Comment 1 wolthera 2023-07-27 19:10:09 UTC

The problem is "FT_Get_Transform", which means that the appimage is somehow using the wrong version of freetype?????

Comment 2 Alvin Wong 2023-07-30 15:38:14 UTC

It looks like the AppImage does not include the shared objects for freetype, and also harfbuzz and fontconfig. This is be a problem we need to address, because we probably expect to be using some rather recent versions of them.

`FT_Get_Transform` was added in freetype 2.11.0. OpenSUSE still only has 2.10.x according to https://repology.org/project/freetype/versions.

Marking this as a release blocker.

Embed our font libraries into the AppImage

We require quite new font libraries for Krita with experimental features,
so we cannot expect system libraries to be present.

I first tried to use the same fallback approach like we use for
libstdc++, but then remembered that these libraries do not guarantee
backwards compatibility, so we shouldn't try that.
