david-pm / NATAS

A sample C extension for Ruby that supplies a method called `natas` that returns 666

Create a super-basic C extension for Ruby

1. Make a file called extconf.rb Require mkmf, add boilerplate methods
2. Make your C file (this one is called FooBar.c) Add some boilerplate, write your C program
3. run: ruby extconf.rb This generates a Makefile
4. Run it: make This compiles your C code into a bundle.
5. I've added an init.rb file which includes the file into the Ruby load path, requires it, and loads an irb session. Notice that our natas method belongs to the FooBar module we added.
6. From inside the repl just type natas and see what happens! ☜(⌒▽⌒)☞

Otherwise, just clone this repos. Then run ruby extconf.rb, then run make, then run ruby init.rb
