[odb-users] Intermittent problems building solution

[Adam Walters]

Hi there,
I am experiencing an intermittent problem building an ODB-based solution in VS 2012. The application built and ran successfully previously but now produces build errors for the following code:

case.hxx


#include <string>
#include <memory>
#include <odb/core.hxx>

#pragma db object
class Case
{
public:
        const int getCaseId() const { return _caseId;}

private:
        Case() {}
        friend class odb::access;
        int _caseId;
};

#pragma db member(Case::_caseId) id auto

The code that actually produces the errors is where I try to query it and actually when  I typedef the query object:

        typedef odb::query<Case> query;


This produces the following errors in Visual Studio 2012:

error C2039: 'base_type' : is not a member of 'odb::query_selector<T,DB>'
error C2065: 'base_type' : undeclared identifier
error C2146: syntax error : missing ',' before identifier 'base_type'
error C2504: 'odb::query_selector_impl<T,DB,kind>' : base class undefined

The command line I am using to process the hxx file is

odb --std c++11 -I ../Include -d mysql --generate-query --generate-schema case.hxx
This happened previously and after some fiddling, mysteriously started working. I don't know what I did then and now it has come back again. Any suggestions as to what I am doing wrong here?

Cheers,
Adam
