Problem binding library

Matteo Polito-2

Hi guys, I've a problem on binding GameCircle library by Amazon. They offer the Unity plugin for they library, I want to use classes they made for Unity on Monotouch. I've extracted unity plugin and now I want to use it on Monotouch. I've created a project and hosted it on GitHub (https://github.com/mapo80/GameCircle.Monotouch).

There are two libraries: - AmazonInsightsSDK.a - GameCircle.a

I'm using this linkWith parameters: [assembly: LinkWith ("AmazonInsightsSDK.a", LinkTarget.ArmV7 | LinkTarget.ArmV7s | LinkTarget.Simulator, ForceLoad = true, IsCxx = true, LinkerFlags="-lsqlite3.0 -lstdc++", Frameworks = "AdSupport GameKit MessageUI CoreTelephony SystemConfiguration Security ExternalAccessory Foundation")]

[assembly: LinkWith ("GameCircle.a", LinkTarget.Simulator | LinkTarget.ArmV7 | LinkTarget.ArmV7s, ForceLoad = true, IsCxx = true, LinkerFlags="-lsqlite3.0 -lstdc++", Frameworks = "AdSupport GameKit MessageUI CoreTelephony SystemConfiguration Security ExternalAccessory Foundation")]

When I reference dll on my iOS projects I obtain these errors:

Please review the build log.

Any help? What to do?

Thanks
