Running "freeze" on non-framework Python/universal binary issues
by Kevin Walzer July 21, 2006

July 21, 2006

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm trying to learn how to "freeze" an application that links against a non-framework build of Python. The basic mechanism works fine when I try a vanilla install of PPC Python 2.4 via Fink: /sw/bin/python freeze.py hello.py ...lots of messages make ....lots more messages ./hello Hello world... Kevin-Walzers-Computer:~/python24-fat/Tools/freeze kevin$ file hello hello: Mach-O executable ppc "freeze" is having problems with my non-framework "universal" build of Python 2.4, however. It seems to be gagging on the "arch" flags. Here's a typical error message: /usr/bin/ld: warning M_rfc822.o cputype (18, architecture ppc) does not match cputype (7) for specified -arch flag: i386 (file not loaded) I probably need to figure out a way to get the right flags passed on to "freeze" or "make" so that the i386 object files are built also; right now it's only outputting ppc files. Here's the command that runs: gcc -DNDEBUG -g -O3 -Wall -Wstrict-prototypes - -I/usr/local/python-unix/include/python2.4 - -I/usr/local/python-unix/include/python2.4 -c M_traceback.c Any advice? (I'm trying "freeze" because py2app doesn't seem to play nicely with non-framework builds, and I have no clue how to fix it.) - -- Kevin Walzer Poetic Code http://www.kevin-walzer.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEv7U1rTC5hIgjqTMRAi1kAKCKeL5DeE44ff873gSvdPMQnmt2BQCghN6W JFPOJi2dzH20pgNdmByZzI4= =Q1F6 -----END PGP SIGNATURE-----

ctypes for Intel-base Macs?
by Dethe Elza July 20, 2006

July 20, 2006

Hi folks, I'm trying to get ctypes working on my new Macbook Pro under Python 2.4. It works under Python 2.5beta, so I assume the porting work has been done somewhere, but does not work with the downloadable version of ctypes (libffi won't build): > configure: error: "libffi has not been ported to i686-apple-darwin8.7.1." I've tried getting libffi via darwinports, but it reports the same error: > configure: error: libffi has not been ported to i386-apple-darwin8.7.1. I've tried to find the libffi shared library in Python2.5 to see if I could build ctypes around that, but all I could find was _ctypes.so. Maybe I could build around that, but I don't know what pieces I need to copy over. Any ideas for how I can get a working ctypes under 2.4 would be appreciated. Thanks! --Dethe

Appscript does implement a built-in launch command: app('textedit').launch() However, it doesn't work at all right, so don't bother trying it. The only way I can currently think of doing it is to use AS: import osax osax.runscript('launch app "TextEdit"') If anyone knows how to launch apps without them being sent the customary run event then please let me know. has -- http://freespace.virgin.net/hamish.sanderson/

appscript equivalent of launch?

As far as I can see, appscript lacks an equivalent of Applescript's launch verb, which opens an app without running it (useful for apps like Textedit or Keynote that create default documents when they run).

py2app -- can't import os module?!
by Alan Liu July 20, 2006

July 20, 2006

Hi, I hoping someone might recognize this right away. I have no idea what's gone wrong. I have a wxPython app that works fine on python 2.3 (vendor) and py2app. Now I'm trying to get the same to work with python 2.4.3 and wxPython 2.6.xand py2app from pyobjc-1.4-python2.4-macosx10.4.dmg. It appears to build fine but I get a very strange error when I try to execute the standalone: 'import site' failed; use -v for traceback Traceback (most recent call last): File "./ImageDaemon.py", line 3, in ? import os zipimport.ZipImportError: can't find module 'os' Any hints?

To do "includes", you need to manipulate the modulegraph instance. Take a look at the docutils recipe for an example. 'packages' is in the return value because that need to be dealt with by py2app, not modulegraph. > Eventually it would be nice to figure out how to get these into > site-packages.zip, as uncompressed numpy is 5 MB, matplotlib is 10 > and scipy is 15.

Adding resource fork support to tarfile.py
by Apple Consultants Network July 19, 2006

July 19, 2006

Dear List, I am new to the list and new to python, so please be kind :) I've recently started playing with duplicity (http://duplicity.nongnu.org) and really like the feature set that is offered by the project. However, I am being stung by the thorn in Apple's side; resource forks. duplicity uses a copy of tarfile.py to build the tar archives. And since this file does not call OS X's tar, nor does it have support for resource forks, it will only add data forks to the tar archive. So, I started looking around and found that OS X has a tarfile.py (System/Library/Frameworks/Python.framework/Versions/2.3/lib/ python2.3/) as part of the standard python install. This tarfile.py is different from the one distributed by duplicity, and at first I though I would use it in the distribution. However, using this default install shows that it too does not respect resource forks. For example, doing a simple: #!/usr/bin/python import tarfile tar = tarfile.open("sample.tar", "w") for name in ["Arial"]: tar.add(name) tar.close() produces a tar file with only the data fork. The resource fork is lost. In the case of fonts, this is bad. I am currently running 10.4.7 so I know that resource forks are supported in many unix tools such as cp, mv, tar, and others. For example, if I execute a simple tar cf archive.tar Arial, the font is intact upon expansion, tar xvf archive.tar. Also, from searches, there appears to be some level on integration between python and resources forks on the Mac through the use of "import MacOS > from Carbon import Res". From searching the archives I've found some sample code to allow the reading of the contents of a resource fork (thanks to the poster for that). However, I need to make the tarfile library respect the forks as this is how duplicity creates the archive files. Has anyone figured out a way around this limitation in python' tarfile.py library. Admittedly, I generally avoided python so this is a bit foreign to me. Any help or even clarification would be appreciated. I realize that for a person new to the language, this is a tall order. Thanks for your time. Reid

Universal wxPython app fails when run on second (PPC) machine
by Erik Westra July 19, 2006

July 19, 2006

Hello, pythonmac folks. Thanks to all the hard work you guys have been doing getting Python to run on Intel, I have a wxPython application which runs beatifully on my MacBook Pro. I'm using the Framework build of Python 2.4.3 under OSX 10.4.6, with the "pre-release" universal wxPython version 2.6.3.2rc2. This works perfectly on the Intel machine, but I now have to create a standalone version of my system which also runs on PPC-based Macs. I downloaded and installed Bob Ippolito's py2app, version 0.2.5 from http://pythonmac.org/packages/py24-fat. To my pleasant surprise it worked first time, successfully building a standalone version of the application which runs on the Intel machine just fine. But when I try to copy the app and run it on a second (PPC-based) machine, the application crashes with the following error message: > Traceback (most recent call last): > File "/Users/erik/Desktop/Risk Reporter/Risk Reporter.app/ > Contents/Resources/main.py", line 57, in main > File "Framework.pyc", line 264, in run > File "main.py", line 82, in startup > File "main.py", line 21, in __init__ > File "library/utilities/wxUtils.py", line 388, in __init__ > File "Framework.pyc", line 122, in get > File "Framework.pyc", line 350, in _getPythonModule > File "library/Workbench/Workbench.py", line 30, in ? > File "Framework.pyc", line 134, in get > File "Framework.pyc", line 350, in _getPythonModule > File "library/Workbench/PythonShell.py", line 11, in ? > File "wx/py/__init__.pyc", line 8, in ? > File "wx/py/crust.pyc", line 15, in ? > File "wx/py/editwindow.pyc", line 8, in ? > File "wx/stc.pyc", line 10, in ? > File "wx/_stc.pyc", line 18, in ? > File "wx/_stc.pyc", line 11, in __load > ImportError: Failure linking new module: /Users/erik/Desktop/Risk > Reporter/Risk Reporter.app/Contents/Resources/Python/lib-dynload/wx/ > _stc.so: Library not loaded: /usr/local/lib/wxPython- > ansi-2.6.3.2rc2/lib/libwx_macd-2.6.0.dylib > Referenced from: /Users/erik/Desktop/Risk Reporter/Risk > Reporter.app/Contents/MacOS/../Frameworks/libwx_macd_stc-2.6.0.dylib > Reason: image not found I'm not sure if this is because the application is running under PPC, or if the application is trying to load /usr/local/lib/wxPython- ansi-2.6.3.2rc2/lib/libwx_macd-2.6.0.dylib, which just happens to be installed on the MacBook Pro but not on the PPC machine. Any suggestions for how to get this going? Do I need a later version of py2app, perhaps? Or can I add something to my setup.py script to force this library to be included in the bundled application? Thanks, - Erik.
