编译和调试

本地系统是windows,远程服务器是Linux,如何远程编译和调试服务器端的c/c++程序?一种比较好的方式是:vs code + remote tools + CMake

1 安装VS CODE

2 在本地的VS CODE安装remote - SSH插件

3 通过remote-ssh远程连接到服务器,然后在远程服务器上的VS CODE安装如下插件:

4 打开远程服务器上的文件夹菜单”File”->”Open Folder”,选择test,单击”OK”

5 添加源文件在test新建一个文件”main.c”,如下:

#include int main(int argc, char *argv[]){ printf("Hello world!\n"); return 0;}

6 添加CMakeLists.txt文件在test中添加CMakeLists.txt文件,如下:

cmake_minimum_required(VERSION 2.6)project(test_cmake)set(CMAKE_CXX_FLAGS, "${CMAKE_CXX_FLAGS} -g") #debugset(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR})add_executable(test_cmake main.cc)

左侧side bar底部多出了一个CMake, 单击它切换到CMake。左侧side bar如果没有CMake,可在side bar上右键单击,在弹出菜单中勾选CMake。

单击该右侧的Configuation(配置所有项目)按钮,等待配置完毕。在该窗口出现了test_cmake…

切换到explorer, 发现多了build文件夹,展开build,发现多了很多文件,但是还没生成文件test_cmake

切换到CMake, 点击build此时再去build目录,发现生成了test_cmake文件。

7 状态栏CMake ToolCMake:Select a kit如上图,vs code的底部状态栏,第5个区域显示的是”No Kit Selected”,表示没有选择 CMake kit,单击该项,或者F1,CMake:Select a kit. select a kit

8 create a launch.json file单击左侧的dubug, click “create a launch.json file”, or click key F5

select environment

select a configuration

then a file “launch.json” is created in folder “.vscode”, make some change as below:

{ // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "name": "g++-7 build and debug active file", "type": "cppdbg", "request": "launch", "program": "${command:cmake.launchTargetPath}", //modify "args": [], "stopAtEntry": false, "cwd": "${workspaceFolder}", "environment": [], "externalConsole": false, "MIMode": "gdb", "setupCommands": [ { "description": "Enable pretty-printing for gdb", "text": "-enable-pretty-printing", "ignoreFailures": true } ], "preLaunchTask": "g++ test", //the task label in task.json "miDebuggerPath": "/usr/bin/gdb" } ]}

9 create a file task.json按F5,弹出提示框,选择”Configure Task”then a file “task.json” is created in folder “.vscode”, make some change as below:

{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "type": "shell", "label": "g++ test", "command": "cmake --build ${workspaceFolder}/build --config Debug --target all -- -j 50", "args": [], "options": { "cwd": "/usr/bin" }, "problemMatcher": [ "$gcc" ], "group": "build" } ]}

编译和调试

编译 快捷键:F7调试 快捷键:F5如果断点无效,就删除上述非源文件,从第6步开始,重新做一遍即可。
