py2app issue with wx
by Agos Sept. 11, 2011

Sept. 11, 2011

Hi everybody! I hope somebody can help me :) I have this setup: Enthought Python Distribution 7.0-1 32 bit Which includes Python 2.7.1 Running on Mac OS X 10.6.8 My application, which uses - wx - matplotlib - numpy - scipy What I'm trying to do is to package it as a .app with py2app. The app gets packaged ok, runs fine on my Mac, but does not run on any other Mac (educated guess: it does not run on any Mac without the Enthought Python Distribution). Here is my setup.py: https://gist.github.com/1098405 Here is the ouput of the build command: http://dl.dropbox.com/u/365171/py2appbuildoutput.zip [warning, >1MB when uncompressed, do not open with Textmate ;)] The output of the build command looks pretty uneventful BUT the last line reports: error: can't copy '/Library/Frameworks/Python.framework/Versions/7.0/lib/python7.0/config/Makefile': doesn't exist or not a regular file which I don't know if is to be expected. Is it? Upon launch (on any Mac I've met beyond mine), this is the error I get: https://gist.github.com/1098413 Looking around I've found some cases of very similar errors: http://old.nabble.com/Problems-getting-started-with-py2app-and-wxPython-td2… https://groups.google.com/forum/#!topic/wxpython-users/ehI8ecZqDDI https://groups.google.com/forum/#!topic/wxpython-users/sdIaPG_K4s0 http://www.google.it/search?sourceid=chrome&ie=UTF-8&q=py2app+%22_core_.so%… The proposed solutions I've found are: 1) update py2app. I'm using py2app-0.6.3-py2.7.egg and altgraph-0.9-py2.7.egg (from homebrew) which are to my knowledge the latest versions currently available. 2) do not use the “stock” python, but rather download it from python.org. I can't use the python.org one, but I think the EPD python is sufficiently non-stock. Any idea? I'm afraid I can't provide a minimal example to reproduce the problem. I'll try to build one this weekend. Until then, the code is here: https://github.com/Agos/BeatingModeSW (the only things missing are the aforementioned setup.py, the app icon and the good old ez_setup.py). A binary showing the problem is here: http://dl.dropbox.com/u/365171/bmgui.zip [warning: 40 meg download]. Any help is very appreciated. Regards, A. P.S. I tried just now to add 'includes': ['wx'], but there was no difference.

translate applescript to appscript
by Adam Morris Aug. 12, 2011

Aug. 12, 2011

I have an AppleScript snippet that I need translating to python appscript; too low-level for ASTranslate to handle: tell application "Finder" "/Users/brainysmurf/Desktop" as POSIX file as alias end tell I'm writing a wrapper class for the Finder and want to be able to pass /path/to/doc to its methods and so I need a way to convert from paths to file objects that the Finder can do things with. Reading the docs I tried: appscript.app("Finder").AS_newreference(appscript.app.elements('psxf').byname('/Users/brainysmurf/Desktop')) But I get an error saying that elements is not an attribute. I get the same deal with appscript.app('Finder'). Using appscript 1.0.0 Help? -Adam

OS X 10.7 Lion, py2app 0.6.3, argv-emulation, wxPython
by Florian Höch Aug. 5, 2011

Aug. 5, 2011

In 10.7, some functionality of the Carbon libraries is only available in 32-bit mode, but py2app created binaries run in 64-bit mode on Lion. In my case wx and py2app's argv-emulation feature needed Carbon functionality that isn't available in 64-bit mode, so I did work around this by replacing the binaries with 32-bit ones after the app was created. First, I used the official python.org Python 2.7 x86-64/i386 installer. Then I built my app with the 32-bit python: python2.7-32 setup.py p2app Then I replaced the binaries in the app: cp /Library/Python/2.7/site-packages/py2app-0.6.3-py2.7.egg/py2app/apptemplate/prebuilt/main-i386 /PATH/TO/APP/APPNAME.app/Contents/MacOS/APPNAME cp /Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-32 /PATH/TO/APP/APPNAME.app/Contents/MacOS/python Just thought I'd share my findings.

Issue with QTKit + CoreVideo usage
by Damiano ALBANI July 29, 2011

July 29, 2011

Hello, In the context of prototyping a GStreamer plugin, I'm trying to use the QTKit API in Python to capture from a video source. On the overall, it works, I can grab frames and save them as files for instance. Now, I'd like to access low-level frame data but I didn't managed to do it in Python. I've uploaded a simple test case on "http://pastebin.com/kyhggtWM". Here are the kind of messages that I get, each time the function "captureOutput_..." is called: ... 2011-07-28 18:01:51.101 Python[446:580b] PyObjCPointer created: at 0x1033103d0 of type {__CVBuffer=}@@ 2011-07-28 18:01:51.102 Python[446:580b] *** Ignoring exception: Class OC_PythonObject: no such selector: _cfTypeID ... Any idea what I'm doing wrong here? I'm new to the world of PyObjC so I might be forgetting to import stuff or something trivial like that. BTW, I'm using Mac OS X 10.6.8. Thanks, -- Damiano ALBANI

Python for Tiger PPC I found your wonderful page at <http://pythonmac.org/packages/py25-fat/index.html> that has numpy and PIL for Tiger, which I can't find anywhere else, but I'm trying to run pymapper <http://pymapper.com>, which requires Python 2.6 or later (but not Python 3). Do these binaries exist anywhere? Or am I stuck trying to figure out how to build them? Thanks! Jim

I believe older versions' EULAs still apply to those versions, and it's my understanding that VMs are not allowed for older versions, except using server versions of OS X. I'm not an attorney, and I'm intending this as a caution and not legal advice. I would recommend carefully reading the relevant EULAs and/or consulting an attorney before running any version of OS X in a VM. Cheers, Josh

py2app application fails with ImportError: No module named sysconfig
by Russell E. Owen July 23, 2011

July 23, 2011

I used py2app to build an application that i've been building for years, only now it's failing at startup with the appended log. The problem is triggered by numpy 1.6.1fc3 (which I installed from source). If I build using an older numpy I don't see the problem. However, the application runs just fine from the command line, so I'm puzzled how it could be an actual bugin numpy. (If it is, though, now is a great time to report it, before 1.6.1 is released). Any idea what might be causing this and how to avoid it? A google search didn't turn up anything that looked relevant. -- Russell Traceback (most recent call last): File "/Applications/TUI.app/Contents/Resources/runtuiWithLog.py", line 76, in <module> File "/Applications/TUI.app/Contents/Resources/lib/python2.7/TUI/Main.py", line 70, in <module> File "/Applications/TUI.app/Contents/Resources/lib/python2.7/TUI/BackgroundTas ks.py", line 33, in <module> File "/Applications/TUI.app/Contents/Resources/lib/python2.7/RO/Astro/Tm/__ini t__.py", line 23, in <module> File "/Applications/TUI.app/Contents/Resources/lib/python2.7/RO/Astro/Tm/EpJFr omMJD.py", line 2, in <module> File "/Applications/TUI.app/Contents/Resources/lib/python2.7/RO/Astro/llv/__in it__.py", line 11, in <module> File "/Applications/TUI.app/Contents/Resources/lib/python2.7/RO/Astro/llv/etrm s.py", line 9, in <module> File "/Applications/TUI.app/Contents/Resources/lib/python2.7/numpy/__init__.py ", line 155, in <module> File "/Applications/TUI.app/Contents/Resources/lib/python2.7/numpy/ctypeslib.p y", line 58, in <module> File "/Applications/TUI.app/Contents/Resources/lib/python2.7/numpy/distutils/_ _init__.py", line 7, in <module> File "/Applications/TUI.app/Contents/Resources/lib/python2.7/numpy/distutils/c compiler.py", line 7, in <module> File "distutils/ccompiler.pyc", line 21, in <module> ImportError: No module named sysconfig

I note that Lion EULA now permits use of up to 4 instances of the OS running in Virutal Machines, so you be able to use OS X (10.6 or 10.5 or 10.4) in a VM (VirtualBox, Parallels, VMWare, etc) to do your PowerPC builds ??
