Re: [Boost-users] [accumulators] Compilation Problem

Hi,

When I use this

std::cout << "  count(acc)      = " << 
boost::accumulators::extract::count(angular_acc) << std::endl;

to extract a value from my accumulator, I get compile errors :

boost\detail\function1.hpp(67) : error C2065: 'UnaryFunction' : 
identificateur non déclaré ("undeclared identifier")
...
boost\detail\function1.hpp(67) : error C2275: 'impl' : utilisation non 
conforme de ce type comme expression ("*illegal use of this type as an 
expression")*
boost\detail\function1.hpp(67) : error C2059: erreur de syntaxe : ')' 
("syntax error")
boost\detail\function1.hpp(67) : error C3861: 'BOOST_CONCEPT_ASSERT': 
identificateur introuvable, même avec une recherche qui dépend de 
l'argument ("identifier not found")

I am using boost 1.34.1 under VC 2003. Any issue ?

Regards

Olivier
