Hi, I'm trying to use py2app on an open-source program that I basically understand the workings of, but didn't write.
I've tried "python setup.py py2app" several times, but it doesn't work. I get error messages like the one below, when I click on the resulting app icon:
An unexpected error has occurred during execution of the main script IOError: [Errno 2] No such file or directory: '-psn_0_42205185
Where do I start? I really don't know the principle behind the setup.py file, what it does, what py2app does, what needs to be in setup.py for things to work, etc. How can I tell? I've checked out a few of the sample files, but I don't see how they apply to my situation. The program uses wxPython if that matters. I'm using OSX 10.3.7 and Python 2.3.
I'm not an experienced programmer, but I can learn fast. It's just hard without documentation. (Maybe py2app is intended for people that already know what they're doing) Anyways, I'm glad py2app is out there for people. Ok, thanks a lot for anything to help get me started.
py2app doesn't have documentation yet[1] because I haven't had the time and interest to write it. I'm more interested in implementing the features on my TODO list right now. I released it because it's very useful and much better than the poorly documented and much more fragile and incorrect alternative(s). If someone else writes such documentation, I will gladly accept it.
In your specific case you are trying to use a script that expects command-line arguments. Mac OS X's LaunchServices does not provide command line arguments useful to anything but the Carbon/Cocoa runtimes, so you have two choices:
(a) don't use sys.argv
(b) use py2app with --argv-emulation, which will hide the -psn argument from Python and will convert any dropped files into command-line arguments.
[1] python setup.py py2app --help does yield some usage information, and there are quite a few examples between the py2app and PyObjC sources.
