If you read the Getting Started Guide or study the examples, you 
will see that the code catches and prints xml_schema::exception
to get more information about the error. If I change your code
to wrap the call to the parsing function into this try-catch
block:

  try
  {
    ...
  }
  catch (const xml_schema::exception& e)
  {
    cerr << e << endl;
  }

And try to run it on your sample GML documents, I get:

./hello_gml polygon.gml
:0:0 error: unable to resolve host/address 'aneto.oco'

./hello_gml point.gml 
:0:0 error: unable to resolve host/address 'aneto.oco'

./hello_gml line.gml  
line.gml:2:393 error: schemaLocation does not contain namespace-location pairs


You may want to read Section 5.1, "XML Schema Validation and Searching"
in the Getting Started Guide for some background information on this.

I also noticed that the examples refer to the WFS-basic.xsd schema
which is not compiled in your test application.

You can reduce it (along with the generated code size) by specifying
the --root-element-none option for most of your schemas.
