[odb-users] Problem: Generated unfinished -odb.cxx with
unimplemented pure virtual function

Compiler version: obd 2.5.0-b.25+1
Building environment: build2 on ubuntu 22.04.4LTS
GCC version: gcc 11.04
Issue: the odb compiler doesn't finish generating the -odb.cxx file
it stops after generating the init functions.
To reproduce the problem, compile the Persion.h with the following command
line:
odb --database sqlite --generate-query --generate-schema --std c++11
Persion.h
The Person.h file:
//=============================================
class Person {
public:
virtual void test() = 0;
};
#pragma db object
class Student : public Person {
public:
int id;
};
//=============================================
The tail of generated Persion-odb.cxx:
//=============================================
......
void access::object_traits_impl< ::Student, id_sqlite >::
init (object_type& o,
const image_type& i,
database* db)
{
ODB_POTENTIALLY_UNUSED (o);
ODB_POTENTIALLY_UNUSED (i);
ODB_POTENTIALLY_UNUSED (db);
// id
//
{
int& v =
o.id;
sqlite::value_traits<
int,
sqlite::id_integer >::set_value (
v,
i.id_value,
i.id_null);
}
}
}
#include <odb/post.hxx>
//==============================================
