This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig19310305CB1D4343BC0E2C29 Content-Type: multipart/mixed; boundary="------------070608030709050508060704" This is a multi-part message in MIME format. --------------070608030709050508060704 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Building ports not explicitely enabling USE_GCC=3D4.6+ 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=3Dclang instead of CC=3D/usr/bin/clang CXX=3Dclang++ instead of CXX=3D/usr/bin/clang++ CPP=3Dclang-ccp instead of CPP=3D/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 ## =2Eif !defined(NO_CLANG) =2Eif !defined(CC) || ${CC} =3D=3D "cc" CC=3D /usr/bin/clang =2Eendif =2Eif !defined(CXX) || ${CXX} =3D=3D "c++" CXX=3D /usr/bin/clang++ =2Eendif =2Eif !defined(CPP) || ${CPP} =3D=3D "cpp" CPP=3D /usr/bin/clang-cpp =2Eendif ## Don't die on warnings #NO_WERROR=3D #WERROR=3D ## Don't forget this when using Jails! #NO_FSCHG=3D CFLAGS=3D -O3 -pipe # -fno-strict-aliasing COPTFLAGS=3D -O3 -pipe # #CXXFLAGS+=3D -stdlib=3Dlibc++ =2Eendif My /etc/src.conf is attached. If there is a clean way to distinguish, please help me.
