clang on OS X
There seems to be significant progress regarding using clang as a pkgrsc
compiler. Using pkgsrc on OS X, that makes my life easier, thanks.
However, I regularily run into some packages not building because of clang
being pickier about possible programming errors (see pkg/48318 for an example),
or other issues, the weirdest one so far being
fatal error: error in backend: Unsupported asm: input constraint with a
matching output constraint of incompatible type!
The clang I'm using is
Apple clang version 1.7 (tags/Apple/clang-77) (based on LLVM 2.9svn)
while pkgsrc contains a 3.3 one.
So two questions on the subject:
1. Does anyone run bulk builds with clang?
If yes, on which platform using which clang version?
2. What's the suggested/supported way using clang/OS X?
Use the clang that comes with Xcode or build clang from pkgsrc?
