VSCode C/C++ 多文件远程开发 -- gdb

launch.json
lunch.json 用于配置vscode 如何调试程序

tasks.json
指示 vscode 如何编译源码，获得生成文件

c_cpp_properties.json
这文件影响 C/C++ 插件的智能提示，不影响编译，可加可不加。

launch.json

{

    // 悬停以查看现有属性的描述。

request：调试方式，分为launch和attach

program：要调试的程序路径

args：传给调试器的参数

cwd：当前工作目录

MIMode：指示vscode 连接的调试器，lldb 或gdb

stopAtEntry：是否在main 函数入口处停住

preLaunchTask：运行launch.json 要执行的task，与task.json 中的label 对应

task.json

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++-9 生成活动文件",
            "command": "/usr/bin/g++-9",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${workspaceFolder}/*.cpp",
                "-lkuma",
                "-lkev",
                "-lcrypto",
                "-lssl",
                "-lpthread",
                "-ldl",
                "-Bsymbolic",
                "-I${workspaceFolder}/include",
                "-L${workspaceFolder}/lib",
                "-o",        
                "${workspaceFolder}/hello"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "调试器生成的任务。"
        }
    ],
    "version": "2.0.0"
}

label：task 的标签，用来区别不同的task

args：传给g++ 编译器的参数列表，${workspaceFolder}/*.cpp 表示工作目录下的所有cpp 文件，vscode 是不会自动添加链接选项的，需要自己在args 里添加。-o 后面跟的是编译生成的目标文件名。

c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${default}",
                "${workspaceFolder}/include",
                "${workspaceFolder}/include/libkev"
            ],

            "compilerPath": "/usr/bin/clang",
            "cStandard": "c11",
            "cppStandard": "c++14",
            "intelliSenseMode": "linux-clang-x64"
        }
    ],
    "version": 4
}

运行程序，断点成功命中。
