a little bit further, but even failed to compile:

// from qt logger context
     int ctx_line =42;
     const char *ctx_file = "the_file.cpp";
     const char *ctx_function = "the_function";

// string_literal expected
// errror: no matching function for call to 
'boost::log::v2s_mt_posix::attributes::named_scope_entry::named_scope_entry(const 
char* const&, const char* const&, const int&)'
// how to convert ??
attributes::named_scope_entry scope(ctx_function, ctx_file, ctx_line);

// error: no matching function for call to 
'boost::log::v2s_mt_posix::attribute_value_set::insert(const char [6], 
boost::log::v2s_mt_posix::attributes::named_scope_entry&)'
record.attribute_values().insert("Scope", scope);

The first lacks probably my missing knowledge about const char* and 
const char[], isn't it?

Thanks,
