Visual Studio 代码，#include <stdio.h>说“向设置添

Visual Studio Code, #include lt;stdio.hgt; saying quot;Add include path to settingsquot;(Visual Studio 代码，#include stdio.h说“向设置添加包含路径)

问题描述

我正在尝试在 Visual Studio Code 中构建 C/C++.我安装了 C/C++ 和所有相关的扩展.

#include int main() {printf("现在测试C
");返回0；}

但是在 #include <stdio.h> 下有一条绿线，上面写着向设置添加包含路径".当我点击它时，它会移动到c_cpp_properties.json".

我如何以及在哪里可以在下面的配置中添加包含路径?

配置":[{"name": "Mac","includePath": ["/usr/include"]}]

对这种情况的最新看法.2018 年，C++ 扩展在配置中添加了另一个选项 c_cpp_properties.json文件的>compilerPath；

配置":[{名称":Mac"，includePath":[/usr/local/include"，/path/to/additional/includes",/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include"]}]

<代码>{版本":0.1.0"，isShellCommand":真，taskName":GenericBuild"，showOutput":总是"，命令":sh"，suppressTaskName":假，"args": ["-c", "clang++ -std=c++14 -Wall -Wextra -pedantic -pthread "${file}";&&./a.out"]}

<代码>{版本":0.1.0"，isShellCommand":真，taskName":GenericBuild"，showOutput":总是"，命令":sh"，suppressTaskName":假，args":[-c"，clang -std=c11 -Wall -Wextra -pedantic -pthread "${file}";&&./a.out"]//命令参数...}

I'm trying to build C/C++ in Visual Studio Code. I installed C/C++ and all the relevant extensions.

#include <stdio.h>
int main() {
    printf("Test C now
");
    return 0;
}

But there's a green line under #include <stdio.h> saying "Add include path to settings". When I click it, it moves over to "c_cpp_properties.json".

How and where can I add include paths in the configurations below?

"configurations": [
    {
        "name": "Mac",
        "includePath": ["/usr/include"]
    }
]

A more current take on the situation. During 2018, the C++ extension added another option to the configuration compilerPath of the c_cpp_properties.json file;

compilerPath (optional) The absolute path to the compiler you use to build your project. The extension will query the compiler to determine the system include paths and default defines to use for IntelliSense.

If used, the includePath would not be needed since the IntelliSense will use the compiler to figure out the system include paths.

Originally,

How and where can I add include paths in the configurations below?

The list is a string array, hence adding an include path would look something like;

"configurations": [
    {
        "name": "Mac",
        "includePath": ["/usr/local/include",
            "/path/to/additional/includes",
            "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include"
        ]
    }
]

Source; cpptools blog 31 March 2016.

The linked source has a gif showing the format for the Win32 configuration, but the same applies to the others.

The above sample includes the SDK (OSX 10.11) path if Xcode is installed.

Note I find it can take a while to update once the include path has been changed.

The cpptools extension can be found here.

Further documentation (from Microsoft) on the C++ language support in VSCode can be found here.

For the sake of preservation (from the discussion), the following are basic snippets for the contents of the tasks.json file to compile and execute either a C++ file, or a C file. They allow for spaces in the file name (requires escaping the additional quotes in the json using "). The shell is used as the runner, thus allowing the compilation (clang...) and the execution (&& ./a.out) of the program. It also assumes that the tasks.json "lives" in the local workspace (under the directory .vscode). Further task.json details, such as supported variables etc. can be found here.

For C++;

{ 
    "version": "0.1.0", 
    "isShellCommand": true, 
    "taskName": "GenericBuild", 
    "showOutput": "always", 
    "command": "sh", 
    "suppressTaskName": false, 
    "args": ["-c", "clang++ -std=c++14 -Wall -Wextra -pedantic -pthread "${file}" && ./a.out"]
}

For C;

{ 
    "version": "0.1.0", 
    "isShellCommand": true, 
    "taskName": "GenericBuild", 
    "showOutput": "always", 
    "command": "sh", 
    "suppressTaskName": false, 
    "args": ["-c", "clang -std=c11 -Wall -Wextra -pedantic -pthread "${file}" && ./a.out"] // command arguments... 
}
