在Ubuntu下费了好长时间终于让C操作MySQL成功了,在此把方法记下来,留着以后用。先安装MySQL
代码:
sudo apt-get install mysql-server mysql-client

再装开发包
代码:
sudo apt-get install libmysqlclient15-dev

可以用以下代码测试一下
代码:
/* Simple C program that connects to MySQL Database server*/
#include
#include

main() {
    MYSQL *conn;
    MYSQL_RES *res;
    MYSQL_ROW row;

   char *server = "localhost";
   char *user = "root";
   char *password = ""; /* 此处改成你的密码 */
   char *database = "mysql";

    conn = mysql_init(NULL);

   /* Connect to database */
   if (!mysql_real_connect(conn, server,
          user, password, database, 0, NULL, 0)) {
      fprintf(stderr, "%s\n", mysql_error(conn));
      exit(1);
   }

   /* send SQL query */
   if (mysql_query(conn, "show tables")) {
      fprintf(stderr, "%s\n", mysql_error(conn));
      exit(1);
   }

    res = mysql_use_result(conn);

   /* output table name */
   printf("MySQL Tables in mysql database:\n");
   while ((row = mysql_fetch_row(res)) != NULL)
      printf("%s \n", row[0]);

   /* close connection */
    mysql_free_result(res);
    mysql_close(conn);
}


编译:


方法一:gcc test.c -o test -I/user/include/mysql                               试了一下,提示找不到mysql.h。

我试了一下,提示找不到mysql.h。
分析:
/user/include/mysql:全是.h文件,应该应编译阶段
/user/lib/mysql:是静态库和动态库,,应该与上面的.h文件对应,用于连接阶段。

方法二:gcc test.c -o test -L/user/lib/mysql -lmysqlclient                成功!

方法三:gcc test.c -o test $(mysql_config --cflags) $(mysql_config --libs)

或者:gcc test.c -o test $(mysql_config --cflags --libs)                        成功!
