GDB：lx-symbols未定义的命令 [英] GDB: lx-symbols undefined command

问题描述

我遵循以下指南：
https：/ /www.kernel.org/doc/Documentation/gdb-kernel-debugging.txt

当我尝试使用以下命令加载模块符号时：
（gdb）lx-symbols

gdb表示该命令未定义。我如何将这些helper命令添加到gdb中？

gdb info：gdb-7.6.1-51.el7.x86-64在Centos 7.0上

解决方案

您必须获取最新的内核源代码（可能是4.0-rc4）或者将补丁。基本上看看你是否有 script / gdb / 目录，比如这个在你的内核源代码中。因为那是你获得这些脚本的地方。

然后你按照 gdb-kernel-debugging.txtrel =nofollow> https://www.kernel.org/doc/Documentation/gdb-kernel-debugging.txt

I am following the guide below: https://www.kernel.org/doc/Documentation/gdb-kernel-debugging.txt

When I try to load the module symbols using the command below: (gdb) lx-symbols

gdb says that the command is undefined. How do I add these helper command to gdb?

gdb info: gdb-7.6.1-51.el7.x86-64 on Centos 7.0

解决方案

You have to get the latest kernel sources (may be 4.0-rc4) or backport the patch. Basically see if you have script/gdb/ directory like this in your kernel sources. Because that is where you get these scripts.

Then you follow the steps mentioned in https://www.kernel.org/doc/Documentation/gdb-kernel-debugging.txt
