Boost C++ Libraries: Ticket #6525: format atldbgmem.h m_storage VS2010

anonymous — Tue, 26 Mar 2013 14:38:26 GMT

This is still the case with boost 1.53.0 and VS2012. If I include e.g. boost property tree, and compile in debug mode, I get a

1>c:\boost\boost_1_53_0\boost\optional\optional.hpp(346): error C2061: syntax error : identifier 'm_storage'

I use the following for memory debugging:

#ifdef WIN32
	#include <crtdbg.h>
#endif
#ifdef _DEBUG
	#ifndef DBG_NEW
		#define DBG_NEW new ( _NORMAL_BLOCK , __FILE__ , __LINE__ )
		#define new DBG_NEW
	#endif
#endif  // _DEBUG

Without that, or in release mode, it's working fine.

Can we somehow fix this?

I have what appears to be a workaround; at least it helped when I hit this problem.

Check whether the #ifdef _DEBUG/#endif that redefines new is before or after the #include <boost/format.hpp>. I hit this problem when new is redefined before including format.hpp, but do not have this problem if new is redefined afterwards. (I'm using a slightly different way to redefine new, but that's most likely not material.)

In other words, this caused the compile error that you are reporting:

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
#include <boost/format.hpp>

and this worked for me:

#include <boost/format.hpp>
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

owner changed from Samuel Krempp to Fernando Cacciola
component format → optional

This is an issue in Boost.Optional; reassigning.
