# You also need to set up a couple of environment variables. ARDUINODIR should

47

# be set to the path where you unpacked the arduino software from arduino.cc

48

# (it defaults to ~/opt/arduino if unset). You might be best to set this in

45

# The Arduino software (version 1.0 or later) is required. If you are using

46

# Debian (or a derivative), type `apt-get install arduino`. Otherwise, you

47

# will have to download the Arduino software manually from http://arduino.cc/.

48

# It is suggested that you install it at ~/opt/arduino if you are unsure.

49

#

50

# If you downloaded the Arduino software manually and unpacked it somewhere

51

# other than ~/opt/arduino, you will need to set up ARDUINODIR to be the path

52

# where you unpacked it. (If unset, ARDUINODIR defaults to ~/opt/arduino and

53

# then /usr/share/arduino, in that order.) You might be best to set this in

49

54

# your ~/.profile by adding something like this:

50

55

#

51

56

# export ARDUINODIR=~/somewhere/arduino-1.0

52

57

#

53

# You will also need to set BOARD to the type of arduino you're using. This

54

# can be done when running make (or you could set a default in ~/.profile and

55

# override it as necessary). For example:

58

# You will also need to set BOARD to the type of Arduino you're building for.

59

# Type `make boards` for a list of acceptable values. You could set a default

60

# in your ~/.profile if you want, but it is suggested that you specify this at

61

# build time, especially if you work with different types of Arduino. For

62

# example:

56

63

#

57

# $ export BOARD=uno
