    Question compiling Qt with custom SQLite support

    I have compiled my own SQLite, one that defautls foreign keys to be on be default. Now I would like to build that into Qt. Initally I used the following options to configure Qt on Win 7:

    configure -debug-and-release -opensource -plugin-sql-sqlite -plugin-sql-ibase -no-qt3support -platform win32-msvc -no-phonon -I C:\Apps\Firebird\Firebird_2_1\include -L C:\Apps\Firebird\Firebird_2_1\lib -l fbclient_ms

    I tried to changed it to: (add three options to the end)

    set SQLITE=<PATH>\SQLite
    configure -debug-and-release -opensource -plugin-sql-sqlite -plugin-sql-ibase -no-qt3support -platform win32-msvc -no-phonon -I C:\Apps\Firebird\Firebird_2_1\include -L C:\Apps\Firebird\Firebird_2_1\lib -l fbclient_ms -I %SQLITE% -L %SQLITE% -l sqlite3

    And I get the error: QWidget: Must construct a QApplication before a QPaintDevice after recompiling my project. What did I do wrong?

    Default Re: compiling Qt with custom SQLite support

    I did not copy the SQLite3.DLL into the Qt's bin folder, that is what I was doing wrong.
