Yes, but it already passes -std=3Dc++11 in the correct places, as far as = I know. E.g. during the clang and libc++ builds. > It seems to be the problem at > = https://lists.freebsd.org/pipermail/freebsd-toolchain/2015-October/001757.= html > which I've fixed in an upcoming commit to properly pass -std=3Dc++11 = to > the lib32 build in CXXFLAGS. Hm, is this occuring during the build of libcxxrt, or of libc++? If it is the former, then it seems that the system headers don't properly declare _Static_assert() in that case. I have no clue as to why, though maybe it's picking something up from gcc's famously "fixed" standard headers? -Dimitry --Apple-Mail=_305F779C-473E-42BC-9E2D-8B485BF481D0 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.29 iEYEARECAAYFAlb0bbgACgkQsF6jCi4glqPmmgCfa1W4Uouk2F0pWc9e2cIybOPX seQAn1yoe0dAR1YhQamNkMiwcpKoKYnb =N+KF -----END PGP SIGNATURE----- --Apple-Mail=_305F779C-473E-42BC-9E2D-8B485BF481D0--
