AOT issue with mvvmcross

Question

I'm unable to build Xamarin projects that reference MvvmCross as I receive the error:

Error MT3001: Could not AOT the assembly '/Users/chriskoiak/Documents/Initial/Mobile Clients/xxxx/obj/iPhone/Debug/mtouch-cache/Build/Cirrious.CrossCore.dll' (MT3001) Error MT3001: Could not AOT the assembly '/Users/chriskoiak/Documents/Initial/Mobile Clients/xxxx/obj/iPhone/Debug/mtouch-cache/Build/Cirrious.MvvmCross.dll' (MT3001)

This error occurred after I upgraded to xcode5, mvvmcross 3.0.12 Xamarin.iOS 7.0.0.11

Has anyone else experienced this problem or can suggest a fix?

Thanks

It's an AOT compiler error message from a release of xamarin.ios in the last few hours - try their support email — Stuart, Sep 19 '13 at 16:17

This is a little bug that has appeared in the initial Xamarin.iOS 7 release, caused by the transition to "real" PCL reference assemblies on OS X. The developers are working to get this fixed right away, but in the meantime there is a work-around. Specifically, you can add -linkskip=System.Net -linkskip=System.Windows to the "Additional mtouch arguments" under Project Options -> Build -> iOS Build. This will tell the linker not to try to link System.Net or System.Windows.

Update: A corrected version of Xamarin.iOS (7.0.1) has now been released to the alpha channel. When using this latest version, the linksip work-around should no longer be needed.

Thanks for the info, but your link leads to an angry "Access Denied" page! – Matt Burland Sep 19 '13 at 17:35
Also `-linkskip` seems to have fix it for me! Thanks! – Matt Burland Sep 19 '13 at 17:43
Not for me, the link to System.Windows seem to have been broken so ICommand is not recognized anymore. Then in iOS the lambda's on ICommands cannot be converted to strings anymore.... More digging :( – Hugo Logmans Sep 19 '13 at 18:38

Hugo - remember to reference the System.Windows assembly as described here http://slodge.blogspot.co.uk/2013/09/3012-pushed-to-mvvmcross-binaries-not.html – Chris Koiak Sep 19 '13 at 18:58
Glad this is working for you guys! @MattBurland thanks for the heads-up on the bad link. I removed it. In any case, a note about the fix should appear in the release notes for the next version. – Brendan Zagaeski Sep 19 '13 at 19:18
@HugoLogmans Maybe you're also hitting [this one](http://stackoverflow.com/questions/18901310/tinyioc-xamarin-ios-linker-settings)? – Brendan Zagaeski Sep 19 '13 at 21:50
@Brendan: looks like it, but didn't help. – Hugo Logmans Sep 20 '13 at 07:13
This issue has now been resolved with the latest release of Xamarin.iOS – Chris Koiak Oct 01 '13 at 20:59
