I want to write Rust code on my computer (x86_64, Ubuntu 14.04) and produce arm executables. I found hints on the internet, but not a concise set of instructions on what to do. So I wrote them down exactly:
apt-get install g++-arm-linux-gnueabihf
git clone https://github.com/mozilla/rust.git
mkdir rust/build-cross
cd rust/build-cross
../configure --target=arm-unknown-linux-gnueabihf --prefix=$HOME/local/rust-cross
make -j8 && make install
| #!/bin/sh | |
| while true; do | |
| echo -n " > " | |
| read line | |
| TMP=`mktemp` | |
| rustc - -o $TMP <<EOF | |
| #[feature(globs, macro_rules, struct_variant)]; | |
| extern mod extra; | |
