Installing the AVR toolchain on OSX Lion
I’m working on an Arduino-based project and want a more powerful IDE to code in, since the Arduino IDE is somewhat restrictive.
In order to run under Eclipse, the AVR toolchain needs to be installed (avr-gcc, avr-binutils, avr-libc, avr-gdb, avrdude). I didn’t want to install a binary package for these tools; instead, I wanted a natively-compiled version of the tools, preferably using brew, since this is my package manager of choice these days.
I finally found a homebrew formula that was written specifically for the install. Here’s how to do it, assuming you cloned the homebrew repo to /usr/local/Library
git clone https://github.com/larsimmisch/homebrew-alt.git LibraryAlt
brew install LibraryAlt/avr/avr-libc.rb
brew install avrdude dfu-programmer
Many thanks goes to Lars Immisch for maintaining his homebrew-alt repo at https://github.com/larsimmisch/homebrew-alt
