Question by Hoffa111 · Feb 20, 2013 at 11:29 AM · dllnotfoundexception

DllNotFoundException in Unity Mobile

Hi, I created a C++ plugin for Unity and I tried to use it in my application. I putting the DLL file into my Unity project's "Plugins" folder. Also i putting dependencies into Unity/Editor folder. But when i run the game (from Editor) I get DllNotFoundException and "License error. Plugins are only supported in Unity Pro!" errors. My Unity version is 4.0 for Mobile. And the most interesting things, when i put the main dll into Unity/Editor folder, the application trows only one error - "License error" and function from dll works fine. Can any one helps me?

The code that I wrote for the C++ is shown in the following:

 #define EXPORT __declspec(dllexport)
 
 #include <stdio.h>
 
 extern "C"
 {
   const EXPORT int DisplayNumber()
   {
     return 42;
   }
 }

C# file:

 [DllImport("TestLib")]
     public static extern int DisplayNumber();
 
     // Use this for initialization
     void Start () 
     {
         print("DLL: " + DisplayNumber());
     }

What mobile platform are you running it on? On iOS, your DLL import path (in the C# file) should be "__Internal". For Android, the path should be whatever the name of the library is.
