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

29

31

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

30

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

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

35

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

71

73

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

72

74

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

73

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".

74

78

#

75

79

# TARGET The name of the target file.

76

80

#

83

87

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

84

88

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

85

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

#

86

95

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

87

96

# CFLAGS Flags to give to the C compiler

88

97

# CXXFLAGS Flags to give to the C++ compiler

# command line when you run make:

96

105

#

97

106

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

98

# first and then the target.

99

#

100

# subdirs Changes to the subdirectories specified for the project and runs

101

# make in them.

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.

102

114

#

103

115

# target Builds the target of your Makefile.

104

116

#

113

125

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

114

126

# the project.

115

127

#

128

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

129

# project.

130

#

116

131

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

117

132

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

120

135

#

121

136

# Known shortcommings:

122

137

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

123

# should switch to ld and specify the correct crt as required by source files.

124

# - Currently can only specify one target. If we could specify several targets

125

# though, we'd need separate sources, libraries and build params for each!

138

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