# You also need to set up a couple of environment variables. ARDUINODIR should
47

46
# Debian (or a derivative), type `apt-get install arduino`. Otherwise, you

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

# If you downloaded the Arduino software manually and unpacked it somewhere
51

53
# then /usr/share/arduino, in that order.) You might be best to set this in

51
56
# export ARDUINODIR=~/somewhere/arduino-1.0
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
