Is this a known issue and I'm just bad at = searching, or is this something I should report (and where?) Bugzilla search is just very bad, so it's not you. :-) This typically turns up for ports on i386 that use -z notext in their linker flags, to work around text relocation issues. See also <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D268495>; and <https://cgit.freebsd.org/ports/commit/?id=3D145ca5487348>. As of lld 15 the linker checks dynamic relocations more strictly, and unfortunately the maintainers turned these "incorrect addend" messages into internal errors instead of warnings (at least when lld is compiled with assertions enabled). Meanwhile, I have been informed that these diagnostics are actually quite harmless, and can be ignored. To suppress them, the linker flags should include --no-check-dynamic-relocations. Similar to audio/openal-soft, this should look something like: .include <bsd.port.pre.mk> .if ${COMPILER_TYPE} =3D=3D "clang" && ${COMPILER_VERSION} >=3D 150 LDFLAGS_i386+=3D -Wl,--no-check-dynamic-relocations .endif # ... other stuff ... .include <bsd.port.post.mk> -Dimitry --Apple-Mail=_364396A8-95A5-4DC8-9AEB-DD6A2A6BAD52 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 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCY/SUvwAKCRCwXqMKLiCW o/vUAKDhgQISrYsnSt8AWM4wyM3QNcOO8QCfSBKVhyOEuoU0DUZ5M5P4N31GMrU= =pqaW -----END PGP SIGNATURE----- --Apple-Mail=_364396A8-95A5-4DC8-9AEB-DD6A2A6BAD52--
