[Pythonmac-SIG] ImportError when trying to open app made with py2app

[Terry Jones]

Greetings. I'm new at all things Python, so I hope the following is not too
naive or annoying. I've spent time looking for an answer - in the archives
(2005 only), on the web, etc., and also tried passing additional things to
py2app.

I am trying to wrap up some simple python code with py2app to distribute it.
My setup.py is trivial

    from distutils.core import setup
    import py2app

    setup(
	app=['examiner.py'],
    )

Running

  $ python setup.py py2app

appears to work fine, with exit status 0, output attached. I can then cd
into the dist directory and open the app successfully.

But when I open a finder window and double click on the app, I get an
error (the following is pasted from the console):

    ===== Wed Sep 28 2005 ===== 14:19:26 Europe/Madrid =====
    Traceback (most recent call last):

    ImportError: Failure linking new module: libqt.3.dylib: dyld: /Users/terry/mds/terry/xx/dist/examiner.app/Contents/MacOS/examiner can't open library: libqt.3.dylib  (No such file or directory, errno = 2)

Can anyone tell me what the problem is here? When I look in the dist dir, I
can see the following Qt relevant files:

    $ find dist -name '*[qQ]*' -print
    dist/examiner.app/Contents/Frameworks/libSoQt.20.dylib
    dist/examiner.app/Contents/Resources/Python/lib-dynload/pivy/gui/_soqt.so
    dist/examiner.app/Contents/Resources/Python/lib-dynload/qt.so
    dist/examiner.app/Contents/Resources/Python/lib-dynload/qtcanvas.so
    dist/examiner.app/Contents/Resources/Python/lib-dynload/qtgl.so
    dist/examiner.app/Contents/Resources/Python/lib-dynload/qtnetwork.so
    dist/examiner.app/Contents/Resources/Python/lib-dynload/qtsql.so
    dist/examiner.app/Contents/Resources/Python/lib-dynload/qttable.so
    dist/examiner.app/Contents/Resources/Python/lib-dynload/qtui.so
    dist/examiner.app/Contents/Resources/Python/lib-dynload/qtxml.so

So py2app has clearly found the use of Qt and included some libraries. But
the missing libqt.3.dylib which it's looking for is not present. I do have
this, in /usr/local/qt/lib:

    $ ls -la /usr/local/qt/lib/libqt*        
    -rwxrwxr-x    1 root     terry     9907224 Jun  9 18:12 /usr/local/qt/lib/libqt.3.3.4.dylib
    lrwxrwxr-x    1 terry    terry          17 Jun  9 18:12 /usr/local/qt/lib/libqt.3.3.dylib -> libqt.3.3.4.dylib
    lrwxrwxr-x    1 terry    terry          17 Jun  9 18:12 /usr/local/qt/lib/libqt.3.dylib -> libqt.3.3.4.dylib
    lrwxrwxr-x    1 terry    terry          17 Jun  9 18:12 /usr/local/qt/lib/libqt.dylib -> libqt.3.3.4.dylib
    -rw-rw-r--    1 root     terry         707 Jun  9 17:21 /usr/local/qt/lib/libqt.la
    -rw-rw-r--    1 root     terry         714 Jun  9 17:21 /usr/local/qt/lib/libqt.prl

If the above information is not sufficient, I'll happily send more details
of my setup (OS X 10.3.9, python 2.4, etc). I'm not sure that they matter
though, seeing as I can manually do a successful open from the dist
directory.

Thanks for any help,
Terry Jones
