gdb-multiarch + gdbserver调试linux arm应用程序

首先安装gdb-multiarch

sudo apt-get install gdb-multiarch

把编译好的gdbserver发送到板子目录下

查看gdbsever版本

  gdbserver --version

新建程序test.c
test touch test.c

test.c内容

#include 

int main(int argc, char *argv[])
{
	printf("hello,world1!\n");
	printf("hello,world2!\n");
	return 0;
}

编译可执行程序test编译要加-g，在执行程序里面包含调试信息

arm-linux-gnueabihf-gcc test.c -o test

开发板ip 192.168.1.2
ubuntu ip 192.168.1.3

先把ubuntu编译好test程序发给板子
比如调试名为test的可执行程序
板子运行gdbserver 监听，等待ubuntu远程gdb-multiarch 连接
[root@imx6ull:~]# gdbserver 192.168.1.3:1234 test #通信端口设置为1234，也可以设置成其他
Process /root/test created; pid = 374
Listening on port 1234

1、不带tui的gdb-multiarch调试

ubuntu gdb-multiarch 调试test
book@100ask:~/root_fs$ gdb-multiarch test

(gdb) target remote 192.168.1.2:1234 #端口是1234跟gdbserver 一致

这样就可以用gdb命令调试应用程序了。。。

2、下面是带tui的gdb-multiarch调试

-tui表示gdb工具以ui的方式展示。开起来舒服一点。
gdbserver 跟上面一样

[root@imx6ull:~]# gdbserver 192.168.1.3:1234 test #通信端口设置为1234，也可以设置成其他
Process /root/test created; pid = 374
Listening on port 1234

ubuntu gdb-multiarch 调试test
book@100ask:~/root_fs$ gdb-multiarch ui

（gdb）set architecture arm #选择gdb支持的arm架构

（gdb）symbol-file test #test 文件路径 这句话的作用是导入调试文件的符号表

（gdb）target remote 192.168.1.2:1234 #板子ip 92.168.1.2 通信端口1234

这样就可以用gdb命令调试应用程序了。。。
