I can try it next week once I have my machine set up again. I’m unable to try it until then, unfortunately. Also, I noticed that JRuby is sharing the same implementation (or similar), but both are based on FFI, not straight up Ruby. Has anyone started working on an IronRuby FFI impl?

It would actually be better not to use FFI whenever possible. Native code interop is platform specific and thus would require us to maintain multiple implementations. If there is a managed API in Mono that does what we need we should use it.

It would actually be better not to use FFI whenever possible. Native code interop is platform specific and thus would require us to maintain multiple implementations. If there is a managed API in Mono that does what we need we should use it.

I can try it next week once I have my machine set up again. I’m unable to try it until then, unfortunately. Also, I noticed that JRuby is sharing the same implementation (or similar), but both are based on FFI, not straight up Ruby. Has anyone started working on an IronRuby FFI impl? If not, would it be better to start working on this and get Etc working with FFI? Ryan R.

Well, I’m still trying to get my environment set up and having little luck. Still getting used to Mac OS X and \*nix development. Has anyone else attempted the fix? Hopefully I’ll have this sorted soon and can get on it. Regards, Ryan R.
