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.

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.
