問題描述

我正在嘗試在 Visual Studio Code 中構(gòu)建 C/C++.我安裝了 C/C++ 和所有相關(guān)的擴展.

#include int main() {printf("現(xiàn)在測試C
");返回0；}

但是在 #include <stdio.h> 下有一條綠線，上面寫著向設(shè)置添加包含路徑".當我點擊它時，它會移動到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徑?

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

對這種情況的最新看法.2018 年，C++ 擴展在配置中添加了另一個選項 c_cpp_properties.json文件的>compilerPath；

compilerPath(可選)用于構(gòu)建項目的編譯器的絕對路徑.該擴展將查詢編譯器以確定用于 IntelliSense 的系統(tǒng)包含路徑和默認定義.

如果使用，則不需要 includePath，因為 IntelliSense 將使用編譯器找出系統(tǒng)包含路徑.

原來，

我如何以及在哪里可以在下面的配置中添加包含路徑?

列表是一個字符串數(shù)組，因此添加一個包含路徑看起來像;

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

鏈接的源有一個 gif，顯示了 Win32 配置的格式，但同樣適用于其他配置.

如果安裝了 Xcode，上面的示例包括 SDK (OSX 10.11) 路徑.

注意我發(fā)現(xiàn)更改包含路徑后可能需要一段時間才能更新.

cpptools 擴展可以在在這里找到.

有關(guān) VSCode 中 C++ 語言支持的更多文檔(來自 Microsoft)可以在此處找到.

為了保存(來自討論)，以下是tasks.json文件內(nèi)容的基本片段，用于編譯和執(zhí)行C++文件或C文件.它們允許文件名中有空格(需要使用 " 轉(zhuǎn)義 json 中的額外引號).shell 被用作作為運行器，從而允許編譯(clang...)和程序的執(zhí)行 (&& ./a.out).它還假定tasks.json存在".在本地工作區(qū)中(在目錄 .vscode 下).更多 task.json 詳細信息，例如支持的變量等，可以在此處找到.>

對于 C++；

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

對于 C;

<代碼>{版本":0.1.0"，isShellCommand":真，taskName":GenericBuild"，showOutput":總是"，命令":sh"，suppressTaskName":假，args":[-c"，clang -std=c11 -Wall -Wextra -pedantic -pthread "${file}";&&./a.out"]//命令參數(shù)...}

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... 
}
