调试的时候,可以直接在行号后用鼠标点一下来添加断点(如图: 之后“菜单-Debug-Start/Continue”(或直接快捷键F8)即可运行到断点处,单步是F7 以上操作跟VC差不多,接下来是用gdb命令的方法: 启动调试之后,可以在Debugger选项卡的Command框里输命令(如图: 一般调试时最常用的是设置断点,查看变量的值,首先 break funt...

其原理用Visual StudioCode环境下来类比,使用该IDE熟悉的话便知道 发行一个程序的时候,可以有release 版本和 debug版本,只有我们选择debug版本的时候,程序才可以被调试,否则不行。这里也类似,加上-g就相当于生成debug版本的程序,不加就默认是release版本的。
程序的发布方式有两种,debug模式和 release 模式。 Linux gcc/g++出来的二进制程序,默认是release模式。 要使用cgdb调试,必须在源代码生成二进制程序的时候, 加上 -g 选项。 下面是Makefile中的内容,用于自动化编译: 1myexe:code.c2gcc -o $@ $^ -std=...
