You should use XCC, XCXX and XCPP instead, as described here: https://wiki.freebsd.org/ExternalToolchain You will almost certainly also need: NO_WERROR= to disable fatal errors on buildworld warnings. > It exploded pretty badly: > > http://people.freebsd.org/~sbruno/doingitwrong.txt This particular failure is probably due to the clang-devel port still using libstdc++ by default, and recent versions of head don't have libstdc++ anymore. So add: CXXFLAGS+= -stdlib=libc++ to your src.conf. Last but not least, you can check the status of recent FreeBSD head with trunk clang here (thanks to Pawel Worach for maintaining these bots): http://llvm-amd64.freebsd.your.org:8010/builders/freebsd-clang-amd64 As you can see, there have been quite a few problems lately... -Dimitry
