just need the right toolchain installed. I personally use Debian with the
gcc-4.7-arm-linux-gnueabi package from the Emdebian repo. (I believe Ubuntu
and other distros have similar packages). From there it's just a simple
matter of passing the right triple to the configure script.

Then you can run it like so:

the basic gist of it.
I am trying to follow these instructions and also
./configure --prefix=/usr/local/stow/rust-pi-20140608 --target=arm-unknown-
sudo make install
cfg: build triple x86_64-unknown-linux-gnu
cfg: host triples x86_64-unknown-linux-gnu
cfg: target triples x86_64-unknown-linux-gnu arm-unknown-linux-gnueabihf
cfg: non-build target triples arm-unknown-linux-gnueabihf
cfg: enabling more debugging (CFG_ENABLE_DEBUG)
cfg: host for x86_64-unknown-linux-gnu is x86_64
cfg: host for arm-unknown-linux-gnueabihf is arm
cfg: os for x86_64-unknown-linux-gnu is unknown-linux-gnu
cfg: os for arm-unknown-linux-gnueabihf is unknown-linux-gnueabihf
cfg: using CC=gcc (CFG_CC)
cfg: no pdflatex found, deferring to xelatex
cfg: no xelatex found, deferring to lualatex
cfg: no lualatex found, disabling LaTeX docs
cfg: no pandoc found, omitting PDF and EPUB docs
cfg: no llnextgen found, omitting grammar-verification
A rustc gets built, but it targets Intel:
$ rustc -C target-cpu=help hello.rs
Available CPUs for this target:
amdfam10 - Select the amdfam10 processor.
athlon - Select the athlon processor.
athlon-4 - Select the athlon-4 processor.
athlon-fx - Select the athlon-fx processor.
athlon-mp - Select the athlon-mp processor.
athlon-tbird - Select the athlon-tbird processor.
athlon-xp - Select the athlon-xp processor.
athlon64 - Select the athlon64 processor.
athlon64-sse3 - Select the athlon64-sse3 processor.
