See <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248756>. This is because clang 11 defaults to -fno-common now, causing some programs that incorrectly define multiple copies of the same global variables to no longer link. It can be worked around by adding -fcommon to the compilation flags, but in most cases it should not be too difficult to get rid of the multiply defined symbols. > It is unclear to me whether these are actual problems I need to > take care of, or just some kind of screw-up on the package build > server.

Yeah, this warning is seen all the time, and while it sounds very ominous, there is not much you can do about it. -Dimitry --Apple-Mail=_DC73F1F1-794E-4652-AEBB-1F4192D15149 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.2 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCX0EqOwAKCRCwXqMKLiCW o6uCAKCYWiLba100SjC8ob0scrUwp8JC0wCgxIXH42EkKqcuUkv3/q0RLunN/j4= =y6Jp -----END PGP SIGNATURE----- --Apple-Mail=_DC73F1F1-794E-4652-AEBB-1F4192D15149--
