问题描述
我正在尝试使用 C++ 开发一个使用 MySQL 的应用程序.我从他们的网站下载了该库，并尝试编译以下代码:
I am trying to develop an application that uses MySQL using C++. I downloaded the library from their website and I have attempted to compile the following code:
#include <iostream>
#include <windows.h>
#include <mysql.h>
using namespace std;
int main()
{
MYSQL *connection, mysql;
MYSQL_RES *result;
MYSQL_ROW row;
mysql_init(&mysql);
}
具有 mysql_init(&mysql); 的那行给了我一个编译错误
The line that has mysql_init(&mysql); gives me a compilation error
undefined reference to `mysql_init@4'
我猜这是由于库错误.我按顺序链接 mysqlclient.lib 和 libmysql.lib .我需要做什么才能在不需要 dll 文件的情况下进行编译?那可能吗?谢谢你.注意:我在 Windows 7 x64 上使用 mingw32 为 Windows 开发应用程序.
I am guessing this is due to a library error. I am linking mysqlclient.lib and libmysql.lib in that order. What do I need to do to make this compile without requiring a dll file? Is that possible? Thank you.
Note: I am using mingw32 on Windows 7 x64 to develop an application for Windows.
推荐答案
也许这个链接会有所帮助.它指出 mysqlclient.lib 是静态库，而 libmysql.lib 是动态库，所以我认为您不应该同时链接两者.
Maybe this link will help. It states that mysqlclient.lib is the static library and libmysql.lib is the dynamic library, so I don't think you should be linking both.
