Hi,
I'm starting to get to grips with boost and in particular on the SGI
platform. I was trying to use the boost::tuples and found that with
the SGI compiler v7.3.1.3m I was getting the following error
CC -LANG:std -I/images/src/boost/from_cvs/boost
-I/images/src/boost/from_cvs/boost/boost/compatibility/cpp_c_headers/
-o tupple tupple.cpp

I'm working with the code from CVS because it compiled better on the
SGI, I looked at the code, and basically I think it's getting confused
due to my test program including a "using namespace std;" so I
modified the tuple_io.hpp to specifically mention
detail::format_info::close rather than the bare close and then my
example works (I also made explicit the other cases of the switch
statement).
Is there a more recomended way of doing this? Almost everywhere else
in that file the full specification of the enum is given.
My code is something like:
#include <vector>
#include <iostream>
#include <algorithm>
#include <numeric>
#include <iterator>
#include "boost/tuple/tuple.hpp"
#include "boost/tuple/tuple_comparison.hpp"
#include "boost/tuple/tuple_io.hpp"
using namespace std;
using namespace boost::tuples;
typedef tuple density;
int main()
{
vector<density> v;
istream_iterator<density> in(cin);
istream_iterator<density> eos;
ostream_iterator<density> out(cout);
density total;
copy(in, eos, back_inserter(v));
copy(v.begin(), v.end(), out);
cout << endl;
return 0;
}
Thanks
Kevin
