AppImage: libthai.so.0: cannot open shared object file: No such file or directory

[Yanestra]

Apparently, there is a lib missing in the file kiwix-desktop_x86_64_2.3.1-4.appimage

[kelson42]

@Yanestra Which version of linux Distribution do you use?

[Yanestra]

The magic of AppImages is that locally installed libs shouldn't matter at all as long as the platform matches. If I have to install libthai locally, the whole AppImage thing is pointless.

I can answer Gentoo x86_64 current, if that helps but I bet it doesn't.

linuxdeployqt (the tool used for creating an appimage) considers libthai.so a core library and excludes it from being added to the appimage.

libthai.so is explicitly "blacklisted" in https://raw.githubusercontent.com/probonopd/AppImages/master/excludelist (since that is a dynamic link to the HEAD of the master branch, here is the permalink to a fixed revision of that file):

libthai.so.0
# Workaround for:
# audacity: /tmp/.mount_AudaciUsFbON/usr/lib/libthai.so.0: version `LIBTHAI_0.1.25' not found (required by /usr/lib64/libpango-1.0.so.0)
# on openSUSE Tumbleweed

[kelson42]

@veloman-yunkan Thx for the analysis.... but not how the solution should look like!?

[veloman-yunkan]

@kelson42 My tentative solution is to include libthai.so in the appimage. Yet, I am not sure that it won't result in the opposite problem (because of which libthai.so was "blacklisted" in the linuxdeployqt project).

[Korne127]

Jfyi, libthai has been removed from the excludelist with AppImageCommunity/pkg2appimage#555 so this workaround shouldn't be necessary anymore after linuxdeploy has been updated.

[kelson42]

@veloman-yunkan Does that mean we should rollback our fix?

[Korne127]

As a new version of linuxdeploy has been released, the fix shouldn't be necessary anymore (assuming you'll use the newest version).

[veloman-yunkan]

@veloman-yunkan Does that mean we should rollback our fix?

We can to it when linuxdeployqt incorporating the said change is released.

As a new version of linuxdeploy has been released ...

No, as of now the continuous build of linuxdeployqt (that our build system uses) has been released twenty days ago:

$ ./linuxdeployqt --version
linuxdeployqt  (commit 8cb9438), build 67 built on 2024-07-09 18:22:04 UTC

[Korne127]

Ah, I'm sorry, I think I confused two projects. linuxdeployqt is no longer actively maintained, but if you make an issue, maybe they'll release a new version nevertheless.

Closing in favour of #1165
