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.

by Praveen Aug. 29, 2011

Aug. 29, 2011

Some system info before proceeding further: Platform: Mac OS X 10.7.1 Python Version: ActiveState Python 2.7.1 wxPython Version: [url= http://downloads.sourceforge.net/wxpython/wxPython2.9-osx-2.9.2.1-cocoa-py2… ] I want the button label to be changed while performing a task So, here is what I did/want: self.run_button=wx.Button(self.panel,ID_RUN_BUTTON,label='Install') self.Bind(wx.EVT_BUTTON, self.OnRun,id=ID_RUN_BUTTON) def OnRun(self,evt): self.run_button.SetLabel('Installing..') #call a function that does the installation task installation_task() #After task completion, set the button label back to "Install" self.run_button.SetLabel('Install') When I try doing this, it doesn't set the label to "Installing" while the task is being performed. Any suggestions how do I achieve this? -- Have a nice day !!!

PyObjC and signal handling
by Vinay Sajip Aug. 29, 2011

Aug. 29, 2011

How does PyObjC deal with signals received by an application? If I run a windowed PyObjC application, I can't interrupt it with Ctrl-C (this is on Leopard). I know this is no big deal, since I can always use Cmd-., but there are instances where a signal might be sent programmatically to a process. In such cases, a Python-installed signal handler would not be invoked if the application is inside C code waiting for events, until it returns from C back to Python code - potentially a long delay if no other events arrive for a while. There appears to be code in the PyObjC codebase to deal with it (e.g. installMachInterrupt) but I can't see how it gets called. It appears to use a C-level library called _machsignals, which I can't find on the system. Is this particular functionality in PyObjC no longer used? Thanks for any pointers, Vinay Sajip

installation trouble
by Paul Patterson Aug. 27, 2011

Aug. 27, 2011

I'm trying to install py-appscript to work with Python 3.1. My first attempt didn't exactly fail, rather py-appscript installed itself to work with the version of Python pre-installed on my computer (Python 2.6 on macbook pro running snow leopard). In an effort to get it working with 3.1, I then downloaded distribute 0.6.19 and appscript 1.0, moved them both to the directory where python 3.1 is installed. I installed distribute then tried to install appscript. After spewing out a ton of error messages, it ended with the line "error: command 'gcc-4.0 failed with exit status 1". Thinking it maybe had something to do with gcc (though I've no idea what gcc is), I ran the command: export CC=/usr/bin/gcc-4.0 Unfortunately It still didn't work and returned another error message (see attachment for screenshot). Can anyone tell me what my next step should be?

Running PyObjC projects after installing 3.3 for testing
by Vinay Sajip Aug. 26, 2011

Aug. 26, 2011

I've installed Python 3.3 for some testing on a Leopard machine, and now a 2.x PyObjC application won't run from its bundle because the 3.3 binary in /Library/Frameworks/Python.framework is picked up. Of course if I run python MyBundled.App/Contents/Resources/main.py the system Python (2.5.1) is used, but running MyBundled.App/Contents/MacOS/MyBundled runs with Python 3.3 and, of course, fails because the 2.5 site-packages used aren't found. Short of removing the 3.3 installation (which I still need for testing), how does one configure things so that the /Library/Frameworks/Python.framework binary is skipped and the system Python picked up? I've failed to find the appropriate info via Google, since "bundle", "path" etc. are seemingly too generic to home in on any posted info on the topic. I've considered that it might be a build-time thing, but looking at XCode (3.1.4) preferences, I can't see how to specify a particular Python to use. Thanks, Vinay Sajip

Does py2app work with PyPy? Has anyone tried it?

New Mach-O header is too large to relocate
by Erik Myllymaki Aug. 19, 2011

Aug. 19, 2011

I'm trying to make an app on a MB Pro with Snow Leopard(10.6.7) - and keep getting this error: "New Mach-O header is too large to relocate" A quick search found a suggestion about how to fix this: http://www.danplanet.com/home/82-codemonkeying/88-using-py2app-with-gtk basically, in this file: /opt/local/share/macports/Tcl/port1.0/portconfigure.tcl change this line: default configure.ldflags {-L${prefix}/lib} to: default configure.ldflags {"-L${prefix}/lib -Xlinker -headerpad_max_install_names"} and reinstall all macports packages. While this fix has allowed the build process to get further along, it still ends up failing with the same error eventually. Any advice greatly appreciated.

Python on iphone for developers
by Alex Jouravlev Aug. 18, 2011

Aug. 18, 2011

Hi, Sorry if misplaced. I am trying to find some information Is there a port of Python to iPhone? I want to be able to check-out from SVN, edit and run some Python server code now and then. I know iOS is a closed ecosystem, however as Developer one can build and install virtually anything on their iPhone. All you need is source code compatible with iOS (preferably 2.7) Thank you, Alex

Ownership of installed Python on Mac
by Michael Foord Aug. 18, 2011

Aug. 18, 2011

Hey folks, I've installed Python on OS X Lion on two computers - one with Lion preinstalled and one upgraded from Snow Leopard. I used both Python.org and Activestate installers. In all cases (I'm pretty sure) the installation required elevation and the installed Python was 'owned' by root - meaning any changes (e.g. installation into site-packages) must be sudo'd. This is a change from previous versions of OS X. Is this known, and is it an issue? (I chown'd everything back to me to get round it.) All the best, Michael -- http://www.voidspace.org.uk/ May you do good and not evil May you find forgiveness for yourself and forgive others May you share freely, never taking more than you give. -- the sqlite blessing http://www.sqlite.org/different.html

Python bridgesupport issue on Lion
by luke skywalker Aug. 18, 2011

Hi, I have Mac OS X Lion 10.7 running. I'm trying to use bluetooth with python. I've installed the lightblue library as it seems to be the only way to have easy access to bluetooth through python. However, when I do: import lighblueI get this:Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Python/2.7/site-packages/lightblue/__init__.py", line 160, in <module> from _lightblue import * File "/Library/Python/2.7/site-packages/lightblue/_lightblue.py", line 27, in <module> import _IOBluetooth File "/Library/Python/2.7/site-packages/lightblue/_IOBluetooth.py", line 47, in <module> globals=globals()) File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/objc/_bridgesupport.py", line 142, in initFrameworkWrapper _parseBridgeSupport(data, globals, frameworkName) File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/objc/_bridgesupport.py", line 42, in _parseBridgeSupport objc.parseBridgeSupport(data, globals, frameworkName, *args, **kwds)ValueError: cftype for 'IOBluetoothDeviceInquiryRef' must include gettypeid_func, tollfree or bothLooking at: /System/Library/Frameworks/IOBluetooth.framework/Versions/A/Resources/BridgeSupport/IOBluetooth.bridgesupportNo cftypes declared in it have a gettypeid function or a tollfree. Anybody knows what's wrong? I've checked other bridgesupport files and they also have the same pattern (cftypes without gettypeid or tollfree).Thx.
