vscode_c++环境配置

步骤

  1. 前置物料:

    • 安装 vscode 插件 : c/c++

  2. 安装 mingw-w64 (windows上编译c++的工具). 将并配置 bin 目录到环境变量中

    下载地址: http://mingw-w64.org/doku.php/download/mingw-builds

    如: D:\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin

配置代码提示 c_cpp_properties.json

有安装 vs 的情况下 (推荐)

这种方式可以 stl 库都可以代码提示, mingw-w64 里面的库 则不行

  1. 在 vscode 的配置文件 c_cpp_properties.json 中 include vs的库

        "configurations": [
            {
                "name": "Win32",
                "includePath": [
                    "${workspaceFolder}/**",
                    "C:/my_install/vs2015/VC/include"
                ],

没有安装 vs 的情况下

  1. 查出 mingw-w64 中需要 include 的头文件目录.

    COLLECT_GCC=gcc
    Target: x86_64-w64-mingw32
    ...
    #include <...> search starts here: // 下面那几个目录
    D:/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include
    D:/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include-fixed

    End of search list.

  2. 将这几个 头文件 所在目录丢进 vscode 的配置文件 c_cpp_properties.json 中

                ],

配置 编译 task.json

  1. 在 vscode 的 task.json 中新建一个任务
