VS Code不会使用多个.ccp源文件构建c ++程序

请注意，我在Ubuntu 17.10上使用VS Code，并使用GCC编译器。

我在构建使用其他.ccp文件的简单程序时遇到了麻烦。我可能在这里缺少明显的东西，因为我对编程还不熟悉，但是我将解释到目前为止的工作。这使我无法继续学习我正在做的教程。

我编写了一个非常简单的程序来说明我的观点，如下所示。

main.ccp

#include <iostream>
#include "Cat.h"
using namespace std;
int main ()
{
speak();
return 0;
}

Cat.h

#pragma once
void speak();

Cat.ccp

#include <iostream>
#include "Cat.h"
using namespace std;
void speak()
{
std::cout << "Meow!!" << std::endl;
}

这个简单的程序在Codeblocks和Visual Studio Community

2017中均内置，没问题，我不知道要使其运行需要做什么。底部的此错误表明根本没有拾取Cat.ccp文件。如果要将定义从此Cat.ccp放到头文件中，则程序可以编译并运行良好，但是我需要利用该.ccp文件，因为我了解这是公认的分离代码的方法。我会注意到所有文件也都在同一文件夹中。

我知道我可能需要告诉VS

Code在哪里寻找Cat.ccp文件，但是对我来说很奇怪，它在同一位置找到了标头。不过，在网上查看后，我一直在阅读，我可能需要在c_cpp_intellisense_properties.json中放置一个目录。这是我的样子。

{ "configurations": [ { "name": "Mac", "includePath": [ "/usr/include", "/usr/local/include", "${workspaceRoot}" ], "defines": [], "intelliSenseMode": "clang-x64", "browse": { "path": [ "/usr/include", "/usr/local/include", "${workspaceRoot}" ], "limitSymbolsToIncludedHeaders": true, "databaseFilename": "" }, "macFrameworkPath": [ "/System/Library/Frameworks", "/Library/Frameworks" ] }, { "name": "Linux", "includePath": [ "/usr/include/c++/7", "/usr/include/x86_64-linux-gnu/c++/7", "/usr/include/c++/7/backward", "/usr/lib/gcc/x86_64-linux-gnu/7/include", "/usr/local/include", "/usr/lib/gcc/x86_64-linux-gnu/7/include-fixed", "/usr/include/x86_64-linux-gnu", "/usr/include", "/home/danny/Documents/C++_Projects/24_-_Classes/Cat.cpp", "${workspaceRoot}", "/home/danny/Documents/C++_Projects/24_-_Classes/", "/home/danny/Documents/C++_Projects/24_-_Classes/.vscode", "/home/danny/Documents/C++_Projects/24_-_Classes/.vscode/Cat.cpp" ], "defines": [], "intelliSenseMode": "clang-x64", "browse": { "path": [ "/usr/include/c++/7", "/usr/include/x86_64-linux-gnu/c++/7", "/usr/include/c++/7/backward", "/usr/lib/gcc/x86_64-linux-gnu/7/include", "/usr/local/include", "/usr/lib/gcc/x86_64-linux-gnu/7/include-fixed", "/usr/include/x86_64-linux-gnu", "/usr/include", "${workspaceRoot}", "/home/danny/Documents/C++_Projects/24_-_Classes/", "/home/danny/Documents/C++_Projects/24_-_Classes/.vscode/Cat.cpp" ], "limitSymbolsToIncludedHeaders": true, "databaseFilename": "" } }, { "name": "Win32", "includePath": [ "C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/include", "${workspaceRoot}" ], "defines": [ "_DEBUG", "UNICODE" ], "intelliSenseMode": "msvc-x64", "browse": { "path": [ "C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/include/*", "${workspaceRoot}" ], "limitSymbolsToIncludedHeaders": true, "databaseFilename": "" } } ], "version": 3 }

有一次，我在想，如果我需要在里面加上一个双指令告诉编译器建立在两个.ccp文件 tasks.json

但我没有设法弄清楚如何做到这一点，或者即使这是正确的方法。

task.json

{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "label": "Build", "type": "shell", "command": "g++ -g /home/danny/Documents/C++_Projects/24_-_Classes/main.cpp -o Classes", "group": { "kind": "build", "isDefault": true }, "problemMatcher":"$gcc" } ] }

感谢任何帮助。而且，以防万一您想知道，我之所以不只是在Codeblocks或VSCommunity中完成本教程，是因为我想知道大多数情况下发生了什么。另外，我想让VS Code为我工作，因为到目前为止效果很好。
