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

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

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

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

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

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

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

# TARGET = my_program

# SOURCES = main.cc foo.cc

# LIBRARIES = bar

# include ~/src/edam.mk

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

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

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

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

# exporting from your shell:

# export DEBUGMODE=1

# and overridding on the command line when necessary:

# make DEBUGMODE=

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

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

# above example with setting DEBUGMODE.

# Here is a list of all configuration parameters:

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

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

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

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

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

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

# than to hard-code it.

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

# its libraries and doesn't use shared libraries.

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

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

# binary executable.

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

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

# binary executable.

# TARGET The name of the target file.

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

# type is determined by the file extension.

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

# prefix.

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

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

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

# CFLAGS Flags to give to the C compiler

# CXXFLAGS Flags to give to the C++ compiler

# DFLAGS Flags to give to the D compiler

# ASFLAGS Flags to give to the assembler

# LDFLAGS Flags to give to the linker before librarys

# LDPOSTFLAGS Flags to give to the linker after libraries

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

# command line when you run make:

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

# first and then the target.

100

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

101

# make in them.

102

103

# target Builds the target of your Makefile.

104

105

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

106

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

107

108

# clean Deletes temporary files.

109

110

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

111

# subdirectories doing the same.

112

113

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

114

# the project.

115

116

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

117

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

118

119

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

120

121

# Known shortcommings:

122

# - 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!
