Maybe this = is because the clang binary itself gets built statically (and so will = definitely not be PIE), but the rest of the 'extras', such as bugpoint, = are regular dynamic executables. And note that none of the libraries = built under lib/libclang are built with -fPIC, at the moment. So that = might cause trouble with your PIE patches. In any case, the interesting thing is what the actual linker error was. = Do you have more of the preceding build log, including the rest of the = settings that were used to build world? And also, what does "file = /usr/obj/usr/data/source/git/opBSD/hardenedBSD.git/usr.bin/clang/bugpoint/= .../../../lib/clang/libllvmirreader/libllvmirreader.a" say? -Dimitry --Apple-Mail=_BA330A0E-BAD8-4F4B-A868-F6AA7CD1287E 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 v2.0.22 (Darwin) iEYEARECAAYFAlOCMTMACgkQsF6jCi4glqNQmQCgxsg9UC9JkSn8kNHnariVhESs xa4An2oaJXR9EThhr5gpLZ9LjH907/rQ =kgCZ -----END PGP SIGNATURE----- --Apple-Mail=_BA330A0E-BAD8-4F4B-A868-F6AA7CD1287E--
