  #   require 'mkmf'

  #   have_func('realpath')

  #   create_makefile('foo')

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

						|
  # preprocessor constants that you may have generated through other methods.
 | 
						|
  #
 | 
						|
  # 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
 | 
						|
  # directory, i.e. the current directory.  It is included as part of the
 | 
						|
  # +VPATH+ and added to the list of +INCFLAGS+.
