Bundling gtk in AppImage causes errors in some distros.

We are creating AppImage for rustdesk, which can greatly improve the user experience using it. We use appimage-builder to create the AppImage and follow the instructions on offical website of appimage-builder. However, the AppImage can only run successfully in a part of distros. I highly doubt there is some issue when bundling gtk in AppImage, causing critical errors with different version of X11.

Build Env: Ubuntu 18.04 Tested: Ubuntu 18.04(works), Ubuntu 20.04(works), Kubuntu 22.04(works), Manjaro 21.2.6(some works, some is not working, causing gnutls 3_6 not symbol found), Fedora 36 workstation(GNOME wayland) (not working, core dumped).

The AppImageBuilder.yml is here. I use gdb on Fedora 36 workstation to trace the issue, the backtrace is shown below:

Is it OK to bundle the whole of libgtk-3-0 in AppImage(it’s added by appimage-builder --generate automatically)? This package brings lots of dependencies(like gnutls, libglib-2.0), which causes conflict with some systems.

libnsl is part of glibc on Ubuntu based systems but Fedora people move it into another package therefore is not present in the system when the AppImage runs. A solution would be to move libnsl.so.1 from opt/libc to /lib/x86_64-linux-gnu/libnsl.so.1 (you can use a cp command for this in the after bundle, if you use the include file it will also put it in opt/libc).

We should implement this solutions as part of appimage-builder soon.

I think it’s also worth noticing https://github.com/rustdesk/rustdesk/issues/577#issuecomment-1151399825
