Fw: Lua was Re: Quickstart Build instructions

Sorry for the direct mail, Gedare. The Lua mailing list I'm on automatically forwards to all users in the email because it re-writes the return mail address but leaves the persons name on it. I keep forgetting that rtems mailing list does not.

Original question below...

Thanks

Subject: Re: Lua was Re: Quickstart Build instructions

Thanks for the help! I've managed to load a lua script from a string in my C application. While novel, that in itself isn't very functional. I'll need to figure out how to run other scripts as well as C based components.

I'd like to start with getting other Lua scripts running. My goal is to load a library called penlight that's a few dozens of files. Is there a utility for creating and loading resources? I'll also look at compiling the files using the luac compiler, but that's outside of rtems.

Very exciting!

Russ
