try

#define BOOST_VARIANT_NO_FULL_RECURSIVE_VARIANT_SUPPORT

MSVC++ 2010 and gcc maybe need this.

Hi

I try to use boost::recursive_variant with a recursive std::map.

There are several projects and examples on the internet using boost::recursive_variant exactly like I do and it seems to work there.

But somehow I can not make it compile in my environment. I am using gcc
4.6.1 and boost 1.46.1.

I've stripped my code down to this:
-------------------------------------------------------------
#include <boost/variant.hpp>
#include <map>

typedef boost::make_recursive_variant<
    int,
    std::map<float, boost::recursive_variant_>
>::type element;

int main ()
{
    element i = 42;
}
