Hi Ralf, Prokash,

Apple's ld takes a -map <file> argument that generates a map file along
with the output. A quick test using ./libtool --mode=link --tag=CC gcc
-o libfoo.la foo.lo -rpath /foo -Wl,-map,foo.map works for me though.

Prokash, please show the link line, the error, ld -v, and ./libtool
--version.

Thanks,
Peter
