New submission from STINNER Victor <vstin...@python.org>:
When Python is built without --enable-shared, the "Py_FrozenMain" is not exported. When Python is built with --enable-shared, the "Py_FrozenMain" is exported as expected. I can reproduce the issue with attached reproduce.tar.gz example: * build.sh exports "func1" symbol * build_ar.sh doesn't export the "func1" symbol The difference is that build.sh links directly two object files (.o) into a binary, whereas build_ar.sh creates a static library (.a) and then link the static library into a binary. Python is always built with a static library (libpythonVERSION.a) which causes the issue. A solution is to pass -Wl,--whole-archive option to the linker to export *all* symbols exported by all object files, and not only export symbols of the object files which are used. I'm not sure why, but "Py_FrozenMain" is the *only* impacted symbol of the whole C API. This issue was discovered by Petr Viktorin who works on the stable ABI: https://mail.python.org/archives/list/capi-...@python.org/thread/5QLI3NUP3OSGLCCIBAQOTX4GEJQBWJ6F/ ---------- components: C API files: reproduce.tar.gz messages: 393675 nosy: vstinner priority: normal severity: normal status: open title: "Py_FrozenMain" symbol is not exported versions: Python 3.11 Added file: https://bugs.python.org/file50043/reproduce.tar.gz _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44133> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
