This means that in order to # load the file within a Ruby program later, that directory structure will # have to be followed, e.g. "require 'test/foo'". # # 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 Config::CONFIG['sitearchdir'] that mimics your local # filesystem when you run 'make install'. # # 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'.
