Unity Plugin:

Hey all. I can't get my plugin to work with Unity on Ubuntu 14.04.

My plugin code:

main.h

Code (csharp):

1.  
2. #include <stdio.h>
3.  
4. extern "C" {
5.     extern void gameInit();
6.     extern int PrintANumber();
7. }
8.  

main.cpp

Code (csharp):

1.  
2. #include <stdio.h>
3. #include "main.h"
4. extern "C" {
5.     void gameInit()
6.     {
7.         puts("GAME INITIALIZED!!!");
8.         return;
9.     }
10.     int PrintANumber(){
11.         return 5;
12.     }
13. }
14.  

I compile it with
g++ -c -Wall -fPIC main.cpp
g++ -shared -o libaigame.so main.o
cp libaigame.so /media/progmaster/563C80473C8023D9/Unity/PortalAIL/Assets/Plugins/

My Unity code is as follows:

Code (csharp):

1.  
2. [DllImport("aigame")]
3. public static extern void gameInit();
4. [DllImport ("aigame")]
5. private static extern int PrintANumber();
6.  
7. void Start ()
8. {
9.     Debug.Log (PrintANumber ());
10.     //gameInit ();
11. }
12.  

And it gives me an error:
EntryPointNotFoundException: PrintANumber
Main.Start () (at Assets/Main.cs:30)

Can you help me?

 

Solved by installing Eclipse C++ and modifying the plugin example code.
