[MacRuby-devel] are framework extern variables visible in Mac Ruby? (was: Re: how to access OpenDirectory C constants from MacRuby?)

[Laurent Sansonetti]

Hi Russell,

Sorry for the late response.

OpenDirectory.framework ships with BridgeSupport annotations, so doing "framework 'OpenDirectory'" should merge all symbols into MacRuby. If some are missing, it's likely a bug in the BridgeSupport generator, that should be reported via http://bugreport.apple.com. 

Fortunately, we are working on a new BridgeSupport generator which might already fix this issue, but it's not ready yet for prime time. In the meantime I recommend to wrap the symbols/APIs you need inside an Objective-C class and call it from MacRuby.

Laurent
