Hello,

I'm porting some code fromVS10 to the VS12 compiler on windows. I have a problem compiling code like the following:

//Test.cpp

#include <boost/multi_index_container.hpp>

#include <boost/multi_index/random_access_index.hpp>

#include <boost/multi_index/hashed_index.hpp>

#include <boost/multi_index/identity.hpp>

template<typename T>

class test

{

public:

typedef typename boost::multi_index_container <

T*,

boost::multi_index::indexed_by <

boost::multi_index::random_access<>,

boost::multi_index::hashed_non_unique < boost::multi_index::identity<T*> >

>

> container_t;

typedef typename container_t::nth_index<0>::type sequence_index_t;

};

This does not compile and gives the following error message:

1> Test.cpp

1>D:\test\Test.cpp(18): error C2059: syntax error : '<'

1> D:\test\Test.cpp(19) : see reference to class template instantiation 'test<T>' being compiled

1>D:\test\Test.cpp(18): error C2238: unexpected token(s) preceding ';'

I'm unable to find the reason for this error. Is it a compiler error, or is something wrong with my declaration?

Regards,

Johannes

You're missing the template keyword in front of nth_index: typedef typename container_t::template nth_index<0>::type sequence_index_t; VC is just being standard compliant here.
