1. 安裝mysql的時(shí)候一定要安裝"Libs & Include Files"的開(kāi)發(fā)者模塊

2. 設(shè)置環(huán)境變量

PATH
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Microsoft SQL Server\90\Tools\binn\;C:\Qt\4.5.0\bin;C:\Program Files\Microsoft Visual Studio 8\VC\bin;C:\Program Files\Microsoft Visual Studio 8\Common7\IDE

分別是以下幾個(gè)目錄:

%SystemRoot%\system32;
%SystemRoot%;
%SystemRoot%\System32\Wbem;
C:\Program Files\Microsoft SQL Server\90\Tools\binn\;
C:\Qt\4.5.0\bin;
C:\Program Files\Microsoft Visual Studio 8\VC\bin;
C:\Program Files\Microsoft Visual Studio 8\Common7\IDE

INCLUDE
C:\Program Files\Microsoft Visual Studio 8\VC\include;C:\Program Files\Microsoft Visual Studio 8\VC\ATLMFC\INCLUDE;C:\Program Files\Microsoft Visual Studio 8\VC\INCLUDE;C:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\include;C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\include;C:\Qt\4.5.0\include\QtCore;C:\Program Files\MySQL\MySQL Server 5.1\include

分別是以下幾個(gè)目錄

C:\Program Files\Microsoft Visual Studio 8\VC\include;
C:\Program Files\Microsoft Visual Studio 8\VC\ATLMFC\INCLUDE;
C:\Program Files\Microsoft Visual Studio 8\VC\INCLUDE;
C:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\include;
C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\include;
C:\Qt\4.5.0\include;
C:\Program Files\MySQL\MySQL Server 5.1\include

LIBPATH
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727;C:\Program Files\Microsoft Visual Studio 8\VC\ATLMFC\LIB
分別是以下幾個(gè)目錄

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727;
C:\Program Files\Microsoft Visual Studio 8\VC\ATLMFC\LIB

LIB
C:\Program Files\Microsoft Visual Studio 8\VC\ATLMFC\LIB;C:\Program Files\Microsoft Visual Studio 8\VC\LIB;C:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\lib;C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\lib;C:\Program Files\MySQL\MySQL Server 5.1\lib\debug;C:\Program Files\MySQL\MySQL Server 5.1\lib\opt

分別是以下幾個(gè)目錄：

C:\Program Files\Microsoft Visual Studio 8\VC\ATLMFC\LIB;
C:\Program Files\Microsoft Visual Studio 8\VC\LIB;
C:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\lib;
C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\lib;
C:\Program Files\MySQL\MySQL Server 5.1\lib\debug;
C:\Program Files\MySQL\MySQL Server 5.1\lib\opt

3. 為防止中文亂碼，修改mysql驅(qū)動(dòng)的源代碼
修改codec函數(shù)，修改后為：

Cpp代碼

1. static QTextCodec* codec(MYSQL* mysql)   
2. {   
3.   return QTextCodec::codecForName("GBK");   
4. #if MYSQL_VERSION_ID >= 32321   
5.   QTextCodec* heuristicCodec = QTextCodec::codecForName(mysql_character_set_name(mysql));   
6.   if (heuristicCodec)   
7.     return heuristicCodec;   
8. #endif   
9.   return QTextCodec::codecForLocale();   
10. }  

static QTextCodec* codec(MYSQL* mysql){return QTextCodec::codecForName("GBK");#if MYSQL_VERSION_ID >= 32321QTextCodec* heuristicCodec = QTextCodec::codecForName(mysql_character_set_name(mysql));if (heuristicCodec)return heuristicCodec;#endifreturn QTextCodec::codecForLocale();}

4. 執(zhí)行

cd C:\Qt\4.5.0\src\plugins\sqldrivers\mysql
qmake -o Makefile mysql.pro
nmake

如果成功就會(huì)在C:\Qt\4.5.0\plugins\sqldrivers目錄下產(chǎn)生一系列文件：

qsqlmysql4.dll
qsqlmysql4.exp
qsqlmysql4.lib
qsqlmysqld4.dll
qsqlmysqld4.exp
qsqlmysqld4.ilk
qsqlmysqld4.lib
qsqlmysqld4.pdb
