在GDB内,载入程序很简单,使用file命令。如file hello。当然,程序的路径名要正确。 退出GDB === quit 在GDB的命令方式下,输入quit,你就可以退出GDB。你也可以输入'C-d'来退出GDB。 3.运行程序 === run 当你在GDB中已将要调试的程序载入后,你可以用run命令来执行。如果你的程序需要参数,你可以在run指令后...
和LinuxBase Shell习惯一样,对于记不住的命令,可以在输入前几个字母后按Tab补全。 ▪ tbreak temporary breakpoint ▪ rbreak reg-ex breakpoint ▪ break xxx if yyy conditionally break at xxx if condition yyy holds ▪ commands list of commands to be executed when a breakpoint is hit ▪ s...
Type "apropos word" to search for commands related to "word"... Reading symbols from ./hello_server...done. (gdb) Gdb加载成功以后,会显示如下信息: Reading symbols from ./hello_server...done. 即读取符号文件完毕,说明该程序含有调试信息。我们不加 -g 选项再试试:gcc -g -o hello_server2 ...
commands [bnum] ... command-list ... end 为断点号bnum指写一个命令列表。当程序被该断点停住时,gdb会依次运行命令列表中的 命令。 例如: break foo if x>0 commands printf "x is %d\n",x continue end 断点设置在函数foo中,断点条件是x>0,如果程序被断住后,也就是,一旦x的值在foo 函数中大于...

你用的是 target remote 的方式远程debug是吧？ 那么不能用 run，而应该用 continue (c) 开始执行。
