Boost::Property_Tree Settings

I am trying to configurate my XML file, thanks to Boost::Property_Tree. Chat I want is :

<configuration>
<message>
<first>10</first>
</message>
</configuration>

And what I have is :

<configuration><message>first>10</first></message></configuration>

I found that I had to use 

boost::property_tree::xml_writer_settings<char> settings(' ', 1);
write_xml(file, XMLobjectL, std::locale(), settings);

But this doesn't compile. Errors are :

IntelliSense: no instance of "write_xml" matches the argument list argument types are: (const std::string, boost::property_tree::ptree, std::locale, boost::property_tree::xml_parser::xml_writer_settings)

error C2664: 'void boost::property_tree::xml_parser::write_xml(const std::string &,const Ptree &,const std::locale &,const boost::property_tree::xml_parser::xml_writer_settings &)' : cannot convert argument 4 from 'boost::property_tree::xml_parser::xml_writer_settings' to 'const boost::property_tree::xml_parser::xml_writer_settings &'

Do you have any idea ? I am using Boost 1.57.0 and MVSC++ Thank you in advance.

You need to help overload resolution.

That said, consider using xml_writer_make_settings:

Live On Coliru

#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/xml_parser.hpp>

using namespace boost::property_tree;

int main() {
    ptree XMLobjectL;
    XMLobjectL.put("configuration.message.first", 10);

    write_xml("test.xml", XMLobjectL, std::locale(), xml_writer_make_settings<ptree::key_type>(' ', 1u));
}
