[Pythonmac-SIG] Trouble getting py2app to create self-contained app bundles

[Dave Peterson]

Hello,

I've been having a lot of trouble getting py2app (version 0.3.6) to 
create truely self-contained app bundles.  I'm thinking that either I'm 
doing something so obviously wrong, or else py2app doesn't really create 
self-contained bundles.

I've tried using it in both Apple's standard Python framework 
environment (launch python via /usr/bin/python, site-packages in 
/Library/Python/2.5/site-packages, etc.) and in an EPD Python framework 
environment (installs to 
/Library/Frameworks/Python.framework/Versions/4.3.0).

Here's what I'm doing.  Does anyone see something wrong?

Create a directory tree:
    /home/dpeterson/temp/
       setup.py
       test/
          __init__.py
          main.py


The setup.py looks like this:
    from setuptools import setup, find_packages
    setup(
        name='test',
        version='0.1',
        packages=find_packages(),
        entry_points = dict(
            console_scripts = [
                "test = test.main:main",
                ], 
            ), 

        # py2app stuff
        app = ['test/main.py'],
        options = dict(py2app = dict(
            extension = '.app',
            )),
        setup_requires = ['py2app'],
        )  


The test/__init__.py is an empty file and test/main.py looks like this:
    def main():
        print "Hello, world!"
   
    if __name__ == "__main__":
        main()


I then delete any pre-existing build and dist directories, then run 
"python setup.py py2app" which outputs a lot of stuff, but doesn't 
report any errors, and then try to run the generated app bundle's 
executable via "dist/test.app/Contents/MacOS/test" -- it runs and prints 
"Hello, world!" as expected.

BUT there is no Python.framework inside the generated app bundle under 
the "dist" directory.  And indeed, when I look inside 
dist/test.app/Contents/Info.plist, I see the following lines which seems 
to imply the bundle is falling back on the Python.framework version 2.5 
installed in a system location.

    <key>PyRuntimeLocations</key>
    <array>
        
<string>@executable_path/../Frameworks/Python.framework/Versions/2.5/Python</string>
        
<string>/System/Library/Frameworks/Python.framework/Versions/2.5/Python</string>
    </array>


Can anyone see what I'm doing wrong?  I want to ensure my distributed 
app bundle is self-contained and will continue to work even when Apple 
stops shipping Python 2.5.  Actually, I'd ideally like to use EPD to 
build my app bundle then have it work even if that version of EPD isn't 
installed on my co-workers machines.  But I'd be happy to solve the 
problem with Apple's python first.

Thanks in advance!
