How to make py2app app stub link to Cocoa framework?
by Kevin Walzer March 31, 2013

March 31, 2013

I've been trying to get one of my Python-Tk applications to integrate with Lion's sandboxing framework (for Mac App Store submission) and have been having difficulty. Based on some feedback I received in the Apple Developer forums, it appears that part of the issue is that the executable stub created by py2app does not link to the Cocoa frameworks. A quick run of otool -L confirms this: Kevin-Walzers-MacBook:~ kevin$ otool -L /Users/kevin/Programming/quickwho/cbk/QuickWho.app/Contents/MacOS/QuickWho /Users/kevin/Programming/quickwho/cbk/QuickWho.app/Contents/MacOS/QuickWho: /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 832.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.10) Is there any way I can get this executable linked to /System/Library/Frameworks/Cocoa.framework? I didn't think install_name_tool would do the trick, as that just rewrites links, rather than adding them. A Any suggestions are appreciated. --Kevin -- Kevin Walzer Code by Kevin http://www.codebykevin.com

py2app and PyQt: QT plugins cause loading multiple QT library versions
by Michael McCracken Nov. 28, 2012

Nov. 28, 2012

New user, so new thread, in reference to "(PyQt and py2app) Gui starts in IDLE but not as app". This happens when Qt loads image plugins from the system location (likely set during Qt's configure), which then load the system Qt. The problem and a workaround are described here: http://lists.trolltech.com/qt-interest/2008-09/thread00258-0.html py2app's PyQt sample doesn't exercise enough of Qt to hit this problem. I'm not sure exactly what part of Qt you'd need to trigger it, but I guess the Color Picker might work. The quick way, if you know you don't need these plugins, is to create an empty qt.conf file at MyApp.app/Contents/Resources/qt.conf. The plugin search path can be set in that qt.conf, or an empty one just stops it from looking for plugins. I've verified that an empty file avoids the issue, haven't tested setting the path. For py2app, I guess some thought is required for a nice API to handle this case, since these are C dylibs that won't be detected at bundle time. Ideally, we could have an option that takes a list of qt plugins we need, and creates the appropriate qt.conf. There isn't a quick way to add this in, so I thought I'd ask for comments on how it should be designed. I will probably need plugin support soon, and I'd like to be able to contribute the change back. Thanks, -mike

Trouble building against Tkinter on 64-bit python.org python
by Russell E. Owen Nov. 14, 2012

Nov. 14, 2012

I'm on MacOS X 10.6.8 using 64-bit Python 2.7.2 from python.org (the 10.6 version) and ActiveState Tcl/Tk 8.5.10. I would like to build matplotlib 1.1.0 (in fact I'd like to build an official binary installer) and am running into problems. The build and install goes fine, though with a few odd messages (see appended log). But importing pylab rusults in: objc[1083]: Class TKApplication is implemented in both /Library/Frameworks/Tk.framework/Versions/8.5/Tk and /System/Library/Frameworks/Tk.framework/Versions/8.5/Tk. One of the two will be used. Which one is undefined. objc[1083]: Class TKMenu is implemented in both /Library/Frameworks/Tk.framework/Versions/8.5/Tk and /System/Library/Frameworks/Tk.framework/Versions/8.5/Tk. One of the two will be used. Which one is undefined. objc[1083]: Class TKContentView is implemented in both /Library/Frameworks/Tk.framework/Versions/8.5/Tk and /System/Library/Frameworks/Tk.framework/Versions/8.5/Tk.

Google turned up others with this problem but no obvious solution. -- Russell P.S. partial log of build (not install) of matplotlib: Edit setupext.py to point it to Apple's built-in libraries, plus

py2app - building under 10.6.8, running under 10.4?

by Geoffrey Irving Sept. 24, 2012

Sept. 24, 2012

I am trying to package up a mixed Python/C++ application using py2app. My setup.py is from setuptools import setup setup(app=['voxpopuli.py'],data_files=[],options= {'py2app'{'argv_emulation':True}},setup_requires=['py2app']) and I invoke py2app via python setup.py py2app --no-strip --iconfile /Users/irving/otherlab/other/bin/OLicon.icns --resources /opt/local/lib/Resources/qt_menu.nib This completes without warnings or errors, but when I try to run the resuling app a window pops up that simply says "voxpopuli Error". It has an "Open Console" button, but the only console messages are 9/21/12 11:43:14.691 AM voxpopuli[52765]: voxpopuli Error 9/21/12 11:43:15.926 AM com.apple.launchd.peruser.501[158]: ([0x0-0x177d77c].org.pythonmac.unspecified.voxpopuli[52765]) Exited with code: 255 Are there standard ways to get more information out of py2app to help diagnosing this error? Thanks, Geoffrey

packaged .app creating site.pyo and others, breaking code signature
by Michael McCracken Sept. 20, 2012

Sept. 20, 2012

I've been getting occasional issues where my code signature is invalid because python has written .pyo files inside the app bundle. Specifically it's writing UbuntuOne.app/Contents/Resources/site.pyo and a bunch of files in the one package that isn't included in my .zip, for example: UbuntuOne.app/Contents/Resources/lib/python2.7/configglue/schema.pyo This is confusing, because I'm not setting 'optimize' in the py2app options. I looked into the py2app bundle template, and I see in main.c where it sets PYTHONOPTIMIZE based on the info.plist PyOptions dict. My Info.plist has optimize = 0, and if I print os.environ in my main script, I see 'PYTHONOPTIMIZE': '0'. OK, so then I print sys.flags immediately afterwards, just as a sanity check, and I get this: sys.flags(debug=0, py3k_warning=0, division_warning=0, division_new=0, inspect=0, interactive=0, optimize=1, dont_write_bytecode=0, no_user_site=0, no_site=0, ignore_environment=0, tabcheck=0, verbose=0, unicode=0, bytes_warning=0, hash_randomization=0) Note the optimize=1. That looks like the culprit, but I'm kind of stumped as to where that's getting set. Any ideas? On a related note, I tried to set sys.dont_write_bytecode = True at the top of my main script, and it still writes the .pyo files. I imagine I could run the app once before signing it, but that's not ideal for automated builds. Thanks for any help, -mike

ImportError, no suitable image found (app not running under 10.5)
by Paul Wiseman Sept. 18, 2012

Sept. 18, 2012

This app runs fine on 10.6 and 10.7, but when I run it on 10.5 I an apple error report, and the following error in console Traceback (most recent call last): <some traceback> ImportError: dlopen(/Applications/TestApp.app/Contents/Resources/lib/python2.7/lib-dynload/_librsync.so, 2): Library not loaded: @executable_path/../Frameworks/librsync.1.dylib Referenced from: /Applications/TestApp.app/Contents/Resources/lib/python2.7/lib-dynload/_librsync.so Reason: no suitable image found.

I have both Xcode 3 and 4 installed and I have the 10.5 SDK, I'm just not sure about how I can compile the extensions I need to use it?

py2app unable to find cprocessors.so
by Paul Wiseman Sept. 14, 2012

Sept. 14, 2012

Hey, When building an app that is using sqlalchemy I get this error: creating python loader for extension 'sqlalchemy.cprocessors' error: /Users/paul/Source/Python/build/bdist.macosx-10.6-intel/python2.7-standalone/app/temp/sqlalchemy/cprocessors.py: No such file or directory I took a look in site packages and there is no cprocessors.py, but a cprocessors.so - so maybe it is just looking for the wrong extension I tried adding "sqlalchemy.cprocessors" to the includes list in py2app but that hasn't helped. I was wondering if I can fool it by dropping an empty cprocessors.py so it will build, then swap it out afterwards for the so, but I'm sure there's a better way and I'm not convinced that could even work. Surely py2app doesn't assume every extension is .py, or if it does can it be changed?

Tkinter/Mac newbie query
by William R. Wing (Bill Wing) Sept. 11, 2012

Sept. 11, 2012

Mac OSX 10.8.1, 2 x quad processor Intel MacPro, Python 2.7.3 from python.org. I've been programming in python for a couple of years (off and on), and I'm getting more and more comfortable with it. I'd like to start putting GUIs in front of some of my code, and have been looking at wx, Tkinter, and PyQt. Everything I read says that starting with Tkinter version 8.2 (or something like that) it is "themed" and Tkinter applications should look native on the various platforms. The version of Tkinter I have is 8.5, but when I code up some of the Tkinter demos, they all come out looking more like X11 applications than like native Mac apps. I assume the problem is because I'm not doing SOMETHING right in the initialization, but I'm scratching my head over what. Does anyone have any thoughts as to what I might be doing wrong? I've pasted a typical bit of code in below. #!/usr/bin/env python from Tkinter import * class App: def __init__(self, master): frame = Frame(master) frame.pack() self.button = Button(frame, text="QUIT", fg="red", command=frame.quit) self.button.pack(side=LEFT) self.hi_there = Button(frame, text="Hello", command=self.say_hi) self.hi_there.pack(side=LEFT) def say_hi(self): print "hi there, everyone!" root = Tk() app = App(root) root.mainloop() And yes, the version of python I get via !usr/bin/env is the same one I get at the terminal prompt. Thanks, Bill
