New submission from Michael Felt <aixto...@felt.demon.nl>:
Currently, on AIX, whenever the -j option is passed to make there are many WARNINGS from the loader (ld) re: duplicate symbols. While it is not possible to eliminate these warnings completely - as some are not related to the Python build, but external (3rd party) packaging - MOST of these warnings can be eliminated by ensuring that the export file creation completes before additional steps try to use it. By adding a small test to see if the export file is in the process of being made - and waiting for that to finish - the messages "go away". The PR that is being proposed only affects AIX (a script named makeaix_exp). The script has not been modified in 22 years - so I guess the -j option is something that showed up after 1998 :) I know it is not perfect - but removes a tremendous amount of noise - most of the time. Michael p.s. requesting backport to 3.8 so all buildbots benefit. ---------- components: Build messages: 367541 nosy: Michael.Felt priority: normal severity: normal status: open title: AIX: parallel build and ld WARNINGS type: behavior versions: Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40424> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
