SUMMARY Appimage hardcodes QT_PLUGIN_PATH in AppRun, I can't add plugins like IMEs, except unpack and repack the appimage In file AppRun, QT_PLUGIN_PATH is coded this way: 69 export LD_LIBRARY_PATH=$DIR/usr/lib/:$LD_LIBRARY_PATH 70 export QT_PLUGIN_PATH=$DIR/usr/plugins/ 71 export XDG_DATA_DIRS=$DIR/usr/share/:$XDG_DATA_DIRS As a result, my IME, fcitx, doesn't work because it relys on a file located in /usr/lib/x86_64-linux-gnu/qt5/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so The IME problem is easy to solve, since the bundled qt is newer than the system one, I only need to unpack image, copy the file, and repack. I can also solve the IME problem by changing line 70 in AppRun to QT_PLUGIN_PATH=$DIR/usr/plugins:$QT_PLUGIN_PATH, and setting QT_PLUGIN_PATH=/usr/lib/x86_64-linux-gnu/qt5/plugins before running digikam. Yet both require unpacking and repacking. But my question is, is there any specific reason that in AppRun, QT_PLUGIN_PATH is dealt with differently from, e.g., XDG_DATA_DIRS and LD_LIBRARY_PATH ? Can it be ,like, QT_PLUGIN_PATH=$DIR/usr/plugins:$QT_PLUGIN_PATH, so that users can add plugins using QT_PLUGIN_PATH without unpacking and repacking ? SOFTWARE/OS VERSIONS OS: ubuntu 20.04 software: digikam appimage 7.2.0-rc
Hi, Mixing different Qt5 plugins version can make digiKAm unstable. This is why this kind of PATH settings is private in AppImage. The solution is to include the IME Qt plugin officially in embedded version compiled for AppImage. Gilles Caulier
