Instructions for armv6 (Raspberry Pi 1 / Zero)

[oconnor663]

Here's an example of the above that just worked for me, but done entirely from the command line rather than a config file:

rustup target add arm-unknown-linux-gnueabi
git clone https://github.com/raspberrypi/tools $HOME/rpi_tools
RUSTFLAGS="-C linker=$HOME/rpi_tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc" cargo build --target arm-unknown-linux-gnueabihf --tests

@theronic Yes, you only need to change the linker for the resulting binary to work.
Something like this in .cargo/config:

# default target
target = "arm-unknown-linux-gnueabihf"

[target.arm-unknown-linux-gnueabihf]
linker = "/foo/raspberrypi-tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-cc"

I'm currently using official compiler build for manual cross compilation from x86_64 Linux to ARMv6 (for Pi Zero).

So, cargo build --target=arm-unknown-linux-gnueabihf should work for Raspberry Pi Zero?
