Packaged python .app file crashing, but packaged python .sh file working fine


I've produced an app using Python 3.4.3, Pyqt4 and some other extras (Poppler being among them) on OS X Yosemite.

I'm using cx_freeze to produce a working .app file and eventually, a working msi file. I've been testing the app works properly after building it using the build command as in "python3 setup.py build". This all works fine, no unexpected crashes. Moved on to packaging it using "python3 setup.py bdist_dmg". Opened the dmg file/app file, they crash instantly giving this error:

There's a load more but I'm not sure how much is relevant. Here is my setup.py file:

from cx_Freeze import setup, Executable
import sys
import os

base = None
if sys.platform == "win32":
    base = "Win32GUI"

zips = ["implementation/primaries/GUI/designer_files",
         "implementation/primaries/GUI/themes",     "implementation/primaries/GUI/images",
     "implementation/primaries/scripts"]
build_exe_options = {"packages": ["os"], "excludes": ["tkinter"],
                 "include_files":zips}


setup(
    name='FYP',
    version='0.1',
    packages=['implementation', 'implementation.primaries',     'implementation.primaries.GUI', 'implementation.primaries.scripts',
              'implementation.primaries.GUI.pyqt_plugins',     'implementation.primaries.Drawing',     'implementation.primaries.Drawing.classes',
          'implementation.primaries.Drawing.classes.tree_cls',     'implementation.primaries.ExtractMetadata',
              'implementation.primaries.ExtractMetadata.classes',     'implementation.primaries.ImportOnlineDBs','implementation.primaries.ImportOnlineDBs.classes'],
    description='MuseLib',
    options = {"build_exe": build_exe_options},
    executables = [Executable("implementation/main.py", base=base)]
)

Not sure what the problem is, I saw a few other people having similar problems but they seem to be on either older versions of Python or older versions of OS X, and the fixes didn't solve my problem. Any suggestions for how to proceed would be appreciated.


Solution

  • Found a better way to debug this: right click on the app file, "view package contents", MacOS > select the executable with the same name as the file given in setup.py (for me this was main). Error I then got: QWidget: Must construct a QApplication before a QPaintDevice

    I fixed this by initialising my Application object, then initialising my main window object, then showing the main window, and then calling a load method which set up the window. I was originally doing that part inside the constructor which was for some reason giving problems. I'm now having issues with opening/closing windows and opening others on close, but that's probably best for another question or session of googling.
