gcc for i386-elf, on 64bit ubuntu machine?

[minsf]

hi there,
could someone tell me how to get gcc/g++ for i386-elf target?
i am running ubuntu 9.10 64bit.
i installed g++ via the build-essentials package (apt-get install build-essentials).
this means that when i compile

g++ -o hello hello.cpp

then with

file hello

i see that i got ELF binaries for x86_64-linux-gnu, which work great on my machine.
but i am taking a class in which we need to build binaries for i386-elf, so i wonder how to do it.
is there some package that i should install?
thanks

You could set up a cross-compile environment, although that's probably more work than you want. Personally, I would set up Bloodshed in Wine.

i'd actually like to install it from source.
after a frustrating week, i've finally been able to compile binutils, gcc and libgcc from source with target i386-elf.
anyone knows of a good reference about cross-compiling glibc from source?
