楼主

软件：QT SDK v1.2.1 （Qt4.8.1），mysql：mysql-installer-community-5.5.28.3，安装网上指点安装，内含 .../include;.../lib等必要目录；操作系统win7 64位
参考：
Qt4 OpenSource for mingw中编译MySQL驱动 http://www.qtcn.org/bbs/read-htm-tid-4210.html，

其中：cd c:\mysql\lib

reimp -d libmysql.lib
dlltool -k -d libmysql.def -l libmysql.a

这一步没有问题，可以生成。
然后在dos模式下，进入c: /Qt/QtSDK/QtSources/4.8.1/src/plugins/sqldrivers/mysql
运行：qmake -o Makefile "INCLUDEPATH+=C:\mysql55\clude" "LIBS+=C:\mysql55\lib\libmysql.a" mysql.pro
正常生成Makefile文件；
运行：mingw32-make 后，

出现如下错误：

构建项目mysql 时发生错误 (目标: 桌面)

当执行构建步骤 'Make'时

以上提示没有定义的参数，经查找，都是在 mysql/include 下的mysq.h 里定义的参数。

请问各位大神：本人的这个错误，是否mysql.h 在编译过程中没被编译进去呢？如果是，该如何解决啊？

如果不是mysql.h 的问题，可能的问题会是什么啊？谢谢各位了。

大神，我只是操作系统是64位的哦，SDK应该32位的吧。

第一贴最最后面那个关于myshql.h的问题麻烦给点建议哦，走投无路了啊。。

问题初步解决：
考虑了很久，决定把下载的mysql从5.5 降到大家都编译成功的5.1.
参照各位大神的文章，生成libmysql.a 后，从qtcreator中打开mysql.pro,，并将其内容改成如下内容后：

TARGET = qsqlmysql
INCLUDEPATH+=C:/MySQL/include
LIBS += -LC:/MySQL/lib/opt/ -llibmysql
SOURCES = main.cpp
include(../../../sql/drivers/mysql/qsql_mysql.pri)
include(../qsqldriverbase.pri)

分别编译 debug和release版本，成功！！！！！！！！！！！！！！！！！！
看来是mysql版本的问题，之前为这个搞了快8.9天了。。我的4个文件啊。。。

mysql 从5.5换成5.1 成功了?遇到和你同样的问题,难道要真的换MySQL 的版本啊
