Thanks Dino - works great now. Runtime speed is much snappier when compiled.
One other thing I spotted is that pyc always builds a console app if /main
is specified.
elif arg.startswith("/main:"):
main_name = main = arg[6:]
target = System.Reflection.Emit.PEFileKinds.ConsoleApplication
Confused me for a bit :-) Have added this to Codeplex issue.
Cheers,Davy Mitchell
