I just tried to compile this code : http://www.boost.org/doc/libs/1_43_0/libs/property_tree/examples/debug_setti... It fails too. Is it a compiler bug?

Hi! I'm trying to use boost::property_tree but can't compile this simple code on VC10 :

#include <string> #include #include

const std::string CONFIG_FILE = "game.cfg";

int main() {        using namespace boost::property_tree;        ptree properties; // compilation error here

       //read_info( CONFIG_FILE, properties );

       return 0; }

The compilation log :

As I'm using a default ptree typedef that is already used in the tutorial, I think I might be doing something stupid but I can't find what. I tried that with boost 1.42 and 1.43, both failed. Any idea?

Thanks
