Cross compiling with the i386-elf toolchain?

[David Smoot]

I'm trying to learn cross compiling out of curiousity for an idea I'm
playing with at work.

I have a powerbook G4 (ppc) with the i386-elf port for GCC and binutils
installed. I'm trying to compile a simple "hello world" application that
just has a single printf.

In a terminal I type:
i386-elf-gcc-3.4.3 -c main.c
and I get the expected main.o

now I type
i386-elf-gcc-3.4.3 -o hello main.o
and I get:
/opt/local/lib/gcc/i386-elf/3.4.3/../../../../i386-elf/bin/ld: crt0.o: No
such file: No such file or directory

So my problem is linking. I've exhausted my google abilities and
knowledge. I think I need something like:
i386-elf-gcc-3.4.3 -o hello main.o -I/opt/local/i386-elf/include -Wl,
-nostdlib but so far I cannot figure it out.

If someone will help me figure out a simple "hello world" cross compile
recipe for these tools I would be most appreciative.

Thanks
David

Cross toolchains such as MacPort's i386-elf are target agnostic. They
rely on a minimum runtime glue code (in crt0.o file). This library
highly depends on the kind of target you are targetting. You can
either compile/write one yourself in assembly language (that's the
approach for targets with open-source crt0 file) or use one from the
SDK of the platform you are targetting.

HTH,

Paul
