我下载并安装了 mysql-noinstall-5.1.11-beta-win32
从安装目录得到了include目录和lib目录下的文件
我的开发环境是Dev-C++ 4.9.9.2

到底怎么办呀！
请大家帮帮我！

coldwarm

这个库应当是给vc提供的吧?你下载时要没有告诉你这个库是for mingw的?

你用devcpp的包管理器下载它提供的预编译的libmysql在试一下。

fuer

devcpp的包管理器我没搜到
干脆我又在vc中编译了一下
源码：
// ckient1.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#define def_host_name   NULL
#define def_user_name   NULL
#define def_password    NULL
#define def_db_name     NULL

MYSQL *conn;


int main(int argc, char* argv[])

我已经下载并安装了 mysql-noinstall-5.1.11-beta-win32
从安装目录得到了include目录和lib目录下的文件并复制到了vc++的INCLUDE目录和LIB目录
并在project->settings和tool->options中设置了
就是过不去呀？

#include "stdafx.h"

这个头文件里面包含了mysql的头文件吗?

fuer

一语点中
我把头文件都包含到了"stdafx.cpp"中
修改程序把该包含的头文件都包含到"stdafx.h"中编译通过！
看来我用的mysql库文件是为vc提供的
谢谢coldwarm大侠
顺便问一下我怎样才能在devcpp中编译成功呢？
你说的“devcpp的包管理器”要怎么搞到以及怎么使用呢？

coldwarm

devcpp安装时应当自己带着。

大概在devcpp的tools菜单位置吧，有一个被称为包管理器的菜单项，选中该菜单后，会出现一个让你选择要连接的站点的组合框，一般选中第二个站点，里面有libmysql。选中并下载，就会下载一个devpark包。

谢谢楼上的我装上了devpak包并且我的程序编译成功了，感觉很好用
