[odb-users] Unknown action or bug in odb compiler

[Александр Матушкин]

Hello.

 

Found problem with compiler ODB.

Enviroment:

OS: Raspian. 

GCC G++ 4.9.2.

 

Present file(smarthome_types.h) with descriptions database object classes.
(Generated by thrift compiler).

No edit manually. Make be regenerate.

All needed classes are present in separated namespace: smarthouse.

Create new header file odb-thrift.hxx. 

For "non-intrusive conversion" create this text:

 

#ifndef ODB_THRIFT_HXX_

#define ODB_THRIFT_HXX_

 

#include "smarthome_types.h"

 

namespace smarthouse {

  #pragma db object(Node)

  #pragma db member(Node::id) id

}

#endif

 

In <smarthome_types.h> present class Node. In class Node present filed id as
'int';

 

Compile this flie odb:

odb -d  mysql --generate-query --generate-schema odb-thrift.hpp

Success. No error. Present new files:

odb-thrift-odb.cxx,  odb-thrift-odb.hxx, odb-thrift-odb.ixx, odb-thrift.sql

But odb-thrift.sql is empty:

/* This file was generated by ODB, object-relational mapping (ORM)

* compiler for C++.

*/

In odb-thrift-odb.hxx:

// This file was generated by ODB, object-relational mapping (ORM)

// compiler for C++.

//

 

#ifndef ODB_THRIFT_ODB_HXX

#define ODB_THRIFT_ODB_HXX

 

#include <odb/version.hxx>

 

#if (ODB_VERSION != 20400UL)

#error ODB runtime version mismatch

#endif

 

#include <odb/pre.hxx>

 

#include "odb-thrift.hpp"

 

#include "smarthome_types-odb.hxx"

 

#include <memory>

#include <cstddef>

 

#include <odb/core.hxx>

#include <odb/traits.hxx>

#include <odb/callback.hxx>

#include <odb/wrapper-traits.hxx>

#include <odb/pointer-traits.hxx>

#include <odb/container-traits.hxx>

#include <odb/no-op-cache-traits.hxx>

#include <odb/result.hxx>

 

#include <odb/details/unused.hxx>

#include <odb/details/shared-ptr.hxx>

 

namespace odb

{

}

 

#include <odb/details/buffer.hxx>

 

#include <odb/mysql/version.hxx>

#include <odb/mysql/forward.hxx>

#include <odb/mysql/binding.hxx>

#include <odb/mysql/mysql-types.hxx>

#include <odb/mysql/query.hxx>

 

namespace odb

{

}

 

#include "odb-thrift-odb.ixx"

 

#include <odb/post.hxx>

 

#endif // ODB_THRIFT_ODB_HXX

In .cxx file present the same.

Empty namespace odb.

If manually insert into smarthome_types.h after class Node definition but
into namespace smarthouse this lines:

#pragma db object(Node)

#pragma db member(Node::id) id

Odb generate valid classes, headers and sql files.Not emty.

Attempt modify odb-thrift.hxx to next form:

#ifndef OBD_THRIFT_HXX_

#define OBD_THRIFT_HXX_

 

#include "smarthome_types.h"

 

#pragma db namespace(smarthouse) object(Node)

#pragma db namespace(smarthouse) member(Node::id) id

 

#endif /* OBD_THRIFT_HXX_ */

Odb produce next error:

odb-thrift.hpp:13:34: error: name 'smarthouse' in db pragma object does not
refer to a class

odb-thrift.hpp:14:34: error: unknown db pragma member.

Attempt write odb-thrift.hxx to next form:

#ifndef OBD_THRIFT_HXX_

#define OBD_THRIFT_HXX_

 

#include "smarthome_types.h"

 

#pragma db object(smarthouse::Node)

#pragma db member(smarthouse::Node::id) id

 

#endif /* OBD_THRIFT_HXX_ */

Success. No error. But present empty files.

 

In what my error? How to receive result without changing the file
smarthome_types.h?

 

Thanks in advance.

Alexandr.
