GDB錯誤值無法轉換爲整數

我想調試一些應用程序，我想通過一些數據使用以下命令，但我得到錯誤。GDB錯誤值無法轉換爲整數

.... 
    .... 
    (gdb) x/20x $esp 
    Value can't be converted to integer. 
    (gdb)

我的GDB版本跟隨着：

也許你的CPU不具備ESP寄存器（$ ESP）？試試'info registers'，你看到了什麼？ – fork0 2012-07-25 20:07:14

我只是想出了..你搖滾！ – Satish 2012-07-25 20:15:07

(gdb) x/20x $esp
Value can't be converted to integer.

嘗試x/20x $rsp或x/20x $sp

你[R從64位系統統一它，所以你應該使用寄存器名稱作爲rip而不是eip等所有寄存器。

例如：

 
(gdb) x/x $rip 
0x4004c8 : 0x4005d8b8
