When I talked to Chris Lattner about shared libraries, his advice was that under no circumstances should we consider supporting any C++ APIs =66rom the base system. We can link tools in the system with them and we can provide supportable C API wrappers as Apple does, but any port that links against a libclang.so or libLLVM.so is doomed to break so ports should link against port versions so they can be updated as needed. -- Brooks --NY6JkbSqL3W9mApi Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) iD8DBQFQEWHnXY6L6fI4GtQRAjn8AKDMSMHPgImpcmwE7toZsk2DONQMVACfSt4G gofC1BxsVUvw6yQnkoqhhAA= =rze4 -----END PGP SIGNATURE----- --NY6JkbSqL3W9mApi--
