Hi,
Sorry for my lated homework. Attached is a proposal of
patch for Mac OS X 10.6. The patch itself is not easy
to read. The patched script would be like following.
It scans all token in CFLAGS, lookup -isysroot, -arch,
-m32 and -m64. If they are not included in LDFLAGS
(for -isysroot and -arch, arguments are also checked),
they are copied to LDFLAGS.
# Some options handling SDKs/archs in CFLAGS should be copied
# to LDFLAGS. Apple TechNote 2137 recommends to include these
# options in CFLAGS but not in LDFLAGS.
set dummy ${CFLAGS}
i=1
while test $i -lt $#
do
c=$1
case "${c}" in
-isysroot|-arch) # options taking 1 argument
a=$2
AC_MSG_CHECKING([whether CFLAGS and LDFLAGS share ${c} ${a}])
if expr " ${LDFLAGS} " : ".* ${c} *${a}.*" > /dev/null
then
AC_MSG_RESULT([yes])
else
AC_MSG_RESULT([no, copy to LDFLAGS])
LDFLAGS="${LDFLAGS} ${c} ${a}"
fi
shift 1
;;
-m32|-m64) # options taking no argument
AC_MSG_RESULT([whether CFLAGS and LDFLAGS share ${c}])
if expr " ${LDFLAGS} " : ".* ${c} *${a}.*" > /dev/null
then
AC_MSG_RESULT([yes])
else
AC_MSG_RESULT([no, copy to LDFLAGS])
LDFLAGS="${LDFLAGS} ${c}"
fi
;;
# *)
# AC_MSG_RESULT([${c} is not copied to LDFLAGS])
# ;;
esac
shift 1
done
At present, I didn't restrict this hook to specific
system. If it's better to restrict this hook to Mac OS X,
please let me know. I'm not sure if there is special
requirement to use different "-arch XXX" or "-m32/-m64"
options between CFLAGS & LDFLAGS.
Sean, could you review the patch? Yet I don't have access
to Mac OS X 10.6 machines, so I cannot check if this patch
solves the problem you reported.
