Help/Support GDB Help

NitroxicDemon · February 13, 2015

I am using GDB on iPad Air iOS 81.2 and I see this line

Unrecognized osabi 0 in arm_set_osabi_from_host_info

What does it mean? And when I was debugging a game and wrote continue I got the same error. Any solutions?

It doesn't prevent me from doing anything, I am just wondering why it's there.

There is this one app I am debugging and when I get the value from iGameGuardian and type watch 0x"TheAddress" then c, the app still stays frozen. Sometimes it unfreezes and then freezes again and does not display the value in IDA. Even when I type display/i$pc

I have the same problem on my iPad Mini. Although gdb works fine on the iPhone 5s.

Yup! :thumbsup:

@ if you want gdb to work on an a7 device, you need to have the following tools installed:

Vi IMproved
rsync
SQLite 3.x
Git
GNU Debugger (GDB)
and libgcc

Another question, whats the difference between breakpoints and watchpoints?
