Python 3. OS/X 10.6 Ipython
by John Riordan April 9, 2011

April 9, 2011

I am trying to get IPython running with Python 3.1 on OS/X 10.6.3. The install script for IPython configures it to run with Python 2.6. Is there a way around this?

C++ ABI 1002/102 incompatibility with wxPython
by Brendan Simon (eTRIX) March 1, 2011

March 1, 2011

I have a wxPython app that is built with py2app. A user recently reported the following error when trying to run the app. Fatal Error: Mismatch between the program and library build versions detected. The library used 2.8 (no debug,Unicode,compiler with C++ ABI 1002,wx containers,compatible with 2.6), and your program used 2.8 (no debug,Unicode,compiler with C++ ABI 102,wx containers,compatible with 2.6). Abort trap logout It appears to be a difference in the wx libraries on the target system and the wx libraries on the build system. Unfortunately, at this stage, I do not know what the OS X version is on the target system. The app was built using Python 2.5.4, (wxPython 2.8.11.0 or 2.8.4.2 ??) on OS X 10.6.6. Is there anyway to fix this with a py2app setting ?? Doesn't py2app copy all the libraries to the app bundle ?? I guess that doesn't guarantee that the libraries will load on any OS. What about path settings ?? I presume others have solved this before. Any suggestions ?? Many thanks, Brendan.

[py-appscript] is System Events sleeping ?
by Fandekasp Feb. 2, 2011

Feb. 2, 2011

Hello, I'm a new user of appscript, and I can't find a way to know when my computer is sleeping or not. with : > from appscript import * app("System Events").sleep() I can force my system to sleep, but what I would like is to know when my system is going to sleep, to launch some routines behind (like programming an alarm to ring after 6 hours). I searched for an argument who could tell me this, but didn't find any. Is it at least possible ? Thank you very much for your help Best regards

Jan. 29, 2011

Hello there, I am trying to run a python program on my Mac OS X Version 10.5.8. The program makes use of the pygtk module. I successfully downloaded the module (pygtk) and on trying to install it using the "python setup.py install', I got a new error: ImportError: No module named dsextras I have tried in vain to look for the latter module(dsextras)... any one with some hint? Thank you in advance, Muthoni

How to get a Mac OS X version of Tcl/Tk rather than X11 version.
by Lou Pecora Jan. 27, 2011

Jan. 27, 2011

I have an installation of Python 2.6.4 on my MacBook Pro (OS X 10.6) that by default uses X11 windows and dialogs rather than the Mac version of those GUI items. In my googling and exchanges on other support groups I've come down to the problem may be with the Tcl/Tk installation using the "generic" X11 GUI rather than the Mac version. Does anyone know how I can change that in the Tk part of the python framework? I think this problem came up in the iPython email list, but I didn't get enough info from the messages there. More Info: The python framework is part of the SAGE package which I installed from source. I did this on my Mac Pro (system 10.4) and it works well with Mac windows for matplotlib and Mac open/save dialogs for Tk calls. But on my MacBook Pro I get X11 windows and dialogs. I want the Mac versions. Even more info: If you're interested, below is the original message I put up on the SAGE support group and was told it's a problem with the type of Tcl/Tk installed. -- Lou Pecora, my views are my own. ---------------------------------------------------------------------------------- I have an installation of SAGE (from source) on my Mac laptop in which using the tcl/tk library to plot (using TKAgg backend) or call tk file open/save dialogs calls the X11 versions and not the native Mac versions of dialogs and windows. I want to get the Mac versions. I posted about this on this list recently and now after a response here and much googling I have the sense that the problem is that I have a SAGE package with an X11 version of the tk library rather than the Mac one. I compiled SAGE from source on my Mac laptop. That went perfectly. I don't know how I got the X11 version since I also compiled SAGE from source on my Mac desktop where the plotting and file dialogs are the correct Mac versions, not X11. The only difference is that the laptop is Mac OS X 10.6 and the desktop is 10.4. If that matters, I don't know. Does anyone know how to get the Mac version installed in the SAGE source-compile installation? I have not found an answer to this elsewhere. I'm hoping someone here knows how this is done with the source installation. Thanks for any help or pointers. -- Lou Pecora

Determining if I need an import
by Chris Weisiger Jan. 27, 2011

Jan. 27, 2011

I've inherited a large codebase that is practically the definition of "legacy", with all that entails. I've spent a lot of time removing unused code, renaming variables, creating classes, moving global variables to locals (let's stuff all our program state into a single module and then just import that whenever we want to access it!), and so on, and now I want to start cleaning up the dependency chains between different modules. There's several places where I've had to move an import statement from being at the top of the module to being inside a function right before it's used, to prevent circular dependencies from causing imports to fail at program start. I wouldn't be surprised if I've rendered many of these imports moot, but short of a fair amount of painful grepping across ~20k lines of Python, I don't know of an easy way to find them. Is there a tool that examines your actual and apparent dependencies? I know there are programs that will generate dependency graphs, but for those there's little difference between a tight coupling and a single import statement that isn't actually needed. (Though if you'd care to recommend a dependency graph generator, I'd like to hear about that too) -Chris

py2app -- ouch!
by michael ferraro Jan. 25, 2011

Jan. 25, 2011

Hello all and thanks for listening! I have scanned the archive and the web for current practices in packaging an Mac Python app with py2app. I have been successful before (i.e circa python 2.4 and Mac OS X 10.4). I am now working on under 10.6.6 and python 2.6.6.18 as shipped with the OS. I am using PyQt 4.8.2. as an i86_64 app. It runs fine from the terminal as python Teatro.py I used easy_install-2.6 -U py2app which retrieved and installed py2app 0.5.2. I used a couple of variation of what seem to be standard procedure to create the app including /Library/Frameworks/Python.framework/Versions/2.6/bin/py2applet --make-setup --alias --argv-emulation Teatro.py followed by: python setup.py py2app python setup.py py2app -A as well as /Library/Frameworks/Python.framework/Versions/2.6/bin/py2applet Teatro.py the setup.py file looks like this: """ This is a setup.py script generated by py2applet Usage: python setup.py py2app """ from setuptools import setup APP = ['Teatro.py'] DATA_FILES = [] OPTIONS = {'alias': True, 'argv_emulation': True} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], ) when I try to run the app (Teatro.app or dist/Teatro depending on which procedure I used to build it) i get this: The console reports: 1/22/11 8:44:43 PM com.apple.launchd.peruser.501[420] ([0x0-0x51051].org.pythonmac.unspecified.Teatro[899]) Exited with exit code: 255 1/22/11 9:16:30 PM [0x0-0x5e05e].org.pythonmac.unspecified.Teatro[982] Traceback (most recent call last): 1/22/11 9:16:30 PM [0x0-0x5e05e].org.pythonmac.unspecified.Teatro[982] File "/Users/mef/Development/-Applications-/Teatro/Teatro.app/Contents/Resources/__boot__.py", line 103, in <module> 1/22/11 9:16:30 PM [0x0-0x5e05e].org.pythonmac.unspecified.Teatro[982] _argv_emulation() 1/22/11 9:16:30 PM [0x0-0x5e05e].org.pythonmac.unspecified.Teatro[982] File "/Users/mef/Development/-Applications-/Teatro/Teatro.app/Contents/Resources/__boot__.py", line 101, in _argv_emulation 1/22/11 9:16:30 PM [0x0-0x5e05e].org.pythonmac.unspecified.Teatro[982] _get_argvemulator().mainloop() 1/22/11 9:16:30 PM [0x0-0x5e05e].org.pythonmac.unspecified.Teatro[982] File "/Users/mef/Development/-Applications-/Teatro/Teatro.app/Contents/Resources/__boot__.py", line 40, in mainloop 1/22/11 9:16:30 PM [0x0-0x5e05e].org.pythonmac.unspecified.Teatro[982] stoptime = Evt.TickCount() + timeout 1/22/11 9:16:30 PM [0x0-0x5e05e].org.pythonmac.unspecified.Teatro[982] AttributeError: 'module' object has no attribute 'TickCount' 1/22/11 9:16:30 PM Teatro[982] Teatro Error When I build using python setup.py py2app Teatro.py without alias and argv_emulation in the setup.py /usr/bin/strip: for architecture x86_64 object: /Users/mef/Development/-Applications-/Teatro/dist/Teatro.app/Contents/Frameworks/Python.framework/Versions/2.6/Python malformed object (load command 3 cmdsize not a multiple of 8) stripping saved 333408 bytes (8961700 / 9295108) as the last line of the build and in the build directory i get dist.macosx-10.5-intel/ but away get the same result as above when I try to run the app I am sure it is obvious what is wrong but I have reach a dead end.

Python development on OSX
by Tony Cappellini Jan. 25, 2011

Jan. 25, 2011

Hello everyone, I've been doing Python development on Windows for several years, and now I will also be trying this on OSX. After getting my Macbook Pro, I've updated the os/software, then tried updating to Python 2.7. No knowing there are so many places to get the core Python installer for OSX, a friend had suggested that I install the Macports installer for 2.7 That installed fine, and I ran the command line that put that as the default Python to execute. I also use wxPython and want to continue developing wx apps on the Mac. When I tried running the installer for wx, a message was displayed indicating the postflight script had problems (I do have some info about the specifics of that problem somewhere, but it's not handy at the moment). So-my initial questions are... 1. Why are there so many "variations" of the Python installer for the Mac? (I'm not referring to 32-bit vs 64-bit architectures, although that does complicate things quite a bit). For example, there is the OSX installer at Python.org, then there are the Macports python variations, and I recently read about something called Macpython. How does one know which o to use? Thanks

Installing modules with py2app
by Mier, Alejandro Jan. 20, 2011

Jan. 20, 2011

Hello I have a script that installs Python, and then installs some modules with: subprocess.call("python setup.py install") The script works on Windows with py2exe, but gives me this error when using py2app: File setup.py from distutils.core import setup ImportError: No module named distutils.core I tried explicitly including distutils when building the .app bundle, with python setup.py py2app --packages distutils (and several variations of --includes), but then I get this error: error: invalid command 'install' What do I need to do to make this work on mac? Thanks!
