为调试编译代码(Compiling Code for Debugging) 为了使 gdb 正常工作, 你必须使你的程序在编译时包含调试信息. 调试信息包含你程序里的每个变量的类型和在可执行文件里的地址映射以及源代码的行号. gdb 利用这些信息使源代码和机器码相关联. 在编译时用 -g 选项打开调试选项. gdb 基本命令 gdb 支持很多的命令使...

The first thing to understand is that commands can only be entered into GDB when the debugging process is stopped, which is done via breakpoints. If you hit a breakpoint, the debug console will look as follows: Notice the(gdb)prompt, politely waiting your input. No better place to start ...
1.3 常规命令表格 2. 基本命令 (Basic Commands) 2.1 启动GDB (Starting GDB) GDB的启动是我们进入调试世界的第一步。启动GDB的最基本方式是在命令行中输入gdb。但通常,我们会带上要调试的程序名称,例如:gdb my_program。 $ gdb my_program 这样,GDB就会加载my_program,准备进行调试。正如庄子在《庄子·逍遥游...

I'll be running the following commands as root, since I'm debugging a tool that needs root access (for now). Substitute non-root and sudo as desired. You also aren't expected to read through all this: I've enumerated each step so you can browse them and find ones of interest. 1....
Enhance the display of gdb: colorize and display disassembly codes, registers, memory information during debugging. Add commands to support debugging and exploit development (for a full list of commands usepeda help): aslr-- Show/set ASLR setting of GDB ...
