GDK8上面也可以运行安卓系统，给喜欢调试安卓的同学提供了便利的研究条件。

安装gdb-multiarch

sudo apt install gdb-multiarch

设置环境变量

右键此电脑，点击属性，再点击高级系统设置

进入系统属性后，点击环境变量->选中PATH->点击编辑->点击新建->添加adb->点击确定

输入adb version，查看环境变量是否设置正确（能输出版本信息即可）。

启用开发者模式及调试模式

设置->关于设备->连续点击版本号->进入开发者模式
设置->更多设置->开发者选项->调试->网络ADB调试

建立ADB调试连接

查看GDK8的IP地址：设置->关于设备->IP地址
输入adb connect IP地址，端口号默认是5555

输入adb shell，即可进入GDK8内；输入su提升至管理员权限

GDK8的安卓上面自带了GDBServer。在命令行内输入gdbserver，就可以看到帮助信息

开始远程调试

新开一个命令行作为主机端；刚才的命令行作为目标端
主机端内输入 adb forward tcp:6000 tcp:6000
目的是将主机上的6000号端口的通信数据重定向到目标端的6000号端口上

目标端内输入gdbserver :6000 –attach 3438

主机端内输入gdb，再输入target remote :6000

警告

产生下方警告的原因有两个：

  1. 需要GDB-MulitArch
    原本的GDB输入set architecture 找不到arm架构->应该使用GDB-MulitArch
  2. 主机端的GDB要和目标端的GDBServer版本相互匹配

安装完GDB-MultiArch后重新尝试
