VSCode - C++ 未定义对“CLASS::FUNCTION"的引用 [英] VSCode - C++ undefined reference to 'CLASS::FUNCTION'

问题描述

我正在使用 VSCode 创建一个 C++ 项目，并在尝试构建 && 时不断收到此错误.调试.从控制台运行时，如果我使用 'g++ -o main 'main.cpp' 'file_1.cpp' 'file_2.cpp'' 它可以正常工作并正确编译.

I'm using VSCode to create a C++ project and keep getting this error when trying to build && debug. When running from console if I use 'g++ -o main 'main.cpp' 'file_1.cpp' 'file_2.cpp'' it works and compiles correctly.

我读到这与文件链接有关?有谁知道如何在 VSCode 中解决这个问题?如果有帮助，我有一个默认的 launch.json 配置文件来构建活动文件.

I have read that this is something to do with the linking of files? Does anyone know how to fix this in VSCode? I have a default launch.json configuration file that builds the active file if this helps.

这是我的 tasks.json 文件的内容:

Here is the contents of my tasks.json file:

{
"version": "2.0.0",
"tasks": [
    {
        "type": "shell",
        "label": "shell: g++ build active file",
        "command": "/usr/bin/g++",
        "args": [
            "-g",
            "${file}",
            "-o",
            "${fileDirname}/${fileBasenameNoExtension}"
        ],
        "options": {
            "cwd": "/usr/bin"
        },
        "problemMatcher": [
            "$gcc"
        ],
        "group": {
            "kind": "build",
            "isDefault": true
        }
    },
    {
        "type": "shell",
        "label": "g++ build active file",
        "command": "/usr/bin/g++",
        "args": [
            "-g",
            "${file}",
            "-o",
            "${fileDirname}/${fileBasenameNoExtension}"
        ],
        "options": {
            "cwd": "/usr/bin"
        }
    }
]

}

我使用的是 Debian 10 'Buster'

推荐答案

您需要修改 tasks.json 以编译所有 .cpp .在 args 中，将 ${file} 更改为 ${workspaceFolder}/*.cpp要运行构建任务，请按 Ctrl+Shift+B，这将在当前目录中生成一个执行文件.在终端中执行此文件以运行程序(./fileName)

You need to modify tasks.json for compile all .cpp . In args change ${file} for ${workspaceFolder}/*.cpp To run the build task press Ctrl+Shift+B, this generate a execution file in the current directory. Execute this file in the terminal for run the program (./fileName)
