- # Generates the Makefile for your extension, passing along any options and

- # The +target+ name should correspond the name of the global function name
- # defined within your C extension, minus the +Init_+. For example, if your
- # C extension is defined as +Init_foo+, then your target would simply be
- # "foo".
- #
- # If any "/" characters are present in the target name, only the last name
- # is interpreted as the target name, and the rest are considered toplevel
- # directory names, and the generated Makefile will be altered accordingly to
- # follow that directory structure.
- #
- # For example, if you pass "test/foo" as a target name, your extension will
- # be installed under the "test" directory. This means that in order to
- # load the file within a Ruby program later, that directory structure will
- # have to be followed, e.g. <code>require 'test/foo'</code>.
- #
- # The +srcprefix+ should be used when your source files are not in the same
- # directory as your build script. This will not only eliminate the need for
- # you to manually copy the source files into the same directory as your
- # build script, but it also sets the proper +target_prefix+ in the generated
- # Makefile.
- #
- # Setting the +target_prefix+ will, in turn, install the generated binary in
- # a directory under your <code>RbConfig::CONFIG['sitearchdir']</code> that
- # mimics your local filesystem when you run <code>make install</code>.
- #
- # For example, given the following file tree:
- #
- # ext/
- # extconf.rb
- # test/
- # foo.c
- #
- # And given the following code:
- #
- # create_makefile('test/foo', 'test')
- #
- # That will set the +target_prefix+ in the generated Makefile to "test".
- # That, in turn, will create the following file tree when installed via the
- # <code>make install</code> command:
- #
- # /path/to/ruby/sitearchdir/test/foo.so
- #
- # It is recommended that you use this approach to generate your makefiles,
- # instead of copying files around manually, because some third party
- # libraries may depend on the +target_prefix+ being set properly.
- #
- # The +srcprefix+ argument can be used to override the default source
