Have you read http://wiki.freebsd.org/BuildingFreeBSDWithClang, which suggests to put: .if !defined(CC) || ${CC} == "cc" CC=clang .endif .if !defined(CXX) || ${CXX} == "c++" CXX=clang++ .endif # Don't die on warnings NO_WERROR= WERROR= in your /etc/src.conf (or make.conf, depending on your preference)? If you use that, it should work, at least for the build32 stage of buildworld on amd64. This workaround is only needed on amd64, not for i386.
