Thanks, Martin.

I have search for deque instanciation... there is no deque in source =
file and include for homoSyntagmaticConstraints.cpp.

I tried dumpbin as you suggest.

I find in graph library the source file that use deque objet.

I have used dumpbin on this obj file and I find this... which is suspect =
for me (there is seceral deque export !), two examples :

   /EXPORT:??_F?$deque@IV?$allocator@I@std@@@std@@QAEXXZ
   =
/EXPORT:??0?$deque@IV?$allocator@I@std@@@std@@QAE@ABV?$allocator@I@1@@Z

This file should not export this object, isn't it ?

In homoSyntagmaticConstraints.obj there is no /EXPORT symbols...

Could you say me please if I'm wrong. I need to export class A from =
graph lib in order to be use in other dll.

So, in graph lib I have a Class A which inherits of deque that I have =
declare as

Class DLLExportGraph : public B, public std::deque<C>

where DLLExportGraph is defined as=20
#ifdef GRAPH_EXPORTS

#define DLLExportGraph _declspec (dllexport)

#else

#define DLLExportGraph _declspec (dllimport)

#endif

I know this is the correct syntax for non template class, perhaps there =
is something different for template classes ?

    Thanks for your help,

            Nadine

PS : output file are so big (either compressed !) if you really need =
them I will send you
