This repository contains the GNU AVR Toolchain as formulae for Homebrew.

AVR is a popular family of micro-controllers, used for example in the Arduino project.

• GCC 9.4.0 - default, provided as avr-gcc or avr-gcc@9
• GCC 5.5.0 - provided as avr-gcc@5
• GCC 8.5.0 - provided as avr-gcc@8
• GCC 10.3.0 - provided as avr-gcc@10
• GCC 11.3.0 - provided as avr-gcc@11
• GCC 12.2.0 - provided as avr-gcc@12
• Binutils 2.40.0 - provided as avr-binutils
• AVR Libc 2.1.0 - provided as a resource for each GCC formula
• GDB 10.1 - provided as avr-gdb

Support for older GCC versions (4, 6, 7) has been removed. Please, raise an issue if you need one back.

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.

brew info avr-gcc, brew help, man brew, or the Homebrew documentation.
