Hi,
buildd a linux/x86 -> darwin/x86 cross compiler, the libstdc++ compile calls
nm -P .libs/bitmap_allocator.o .libs/pool_allocator.o .libs/mt_allocator.o
.libs/codecvt.o .libs/compatibility.o .libs/complex_io.o .libs/ctype.o
...
which barfs with
../libsupc++/.libs/libsupc++convenience.a|nm: .libs/bitmap_allocator.o: File
format not recognized
nm: .libs/pool_allocator.o: File format not recognized
nm: .libs/mt_allocator.o: File format not recognized
it seems that the
libstdc++-v3/scripts/make_exports.pl
script is hardcoded to "nm" iso. the value for NM_FOR_TARGET.
This happens with configuring as
/home/hanwen/vc/gub/target/darwin-ppc/src/gcc-4.1.0/configure
--prefix=/home/hanwen/vc/gub/target/darwin-ppc/install/gcc-root/usr
--program-prefix=powerpc-apple-darwin7-
