# To use this makefile, copy arduino.mk in to your project directory. Or, you

40

# could save it somewhere (I keep mine at ~/src/arduino.mk) and create a

41

# symlink to it in your project directory, named "Makefile". For example:

# The Arduino software (version 1.0 or later, including the new 1.5 BETA) is

46

# required. On GNU/Linux you can probably install the software from your

47

# package manager. If you are using Debian (or a derivative), try `apt-get

48

# install arduino`. Otherwise, you can download the Arduino software manually

49

# from http://arduino.cc/. It is suggested that you install it at

50

# ~/opt/arduino (or /Applications on OS X) if you are unsure.

49

# is suggested that you install it at ~/opt/arduino (or /Applications on OS X)

50

# if you are unsure.

51

#

52

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

53

# *other* than ~/opt/arduino (or /Applications), you will need to set up the

54

# ARDUINODIR environment variable to be the directory where you unpacked it.

55

# (If unset, ARDUINODIR defaults to some sensible places). You could set this

56

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

53

# other than ~/opt/arduino (or /Applications), you will need to set up the

54

# ARDUINODIR environment variable to be the path where you unpacked it. (If

55

# unset, ARDUINODIR defaults to some sensible places). You could set this in

56

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

57

#

58

# export ARDUINODIR=~/somewhere/arduino-1.0.5

58

# export ARDUINODIR=~/somewhere/arduino-1.0

59

#

60

# For each project, you will also need to set BOARD to the type of Arduino

61

# you're building for. Type `make boards` for a list of acceptable values.

62

# For example:

63

#

64

# $ export BOARD=uno

65

#

66

# Note that if you're using the newer 1.5 Arduino software and the board you

67

# want to use is availble with different processors, you will also need to

68

# specify one. For example:

69

#

70

# $ export BOARD=mini.atmega328

71

#

72

# You may also need to set SERIALDEV if your Arduino is not detected correctly.

65

# $ make

66

#

67

# You may also need to set SERIALDEV if it is not detected correctly.

73

68

#

74

69

# The presence of a .ino (or .pde) file causes the arduino.mk to automatically

75

# determine values for SOURCES, TARGET and which libraries to pull-in to the

76

# build (although you can still override thius by setting LIBRARIES). Any .c,

77

# .cc and .cpp files in the project directory (or any "util" or "utility"

78

# subdirectories) are automatically included in the build and are scanned for

79

# Arduino libraries that have been #included. Note, there can only be one .ino

80

# (or .pde) file in a project directory and if you want to be compatible with

81

# the Arduino IDE, it should be called the same as the directory name.

70

# determine values for SOURCES, TARGET and LIBRARIES. Any .c, .cc and .cpp

# files in the project directory (or any "util" or "utility" subdirectories)

72

74

# a project directory and if you want to be compatible with the Arduino IDE, it

75

# should be called the same as the directory name.

82

76

#

83

77

# Alternatively, if you want to manually specify build variables, create a

84

78

# Makefile that defines SOURCES and LIBRARIES and then includes arduino.mk.

85

# (You don't need to define TARGET). You can also specify the BOARD here, if

79

# (There is no need to define TARGET). You can also specify the BOARD here, if

86

80

# the project has a specific one. Here is an example Makefile:

87

81

#

88

82

# SOURCES := main.cc other.cc

90

84

# BOARD := pro5v

91

85

# include ~/src/arduino.mk

92

93

# Here is a complete list of environment variables that affect the build:

87

# Here is a complete list of configuration parameters:

94

88

#

95

# ARDUINODIR The directory where the Arduino software resides on your system.
