QSqlDatabase Link error

[scotty2012]

Hi. I'm new to Qt, but have decent experience in C++. I am trying to use QSqlDatabase to connection to MSSQL over an ODBC connection. I've verified I'm linking with QtSqld4.lib and have included QtSql in my app.

The problem I am having is this:

Error	3	error LNK2001: unresolved external symbol "public: static char * QSqlDatabase::defaultConnection" (?defaultConnection@QSqlDatabase@@2PADA)	check_db.obj	restorer
Error	4	error LNK2001: unresolved external symbol "private: static struct QString::Data QString::shared_null" (?shared_null@QString@@0UData@1@A)	check_db.obj	restorer
