MacPorts also provides an llvm-gcc-4.2 port; I was able to use this to build
OpenJDK 7u45 with minimal headache.
The only gotcha was Accelerate.framework's reliance on the 'immintrin.h'
header. This is a top-level compiler-shipped header that imports subheaders for
the intrinsics supported by the current target; it's shipped with clang and
more modern versions of GCC, but not with llvm-gcc-4.2.
I worked around this by providing a header search path containing a copy of
modern GCC's immintrin.h:
http://trac.macports.org/browser/users/landonf/openjdk7/dports/java/openjdk7/files/clang-compat-headers?rev=114871
The full build configuration can be found in my openjdk7 Portfile; it's not too
hard to read, even if you're unfamiliar with MacPorts:
http://trac.macports.org/browser/users/landonf/openjdk7/dports/java/openjdk7/Portfile?rev=114871
I'll be merging jtreg, openjdk7, and, if I have time, openjdk8 ports over to
MacPorts trunk in the not-too-distant future.
Cheers,
Landon
