# Hi,
# I understand that I have to create processing libraries which
includes my own processing objects. If I successfully compile and
install that library (using that scons script) they appear in the
object list of the Network Editor. Am I right? Then is it possible
that turning a .network patch to an standalone executable?

# I created three files in a directory. SConstruct, MyProcessing.hxx
and MyProcessing.cxx in a directory. Copied the lines from the wiki
page. And run the script. But get the errors below.
# I think I have to declare my own DataTypes. But is there a working
example which uses a native DataType, like Audio or Spectrum?
