Installing homebrew-avr formulae

First, make sure you have xcode command line developer tools installed with

$ xcode-select --install

Then, just run the following to install the latest version of avr-gcc:

$ brew tap osx-cross/avr
$ brew install avr-gcc

If you want to install a different version:

$ brew install avr-gcc@{x}

Where {x} being the version number such as avr-gcc@8 or avr-gcc@10

Note: only the default version will be available in your $PATH. The other ones are keg-only and thus won't be available in /usr/local/bin.

You can run brew info avr-gcc or brew info avr-gcc@{x} for more information on the flags available.
