No version works yet as far as I know. (There has been some recent work on this in llvm but some of it has not been put in the FreeBSD clang/clang++ 3.9.0 experiment so far.) (I sometimes experiment with clang/clang++ on powerpc and analyze the problems and submit reports of the ones that I find.) powerpc64 and powerpc also do not have prebuilt packages, not even just one for pkg itself. This makes getting both a C/C++ compiler set and pkg in place a bit of a mess even for a cross-built bootstrap: A) pkg on the target needs to be built by a C/C++ compiler toolchain. B) /usr/ports/base/gcc usage for getting a compiler toolchain on the target works by putting a .txz file in place for use via pkg add <THAT-FILE> . === Mark Millard markmi at dsl-only.nethelp
