Any idea what's happening?

The drawing.bmx isn't the programs source code, more like a include/import for the tutorials in the same directory..
Those errors are typical when this

Type MyApp Extends wxApp
End Type

New MyApp.run()

is missing..

Try running pdfdocument.bmx instead... it imports all the other examples, which should then generate all the example pdfs.
