Description Ben Beasley 2025-03-08 15:58:00 UTC
In F43/Rawhide, blender FTBFS, and crashes on startup (error loading libyaml-cpp.so.0.8).

Reproducible: Always

Steps to Reproduce:
1. mock -r fedora-rawhide-x86_64 --clean
2. mock -r fedora-rawhide-x86_64 -i blender
3. mock -r fedora-rawhide-x86_64 --chroot 'blender --help'
Actual Results:  
$ blender --help

blender: error while loading shared libraries: libyaml-cpp.so.0.8: cannot open shared object file: No such file or directory

Expected Results:  
$ blender --help
Blender 4.3.2
Usage: blender [args ...] [file] [args ...]
[…]

The package also FTBFS. From https://koschei.fedoraproject.org/build/19982984:
