Done with the help of https://github.com/Mindavi/nixpkgs-mark-broken
Tool is still WIP but this is one of the first results.
I manually audited the results and removed some results that were not valid.
Note that some of these packages maybe should have more constrained platforms set
instead of broken set, but I think not being perfectly correct is better than
just keep trying to build all these things and never succeeding.
Some observations:
- Some darwin builds require XCode tools
- aarch64-linux builds sometimes suffer from using gcc9
- gcc9 is getting older and misses some new libraries/features
- Sometimes tools try to do system detection or expect some explicit settings for
platforms that are not x86_64-linux
I am not sure if we still need the old packages, nothing explicitly
depends on polyml56 or polyml57 according to a grep, not sure if
external packages might (hol and isabelle depend on polyml, the latest
version).
New libffi doesn't have FFI_SYSV for x86/64 unix, this pulls in the
commit for the upstream version which fixes it, and ports that patch to
the 5.7 version. The 5.6 version is unchanged.
For ZHF: #80379
