Crystal: Install crystal on a raspberry pi

[ghost]

For my current project I want to run crystal on my new Raspberry Pi 3 Model B. But the installation fails every time.

What I ran:

$ curl https://dist.crystal-lang.org/apt/setup.sh | sudo bash

Where it fails: $ sudo apt-get update

What is the error: Error in request, could not read "main/binary-armhf/Packages" from Release-file

How could I solve this error? My researches say, it is a problem with the kernel, because I use raspbian and a armhf architecture, no amd64 one.

We don't (yet) provide binary packages for crystal on Raspberry Pi. Please read this if you want to install from source.

@RX14 Thanks for the answer, I hope you will provide it soon. It is an awesome programming language.

@RX14 I got an error while compiling crystal on my vm:

ubuntu@ubuntu-xenial:~$ ./bin/crystal build src/compiler/crystal.cr --cross-compile --target arm-unknown-linux-gnueabih

Error: you've found a bug in the Crystal compiler. Please open an issue, including source code that will allow us to reproduce the bug: https://github.com/crystal-lang/crystal/issues

And I build LLVM with ARM: http://llvm.org/docs/HowToBuildOnARM.html

Well, it looks like the llvm in your x86 ubuntu VM was built without ARM support. Not sure how to install that on ubuntu.
