cocos2d iphone - Xcode: sigABRT in alcMakeContextCurrent -


i fiddling around trying game center leaderboards work. after becoming frustrated, removed code added. however, stuck error, though deleted it! feels ruined finished game.

specifically, here when error occurred: 1) using cocos2d. 2) copy , pasted gkauthentication project, imported .h first cocos2d scene. 3) got sigabrt error, , decided remove import. however, error persisted. 4) removed gkauthentication files project completely. however, error still persists.

+ (bool) makecontextcurrent:(alccontext*) context devicereference:(alcdevice*) devicereference {     @synchronized(self)     {         if(!alcmakecontextcurrent(context)) //sigabrt occurs here         {             if(nil != devicereference)             {                 check_alc_call(devicereference);             }             else             {                 oal_log_error(@"could not make context %p current.  pass in device reference better diagnostic info.", context);             }             return no;         }     }     return yes; }

strange thing: simulator causes error, on phone works great.

it apparently has audio (?!). have no idea gkauthentication has this. seems sudden error. here error message console:

cocos2d: gl supports discard_framebuffer: yes cocos2d: gl supports shareable vao: no audiostreambasicdescription:  2 ch,  44100 hz, 'lpcm' (0x00000029) 32-bit little-endian float, deinterleaved 2014-03-10 15:04:43.058 gaui[40423:907]  <com.apple.main-thread> start: mach message timeout. apparently deadlocked. aborting now. (lldb)

i had same issue mac book pro , mac mini, rebooting computer solves problem.
