objective c - detected an attempt to call a symbol in system libraries that is not present on the iPhone -

-

im using x-code 3.2.4 , i'm using ios4.1 sdk.

i'm getting following error when try call "extaudiofileopenurl" audio toolbox.

detected attempt call symbol in system libraries not present on iphone: _unwind_resume called function _zn15id3parserhandlec2epvpfls0_mmmps0_pme in image audiotoolbox.

why happening , how can fix it?

thanks, db.

edit

in addition when running on 4.1 device error "error: 805297555"

what hell?

the exact line of code causing problem this.

// open audio file , associate extended audio file object.          osstatus result= extaudiofileopenurl (sourceurlarray[audiofile], &audiofileobject);

it's straight out of sample code project. sample code project runs fine.

i don't understand why if start new project same code errors.

this means extaudiofileopenurl unsupported api on iphone. extaudiofileopenurl makes use of exception handling api not available on iphone, why seing sympton of underlying error.
