[fusion] fusion::map broken for Visual Studio 2005?
Attached is a simple repro (taken directly from the fusion::map documentation example). It fails to compile on Visual Studio 2005 using CVS HEAD from today the message below. Fusion::map solves a current problem I have rather elegantly but this is an obvious showstopper. Any ideas?

Hmm attachment didn't go through too well sending via outlook express and received here via Thunderbird. I've recreated it and pasted it below.

Did the way map works at some point get changed from fusion::at to fusion::at_key and the docs are just out of date? The code below seems to work. - Michael Marcin ---------------- #include <iostream> #include <string> #include <boost/fusion/support/pair.hpp> #include <boost/fusion/sequence/container/map.hpp> #include <boost/fusion/sequence/intrinsic/at_key.hpp> int main() { using namespace boost::fusion; typedef map< pair<int, char> , pair<double, std::string> > map_type; map_type m( make_pair<int>('X') , make_pair<double>("Men") ); std::cout << at_key<int>(m) << std::endl; std::cout << at_key<double>(m) << std::endl; return 0; }

Which docs are out of date? I've always been using at_key with fusion::map. Cromwell D. Enage __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

The docs at: CVS_HEAD boost/libs/fusion/doc/html/fusion/sequences/containers/map.html and http://spirit.sourceforge.net/dl_more/fusion_v2/libs/fusion/doc/html/fusion/... are out of date at least... although now that I look the usage of fusion::map in the quickstart section uses at_key. - Michael Marcin
I tried to compile the example from Michael on VC7.1 SP2. It gives my an error: test.cpp(19) : error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'boost::fusion::pair<First,Second>::second_type' (or there is no acceptable conversion) with [ First=double, Second=std::string ] Am I missing something here? Maybe a header file? Regards, Christian On 12/22/06, Michael Marcin <mike@mikemarcin.com> wrote:
