Dynamic linking problems with powerpc-linux cross & glibc-2.1.3

[greyham at research dot canon dot com dot au (Graham Stoney)]

Hi there,

I'm wondering if anyone could provide me a couple of pointers with a problem
I'm having getting dynamic linking to work with a powerpc-linux cross
compiler and the latest binutils snapshot, linking against cross-compiled
glibc-2.1.3.

I've got things to the stage where the compiler front end (powerpc-linux-gcc)
can build a working Hello World, statically linked against glibc:
% powerpc-linux-gcc -static hello.c

Dynamic linking is causing me grief however, as follows:
% greyham@brixi% powerpc-linux-gcc hello.c
/opt/gcc-2.95.2/powerpc-linux/bin/ld: warning: ld.so.1, needed by /opt/ppc.linux/glibc-2.1.3-8xx/lib/libc.so.6, not found (try using --rpath)
/opt/ppc.linux/glibc-2.1.3-8xx/lib/libc.so.6: undefined reference to `_dl_init_next@GLIBC_2.0'

As the warning points out, libc.so.6 can't find ld.so.1. But it's right there
alongside libc.so.6 in /opt/ppc.linux/glibc-2.1.3-8xx/lib/ld.so.1, where the
glibc install put it!

Setting LD_LIBRARY_PATH helps powerpc-linux-gcc to work, but breaks a bunch
of other things because I'm cross compiling from i686-linux, and don't want
native dynamically linked programs to try to use the powerpc-linux ld.so.1.

Using --rpath also helps, but again this should be unnecessary since the
compiler frontend is supposed to tell the linker this kind of stuff.

Can anyone give me a pointer please?

Thanks,
Graham
