In my case, it was Poudriere (running = on 14-CURRENT) trying to build a 13-STABLE jail. The Poudriere jail's = "src.conf" was taken from the actual system for which Poudriere builds = packages. It had (amongst others) these two options: >=20 > WITH_SYSTEM_COMPILER=3Dyes > WITHOUT_CROSS_COMPILER=3Dyes >=20 >=20 > When I commented these out in the jail-src.conf Poudriere file the = jail built correctly. >=20 > I figure the system built fine because its system compiler is LLVM = 14.x. The Poudriere system compiler is LLVM 15.x, which has the = breaking change wrt. old-style prototypes. Yes, that is what I suspected in Oliver's case: if you skip the cross-tools stage in a buildworld of stable/13 on a 14-CURRENT host, by setting WITH_SYSTEM_COMPILER, you are bound to run into compilation errors that have been fixed in 14-CURRENT, but not yet MFC'd. The safest solution is to let cross-tools do its thing, which will check the host compiler, and automatically build an appropriate version of the compiler and linker for the stable branch, if required. That said, I will be merging clang 15.0.7 and a bunch of other things that should solve all these errors to stable/13 at some point, but not before the 13.2-RELEASE is out. This is to avoid making life more difficult for our release engineering team. -Dimitry --Apple-Mail=_C4B76800-750C-4437-B591-C769C537FFF4 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/0yvQAKCRCwXqMKLiCW o2u/AJ4ku5kfQDoBxldq8vtZ0JPIewxJKwCfaHkCzxLC53ZHTXfB6fI1CwFOyKg= =BqFr -----END PGP SIGNATURE----- --Apple-Mail=_C4B76800-750C-4437-B591-C769C537FFF4--
