The compiler is configured as follows: 
 
"~/src/gnu/gcc-3.2.3/configure" \ 
  --prefix="/opt/linux-cross" \ 
  --build="i686-pc-linux-gnu" --host="i686-pc-linux-gnu" \ 
  --target="powerpc-unknown-linux-gnu" \ 
  --with-gnu-as --with-gnu-ld --enable-threads=posix \ 
  --enable-languages=c,c++ --with-system-zlib \ 
  --with-headers="${target}/usr/include" \ 
  --with-libs="${target}/usr/lib" 
 
${target} is the root of the target file system; glibc-2.3.2 is 
installed there. The exact failure is:

This result has been obtained using gcc-3.2.3, glibc-2.3.2 and binutils-2.13.2.1. 
I also tried gcc-3.3, with identical results.

Subject: RE:  Cannot build cross gcc /w shared libs

Yes, you are right, libc.so is actually a linker script
containing absolute paths, and I installed glibc in a
directory different from what I configured it for (I
wanted to export it via NFS as the target's root fs).

Thank you very much for your assistance. Just one last question:
once --with-sysroot becomes available, will I then be able to
do this sort of thing?

Thanks again,
Thomas

Thomas,

yes --with-sysroot should do what you're asking, in the form of --sysroot=${target} in your case. 
If that fails, by all means, send another bug reports. Given all the effort put into making it work, 
I'm sure people will be responsive. I'm closing this report as not actually a bug, although if you 
have a suggestion where this information should go, send me an e-mail, and I'll reopen this as 
a documentation enhancement request...

Dara
