Then the linker finds the archive malformed. John Baldwin added some special handling for libraries under lib/clang, so they emit smaller debug information, so just leave out -g from your CFLAGS, buildworld will automatically take care of applying the right -g flags in all the various places. -Dimitry --Apple-Mail=_106C2E11-3C8A-4B8C-A057-C94C46140F1D 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 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCWom1FgAKCRCwXqMKLiCW o5gLAKCH4U8h/cdH8qWoWeYJgKswIe/GdgCeKwBMlFY/vQMTQI40QIn/GNiW630= =dQmj -----END PGP SIGNATURE----- --Apple-Mail=_106C2E11-3C8A-4B8C-A057-C94C46140F1D--
