Description Mikolaj Izdebski 2022-05-07 15:52:06 UTC

Description of problem:
ghc9.4-base package provides libffi.so.8()(64bit) virtual package, so in can be installed instead of proper libffi as a dependency of many packages, including low-level system packages.
That can break the whole operating system, including DNF and other basic system utilities.

Version-Release number of selected component (if applicable):
ghc9.4-9.4.0.20220501-1.fc37

Reproducible in Koji build - they fail to load libffi.so.8
ImportError: libffi.so.8: cannot open shared object file: No such file or directory
Example: https://koji.fedoraproject.org/koji/taskinfo?taskID=86776860
Corresponding Koschei build: https://koschei.fedoraproject.org/build/12813323

Also reproducible in MBI CI: https://mbi-artifacts.s3.eu-central-1.amazonaws.com/a270f095-0c79-4775-a4c4-790178457031/result.html

I've untagged this package for now from f37 tag.

Comment 2 Jens Petersen 2022-05-09 04:48:12 UTC

Thanks - sorry about that! :(

I will continue to work with upstream to get the support for using system libffi working again
with the newer GHC buildsystem.

Comment 3 Miro Hrončok 2022-05-09 06:12:07 UTC

In the meantime, let's filter the libffi.so.8()(64bit) provides out?

Comment 4 Jens Petersen 2022-05-11 03:31:43 UTC

Ah thanks Miro 👍 - that idea had crossed my mind too, but I didn't look into it.

Anyway this was already fixed upstream now thankfully and I backported it to ghc9.4 already.
Also I plan to backport it to ghc9.2 later, though that might be slightly harder perhaps -
anyway it is on an older different libffi soname so it is less problematic.
