Hi,

I am running OS x 10.4 on an Intel processor and am trying to create a
cross compiler that will compile to i386-elf. I started off by
downloading binutils 2.17 and built it targeted to that architecture.
Everything seemed to go fine. Then I downloaded gcc-core-4.2.0 and
configured it with the following parameters:
--prefix=~/tmp/cross-compiler --target=i386-elf --enable-languages=c.
The configure seemed to go fine and I followed it with a make. The
compile seems to fail while building ssp.lo with the following errors
(snipped for sanity):

../../../gcc-4.2.0/libssp/ssp.c: In function '__guard_setup':

This is my first time building a cross compiler so I don't know if I'm
missing a critical step or something. Does anybody have any ideas?

Thank you,

Ben
