I guess this driver has not been tested on a 64-bit platform (at least not
with with such a recent GCC compiler). Please send a bug report via the
feedback form on the Trolltech web site:
http://trolltech.com/developer/bugreport-form
The fix would be to change:
QIBaseDriver::QIBaseDriver(void *connection, ...
to something like:
QIBaseDriver::QIBaseDriver(unsigned int connection, ...
Indeed the definition of 'isc_db_handle' which really is a 'FB_API_HANDLE'
looks like:
#if defined(_LP64) || defined(__LP64__) || defined(__arch64__) || defined(_WIN64)
typedef unsigned int FB_API_HANDLE;
#else
typedef void* FB_API_HANDLE;
#endif
