gdb - 自动化 gdb : show backtrace at every call to function puts

Question

我想调试一些程序。我需要对某个函数的所有调用的回溯，例如看跌期权。

现在我使用这样的gdb 脚本:

set width 0
set height 0
set verbose off
break puts
commands 1
backtrace
continue
end

但是从

开始

gdb --batch --command=script --args ./some_program arguments

报错:

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.

如何在库调用的脚本中设置断点？

Answer 1

试试这个:

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

如果这不起作用，请说明操作系统版本。

编辑:正如 osgx 正确指出的那样，另一种选择是添加

set breakpoint pending on

在中断看跌期权之前
