configure:2482: checking for C compiler default output file name
configure:2485: gcc -isysroot /Developer/SDKs/MacOSX10.3.9.sdk -
Wl,-
syslibroot,/Developer/SDKs/MacOSX10.3.9.sdk conftest.c >&5
/usr/bin/ld: -syslibroot: multiply specified
collect2: ld returned 1 exit status
So I gather that gcc does not like those parameters, which I
confirmed
with my own little foo.c test file.
Are you using GCC 4.0?
powerpc-apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple Computer, Inc.
build 5226)
From Xcode 2.2pr2.
Try not setting LDFLAGS. Passing -isysroot to gcc might cause it to
pass -isyslibroot to the linker if you're using gcc to link.
Well, if I do that, everything builds, but how can I be sure that it
actually used the 10.3.9 SDK?
Add "-v" to your CFLAGS and, at least with my version of gcc (a bit
later than the one in Xcode 2.2 DP 2, but I don't think we've changed
this in the interim), you'd see that if you use gcc to link and pass -
isysroot it invokes ld with -syslibroot.
I'm pretty sure it's doing that in your case because if it didn't do
that you wouldn't be getting the error you're seeing. :)
Shows using both CFLAGS and LDFLAGS as previously discussed in this
thread, so it seems that is the right way, and yet I get that "-
syslibroot: multiply specified" error when I try... what gives?
Sounds like we should change the technote to clarify that you should
only set LDFLAGS to include -syslibroot if your makefile doesn't pass
CFLAGS for linking. Your makefile apparently does use CFLAGS while
linking.
You may also want to file a bug report asking ld to not warn when -
syslibroot is specified multiple times if it's always set to the same
value.
