Build error in il2cpp 64bit setting with 4.6.1 p5

Hi, this is a known issue that we are currently working on fixing. You can still file a bug report, but we've got some already.

Dear Unity,

We updated Unity to 4.6.2 yesterday, and we still got the same issue. Is this known issue or we did something wrong?

Here is the issue we got. ( pretty same )

Hi!

We just tried to build our game with the 4.6.1 and we add only a single link error on Register_UnityEngine_GameObject_get_networkView();

We don't use any network feature, so I just commented the declarations in UnityICallRegistration.cpp file (commenting void Register_UnityEngine_GameObject_get_networkView(); and Register_UnityEngine_GameObject_get_networkView(); lines)

And it just worked for us!

This property doesn't seem to be stripped, but maybe it's normal. It will not be in the API anymore in Unity 5.x, so I guess that we will not having this link error building with Unity 5.

From the long list of you link errors, I suppose that you really use network code in Unity. If it's true, then you'll have to wait a little bit to be able to build a 64 bit app because it appears that RakNet has not yet been porterd to IL2CPP (as seen in http://blogs.unity3d.com/2015/01/29/unity-4-6-2-ios-64-bit-support/, under "Thnigs to be aware of).

You can also try to build your app without stripping (put Stripping Level to "Disabled" instead of micro-mscorlib).

Cheers
