简单来说就是在以往的gdb开始的时候添加一个-tui选项.有的版本已经有gdbtui这个程序了
在linux自带的终端里是正常显示的,但是在securecrt里面,可能由于编码的问题,边缘会有些乱码,不过不影响使用(如果你的程序有错误输出,会扰乱整个界面,所以在调试的时候,建议添加2>/dev/null,这样的话基本可用)
启动gdb之后,上面是src窗口,下面是cmd窗口,默认focus在src窗口的,这样的话上下键以及pagedown,pageup都是在移动显示代码,并不显示上下的调试命令.这个时候要切换focus,具体可简单参见
(gdb) info win 查看当前focus SRC (36 lines) <has focus> CMD (18 lines) (gdb) fs next 切换focus Focus set to CMD window. (gdb) info win SRC (36 lines) CMD (18 lines) <has focus> (gdb) fs SRC 切换指定focus Focus set to SRC window. (gdb)
(Window names are case in-sensitive.)
To start in neato and highly-recommended GUI mode, start the debugger with gdb -tui. (For many of the examples, below, I show the output of gdb's dumb terminal mode, but in real life I use TUI mode exclusively.)
And here is a screenshot of what you'll see, approximately:
