I search if C extensions of the Python standard libraries are always linked or not to libpython... it's complicated. I tested _ctypes, _hashlib and _struct modules: * Debian and Ubuntu: NOT linked to libpython * Conda: LINKED to libpython * Mageia 7: LINKED to libpython * Fedora 28, RHEL 7: LINKED to libpython on Python 2.7 and 3.6, except _struct which is NOT linked to libpython on Python 2.7 It means that using dlopen("libpython2.7.so.1.0", RTLD_LOCAL | RTLD_NOW) may or may not work depending on the Linux distribution and depending on the imported C extensions... If we use the example of Fedora: some C extensions are compiled using Makefile (the Fedora package modifies Modules/Setup, as I showed previously), but others are compiled by setup.py. For example, _ctypes and _hashlib are compiled by setup.py. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34814> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
