During what stage is this, and is it an incremental (e.g. -DNO_CLEAN) build? With this kind of failure, it is usually required to be able to inspect the full buildworld log, and the exact command line you used to invoke make. If you can, upload that somewhere so it can be viewed. That said, it looks like something is messing up your include order, as during a very early stage in buildword, the sys/sys/ headers are symlinked to objdir/tmp/legacy/usr/include/sys/. This should include the mman.h header. -Dimitry --Apple-Mail=_88441850-20A9-4B67-810B-FCAB5251A2DF 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 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCX1z3EwAKCRCwXqMKLiCW o4kBAKDTIf4sZRZ059Y6rWoSF3cGXTrs+ACg/0CKKoPw747cx2xHN3h0TrT+0KI= =po9J -----END PGP SIGNATURE----- --Apple-Mail=_88441850-20A9-4B67-810B-FCAB5251A2DF--
