So add: CXXFLAGS+= -stdlib=libc++ to your src.conf. Last but not least, you can check the status of recent FreeBSD head with trunk clang here (thanks to Pawel Worach for maintaining these bots): http://llvm-amd64.freebsd.your.org:8010/builders/freebsd-clang-amd64 As you can see, there have been quite a few problems lately... -Dimitry --Apple-Mail=_5B1D6E0B-971D-475F-811E-D408BF133284 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 v2.0.20 (Darwin) iEYEARECAAYFAlI8tFgACgkQsF6jCi4glqOMlgCg65iNhj0IrRLQkELh3LHxqnJz uV0AoMZxeKFEh1B0RB8lsX9wdai5hMDY =778W -----END PGP SIGNATURE----- --Apple-Mail=_5B1D6E0B-971D-475F-811E-D408BF133284--
