首先安装Gcc
1. 下载
链接 ： https://sourceforge.net/projects/mingw-w64/files/
备用网盘 ： https://pan.baidu.com/s/1trdQtDO6XqmfCbZHc1IDzQ?pwd=nwh5
2. 添加环境变量
3. 创建一个c/c++的文件，随后进入该文件所在文件夹
按住CTRL + ALT + P 进入配置，修改编译器路径
编译器路径：
修改IntelliSense模式：
随后会自动生成.vscode文件，文件下会包含c_cpp_properties.json文件
4. 编译c/c++文件后，会生成tasks.json 文件， 和launch.json 文件（有时需要手动创建）
c_cpp_properties.json

注意事项：
在编译cpp文件的时候，使用g++, 在编译c文件的时候，使用gcc
导入mysql
1. 下载mysql的c++版本
https://dev.mysql.com/downloads/installer/
2. 找到mysql对应的文件目录
example : C:\\Program Files\\MySQL\\MySQL Server 8.0\\include
需要在 c_cpp_properties.json以及tasks.json添加mysql的路径
c_cpp_properties.json
{
"configurations": [
{
"name": "Win32",
"includePath": [
"${workspaceFolder}/**",
"C:\\Program Files\\MySQL\\MySQL Server 8.0\\include"
],
"defines": [
"_DEBUG",
"UNICODE",
"_UNICODE"
],
"windowsSdkVersion": "10.0.19041.0",
"compilerPath": "E:/BaiduNetdiskDownload/x86_64-8.1.0-release-posix-sjlj-rt_v6-rev0/mingw64/bin/g++.exe",
"cStandard": "c17",
"cppStandard": "c++17",
"intelliSenseMode": "windows-gcc-x64"
}
],
"version": 4
}
tasks.json
{
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: cl.exe 生成活动文件",
"command": "cl.exe",
"args": [
"/Zi",
"/EHsc",
"/nologo",
"/Fe${fileDirname}\\${fileBasenameNoExtension}.exe",
"${file}"
],
"options": {
"cwd": "${fileDirname}"
},
"problemMatcher": [
"$msCompile"
],
"group": "build",
"detail": "调试器生成的任务。"
},
{
"type": "cppbuild",
"label": "C/C++: g++.exe 生成活动文件",
"command": "E:/BaiduNetdiskDownload/x86_64-8.1.0-release-posix-sjlj-rt_v6-rev0/mingw64/bin/g++.exe",
"args": [
"-fdiagnostics-color=always",
"-g",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe",
//"-I", //包含头目录
//"C:\\Users\\Administrator.DC_LENG\\Desktop\\cpptest", //头目录路径
//"C:\\Users\\Administrator.DC_LENG\\Desktop\\cpptest\\datamanager.cpp", //不想一个个编译成 .o文件，直接包含 cpp 文件
"-I",
"C:\\Program Files\\MySQL\\MySQL Server 8.0\\include", // mysql头文件，有顺序要求，要求放在被导入文件之后，
"-L",
"C:\\Program Files\\MySQL\\MySQL Server 8.0\\lib", // mysql 库文件 dll
"-llibmysql" // 导入那个库
],
"options": {
"cwd": "E:/BaiduNetdiskDownload/x86_64-8.1.0-release-posix-sjlj-rt_v6-rev0/mingw64/bin"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "调试器生成的任务。"
}
],
"version": "2.0.0"
}
3. 把libmysql.dll复制到主函数所在的文件夹
4. testcode
#include <iostream>
#include <mysql.h>
using namespace std;
int main (){
cout << "Hello, world!" << endl;
// q1();
MYSQL conn;
int res;
mysql_init(&conn);
if (mysql_real_connect(&conn, "127.0.0.1", "root", "pswd", "test", 0, NULL, CLIENT_FOUND_ROWS)) //"root":数据库管理员 ,:123密码 "test":数据库的名字
{
printf("connect success!\n");
res = mysql_query(&conn, "insert into test values('user','123456')");
if (res)
{
printf("error\n");
}
else
{
printf("OK\n");
}
mysql_close(&conn);
}
else
{
printf("connect error!\n");
cout << mysql_error(&conn) << endl;
}
return 0;
}
