After all, perhaps i'm having a different issue:


dir1/A.hpp
===================
namespace NS
{

struct A {
...
...const T* underlying;
...
};
struct selector {
  int id;
  int type;
};
void set_A_underlying(A&, const selector&);

}


dir1_odb/A.hpp
====================
#include <odb/core.hxx>
namespace NS
{
#pragma db value(selector) definition

#pragma db object(A) table("A") definition
#pragma db member(A::underlying) transient
#pragma db member(A::ulid) virtual(selector) \
  get( selector(this.underlying->type(), this.underlying->id)) \
  set(set_A_underlying (this,(?)))
}


Calling odb on dir1_odb/A.hpp with the proper options generates
successfully the A.hxx A.ixx A.cxx

but compiling with that generates this error:

error: ‘image_type’ in ‘class
odb::access::composite_value_traits<NS::selector, (odb::database_id)1u>’
does not name a type

It looks like no traits get generated for selector.

Rds,
