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

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；

compilerPath(可选)用于构建项目的编译器的绝对路径.该扩展将查询编译器以确定用于 IntelliSense 的系统包含路径和默认定义.

如果使用，则不需要 includePath，因为 IntelliSense 将使用编译器找出系统包含路径.

原来，

我如何以及在哪里可以在下面的配置中添加包含路径?

列表是一个字符串数组，因此添加一个包含路径看起来像;

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"]}]

链接的源有一个 gif，显示了 Win32 配置的格式，但同样适用于其他配置.

如果安装了 Xcode，上面的示例包括 SDK (OSX 10.11) 路径.

注意我发现更改包含路径后可能需要一段时间才能更新.

cpptools 扩展可以在在这里找到.

有关 VSCode 中 C++ 语言支持的更多文档(来自 Microsoft)可以在此处找到.

为了保存(来自讨论)，以下是tasks.json文件内容的基本片段，用于编译和执行C++文件或C文件.它们允许文件名中有空格(需要使用 " 转义 json 中的额外引号).shell 被用作作为运行器，从而允许编译(clang...)和程序的执行 (&& ./a.out).它还假定tasks.json存在".在本地工作区中(在目录 .vscode 下).更多 task.json 详细信息，例如支持的变量等，可以在此处找到.>

对于 C++；

<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"]}

对于 C;

<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... 
}
