linux mysql 找不到 <mysql/mysql.h>

原因：缺少libmysqlclient-dev，

安装：apt-get install libmysqlclient-dev

main.cpp

#include <iostream>

#include <mysql/mysql.h>

#include <stdlib.h>

using namespace std;

int main()

{

 

   MYSQL mysql;

    MYSQL_RES *result;

    MYSQL_ROW row;

    mysql_init(&mysql);

    mysql_real_connect(&mysql, "127.0.0.1", "root", "123456",

                       "mydb", 0, NULL, 0);

    mysql_query(&mysql, "select * from friends");

    result = mysql_store_result(&mysql);

    while ((row = mysql_fetch_row(result)))

    {

        cout << row[0] << " | " << row[1] << " | " << row[2] << " | "

             << row[3] << " | " << row[4] << " | " << row[5] << " | "

             << endl;

    }

    mysql_free_result(result);

    mysql_close(&mysql);

   

    return 0;
