本文利用Dev-C++中现有的编译器,来配置VS Code的C++运行环境,并支持C++11。
将编译器添加到环境中
找到Dev-C++中的MinGW64编译器的位置,通常位置为
D:\Program Files (x86)\Dev-Cpp\MinGW64
打开系统的环境变量设置,打开用户变量的Path,添加 D:\Program Files (x86)\Dev-Cpp\MinGW64\bin
打开cmd,输入 gcc -v
来检测是否加入成功,如果添加失败,会输出
'gcc' 不是内部或外部命令,也不是可运行的程序或批处理文件。
添加成功后,在cmd中输入 gcc -v -E -x c++ -
来获取链接文件的地址,在cmd输出的结尾,能看到7行路径,保存下来这7行路径待会需要用到。
配置VS Code
VS Code 安装C/C++
, code runner
拓展
在VScode中打开一个工作文件夹,文件夹目录需要全英文且无特殊符号
打开后会在左侧文件夹中找到一个名叫 .vscode
的文件夹,打开里面的三个文件:launch.json
、tasks.json
、c_cpp_properties.json
。注意要修改路径
launch.json

}
c_cpp_properties.json
在这个文件中,需要填写之前从cmd中得到的7行路径。
{
"configurations": [
{
"name": "Win32",
"includePath": [
"${workspaceFolder}/**",

"cStandard": "c99",
"cppStandard": "c++11",
"intelliSenseMode": "gcc-x64"
}
],
"version": 4
}
保存成功后,编写一个程序并保存在工作文件夹下,按下 F5
编译运行,注意文件名不能出现中文!
运行后闪退的解决
上面的 launch.json
中是通过直接启动编译器生成的.exe文件来运行的,运行结束后程序会立刻退出。这里可以利用cmd来运行生成的.exe文件并添加上 pause
,使得程序运行结束后不会立刻退出。
将 launch.json
修改为以下内容:
{
"version": "0.2.0",
"configurations": [
{
"name": "(gdb) 启动",
"type": "cppdbg",
"request": "launch",
"program": "C:\\Windows\\system32\\cmd.exe",
"args": [
"/C",
"${fileDirname}\\${fileBasenameNoExtension}.exe",
"&",
"pause"
],
"stopAtEntry": false,
"cwd": "${fileDirname}",//指默认文件操作的目录(如fopen的默认寻找位置),${fileDirname}是C/C++文件的目录,修改为${workspaceFolder}就是工作文件夹目录
"environment": [],
"externalConsole": true,
"MIMode": "gdb",
"miDebuggerPath": "D:/Program Files (x86)/Dev-Cpp/MinGW64/bin/gdb.exe",//把这个路径改成自己电脑的gdb.exe路径
"setupCommands": [
{
"description": "为 gdb 启用整齐打印",
"text": "-enable-pretty-printing",
"ignoreFailures": true
},
{
"description": "将反汇编风格设置为 Intel",
"text": "-gdb-set disassembly-flavor intel",
"ignoreFailures": true
}
],
"preLaunchTask": "C/C++: gcc.exe 生成活动文件"
}
]
}
然后再运行程序,程序运行结束后会出现 请按任意键继续. . .
程序输出中文时乱码的解决
因为控制台所用的编码为GBK,而VS Code所使用的编码为UTF-8,两者编码不一致导致的中文输出乱码。
这里将VS Code所使用的编码改为GBK,与控制台保持一致即可。
在VS Code中按 Ctrl+Shift+P
,输入 user
,点击 打开用户设置
,在打开界面的最上方的搜索栏里输入 encoding
,在界面里的下拉框中选择 Simplified Chinese (GBK)
即可。
对于已打开的文件,在文件的右下角点击 UTF-8
,在上方的弹出框中选择 通过编码重新打开
, 选择 Simplified Chinese (GBK)
,这时文件里所有的中文都会变成乱码,删除再重新输入即可。
然后再运行程序,程序将正常输出中文。
