QOci with qt 4.7.3 x64

[Harald Klingel]

Hi,
I've successfully built qt4.7.3 in 64 bit. I've built with option -qt-sql-oci beacuse I want to connect to an oracle db.

Now when I call
QSqlDatabase::addDatabase( dbType, connectionName );

I get
Warning: QOCIDriver: unable to create environment

Can somebody give me a hint?

Any help appriciated,
Kind regards,
Harald

I've checked for
QSqlDatabase::contains("QOCI") and the result is false.

Could it be that oci.dll is not found? Or might there be a problem because the oci.dll was build for x64 systems?
