On page 37 of https://conf.kde.org/system/attachments/94/original/TimotheeGiet-GCompris-Akademy2017.pdf it says

Help creating an appimage

[probonopd]

Started work at https://github.com/probonopd/GCompris-qt/blob/patch-1/.travis.yml
Build log at https://travis-ci.org/probonopd/GCompris-qt

[probonopd]

Is a GitHub push -> Travis CI -> GitHub Releases workflow acceptable?

[probonopd]

Still running into compilation issues, https://travis-ci.org/probonopd/GCompris-qt/builds/. Any help appreciated.

[probonopd]

Update: Compilation is working now, AppImage gets built.

Build log:
https://travis-ci.org/probonopd/GCompris-qt

Remaining issue:
plugins/imageformats/libqsvg.so does not get deployed, caused by probonopd/linuxdeployqt#82.

[probonopd]

Applying a workaround, https://transfer.sh/azDIU/GCompris-git.1f109eb-x86_64.AppImage is available for testing now. Seems to be working on openSUSE LEAP 42.2.

Hi,
I have some issue with gstreamer on a fresh ubuntu install: Inconsistency detected by ld.so: dl-tls.c: 74: _dl_next_tls_modid: Assertion `result <= GL(dl_tls_max_dtv_idx) + 1' failed!

Thanks @petitlapin, interesting. Seems to be glibc related. More investigation is needed. Don't remember having seen this before.

Seems to have to do with

External plugin loader failed. This most likely means that the plugin loader helper binary was not found or could not be run. You might need to set the GST_PLUGIN_SCANNER environment variable if your setup is unusual. This should normally not be required though.

According to https://bbs.archlinux.org/viewtopic.php?id=8626,

This is a bug in glibc NPTL and gets triggered by libs that use TLS (Thread local storage) and load a lib via dlopen() calls that fail with unresolved symbols or library dependencies.

So we need to find the cause of the GStremer issues and fix them.

Hi,

sorry for delay.

I tested it on my daily machine with archlinux and on a KaOS virtual machine. The application runs but there are no sound:
(GCompris-git.1f109eb-x86_64.AppImage:2337): GStreamer-CRITICAL **: gst_element_add_pad: assertion 'GST_IS_PAD (pad)' failed
(GCompris-git.1f109eb-x86_64.AppImage:2337): GStreamer-CRITICAL **: gst_object_unref: assertion 'object != NULL' failed
Also the translations are not built and shipped, to have them we need to add a few steps in the install:

• cmake .. -DCMAKE_INSTALL_PREFIX=/usr
• make getSvnTranslations
• cmake .. -DCMAKE_INSTALL_PREFIX=/usr (it needs to be run again so cmake knows about translations, we haven't found a solution to not having to not run cmake again)
• make BuildTranslations
• make -j$(nproc)
  ... (as before)

[probonopd]

Thanks @petitlapin. Could you send a Pull Request please?

[probonopd]

So possibly we need to bundle a private copy of gstreamer and its plugins. This may be some work.

I've send a MR on invent that adds a recipe for building GCompris AppImages using appimage-builder.

AppImage for testing: https://invent.kde.org/alexislo/gcompris/-/jobs/65555/artifacts/raw/build/GCompris--x86_64.AppImage (expires in one week)
