Description Han-Wen Nienhuys 2006-03-01 15:54:12 UTC 
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- --prefix=/home/hanwen/vc/gub/target/darwin-ppc/system/usr/cross/ --with-slibdir=/usr/lib/ --target=powerpc-apple-darwin7 --with-sysroot=/home/hanwen/vc/gub/target/darwin-ppc/system/  --with-as=/home/hanwen/vc/gub/target/darwin-ppc/system/usr/cross/bin/powerpc-apple-darwin7-as --with-ld=/home/hanwen/vc/gub/target/darwin-ppc/system/usr/cross/bin/powerpc-apple-darwin7-ld
--enable-static --enable-shared  --enable-languages=c,c++  --enable-libstdcxx-debug
Comment 1 Han-Wen Nienhuys 2006-03-01 15:54:48 UTC 
oops, changed target triplet.
Comment 2 Andrew Pinski 2006-03-01 16:55:26 UTC 
Yes most of the darwin configuration stuff is done only for native builds.
Comment 3 Benjamin Kosnik 2006-03-17 18:29:28 UTC 
Solution is to make

make_exports.pl.in 

with NM_FOR_TARGET substition for current uses of 'nm'

This is done with other scripts. 

This is low-priority, but this is enough of a hint so that you should be able to try and fix it.

I think the correct Target Milestone is 4.1.1...
