Possibly would be a DLL for Windows?

Can you paste *exactly* what you see? If it returns "true" then the
extension was loaded correctly. Or did it crash IRB, i.e. you didn't
even get a prompt back?

the file is named "mytest.so" and you're probably on a case sensitive file system. I'm guessing you don't have a file named MyTest.so (or .rb).

look at your doco for Kernel#require to see what it does. You can use `ri` for that or look it up on rubydoc or somesuch.
