...tionality has been subsumed into libSystem.dylib on SnowLeopard (darwin10). The gcc compiler that shipped with SnowLeopard leaves the -lgcc_s off the link line when targeting SnowLeopard. If there is a newer libgcc_s with new functions added, then the link line needs to change to "-lSystem -lgcc_s", that way the linker will find the most routines in libSystem.dylib and only the new functions from libgcc_s.dylib. Thus all linkage units will use the same unwinder. -Nick On Sep 18, 2009, at 8:16 AM, Jack Howarth wrote: > I realize this is off-topic for the list, but I th...

Hi Jack, Are you packaging all the static libraries that lld produces as part of the package ? PS : When I build on x86_64, I only get a 9M image for lld.
