What is wrong with BOOST_FOREACH(const std::string &name, m_modules)?

[Demetrio.pepi]

I am trying to compile this example [url]http://www.boost.org/doc/libs/1_42_0/doc/html/boost_propertytree/tutorial.html[/url]
and I am getting the error "/usr/local/boost_1_47_0/boost/property_tree/detail/ptree_implementation.hpp:795:54: error: request for member ‘put_value’ in ‘tr’, which is of non-class type ‘bool’" in this line:

BOOST_FOREACH(const std::string &name, m_modules){
    pt.put("debug.modules.module", name, true);
}

My full error message is:

There is a version mismatch. The code for 1.47.0 would be:

BOOST_FOREACH( const std::string& name, m_modules )
{
   // pt.put( "debug.modules.module", name, true ) ;
   pt.add( "debug.modules.module", name, true ) ;
}

Thanks. It is running now.
