I just don´t get the MySQL Driver Compiled

[alex04721]

Creating library file: c:\Qt\2010.02.1\qt\plugins\sqldrivers\libqsqlmysql 4.a
mingw32-make[1]: Leaving directory `C:/Qt/2010.02.1/qt/src/plugins/sqldrivers/my
sql'

what the fuck Oo


hm... he said he created it but there is no *.a file

the file is created but i wonder, its in sqldrivers\ but not in sqldrivers\mysql

ive tested it.

QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QODBC3 QODBC

edit : the qsqlmysql4.dll is created in C:\Qt\2010.02.1\qt\plugins\sqldrivers

ive tested it.

regarding the .a and .dll... I think the .a is an intermediate step and the archiver will create a dll from it. Yes, the destination is a bit different than the structure of the src folder - this is not that surprising to me.

the qsqlmysql4.dll is created in C:\Qt\2010.02.1\qt\plugins\sqldrivers

ok, we're getting closer.
Now when you start the Qt prompt, make sure you have the correct path in there, otherwise Qt won't be able to locate the plugins.
Also, make sure you are running the release version of your app, OR make sure you also build the debug version of the qslqmysql dll, which is called qsqlmysqld4.dll.

And make sure the mysql client lib is in your path.

i do not exactly know whaht you mean. I am usually working with the QT Creator. I compiled my mysql app with the QT Creator in Release Mode so CONFIG+=release is set. But the plugin still isn´t found.

just for a test, create a folder and put the following in it:
QtGui4.dll
QtCore4.dll
QtSql4.dll
libgcc_s_dw2-1.dll
mingwm10.dll
<yourapp>.exe
libmysql.dll
plugins <--- create this folder and copy qslqmysql.dll into it

Then start a Qt command prompt and try running your program.

btw: you do have the following line in your .pro file right?
QT += sql
