# 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
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".
75
79
# TARGET The name of the target file.
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.
89
# Note that if the file 'emake.mk' exists in a subdirectory, it
90
# will be used explicitly, rather than any default makefile.
92
# SUBPROJS A list of the names of other makefiles to run before attempting
93
# to build the target. This allows you to build multiple targets.
94
# Note that ".mk" is appended to the subproject names. These
95
# subprojects are also included in a clean_all.

# CFLAGS Flags to give to the C compiler

# command line when you run make:
97
108
# all This is the default if no goal is specified. It builds subdirs
98
# first and then the target.
100
# subdirs Changes to the subdirectories specified for the project and runs
109
# and subprojects first and then the target.
111
# subdirs Goes through the list of specified subdirectories, changing to
112
# them, and runs make there.
114
# subprojs Goes through the list of specified subprojects, running the
115
# makefiles for each of them.
103
117
# target Builds the target of your Makefile.
113
127
# <subdir> Builds the specified subdirectory from those that are listed for
130
# <subproj> Builds the specified subproject from those listed for the
116
133
# <file> Builds the specified file, either an object file or the target,
117
134
# from those that that would be built for the project.
121
138
# Known shortcommings:
122
139
# - 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!
140
# should be using ld and specifying the crt libs as required by the sources.
