more specifically qt4-testlib) will allow Shotcut to run without core dump but qt4 apps (such as kdegames) won't anymore. ldd reveals that Shotcut is correctly linked to qt5 libraries. qtchooser says it is set to qt5. I attempted to use QT_SELECT without success. I also changed some code to remove some qt4 references (CMake, library check macro). A little experiment removing qt4-testlib and symlink with qt5 equivalent works for qt4 apps but Shotcut still core dump (while trying to load qt4 libs). This issue has been opened for few months now. Any updates? It's not very realistic to have to uninstall completely qt4. Filed an issue on Shotcut github. Perhaps Shotcut people might be able to point us in the right direction. https://github.com/mltframework/shotcut/issues/450 I might have found a solution based on feedback from mlt/shotcut people. It's fairly simple, just make sure opencv is disabled in graphics/frei0r-plugins and deinstall of graphics/frei0r-plugins-opencv. That's it. Andrew (daeron@) reported that the fix doesn't work when Kdenlive is installed. Investigating the issue down to mlt-qt4 interfering with Shotcut and Shotcut qt5 libraries (i.e. frei0r-plugin, etc) interfering with Kdenlive. https://bugzilla.novell.com/show_bug.cgi?id=931815 They suggest to build Kdenlive with proper mlt/qt libraries. So Kdenlive should have an option to be built with mlt-qt5 instead of mlt-qt4. Alberto? The fix I suggested otherwise works when Kdenlive is not installed. Most other qt4 apps should be able to coexist with Shotcut. Maintainer reset. mlt-qt4 will be removed soon -- so we can close this one as overcome by events. |
multimedia/shotcut 17.02 coredumps possible with installed multimedia/mlt-qt4, but require multimedia/mlt (with qt5?). But I can't install multimedia/mlt-qt5: mlt-qt5-6.4.1 conflicts with installed package(s): mlt-qt4-6.4.1 They install files into the same place. You may want to stop build with Ctrl + C. And multimedia/mlt-qt4 required by multimedia/kdenlive.
