Description Trond Endrestøl 2021-11-17 11:37:27 UTC

I think the issue in bug #258377 must be revisited.

On today's current, I get this error when building lang/python39:

LD_LIBRARY_PATH=/construction/xports/lang/python39/work/Python-3.9.8 CC='cc -pthread' LDSHARED='cc -pthread -shared  -L/usr/local/lib  -fstack-protector-strong   ' OPT='-DNDEBUG'  _TCLTK_INCLUDES='' _TCLTK_LIBS=''  ./python -E ./setup.py  build

In ${WRKSRC}/build/lib.freebsd-14.0-CURRENT-amd64-3.9, I find the file
_sysconfigdata__freebsd14_x86_64-unknown-freebsd14.0.py, but not a file named
_sysconfigdata__freebsd14_x86_64-unknown-freebsd14.py.

lang/python38 nor lang/python310 exhibit this issue.

Verified by pkg-fallout. Couldn't see anything obvious between the LLVM 13 import to now in base.

See https://bugs.python.org/issue45405 and
https://github.com/python/cpython/commit/9c4766772cda67648184f8ddba546a5fc0167f91

They added a check for Darwin which defeats the regex. We need to adjust it.

lang/python3(6|7|8|9|10): work around unwanted multiarch detection again

Here's another patch, to make the workaround hopefully a bit more robust.

Comment 4 Trond Endrestøl 2021-11-18 07:53:45 UTC

I can confirm the patch works, although I only tried lang/python3{8,9,10}.

Comment 5 Trond Endrestøl 2021-11-26 13:37:30 UTC

(In reply to Trond.Endrestol from comment #4)
lang/python311 needs the same treatment on current as was done for lang/python310.

Unless there is any objection, I will commit this patch later today.

    lang/python3(6|7|8|9|10|11): work around unwanted multiarch detection again

    In ports 6bef09666460 we patched out python's erroneous multiarch
    detection using sed, but upstream changed the surrounding parts in the
    configure script to defeat the regex we were using. Update the regex to
    cope with the change.
