Getting the code building with M-x compile should be fairly straightforward.<p>For deployment + debugging, you could try this: <a href="https:&#x2F;&#x2F;github.com&#x2F;phonegap&#x2F;ios-deploy" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;phonegap&#x2F;ios-deploy</a><p>Looks like it runs lldb itself, but perhaps with a bit of work you could get it to interact with gud-mode?
