| # 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. "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 RbConfig::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'. That,
 | |
| # in turn, will create the following file tree when installed via the
 | |
| # 'make install' 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.
