使用cdb调试c ++程序时如何设置断点和显示源代码？ [英] how to set breakpoint and show source code when using cdb to debug c++ programs?

问题描述

为什么bp主要失败？
如何将源代码列为gdb的list命令？

这个问题不一样用于根据行设置断点的CDB命令数字

似乎cdb可以用于windbg，但是可以使用cdb有点类似于gdb吗？

解决方案

cdb允许3个不同的命令设置断点：$ b​​ $ b bp，bm和bu

1. bp接受数字地址的参数


2. bm接受在已加载的模块中是文本符号的参数


3. bu接受可能或可能不加载的模块中的文本符号的参数。

要设置主要的断点，我们可以猜测Image00390000实际上是hello.exe（有时cdb无法恢复你所期望的名称）。您可以使用以下命令：

  bm Image00390000！main 
  

这假设main真的是符号名，加载了符号。您可以使用：

  lmvm Image00390000 //检查符号是否加载
x Image00390000！* main * // lists所有符号，主要在名称
  

why bp main failed? how to list source code as gdb's list command does?

this question is not the same as CDB command for setting a breakpoint based on a line number

seems cdb can be used with windbg, but is that possible to use cdb a bit similar to gdb?

解决方案

cdb allows 3 different commands to set breakpoints: bp, bm, and bu

1. bp accepts arguments that are numeric addresses
2. bm accepts arguments that are textual symbols in a module that is already loaded
3. bu accepts arguments that are textual symbols in modules that may or may not be loaded yet.

To Set a breakpoint at main we can guess Image00390000 is actually hello.exe (Sometimes cdb fails to recover the name you would expect). You can use the command:

bm Image00390000!main

This assumes that main really is the symbol name, and that symbols are loaded. You can use:

lmvm Image00390000 //to check if symbols are loaded
x Image00390000!*main* //lists all symbols that have main anywhere in the name
