Ports That Redefine CC / CPP / CXX
Some ports hardcode which version they want by redefining the CC and/or CPP and/or CXX Makevars. In PR 229626 MarkLinimon claims that this is a bad implementation, and that the values instead should be passed via environment variables. However, that PR as yet has not received any attention.
The problem is that each of these ports generates extra output lines at the end of any bulk poudriere run on any GCC-based arch (see more complete list below). Example from a powerpc64 build:
/bin/sh: clang60: not found make[2]: "/usr/ports/Mk/Uses/compiler.mk" line 78: warning: "clang60 --version" returned non-zero status make[2]: "/usr/ports/Mk/Uses/compiler.mk" line 133: warning: "clang++60 -### /dev/null 2>&1" returned non-zero status
This is annoying. The usage ought to be discouraged.
Even if the port correctly parameterizes the version, this is still not the correct way to do things.
Wrong:
CC= ${LOCALBASE}/bin/clang${LLVM_VER}
CXX= ${LOCALBASE}/bin/clang++${LLVM_VER}
Correct (certain ports):
CONFIGURE_ENV+= CC=${LOCALBASE}/bin/clang${LLVM_VER} \
CXX=${LOCALBASE}/bin/clang++${LLVM_VER} \
LLVM_CONFIG=${LOCALBASE}/bin/llvm-config${LLVM_VER}
Correct (gmake-based ports):
MAKE_ENV+= CC=${LOCALBASE}/bin/clang${LLVM_VER} \
CXX=${LOCALBASE}/bin/clang++${LLVM_VER} \
LLVM_CONFIG=${LOCALBASE}/bin/llvm-config${LLVM_VER}
Correct (cmake-based ports):
CMAKE_ARGS= -DLLVM_CONFIG_EXECUTABLE:PATH=${LOCALBASE}/bin/llvm-config${LLVM_VER} \
TODO some ports ignore the passed parameters. These ports are multiply broken and must be fixed.
