Automate gdb: show backtrace at every call to function puts

gdb

Solution

Try this instead:

set width 0
set height 0
set verbose off
start  # runs to main, so shared libraries are loaded
       # after you reach main, GDB should have libc symbols, "puts" among them
break puts
commands 1
backtrace
continue
end

If this doesn't work, please state operating system version.

EDIT: as osgx correctly points out, the other alternative is to add

set breakpoint pending on

before `break puts`

Problem

I want to debug some program. I need backtraces from all calls to some function, e.g. puts. Now I use such gdb `script`: ``` set width 0 set height 0 set verbose off break puts commands 1 backtrace continue end ``` But starting it with ``` gdb --batch --command=script --args ./some_program arguments ``` Gives a error: ``` Function "puts" not defined. Make breakpoint pending on future shared library load? (y or [n]) [answered N; input not from terminal] /root/script:5: Error in sourced command file: No breakpoint number 1. ``` How can I set breakpoint in script for library call?
