I took a quick look, but I don't think there is any quick solution. For some reason, clang 3.4.1 (which shipped with 10.4) cannot handle the static_asserts which are inside the piece of code in question. Also, there are several other compilation errors, due to it being unable or unwilling to cast pointers. Upstream LLVM has recently bumped the requirements for building quite aggressively, it could very well be that a higher version of clang or gcc is now required to build 8.0, precisely because of the above. At some point they apparently wanted to drop the workarounds for old compilers. -Dimitry --Apple-Mail=_B81FEC47-5AEF-421C-B561-A266BF2BC3A1 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.2 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCXSQtGgAKCRCwXqMKLiCW o++2AKCtZdv3eTQx03W6apAzxpmtHxL65ACfWoyl6SYWjBIK8DNSDUr5TdZoGoo= =bK3L -----END PGP SIGNATURE----- --Apple-Mail=_B81FEC47-5AEF-421C-B561-A266BF2BC3A1--
