New submission from Alexander Kanavin <alex.kana...@gmail.com>: You can see here:
https://github.com/python/cpython/blob/master/Makefile.pre.in#L708 that regen-importlib is building a binary from .o files which are built from .c and .h files, which are, at the same time, regenerated by other regen- targets. This does cause build errors in heavily parallelized builds, we've been seeing it regularly in Yocto Project lately: https://bugzilla.yoctoproject.org/show_bug.cgi?id=12596 I tried to see if I can easily correct target dependencies in the makefile, but couldn't figure it out. So, a workaround, for us, would be to issue 'make regen-importlib' ahead of other things: make regen-importlib make regen-all ---------- components: Build messages: 313894 nosy: Alexander Kanavin priority: normal severity: normal status: open title: regen-importlib is causing build races against other regen-all targets in Makefile.pre.in versions: Python 3.5, Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33080> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
