So I will need to make that __FreeBSD_version dependent. I have fixed this particular problem, new patch is here: http://www.andric.com/freebsd/clang/head-r260112-clang34-2.diff.xz SHA256 (head-r260112-clang34-2.diff.xz) = 4c602b42e890f82cbf5f7ee4aecb91a77ce3dcaacc01c210953e1cdd29d1ac21 This will only use execinfo.h and backtrace() for the world stage of the build, when the libraries that supply them have already been built. With this diff, I have successfully built head on 9.2-STABLE with gcc as the base compiler. I will also test it on 10.0-RC4, but I foresee no problems there. -Dimitry [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.22 (Darwin) iEYEARECAAYFAlLF2+sACgkQsF6jCi4glqNyEwCaA6HqGXAwrZgDldkVGsYSgLdv JC8AnjhVkAdsNJ4rUFf6b5Z3wOdIu4L/ =RDyI -----END PGP SIGNATURE-----
