Help/Support GDB Error

A Stick · June 23, 2016

Im not sure what the problem is. Im on iOS 9 iPad and when I try to ssh into the iPad, its fine but when I run gdb I get this error.

warning: Unrecognized osabi 0 in arm_set_osabi_from_host_info

And then when I try to att blackops I get this error.

warning: error on line 221 of "/Volumes/Builds2/BuildRoot/SourceCache/gdb/gdb-1708/src/gdb/macosx/macosx-nat-infthread.c" in function "kern_return_t modify_trace_bit(thread_t, int)": (os/kern) invalid argument (0x4x)

When I type continue or c I get this error.

warning: Unrecognized osabi 0 in arm_set_osabi_from_host_info

What am I doing wrong? How can I fix this so I can mod Call of Duty Black Ops Zombies?

The first 3 are no errors, the last one is.

Does the app continue?

Where did you download GDB from?

Well the last error happens with every command like set. I installed gnu debugger from the correct source and the app does not continue. I have to quit in order for it to unfreeze.
