Hi everyone, I have the same 60 compiler errors on my iphone4s with unity3d version 3.5.5. I tried all of your suggestions, but none of them works for me. I have the right vuforia plugin for IOS. I read in another forum, that vuforia plugin supports only armv7, so I changed it in Unity- and Target- Buildsetting. Same problem. I reinstalled everything several times. When i delete the plugin folder, everything works fine. Has anyone any new idea, what I can try to fix this proplem?
