--target=powerpc-unknown-elf, binutils-2.15?

[Torsten Mohr <tmohr at s dot netic dot de>]

Hi,

i try to set up a toolchain for powerpc-unknown-elf.

I installed binutils-2.15 (--target=powerpc-unknown-elf)
for this.
I configured gcc-core-3.4.1 with --prefix=powerpc-unknown-elf \
--prefix=/opt/powerpc-unknown-elf

When i now try to compile gcc-core-3.4.1, i get:

...
if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi
/rest/tmp/bgcc/gcc/xgcc -B/rest/tmp/bgcc/gcc/

schleim:/rest/tmp/bgcc # type powerpc-unknown-elf-as
powerpc-unknown-elf-as is /opt/powerpc-unknown-elf/bin/powerpc-unknown-elf-as

Do i need to pass some more options to binutils so that it recognizes
"-mppc"?

Is it ok to use binutils-2.15 and gcc-core-3.4.1 together?

Can anybody give me some more hints on how to set up a cross toolchain
for powerpc-unknown-elf?


Thanks for any hints,
Torsten.
