It seems like the RPi tools repo only works on Linux machines. Any ideas how I could build the cross-compiler on OS X?

I'm very new at this. I'm trying to install this Rust compiler in order to use librespot. I have followed the instructions and downloaded pi-tools and rust to my home directory successfully. But when I type "export PATH=~/pi-tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin:$PATH" (standing in the /rust directory) I'm not sure if something is happening, what is it supposed to do?
I tried to run the next line "./configure --target=arm-unknown-linux-gnueabihf --prefix=$HOME/pi-rust && make && make install" and it starts configuring, but then I get an error "CFG_CMAKE needed". is this because the pi-tools is not exported correctly?

Hello there,

If I run configure in rust directory, I get the following:

configure: looking for configure programs
configure: found program 'cmp'
configure: found program 'mkdir'
configure: found program 'printf'
configure: found program 'cut'
configure: found program 'head'

configure: found program 'date'
configure: found program 'tr'
configure: found program 'sed'
configure: found program 'file'
configure: found program 'make'
configure: inspecting environment
configure: error: unknown CPU type: armv6l

But until now, I did not find any information about that problem.

Information about CPU on my raspberry (1, rev b, imho):

Hi, love your small project. do you think it makes sense to push content of pi folder to crates.io as a separet crate?

Thanks!

Hello, thanks to your guide "Compiling the compiler" I got a nice RPi Rust cross-compiler working last night. However there was one roadblock that took a while for me to figure out, which was that I had to set LD_LIBRARY_PATH after the installation. I now know that the final output of make install is to tell you to make sure you set your LD_LIBRARY_PATH, but I guess I wasn't paying attention to it at first, and then running rustc gave me a rustc: symbol lookup error: rustc: undefined symbol: _ZN10lang_start20he89a41cbe8ac26fcWjeE error.

So I'd like to suggest adding the setting of LD_LIBRARY_PATH as an explicit step in the instructions, as I think it would help others like me.
