The problem with the ports implementation of WITH_DEBUG is that it always disables all optimizations, without a possibility to override. Which bloats the resulting object files, libraries and executables, and especially so for large C++ projects such as LLVM. I can recommend the following workaround. If you want to build a port with optimizations disabled, you can always pass -O0 in CFLAGS. -Dimitry Index: Mk/bsd.port.mk =================================================================== --- Mk/bsd.port.mk (revision 436685) +++ Mk/bsd.port.mk (working copy) _at__at_ -1646,7 +1646,7 _at__at_ MAKE_ENV+= DONTSTRIP=yes STRIP_CMD= ${TRUE} .endif DEBUG_FLAGS?= -g -CFLAGS:= ${CFLAGS:N-O*:N-fno-strict*} ${DEBUG_FLAGS} +CFLAGS:= ${CFLAGS} ${DEBUG_FLAGS} .if defined(INSTALL_TARGET) INSTALL_TARGET:= ${INSTALL_TARGET:S/^install-strip$/install/g} .endif
