Error with standalone wxpython app created with py2app

[Oksana Meledin]

I am trying to create a standalone Mac GUI app.

I used wxPython (wxpython-phoenix 3.0.3) to create the GUI.

I am trying to use py2app (0.14) to create a standalone app that can be used on a different machine not requiring a python installation.

The wxPython works fine by itself on the machine where it was created (MacOS Sierra, virtual environment in miniconda python).

I am able to compile the app using py2app, but the app does not work. When I run it from the command line, I get the following error:

Traceback (most recent call last):

2017-07-14 00:46:55.453 CtAnnotator[38476:1598471] CtAnnotator Error

Here's my build python script:

#!/usr/bin/env python

"""

build_CtAnnotator.py - script for building CtAnnotator

Usage:

    % python build_CtAnnotator.py py2app

"""

from setuptools import setup

import sys

# from distutils.core import setup

sys.setrecursionlimit(20000)

APP = ['CtAnnotator.py']

PACKAGES = ['wx', 'os', 'dicom', 'operator', 'cv2', 'numpy', 'cPickle']

OPTIONS = {'argv_emulation': True,

           'plist': {'PyRuntimeLocations': ['/opt/localdepth/localdepth/localdepth/localdepth/localdepth/localdepth/miniconda2/envs/app-env/lib/libpython2.7.dylib']},

           'packages': ['wx'],

          }

DATA_FILES = []

setup(app=APP,

      data_files=DATA_FILES,

      options={'py2app': OPTIONS},

      setup_requires=['py2app'],

     )

The reason for the deep miniconda installation is to avoid the  "Mach-O header is too large to relocate in" error.

See: http://py2app.readthedocs.io/en/latest/faq.html

Can someone help me figure out how to solve this problem?

Thanks!

Are you trying to run the binary in the same environment or a different machine?

Thank you.

Hi Igor,

Thanks for taking a look at my issue.

I'm trying to run it on the same machine for now. The eventual goal is to run it on a different mac without a python development environment.

I did take a look at  https://github.com/openai/universe/issues/139. The issue is similar to mine but not the same. I am not trying to "import universe". Rather I am doing "import wx".

As your app works OK with wx Python itself, you may get more help with the py2app part of it from the pythonmac-SIG list which often has discussions about py2app and its development.
