[Distutils] Re: manylinux1 guidelines for zlib?

Updating on this. It seems the manylinux1 tooling may automatically link and bundle an old zlib version if you link dynamically against it. That can be counter-productive... Regards Antoine. -- Distutils-SIG mailing list -- distutils-sig@python.org To unsubscribe send an email to distutils-sig-
