Mac+M1+Crystal+Lucky

This is the series of steps I followed to get Crystal and Lucky running on a Mac M1 from scratch, as of Oct. 2021.

Prerequisites

• Ensure ~/bin and /opt both exist.
• /opt will have to be created with sudo but should be owned by your user.
• Make sure your $PATH includes ~/bin. Doing so is up to you and will vary a bit depending on your shell.

Installing crystal

From this issue comment the “second gen” build comes as a tar.gz. This is a direct link to the archive.

• In /opt, extract crystal-ci-univ2nd-dev-1.tar.gz.
• In ~/bin, touch crystal ; chmod u+x crystal and then edit ~/bin/crystal to have these contents:

#!/bin/bash

export CRYSTAL_PATH='lib:/opt/crystal-ci-univ2nd-dev-1/src'

export CRYSTAL_LIBRARY_PATH="$(brew --prefix)/lib"
export LDFLAGS="/opt/homebrew/opt/openssl@1.1/lib"
export CPPFLAGS="/opt/homebrew/opt/openssl@1.1/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/openssl@1.1/lib/pkgconfig"
export PATH="/opt/homebrew/opt/openssl@1.1/bin:$PATH"

exec '/opt/crystal-ci-univ2nd-dev-1/bin/crystal' "${@}"

• which crystal should now show /Users/user/bin/crystal
• crystal -v should now show:

Crystal 1.2.0-dev [d7f25e0c6] (2021-09-15)

LLVM: 10.0.0
Default target: aarch64-apple-darwin

Setting up shards

• Clone the shards repo to /opt/shards
• From /opt/shards run make
• From ~/bin run ln -s /opt/shards/bin/shards
• which shards should now point to /opt/shards/bin/shards`
• shards --version should be Shards 0.15.0 [6471b2b] (2021-10-04)

Setting up lucky cli

• Clone the lucky_cli repo to /opt/lucky_cli
• From /opt/lucky_cli run shards build
• From ~/bin run ln -s /opt/lucky_cli/bin/lucky
