Help/Support GNU Debugger (gdb) Problem

[MarcelRe 0 12 10.1.1]

Hey guys

I'm facing a problem while using gdb in mTerminal. I tried literally everything but it doesn't work. I'm using gdb from the cydia.radare.org repo and I tried several methods to fix the problem. 

When I want to type in the command:

gdb /var/containers/Bundle/Application/AA7380C2-....3970/Spotify.app/Spotify 

it shows me the following error:

....not in executable format: File format not recognized.

But I don't know why it doesn't recognize the File format.

 

 

Thank you for any help

You need to crack app first.

 

Install app from itunes

install Rasticrac from cydia
