[Boost-users] Issues trying to use boost::unordered_map

28 Sep 2016

      Hi,

I am trying to use a boost::unordered_map as a member of my class. The
unordered_map is defined as,

boost::unordered_map<int, int> a;

as a private member in the class. I have included

#include "boost/unordered_map.hpp"

using namespace boost;

This is the compilation error I get,

x_objs.cpp
c:\codeworks\common\lib\boost\boost\unordered\detail\buckets.hpp(767) :
error C2059: syntax error : '('

c:\codeworks\common\lib\boost\boost\unordered\detail\buckets.hpp(766) :

        with

            P=std::equal_to<int>
        ]

Can someone please help me?
