-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have committed a patch which fixes Boost.Build for clang-linux. The Boost.Build configuration for clang precompiled headers used a command line invocation of clang which, to my knowledge, has never worked. - -pch-use and -pch-create were the flags used, and no -o flag was placed before the target output file. I cannot find a version of clang that ever supported this syntax. There are three major distributions of clang for Linux; LLVM/Clang itself (source only), RPMs (source and binaries) and .debs (source and binaries). As the existing Boost.Build implementation of PCH support for Clang does not seem to by the clang versions shipped via any of these three mediums, I've junked the old bjam actions entirely and replaced them with actions that work. This fixs Boost.Math for clang on linux (previously clang-linux failed to compile the Boost.Math shared libraries because of this). clang-darwin has been fine because the PCH generators were disabled (I guess whoever did that forgot to do the same for clang-linux). I am not going to move these changes over to the clang-darwin toolset, because I do not have access to a darwin tester. If someone on darwin is willing to test for me, please let me know and I'll provide a patched version of clang-darwin.jam that should provide PCH support. - -- Bryce Lelbach aka wash boost-spirit.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAk1XgFAACgkQ9cB/V3/s9Ez65ACfXxWcm6v5v/P6UXeCcsOmqSXJ uLMAoJHkhxA/4w3CM53ZUDVc8d7rwyI7 =AN6v -----END PGP SIGNATURE-----
