AppImage loads library from system even if present in AppDir

nitanmarcel · September 23, 2022, 5:06pm

I’m trying to build an AppImage from a QT audio player using linuxdeploy linuxdeploy-plugin-qt and linuxdeploy-plugin-gstreamer and I have some issues where playing music throws up an error when loading a gvfs library which is present in the AppDir.

/usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so: undefined symbol: gvfs_get_socket_dir
Failed to load module: /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so

Music plays fine on my os but the error still persists.

The AppImage has been build using the following commands and tools:

./linuxdeploy-x86_64.AppImage --plugin qt --appdir AppDir --desktop-file AppDir/usr/share/applications/com.github.fcrollet.vpsplayer.desktop

./linuxdeploy-x86_64.AppImage --plugin gstreamer --library /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so --appdir AppDir --desktop-file AppDir/usr/share/applications/com.github.fcrollet.vpsplayer.desktop

./appimagetool-x86_64.AppImage AppDir -n

The AppImage has been build on ubuntu:18.04 and it’s running on ubuntu:22.04. Since all of this is done on a github workflow I had to use a docker container that doesn’t have everything in place so first I had to downgrade libsystemd0=237-3ubuntu10.53 libudev1=237-3ubuntu10.53 then install gvfs. Maybe I’m missing something here?

apt install -y qtchooser qt515base qt515declarative qt515multimedia qt515svg qt515x11extras qt515wayland build-essential python3-pip ninja-build wget pkg-config libsamplerate0-dev libsndfile1-dev libfftw3-dev ladspa-sdk lv2-dev vamp-plugin-sdk libboost-test-dev meson ninja-build libssl-dev libgl1-mesa-dev fuse libfuse2 ibgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio gvfs git

The output with QT_DEBUG_PLUGINS=1 is the following

Hello @nitanmarcel. linuxdeploy is not part of the AppImage project, and I don’t think its author reads here. So it’d be best to describe your issue over at Issues · linuxdeploy/linuxdeploy · GitHub. Thanks!

@nitanmarcel I don’t know if this will solve your problem, but you might want to check out some docs on the patchelf command.

I use it in the 0ad appimage build script.

Looks like your libs are getting copied without setting the rpath, so a bit different case than I’m experiencing though.
