# A Makefile for Arduino Sketches This is a very simple Makefile which knows how to build Arduino sketches. Until March 2012, this was simply posted on my website where you can still find [what documentation](http://mjo.tc/atelier/2009/02/arduino-cli.html "Documentation") exists. If you're using Debian or Ubuntu, you can find this in the arduino-mk package. # Important Changes, 2012-04-29 I've rejigged the path calculations so that: 1. Few, if any paths, need to specified in the project specific Makefiles. 1. The paths can be grabber from the environment e.g. set up in a user's .bashrc. 1. It should be easier to move between e.g. Mac and Linux. I'm indebted to Christopher Peplin for making me think about this, and indeed for contributing code which did similar things in different ways. The upshot of all this is that you'll need to set up some variables if you want this to work: On the Mac you might want to set: ARDUINO_DIR = /Applications/Arduino.app/Contents/Resources/Java ARDMK_DIR = /usr/local On Linux, you might prefer: ARDUINO_DIR = /usr/share/arduino ARDMK_DIR = /usr/local AVR_TOOLS_DIR = /usr The Makefile also delegates resetting the board to a short Perl program. You'll need to install Device::SerialPort to use it though. You'll also need the YAML library to run ard-parse-boards. On Debian or Ubuntu: apt-get install libdevice-serial-perl apt-get install libyaml-perl On Fedora: yum install perl-Device-SerialPort yum install perl-YAML On other systems: cpanm Device::SerialPort cpanm YAML ## User Libraries In order to use Arduino libraries installed in the user's sketchbook folder (the standard location for custom libraries when using the Arduino IDE), you need to set the `ARDUINO_SKETCHBOOK` variable to point to this directory. By default it is set to `$HOME/sketchbook`.
