py2app and .so files
by André Sintzoff March 8, 2011

March 8, 2011

Hello, I'm trying to create a py2app application built for TortoiseHg (https://bitbucket.org/tortoisehg/thg/wiki/Home). The goal is to provide a Mac OS X stand alone application for TortoiseHg. The application is created with: $ python setup.py py2app --use-pythonpath Unfortunately, when $ open ./dist/TortoiseHg.app/Contents/MacOS/TortoiseHg the following message is displayed ImportError: '/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/mercurial/osutil.so' not found I'm wondering why the application searches modules in /System/Library/Frameworks/Python.framework and not in the bundle just created where the files are available. $ ls ./dist/TortoiseHg.app/Contents/Resources/lib/python2.5/lib-dynload/* ./dist/TortoiseHg.app/Contents/Resources/lib/python2.5/lib-dynload/PyQt4: Qsci.so QtCore.so QtGui.so ./dist/TortoiseHg.app/Contents/Resources/lib/python2.5/lib-dynload/mercurial: base85.so diffhelpers.so osutil.so bdiff.so mpatch.so parsers.so How to tell to the application to use bundled .so files? Thank you André

Python compatible with GC?
by Kevin Walzer March 3, 2011

March 3, 2011

I'm trying to debug a crash in a Python/Tkinter application that I am unable to reproduce using equivalent Tcl/Tk code. I have a custom Tcl/Tk extension library that implements an NSToolbar for Tk windows (using Tk-Cocoa). In testing this extension, when I call the standard Cocoa dialog to save a file, Python then crashes with a segfault. Ordinarily these kinds of issues are reproducible in Tk itself using Tcl/Tk itself, since the crash pertains to some bug in Tk. However, I am not able to reproduce this issue with Tcl/Tk, just with Python/Tkinter. This leads me to suspect the issue may lie somewhere within the interaction between Python and Tk. My build of Python is 2.7.1, built as 64/32-bit, and linked to the system Tcl/Tk Cocoa frameworks (for Mac App Store compatibility). Tcl/Tk is built with garbage-collection enabled; could this cause some issue with Python, which I believe does not support Objective-C-based GC? Here is my crashlog below.

missing wrapper for an NSView method?
by Kaz Wesley March 2, 2011

March 2, 2011

The Cocoa docs describe a reflectScrolledClipView: method for NSView in "OS X 10.0 and higher": http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Appli…: But when I do this: >>> from AppKit import NSView >>> NSView.reflectScrolledClipView_ I get an AttributeError. Am I overlooking something, or is this a missing-wrapper-method bug?

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.

[SOLVED] How to exclude py2app Pygame icon
by Rob Leachman March 1, 2011

March 1, 2011

As often happens, forming confusion into an intelligible question yields the solution. I'll share my finding and would appreciate any feedback. This hack seems a lot of bother but any other fix evades. The issue was stated nicely some time ago, see http://www.mail-archive.com/pythonmac-sig@python.org/msg08548.html as desired. The follow-up reply (add --resources AppIcon.png) doesn't seem to help. Looks like this list has a tradition of revisiting this topic on an annual basis (ha) and I didn't see another answer. My question was the same as OP, how to recreate the .zip after hacking on it, today the attached seems to do the trick and at the expense of just a bit more work producing the .app: Recreate the problem: hg clone https://RobertLeachman@bitbucket.org/RobertLeachman/pythentene hg clone https://RobertLeachman@ bitbucket.org/RobertLeachman/pythenteneassets cp pythenteneassets/stuff/setup_mac.py pythentene cp pythenteneassets/stuff/gameIcon.icns pythentene/stuff cd pythentene python setup_mac.py py2app Works fine, produces dist/Pythentene.app but has the issue at hand: the Pygame icon flashes on the dock as the game starts. cd dist/Pythentene.app/Contents/Resources/lib/python2.6 mkdir x; cd x; unzip ../site-packages.zip; cd pygame rm pygame_icon* cp ../../../../../../../../stuff/gameIcon.icns pygame_icon.icns cd .. zip -r9 site-packages-new.zip * cd .. mv x/site-packages-new.zip site-packages.zip rm -rf x Success, no more pygame icon but instead a nice stable experience for the user. I'm sincere about wanting to talk about the subject line, but also can't resist... this is all go-forward from the 0.1a release of http://www.bitblaster.com/pythentene/ and I'm hungry for help or feedback. Let me know if you are interested in some open-source programming work, or just play this classic game and complete the survey if you will. Thanks!
