    Finally I've solved this. There were two things wrong. (1) I've configured the qt build with -qt-sql-oci and -plugin-sql-oci. There can only be one of them, the second one overrides the first. That's why QOCIDriver has not been included in QSql4 (2) The wrong oci.dll has been loaded. There was a copy of oci.dll (win32) in my debug folder. Don't known how it got there, but in any case this one was found before checking the path I've set in the debugging environment. I found that in the output of VS2010, where a list of all drivers loaded is shown. Some general tips for comiling qt with oci: check if the oci.lib and oci.dll have been build in the same mode (x64 or win32). You can do that in a VisualStudio command prompt with DUMPBIN /headers xxx.xxx configure the include path by using -I D:\Oci64\includes (or where ever you store these files configure the library path by using -L D:\Oci64\lib That's it.

    [quote author="Tobias Hunger" date="1311690814"]Static libraries in windows are really tricky when it comes to figuring out the tool chain. It should actually leave the MSVC flavor undefined in that case, but that seems to not happen for you. A work-around is to put a dynamic QtCore right next to the static one. Creator will pick that up first and figure out the correct ABI using it. Having said that: Could you please send me your static QtCore library? I would really like to see what is going wrong there when it tries to detect it. I'll send you a message via devnet with my email if you do not mind.[/quote] Hmm I think I know what's the problem: I am recompiling the msvc2008 package for msvc2010 instead of using the clean sources because it worked the first time for the non-static version. I had no idea that static libraries were this picky :P. If nothing else works, I'll try with the clean sources. Also, what do you mean with "putting a dynamic QtCore next to the static one"? Putting the dynamic dll in the bin folder of the static version? Or put it in the same folder as the lib? EDIT: replacing QtCore.dll with the non-static one fixed it! Thanks for the workaround. I mailed you the lib btw

    Both the machines have the same decoding libraries (Klite codec pack installed). I've already placed my backend dll inside phonon_backend (phonon_ds94.dll)... I look into my code and this is the Phonon::createPath methods that make my app crash. (Without, it launches, but no video and sound which is normal). It seems that vista has something different than 7 or XP. I wonder what ? OpenGL dll are already installed...I have no idea left!

    Are you aware the online installer installs sqlite for you? Why do you want to install it again using your package manager? Please use Qt instead of QT(=QuickTime)

    This is a "list of all Symbian OS codes":http://www.developer.nokia.com/Community/Wiki/Symbian_OS_Error_Codes. According to this document the description of Error -14 is: bq. KErrInUse -14 The specified object is currently in use by another program The Nokia Smart Intaller is compatible with "all Symbian 3.1 and later devices except Nokia 6650 AT&T variant and N96":http://doc.qt.nokia.com/smart-installer-1.1/smartinstaller-supported-devices.html. Your Nokia E61i is with "S60 3rd Edition initial release (Symbian OS v9.1)":http://www.developer.nokia.com/Devices/Device_specifications/E61i/. The conclusion is that Nokia E61i is not officially compatible with smart installer.

    I have a list of folders to add to the Include path for VS. I was assuming too much when I was compiling Qt. I ran into the same problem at work this morning with a new project, and had to copy the folders over from an existing project. I think I may have finally gotten it all up and running (assuming when I get home adding files to the Include path is all I need to do), and I can start my project. Thanks for all the help.
