我编译出来的是debug版本。真奇怪，谁能告诉我？

按照上面的步骤，我不能执行dlltool.exe 文件是怎么会事？该怎么解决，请高人指点？
另外想问下安装qt creator 后在 mingw 编译器下要怎么编译mysql驱动才能成功？

今天安装成功总结下：
1、  出现错误：
mingw32-make -f Makefile.Release
  Makefile.Release:104: *** multiple target patterns.  Stop.
  mingw32-make[1]: Entering directory `D:/Qt/4.3.2/src/plugins/sqldrivers/mysql'
  mingw32-make[1]: Leaving directory `D:/Qt/4.3.2/src/plugins/sqldrivers/mysql'
  mingw32-make: *** [release] Error 2
解决：
set lib=
set include=
---------
即设置lib和include为空。否则会在makefile里加上很多qt库需要的无用的头文件，如果你原来lib和include不为空。
参考：http://www.qtcentre.org/forum/f-installation-5/t-did-you-try-qt-43-opensource-on-winxp--7428.html
2、安装lz的方法，qt-4.3.0下编译出来了驱动，但是下了苦功夫也没弄通，一直提示driver not load
因碰到了上面的问题，换成qt-4.3.2.后，顺利就可以连接mysql了。
给大家提供下载地址
Qt 4.3.2   :
http://www.qtcn.org/download/qt-win-opensource-4.3.2-mingw.exe
mySql Server version: 5.1.40:
http://mysql.isu.edu.tw/Downloads/MySQL-5.1/mysql-noinstall-5.1.40-win32.zip

3、其他出现的错误  都可以在网上轻易的找到。

希望对楼下的有帮助。

我用的是mingw,运行reimp和dlltool,生成的libmysql.a始终是空文件,在网上搜了很多同样遇到这种问题的,但都没能解决问题,到底是什么问题啊?

如果直接使用libmysql.lib,添加到LIBS里面,倒是能链接成功,但是运行就会出错,对话框提示"You can't do that without a process to debug",而且调试无法停止,只能退出qt creator

这个描述过程是正确的(for win, Qt 4.6.2, MinGW, MySQL 5.1.44):

qt 版本 4.7 32bit mysql 版本 5.1.52

成功做出了 libmysql.a 這個文件然後運行

d:\qt\src\plugins\sqldrivers\mysql>qmake -o makefile INCLUDEPATH+="D:\mysql32\include" LIBS+="D:\mysql32\lib\opt\libmysql.dll" mysql.pro

然後就出現了

不能make 失敗了鬱悶很多天了版主大大幫幫忙吧或者哪位幫我編譯一個不勝感激我的qq 53137326 Email. tensmyo@hotmail.com

大哥，我的生成libmysql.a 文件后，按照以后的步骤去做一直编译出错。

我按照步骤编译，出现了以prl为后缀名的插件。搞不懂改选择mysql.pro应该是什么类型的项目比较好呢？是C++LIBRARY/SHARED LIBARY/。。。请指点下。后来出现了mysql.dll，和别人编译出的名字怎么不一样啊，也不知道能不弄用，我用的QT 4.7，

你好，我从别人那里拿到编译好的库，可是构建使用MySQSL 程序的debug版本总是不成功，构建release版本却可以。怎样才能编译debug版本？

出现这种错误是怎么回事啊？vs2008编译器装了多个会产生这种情况吗

不行啊...

有这个错误。但是用正斜杠的话。到最后编译貌似没错。但是在文件下没有dll文件只有qsqlmysqld.prl 和libqsqlmysqld.a这个文件啊。求指教。

QtSDK1.2.1 + MySQL5.5，特么的mysql的驱动都编译了，也拷贝过去了，运行程序的时候，报打开数据库失败，看了一下错误，报的是Driver not loaded Driver not loaded

db = new QSqlDatabase();
    db->addDatabase("QMYSQL");
    db->setHostName("localhost");
    db->setDatabaseName("MySQL");
    db->setUserName("root");
    db->setPassword("1111");

    QSqlError err;
    if (!db->open())
    {
        qDebug()<<"Unable to open Database";
        err = db->lastError();
        qDebug()<<err.text();
    }
    else
        qDebug()<<"Open Database sucess!";

大大，我还是不行哦，帮我看看。
win7 64 qt5.1 mysql5.6

我已经生成 libmysql.a 文件

在C:\qt-everywhere-opensource-src-5.0.2\qtbase\src\plugins\sqldrivers\mysql目录下
手动修改mysql.pro 添加

INCLUDEPATH += "C:\mysql\include"
LIBS+= "C:\mysql\lib\libmysql.a"

然后用MinGW 4.8 32 bit
qmake -o kefile mysql.pro

然后
mingw32-make

以下是最后提示：

c:/qt/qt5.1.1/tools/mingw48_32/bin/../lib/gcc/i686-w64-mingw32/4.8.0/../../../..
/i686-w64-mingw32/bin/ld.exe: cannot find -llibmysql
collect2.exe: error: ld returned 1 exit status
Makefile.Release:80: recipe for target '..\..\..\..\plugins\sqldrivers\qsqlmysql
.dll' failed
mingw32-make[1]: *** [..\..\..\..\plugins\sqldrivers\qsqlmysql.dll] Error 1
mingw32-make[1]: Leaving directory 'C:/qt-everywhere-opensource-src-5.0.2/qtbase
/src/plugins/sqldrivers/mysql'
makefile:38: recipe for target 'release-all' failed
mingw32-make: *** [release-all] Error 2

有人懂吗？我的qq：171741688 帮帮我吧

回 XChinux 的帖子

XChinux:这么说你编译成功了。
在.pro里加上QT += sql (2006-04-24 09:16)

如何编译ORCAL呢，在oci.pro里面加入
INCLUDEPATH += D:\\app\\admin\\product\\11.2.0\\dbhome_1\\OCI\\include
LIBS += D:\\app\admin\\product\\11.2.0\\dbhome_1\\OCI\\lib\MSVC\\oci.lib
LIBS += -L D:/app/admin/product/11.2.0/dbhome_1/BIN -loci

可以这个dll是msvc编译的，用QT编译的时候，总是提示
qt file format not recognized
