基礎環境配置——VScode 調試C++程序

最近從python要轉向C++，只是簡單的寫一些C++程序，想在VScode上直接用起來，就需要自己手動裝一些插件。寫這篇博客也是因爲安裝的過程中遇到了一些不常見的錯誤，寫下來跟大家分享一下。

1、安裝cpptools插件

這個比較簡單，直接再IDE上點一下，安裝就行。

2、安裝mingw-w64（解決“the file has been downloaded incorrectly”問題）

要自己手動安裝一個for windows 的gcc。 

1、下載mingw-w64 installer

2、如果出現以下問題，嘗試“以管理員身份運行”，如果還解決不了，就看步驟3

3、在https://sourceforge.net/projects/mingw-w64/files/mingw-w64/mingw-w64-release/上下載相應的源碼包：

4、找到（或者解壓）bin目錄，添加到path環境變量。

3、修改launch.json和添加tasks.jason文件

修改launch.json文件

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

添加tasks.json文件

{

    "version": "2.0.0",
    "command": "g++",
    "args": ["-g","${file}","-o","${fileBasenameNoExtension}.exe"],    // 編譯命令參數
    "problemMatcher": {
        "owner": "cpp",
        "fileLocation": ["relative", "${workspaceRoot}"],
        "pattern": {
            "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
            "file": 1,
            "line": 2,
            "column": 3,
            "severity": 4,
            "message": 5
        }
    }
}
