unrecognised emulation mode after building powerpc-linux cross


Hi there,

I'm wondering if anyone can help me out with a problem I'm having building a
powerpc-linux cross development environment on a Red Hat Linux
i686-pc-linux-gnu system, using gcc-2.95, binutils-2.9.1.0.25 and newlib-1.8.1.

Each was configured in their own objdir, as follows:

../../binutils-2.9.1.0.25/configure --target=powerpc-linux --prefix=/home/server/greyham/linux/ppc/tooldir/host/i686-pc-linux-gnu

../../gcc-2.95/configure --target=powerpc-linux --prefix=/home/server/greyham/linux/ppc/tooldir/host/i686-pc-linux-gnu --with-newlib --with-gnu-as --with-gnu-ld

../../newlib-1.8.1/configure --target=powerpc-linux --prefix=/home/server/greyham/linux/ppc/tooldir/host/i686-pc-linux-gnu

I then built and installed the compiler, binutils and newlib; but building my
hello world executable fails as follows:

bash$ powerpc-linux-gcc hello.c
/home/server/greyham/linux/ppc/tooldir/host/i686-pc-linux-gnu/powerpc-linux/bin/ld: unrecognised emulation mode: elf32ppclinux
Supported emulations: elf32ppc

This looks like a simple configuration problem, but can anyone suggest why gcc
is asking for the wrong emulation from ld? (For the adventurous, the output of
gcc with -v is included below)

Thanks,
Graham


bash$ powerpc-linux-gcc -v hello.c
