hello,  
I am trying to obtain a sound library so I can write morse code practice  
applications in ruby, I came across RUDL but can’t seem to get it to  
build on my machine. Here’s the output I get when I build it:  
[http://pastie.org/877083](http://pastie.org/877083)

I followed the dependency instructions that came with the library, and I  
see there seems to be a patch necessary to build it. Either I don’t  
understand how to apply the patch, or there’s another bug.

Anyone got this working, or can you recommend a gem/lib that will let me  
make noise w/ ruby?  
bonus pretzels if it works in jruby!

thanks,  
GB Hoyt

See [http://aur.archlinux.org/packages.php?ID=24767](http://aur.archlinux.org/packages.php?ID=24767)

ruby-1.9.1.patch is the patch you need to build rudl-0.8. You may  
need the gcc4.patch from that page as well, at least on Arch  
Linux.

There’s a full set of sound libraries shipped with every Java runtime,  
and they’re as easy to use from JRuby as any Ruby library (with  
nothing to build or install either!)

Here’s a couple demos using the midi support in the JRE from Ruby:

I’ve not used the other sound libraries (basic formats built-in, many  
third-party libs for other sound formats), but pretty much anything  
you want to play ought to have a library for it.
