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+. + # + # Yields the configuration part of the makefile to be generated, as an array + # of strings, if the block is given.
