Error connecting to Oracle database

[NAYZAKAY44]

HI everybody,
I use Microsoft windows Vista 32 bit, I installed Qt SDK 2010.04 4.7.0 (32 bit) Open source, I installed oracle 10g express.

I did an application that needs a database connection. So I had to compile the OCI driver to connect to the database.
So I did like this:
I open the Qt command Prompt.
And I typed:

set INCLUDE=%INCLUDE%;C:\oraclexe\app\oracle\product\10.2.0\server\OCI\includ
set LIB=%LIB%;C:\oraclexe\app\oracle\product\10.2.0\server\OCI\lib\MSVC
set PATH=%PATH%;C:\oraclexe\app\oracle\product\10.2.0\server\BIN

set QT_PLUGIN_PATH=C:/Qt/plugins/sqldrivers
cd C:\Qt\2010.04\qt\src\plugins\sqldrivers\oci                                   
qmake -o Makefile oci.pro                                                                                  
mingw32-make

To copy to clipboard, switch view to plain text mode 

I don't know if my compilation is correct or not...!!
But when I execute my program, it appears this message to me:

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

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

To copy to clipboard, switch view to plain text mode 

I don’t know why the OCI driver is not loaded!!
Help plzzz
Thanks

Hey,
After compiling the driver you get both release and debug versions,...that is if you compiled them both. Now you need to copy these four files files(including the .lib) file to the folder plugins/sqldrivers ...in the Qt directory. Then the QT framework will not complain anymore. Infact in that folder you have other compiled drivers as well.

Good luck
