Building ports not explicitely enabling USE_GCC=4.6+ are considered using the system's LLVM/CLANG, which is clang 3.2 in our installation (FreeBSD 10.0-CURRENT #0 r240164), but since some ports require the special ports devel/llvm and lang/clang, LLVM 3.1 and clang 3.1 get installed and 3.1 is used instead the system's 3.2 whenever "clang", "clang++" is invoked.
Following the WIKI at http://wiki.freebsd.org/BuildingFreeBSDWithClang introduces the usage of CC=clang instead of CC=/usr/bin/clang CXX=clang++ instead of CXX=/usr/bin/clang++ CPP=clang-ccp instead of CPP=/usr/bin/clang-ccp Is this intended? Since I can not simply change the search patch - I need to have /usr/local/bin before /usr/bin, is there a way to avoid this confusion? Building software with makefiles or self-created ports always refer to the port's LLVM/CLANG, which is LLVM/CLANG 3.1 due to some reuqirements of several ports. I'm really confused. Am I missing some special knob here and fell into this pit by not-having-the-knowledge? Or is it really this messy? Well, I'd like to stay with the core's LLVM/CLANG, which is 3.2 whenever I simply issue "clang" or "clang++" (a pity that LLVM isn't completely installed). My /etc/make.conf portion looks this: ## ## CLANG ## .if !defined(NO_CLANG) .if !defined(CC) || ${CC} == "cc" CC= /usr/bin/clang .endif .if !defined(CXX) || ${CXX} == "c++" CXX= /usr/bin/clang++ .endif .if !defined(CPP) || ${CPP} == "cpp" CPP= /usr/bin/clang-cpp .endif ## Don't die on warnings #NO_WERROR= #WERROR= ## Don't forget this when using Jails! #NO_FSCHG= CFLAGS= -O3 -pipe # -fno-strict-aliasing COPTFLAGS= -O3 -pipe # #CXXFLAGS+= -stdlib=libc++ .endif My /etc/src.conf is attached. If there is a clean way to distinguish, please help me. Regards, Oliver
