我的C ++程序无法在Visual Studio代码上编译 [英] My C++ program won't compile on Visual Studio code

问题描述

我第一次尝试使用Visual Studio Code，但我的C ++无法编译.

I'm attempting to use Visual Studio Code for the first time and my C++ won't compile.

我已经从MSYS2将mingw的bin和bash.exe添加到了我的PATH中.我所有的代码都位于同一目录中，直接来自Microsoft指南 https://code. visualstudio.com/docs/cpp/config-mingw (我确实更改了我的路径).我所有的文件也都在同一个目录中.

I have already added mingw's bin and bash.exe from MSYS2 to my PATH. All of my code is in the same directory and straight from microsoft's guide https://code.visualstudio.com/docs/cpp/config-mingw (I did change the paths to mine). All of my files are also in the same directory.

我已包含文件

helloworld.cpp:

helloworld.cpp:

#include <iostream>


using namespace std;

int main()
{
   cout << "Hello World";
}

task.json:

tasks.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build hello world",
            "type": "shell",
            "command": "g++",
            "args": [
                "-g",
                "-o",
                "helloworld",
                "helloworld.cpp"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

c_cpp_properties.json:

c_cpp_properties.json:

{
    "configurations": [
        {
            "name": "Win32",
            "defines": [
                "_DEBUG",
                "UNICODE"
            ],
            "compilerPath": "C:\\Mingw-w64\\mingw32\\bin\\g++.exe",
            "intelliSenseMode": "gcc-x64",
            "browse": {
                "path": [
                    "${workspaceFolder}"
                ],
                "limitSymbolsToIncludedHeaders": true,
                "databaseFilename": ""
            }
        }
    ],
    "version": 4
}

launch.json:

launch.json:

{
    "version": "0.2.0",
     "configurations": [
         {
             "name": "(gdb) Launch",
             "type": "cppdbg",
             "request": "launch",
             "program": "${workspaceFolder}/helloworld.exe",
             "args": [],
             "stopAtEntry": true,
             "cwd": "${workspaceFolder}",
             "environment": [],
             "externalConsole": false,
             "MIMode": "gdb",
             "miDebuggerPath": "C:\\Mingw-w64\\mingw32\\bin\\gdb.exe",
             "setupCommands": [
                 {
                     "description": "Enable pretty-printing for gdb",
                     "text": "-enable-pretty-printing",
                     "ignoreFailures": true
                 }
             ]
         }
     ]
 }

该文件无法生成，并且我不断出现相同的错误消息:

The file wouldn't build and I am continuously the same error message:

g ++.exe:错误:helloworld.cpp:没有这样的文件或目录g ++.exe: 致命错误:没有输入文件编译终止.终点站 进程终止，退出代码:1

g++.exe: error: helloworld.cpp: No such file or directory g++.exe: fatal error: no input files compilation terminated. The terminal process terminated with exit code: 1

推荐答案

似乎编译器无法找到源文件，更新task.json以编译具有完整路径的程序，

Seems like compiler isn't able to locate the source files , update the tasks.json to compile programs with complete path ,

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build hello world",
            "type": "shell",
            "command": "g++",
            "args": [
                "-g",
                "${file}",//Just
                "-o",//edit
                "${workspaceFolder}\\${fileBasenameNoExtension}"//these
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

此处${file}给出了具有扩展名(.cpp)的文件的完整路径，${workspaceFolder}和${fileBasenameNoExtension}也几乎是不言自明的.

here ${file} gives complete path of the file with extension(.cpp) , ${workspaceFolder} and ${fileBasenameNoExtension} are pretty much self-explanatory too .
