I don't have any direct experience with PyInstaller and cygwin. I see that "os.name" is being set within os.py, and it uses a heuristic based on sys.builtin_module_names. Specifically, if it finds the builtin module "posix", it sets os.name = "posix"; if it finds the builtin module "nt", it sets os.name = "nt". So my guess is that Popen() is invoking a different interpret than those you are expecting. Can you show us your Popen() line? Do you use shell=True or shell=False? You should investigate on what Python version is being run. Priting sys.executable and sys.version at the beginning of your scripts might get you on track. -- Giovanni Bajo Develer S.r.l. http://www.develer.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "PyInstaller" group.
