# This is a general-purpose makefile for use with GNU make. It can be downloaded

31

# from http://www.waxworlds.org/edam/software/general-purpose-makefile where you

32

# can also find more information/documentation on it's use. The following text

33

# can only really be considered a reference to it's use.

34

#

35

# To use this makefile, put a file named "Makefile" in your project directory.

36

# Add all your project's settings to your Makefile and then include this file

37

# from it. For example, your Makefile might look something like this:

38

#

39

# TARGET = my_program

40

# SOURCES = main.cc foo.cc

41

# LIBRARIES = bar

42

# include ~/src/edam.mk

43

#

44

# A complete list of all the settings you can use in your Makefile follows. It

45

# should be noted, though, that some settings are better defined in the shell's

46

# environment and/or specified on the make command line than hard-coded straight

47

# in to the Makefile. For example, the "DEBUGMODE" is an ideal candidate for

48

# exporting from your shell:

49

# export DEBUGMODE=1

50

# and overridding on the command line when necessary:

51

# make DEBUGMODE=

52

#

53

# It should also be noted that boolean parameters should either be undefined (or

54

# defined as an empty string) for "off", and defined as "1" for "on"; as in the

55

# above example with setting DEBUGMODE.

56

#

57

# Here is a list of all configuration parameters:

58

#

59

# DEBUGMODE Boolean. Build a debugable version of the target suitable for

60

# debugging with gdb. It's probably better to set this from the

61

# command line or the shell's environment than to hard-code it.

62

# PROFILEMODE Boolean. When set, DEBUGMODE is also implied. Build a profiling

63

# version of the target, for use with gprof. It's probably better

64

# to set this from the command line or the shell's environment

65

# than to hard-code it.

66

#

67

# LINKSTATIC Boolean. Set to build a target that staticly links against all

68

# its libraries and doesn't use shared libraries.

69

#

70

# MKSTATICLIB Boolean. Target type: Set to build a static library target. If

71

# neither this nor MKSHAREDLIB are set, the target defaults to a

72

# binary executable.

73

# MKSHAREDLIB Boolean. Target type: Set to build a shared library target. If

74

# neither this nor MKSTATICLIB are set, the target defaults to a

75

# binary executable.

76

# NOLIBPREFIX Boolean. When building a static or shared library, do not ensure

77

# that the target's name is prefixed with "lib".

78

#

79

# TARGET The name of the target file.

80

#

81

# SOURCES A list of all source files of whatever language. The language

82

# type is determined by the file extension.

83

#

84

# LIBRARIES A list of libraries to link against. Don't include the 'lib'

85

# prefix.

86

#

87

# SUBDIRS A list of subdirectories to build before attempting to build the

88

# target. These subdirectories are also included in a clean_all.

89

#

90

# SUBPROJS A list of the names of other makefiles to run before attempting

91

# to build the target. This allows you to build multiple targets.

92

# Note that ".mk" is appended to the subproject names. These

93

# subprojects are also included in a clean_all.

94

#

95

# CPPFLAGS Flags to give to the C and C++ compilers

96

# CFLAGS Flags to give to the C compiler

97

# CXXFLAGS Flags to give to the C++ compiler

98

# DFLAGS Flags to give to the D compiler

99

# ASFLAGS Flags to give to the assembler

100

# LDFLAGS Flags to give to the linker before librarys

101

# LDPOSTFLAGS Flags to give to the linker after libraries

102

#

103

# This general-purpose makefile also defines the following goals for use on the

104

# command line when you run make:

105

#

106

# all This is the default if no goal is specified. It builds subdirs

107

# and subprojects first and then the target.

108

#

109

# subdirs Goes through the list of specified subdirectories, changing to

110

# them, and runs make there.

111

#

112

# subprojs Goes through the list of specified subprojects, running the

113

# makefiles for each of them.

114

#

115

# target Builds the target of your Makefile.

116

#

117

# run Builds the target of your Makefile and, if successful, runs it.

118

# This is not available if you're building a library of some kind.

119

#

120

# clean Deletes temporary files.

121

#

122

# clean_all Deletes temporary files and then goes through then project's

123

# subdirectories doing the same.

124

#

125

# <subdir> Builds the specified subdirectory from those that are listed for

126

# the project.

127

#

128

# <subproj> Builds the specified subproject from those listed for the

129

# project.

130

#

131

# <file> Builds the specified file, either an object file or the target,

132

# from those that that would be built for the project.

133

#

134

# Please report any problems to Tim Marston <edam@waxworlds.org>

135

#

136

# Known shortcommings:

137

# - Using C is probably broken because g++ is currently used for linking. We

138

# should be using ld and specifying the crt libs as required by the sources.
