Fedora 29配置 Vscode 出现#include errors detected. Please update your includePath. IntelliSense

问题描述： Linux（此处为Fedora 29）下vscode配置C语言或者C++开发环境后，编写代码，在头文件上有绿色波浪线，并报错#include errors detected. Please update your includePath. IntelliSense features for this translation unit (/home/flanwu/Vscode/C++/test.cpp) will be provided by the Tag Parser.cannot open source file “bits/c++config.h” (dependency of “iostream”)

截图如下

默认c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "gcc-x64"
        }
    ],
    "version": 4
}

在尝试了N多种方法后，基本上都是围绕c_cpp_properties.json文件中库的引用而展开的，我试过后，都没用，最后在千辛万苦的查找后，我怀疑是我文件导入问题，我查看了vscode的官方解决办法，就是下面连接中的，不幸的是，是mac配置

官方解决办法

解决方法：我尝试过，因为C库是在/usr/include/下面，如

于是我尝试添加库来实现

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
            	"/usr/include/",
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "gcc-x64"
        }
    ],
    "version": 4
}

但是仍然没有解决问题。这时候，我冷静想了下，官网的格式有问题？？，库还是没有导入，此时我看到下面"${workspaceFolder}/**"这个，我突然明白了，如果格式相同，应该目录导入是这样的

"/usr/include/**",

而不是这样

"/usr/include/"

更改后，终于解决了问题.

最后附上完整c_cpp_properties.json文件配置

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "/usr/include/**",
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "gcc-x64"
        }
    ],
    "version": 4
}
