Caused by getting rid of building via Perl: https://github.com/llvm/llvm-project/commit/88dae3d5d0230747f3cbabdde9ac5ae9e5dc3f8d

Now we need to add a dependency on Python as in the LLVM port.

Make sure not to use a python port that has libomp in its recursive deps. C11 is needed for python 3.11 and later which means a clang dependency on older systems.

clang ports depend on libomp; with libomp broken, ports that need a newer clang can't build either.

Ugh. This is going to get ugly, isn’t it. We can just revert back to previous version for now? Thoughts?

comment:5 Changed 4 weeks ago by jmroot (Joshua Root)

Use python310 for now? We might end up needing some new bootstrap port somewhere to break the cycle.

Resolution: fixed
Status: assignedclosed

In 745ec6b54b020e8feacdeec212b224d89c852660/macports-ports (master):

libomp: add python310 build dep

Also restrict perl5 dep to older version.

Fixes: #71149

worth considering: no clang actually needs libomp as a dep

Thank you! On my list to get to today, but you beat me to it.

Certainly worth considering. Ports/variants that need it can always say so, and it would minimize the fallout from any future issues to those ports that actually need it.
