i'd like to build a heterogenous container based on the boost::variant datastructure. My code looks like this: // forward-Deklarationen:
class fExport FB_Ordered;
class fExport FB_Dictionary;
C:\dev\boost_1_52_0\boost/checked_delete.hpp(32) : error C2027: use of undefined Type "FB_Ordered"
what i want to do is to create a container fb_dictionary which can hold datatypes that are listed in the valuedicttype and which can accept keyvalues of int and string (see above). fb_ordered is another container defined in a diferent header file so i need the forward declarations. Could anybody please give me a hint in the right direction? I am using vs2008.

A full, expected-to-compile example is always helpful. But the errors I'm
getting with the above typedefs seem more related to the lack of this
fExport keyword you're using. If I remove the fExport stuff then all the
typedefs compile fine, and I don't get the undefined type error until I try
to instantiate basedict (obviously; FB_Ordered and FB_Dictionary need to be
defined by then).

FP_Ordered has to be complete at the point where
the destructor of variant is instantiated. The
same thing goes for FB_Dictionary.
thanks for your help. The fexport keyword was to decide if i build a dll or another application that is using my class. I removed it since my module will compile to a static library and until now all works fine.
greetings,
Georg
