I'm trying the make_map example from the doc, nearly verbatim :

#include <boost/fusion/container/generation/make_map.hpp>
#include <boost/fusion/include/make_map.hpp>

int main() {
using namespace boost::fusion;
make_map(
make_pair<int>('X')
, make_pair<double>("Men"));
}

Both msvc9 and g++ 4.4.1 tell me that there is no make_map function that
takes two parameters. g++ mentions that it sees a parameter-less
make_map(). I use Boost 1.40.

What's up ?

Thanks,
J-L

This function is not documented correctly.
The correct usage of fusion::make_map is

fusion::make_map<Key0,...KeyN-1>(Value0,...ValueN-1)

Fixed. Thanks for noticing.
