I've just removed them and it worked. Or is there a reason for rpath to
system lib directory?
What about other keys? I've also encountered -fwhole-program and
-malign-double
What I plan to do is:
---
USES+= compiler:env
.include <bsd.port.pre.mk>
post-patch:
.if ${COMPILER_TYPE} == "clang"
@${REINPLACE_CMD} -e 's|-fwhole-program||' ${WRKSRC}/CMakeLists.txt
.endif
---
but what if next version of clang learns of this key? I'd like to have
something like
.if ! ${COMPILER_SUPPORTED_ARGUMENTS:M-fwhole-program}
@${REINPLACE_CMD} -e 's|-fwhole-program||' ${WRKSRC}/CMakeLists.txt
.endif
.if ${COMPILER_SUPPORTED_ARGUMENTS:M-malign-double}
CXXFLAGS+= -malign-double
.endif
