Unresolved symbols in Query (Lockable)

[Pedro Lamarão]

Compiling my application I get:

sql.obj : error LNK2001: unresolved external symbol "private: virtual
void __thiscall mysqlpp::Query::unlock(void)"
(?unlock@Query@mysqlpp@@EAEXXZ)
sql.obj : error LNK2001: unresolved external symbol "private: virtual
bool __thiscall mysqlpp::Query::lock(void)" (?lock@Query@mysqlpp@@EAE_NXZ)

The following test case exhibits the problem.

#include <mysql++.h>

using namespace mysqlpp;

int
main (int argc, char* argv[]) {
    Connection connection(true);
    Query query(&connection, true);
    return 0;
}

It is so contrived I think I may be missing something. But what?
