Hi All,

I have a database class that accesses a local file using Qt's Sqlite3 drivers. The database class is implemented as a Singleton model and is accessible in that manner by the rest of the application, and thus guaranteeing that only one process is accessing the database at any given time.

My problem is that when I use a QSqlQueryModel and call its setQuery() method, I get a QSqlError of "database is locked." This error is thrown on my FIRST attempt to query the database, which happens to be a SELECT statement.

One more caveat is that this code works perfectly well under Linux (Ubuntu) and Mac OS X, but fails with the above error on an embedded ARM920t platform.

On the same target hardware, I have been able to successfully run a few simple "Hello World" style applications, so I know that at least the basic cross-compiled libraries are correct.

Cross compiled under Ubuntu, using the Qt 4.5.3 embedded source.

Thanks in advance.
