I have this in /etc/make.conf: .include "/etc/make.clang.conf" and /etc/make.clang.conf itself: .if !defined(CC) || ${CC} == "cc" CC=clang .endif .if !defined(CXX) || ${CXX} == "c++" CXX=clang++ .endif .if !defined(CPP) || ${CPP} == "cpp" CPP=clang -E .endif # Don't die on warnings NO_WERROR= WERROR= # Don't forget this when using Jails! NO_FSCHG= This is from http://wiki.freebsd.org/BuildingFreeBSDWithClang which talks about building the FreeBSD kernel & base, but it's also used by the Ports system. Another option is to set CC & CXX explicitly: cd /usr/ports/*/foobar make CC=clang CXX=clang++ > FWIW I'm trying to build libreoffice with clang as it doesn't build, or > more accurately doesn't build and test correctly.

Worth a shot anyway :) I've never tried building LibreOffice at all, let alone with Clang, but apparently it can be done: http://nabble.documentfoundation.org/libreoffice-clang-success-td3788899.html Regards Andrew
