Build log different to build messages

(1/2) > >>

smallB:
If I set in compiler options compiler logging to full command line and try to compile this (erroneous program):

--- Code: ---#include <iostream>
#include <typeinfo>
#include "Demangle.h"
using namespace std;
template<class... Types>
struct X
{

};

template<class A,class B,class... Types>
struct X<A,B,Types...>
{
    typedef A type;
    typedef X<B,Types...> next;
    A head;

};

//template<class A,class... Types>
//struct X<A,Types...>
//{
//    typedef A type;
//    typedef X<Types...> next;
//    A head;
//
//};

template<class B>
struct X<B>
{
    B head;
    typedef B type;
    typedef B next;
};

template<int index, class Sequence>
struct get
{
        typedef typename get<index - 1,typename Sequence::next>::type type;
};

template<class Sequence>
struct get<0,Sequence>
{
    typedef typename Sequence::type type;
};


int main()
{
    typedef X<int,double,char> x;
    //cout << demangle(x.get_head());
     cout << demangle(typename get<3,x>::type());
    return 0;
}

, from build messages (inside cb):

things look even worse when I try to open this file internally via cb(in cb's html viewer).

zabzonk:
And your problem is ... what?

smallB:
Hi Neil, my problem is that in build log specializations of 'get' meta function are not listed with their correct types. I think that log should be as detailed as possible, and this isn't.

The build log shows everything the compiler tells you. If that is not enough, complain to the GCC guys.

smallB:
Hi Morten,
But in cb I'm getting correct types displayed: get<1,X<int,double>>, this isn't the case in log file: get<1,X>. So who is responsible for that cb or gcc?
