GDB超级基础教程

为什么叫超级基础呢，因为我被坑了一把....

编译选项带 -g 就可以在可执行程序中加入调试信息，然后就可以使用gdb去查看了。

使用help命令就可以看到:

(gdb) help
List of classes of commands:

aliases -- Aliases of other commands
breakpoints -- Making program stop at certain points
data -- Examining data
files -- Specifying and examining files
internals -- Maintenance commands
obscure -- Obscure features
running -- Running the program
stack -- Examining the stack
status -- Status inquiries
support -- Support facilities
tracepoints -- Tracing of program execution without stopping the program
user-defined -- User-defined commands

Type "help" followed by a class name for a list of commands in that class.
Type "help" followed by command name for full documentation.
Command name abbreviations are allowed if unambiguous.

这里注意一点了，这些不是命令行参数，是一种种类，有需要的话再进入查看，比如输入 help status!!!

常用的gdb命令:
breakpoint
clear
