I notice on 10.2 we're using "FreeBSD clang version 3.4.1". But there are
bugs in this version of clang that I'm having trouble with.
Is compiling a newer (say, 3.7.1) version of clang to target FreeBSD
supported? I have no desire to replace any of the libraries, just the
compiler itself. Is that supposed to work _without_ going through the
ports/pkgs system?
IOW, can I just download from llvm.org the clang+llvm source, compile
it on FreeBSD, and then use it safely?
It should. The ports don't include many patches.
Yeah, I was just looking at the patches we do include. One of them it looks
like causes some of the llvm.org-provided includes to not be installed.
I'm not sure I can, well, not install them because I also need to use the
same install to do cross compiles. A quick check shows that those includes
are used when targetting cross and native.
Am I correct about the include files? And, if so, are there plans to
upstream patches so the llvm.org includes will work out of the box for
FreeBSD-hosted-and-targetted compiles?
I am fairly sure the BSD developers share as much as they can upstream.
You may want to look at current, it now has clang 3.7 and it appears 3.8
is being tested.
