vscode如何使用gdb调试
时间:2020-02-12 14:00
1、vscode启动debug窗口 按Ctrl+Shift+D,打开Debug窗口 默认是“No configurations”, 点击“F5”,会提示你配置GDB参数(选择gcc build and debug active file),配置文件名称为launch.json(配置参考3) 配置完成后,再按F5, 会提示配置GCC,选择“Configure Task”, 选择“C/C++: build and debug active file”, 配置文件名称为task.json(配置参考2) 2、GCC配置 “command”: 编译链的地址 3、GDB配置 “program”: 要调试的程序名(包含路径,最好绝对路径,免得麻烦) “miDebuggerServerAddress”: 服务器的地址和端口 “cwd”: 调试程度的路径 “miDebuggerPath”: gdb的路径 4、GDB server编译及运行 1)编译 P53编译时,请打开如下开关; P59需要从编译链目录拷贝一个。 编译完成后的文件如下: 说明: install/bin 目录的mips-linux-gdb为vscode中配置需要的; installgdbserver/bin/ 目录中的mips-linux-gdbserver,需要拷贝到板子中; 2)ssh登录设备,下载gdbserver到/tmp目录中, 并增加+x权限 3)ssh登录设备,下载可执行程序到/tmp目录中, 并增加+x权限 4)运行 备注说明: 5、调试 准备完成, 在VSCode进行调试。 相关推荐:vscode教程 以上就是vscode如何使用gdb调试的详细内容,更多请关注gxlsystem.com其它相关文章!{

GDB运行需要libstdc++.so.6的库,所以需要把此开关打开。
./cool 3 gdb_build
等待完成即可

1) 下载的可执行程序,必须保证是设备所需编译链编译的;
2) vscode中按F5调试时,GCC编译的配置和GDB参考1和2;
