Mac-specific installation doesn't work

[harrisonturton]

Hello,

On this page, it asks us to run the following commands:

$ # GDB
$ brew cask install gcc-arm-embedded

$ brew install openocd

$ brew install qemu

Unfortunately, I get the error when executing the first command:

Error: Cask 'gcc-arm-embedded' is unavailable: No Cask with this name exists.

And when trying to tap Caskroom/tap:

htmacbook:local harrisonturton$ brew tap Caskroom/tap
==> Tapping caskroom/tap
Cloning into '/usr/local/Homebrew/Library/Taps/caskroom/homebrew-tap'...
remote: Repository not found.
fatal: repository 'https://github.com/Caskroom/homebrew-tap/' not found
Error: Failure while executing; `git clone https://github.com/Caskroom/homebrew-tap /usr/local/Homebrew/Library/Taps/caskroom/homebrew-tap --depth=1` exited with 128.

Any ideas? Not sure whats wrong.

I don't have a Mac, but is this command case sensitive: brew tap caskroom/cask ? Specifically the 'c' in caskroom?

http://caskroom.io/ -> brew tap caskroom/cask
https://docs.rust-embedded.org/discovery/03-setup/macos.html -> brew tap Caskroom/tap

Once brew cask is installed, then brew cask install gcc-arm-embedded should work for you.

Also noticed that caskroom is now deprecated (see github page): https://github.com/Caskroom/caskroom.github.io

Also, gcc-arm-embedded has been removed (Homebrew/homebrew-cask#56802).

Go to the bottom of this gist, other ppl have been having the same problem:
https://gist.github.com/joegoggins/7763637

Look like you have two option:

brew tap PX4/px4
brew search px4
[ install the latest px4/px4/gcc-arm-none-eabi-XX ]

Install gcc-arm-none-eabi yourself: https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads/8-2018-q4-major
[ Add the bin folder to your path - instructions in https://gist.github.com/joegoggins/7763637 ]

@harrisonturton once you've sorted it, can you document the install process here, and possibly create a pull request with updates to:
https://github.com/rust-embedded/book/blob/master/src/intro/install/macos.md

I'll take care of it.
