Qt windows libmysql.dll

Question

I have installed MySQL 5.1.49 and the binary QT 4.6.2 for Visual Studio 2008. I configured Qt as follow:

C:\Qt>configure -static -no-webkit -plugin-sql-sqlite -plugin-sql-mysql -I C:\mysql\include -L C:\mysql\lib\optC:\Qt\src\plugins\sqldriver

Everything went fine, no errors. When I run nmake on my application everything runs fine, no errors as well. However when I execute my application under the debug folder I get a popup saying "Driver not loaded" (I have QT += sql under my project.pro)

If I goto C:\Qt\plugins\sqldrivers I dont see any libmysql, or any *mysql.dll only qsqlmysql.obj and qsqlmysqld.obj (there are files such as: qsqlite4.dll, qsqlpsql4.dll etc.)

I did try to build it manually by doing:

cd %QTDIR%\src\plugins\sqldrivers\mysql
C:\Qt\src\plugins\sqldrivers\mysql>qmake "INCLUDEPATH+=C:\mysql\include" "LIBS+=C:\mysql\lib\opt\libmysql.lib" mysql.pro
nmake

Everything compiles fine, no errors. However, I still don't find any libmysql.dll generated. Only file found is under C:\mysql\bin\libmySQL.dll

I have all the includes for MySQL under C:\mysql\include and the libraries under C:\mysql\lib\opt

Any ideas what could be the problem? Thanks

Have you tried using qt source instead of the binary one? I had a similar issue, however I was getting compile errors.
