Re: [Jython-users] freezing an application with pythonc? Do Python packages work?

[Samuele P. <pe...@in...>]

You have encountered a bug,
a workaround is to define
a startup.py:

import TopLevel.mainmodule

and then jythonc --core --deep --jar whatever.jar startup.py

but depending our needs this can be useful or  not.

Let us know.

regards, Samuele Pedroni.
