   I managed to get Facebook Connect working in my scene, "EndGameScene" which will allow the user to post their score when the game is over. Everything was working perfectly fine until I tried adding FBConnect to the options scene ("Options") as well (allowing the user to logout from that screen). Now, I'm getting this error:

   duplicate symbol _session in /..../Options.o and /..../EndGameScene.o

   This is how the code is laid out:

   MenuScene.h
   #import <UIKit/UIKit.h>
   #import "cocos2d.h"
   #import "FBConnect/FBConnect.h"
   extern FBSession* session;

   EndGameScene.mm
   #import "EndGameScene.h"
   #import "MenuScene.h"
   #import "GameScene.h"
   #import "cocoslive.h"
   FBSession* session;

   Options.mm
   #import "Options.h"
   #import "MenuScene.h"
   FBSession* session;

   In EndGameScene.mm and Options.mm, shouldn't FBSession* session; be declared extern as in MenuScene.h ? (or maybe they shouldn't be declared at all since you import MenuScene.h)

   using extern in both of those files gave me another error upon building, but keeping extern in Options.mm and MenuScene.h, and no extern in EndGameScene.mm seems to have worked.

   thanks!

   Hi,

   I am new at cocos2d framework and trying to implement one new app. But I faced some problem at Facebook connect. I can not understand how can I integrate this api at my app. I added the FBConnect at my apps and import at my app file. When I tried to build it shows 3 errors like "Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.0 failed with exit code 1" and 60 warnings like "warning: implicit conversion shortens 64-bit value into a 32-bit value"

   Please help me how can I integrate the Facebook Connect with my cocosed app.

   Regards;
   Supankar

   try to add a 'f' prefix to the numeric values where those warnings are thrown. Worked for me in a few lib's I added before.
