MACOSX_DEPLOYMENT_TARGET with Leopard system Python
by Anand Patil July 31, 2008

July 31, 2008

Hi all, This languished on comp.lang.python, sorry about the cross-post. I'm getting the following error: distutils.errors.DistutilsPlatformError: $MACOSX_DEPLOYMENT_TARGET mismatch: now "10.3" but "10.5" during configure on Leopard using system Python when trying to compile some third-party modules but not others. I've set MACOSX_DEPLOYMENT_TARGET to 10.5 to no avail. It looks like lots of people have seen similar problems, but the fixes seem to involve running configure, which means a new Python build. Is it possible to fix the problem and still use the system Python? Thanks, Anand Patil

Thanks for the responses, I am trying to build a data structure in Python which exceeds 4GB in size (I have 10GB of RAM) and python exits with the following error when it hits 4GB: Python(23121) malloc: *** vm_allocate(size=262144) failed (error code=3) Python(23121) malloc: *** error: can't allocate region Python(23121) malloc: *** set a breakpoint in szone_error to debug My hope is that Leopard ships with a 64-bit version of Python, so that I can at least fill up the 10GB of RAM that I have.

Re: [Pythonmac-SIG] newbie Mac switcher trying to set up django on Intel MacBook Pro Tiger

Now that there are several people that want to support Apple's build of python: how do we go forward from here? I think we should start a small project for "MacPython Addons", this project will install: * Hotfix for distutils to ensure that distutils builds univeral binaries (32-bit only at first) * (possibly) hotfix to ensure that you can install '-fat-' eggs on 10.5 * /Applications/Python-2.5/IDLE.app In there future we could add other changes, such as a 'python64' command for running python in 64-bit code. IMHO this should be done only when we have patches python.org tree that enable 4-way universal builds on Leopard, otherwise we'd have a real risk of loosing these changes in a future version.

Is there still a good reason for separate macpython and pyobjc mailing lists?
by Jack Jansen June 3, 2008

June 3, 2008

Now that pyobjc is a first-class citizen of MacPython, is there any reason to maintain two mailing lists? Are there any people who are on one of the lists and not the other? -- Jack Jansen, <Jack.Jansen(a)cwi.nl>, http://www.cwi.nl/~jack If I can't dance I don't want to be part of your revolution -- Emma Goldman

Problem with CoreGraphics and py2app
by João Leão June 2, 2008

June 2, 2008

Hi I'm running Mac OS X 10.5.2 on a G4 MacBook and I didn't install any addons in what concerns Python. I was happy to see that apple is now including PyObjc and py2app. I tried to build applications with py2app from my old CoreGraphics scripts (made on 10.4 / python2.3) that used to work ok. py2app actually creates the application but when I run it, it unexpectedly quits. The Console spits this: 5/23/08 7:12:19 PM [0x0-0x85085].org.pythonmac.unspecified.Teste[647] Fatal Python error: Interpreter not initialized (version mismatch?) 5/23/08 7:12:36 PM com.apple.launchd[66] ([0x0-0x85085].org.pythonmac.unspecified.Test[647]) Exited abnormally: Abort trap Trying to exclude some error in my script, I tried this with one the Apple supplied examples under /Developer/Examples/Quartz/Python/. I ran py2app with the following "setup.py" (I chose the example "circle.py"): ### from distutils.core import setup import py2app setup( name='Test', app=["circle.py"], ) ### Incidentally, I discovered that my system isn't finding py2applet too: ibook-joao:Desktop joao$ py2applet --make-setup circle.py -bash: py2applet: command not found Finally, py2app seems to work ok with other scripts that don't use CoreGraphics. Thanks. João

Trouble installing Tkinter with 2.3.5/10.2
by Anthony Kozar June 1, 2008

June 1, 2008

Hello, I am a new member of the list and I joined because I am having trouble installing Tkinter with 2.3.5 on OS X 10.2.8. I have Jack's MacPython 2.3.5 installed and I downloaded and installed TclTk Aqua 8.4.6 today. But when I run the MacPython Package Manager, it displays an HTTP 404 error for the URL of the repository (some subdirectory of www.python.org/packman). In fact, I get a 404 error in my browser for that parent directory too, so it appears that all of the support for this Package Manager app is gone (??). I searched the wiki and mailing list and could discover no other repositories nor any recent information on alternatives. I am trying to develop a cross-platform GUI for an existing program written in Python. My machines run 10.2 and 9.1. It's a shame that this program requires Python 2.3 which has no Tkinter support on OS 9 or I would just use MacPython-OS9 2.2. I would also just upgrade my 10.2 machine to a newer Python but all of the 2.4 and 2.5 binary distributions appear to require 10.3. Is this correct? So I am wondering what my options are now for cross-platform GUI development with Python on 10.2? Can I get Tkinter installed somehow? Would wxPython work better? I am hoping for a solution that will be reliable and easily installed on Windows, Linux, and OS X. Thanks very much for your thoughts.

I'm not on the PyObjC list, but only because I've not had much need to ask PyObjC-related questions to date. Neither list is high traffic so consolidating them into a single mailing list wouldn't be a problem. Doing so would reduce fragmentation of available resources, and provide OS X users with a clear, one-stop destination for obtaining Python-related help.

shed skin vs macpython 2.5.2
by Gary Robinson May 29, 2008

May 29, 2008

Hello, I recently started using Shed Skin, which is a Python-to-C++ compiler. It works great. On the functions I converted, I got an 18X speedup. However, at the time I did that work I was running the Python Apple supplies with Leopard. Last week I installed MacPython 2.5.2. Now, whenever I try to load a Shed Skin-generated module I immediately get Traceback (most recent call last): File "<stdin>", line 1, in <module> SystemError: dynamic module not initialized properly However, i can still run it under the Apple python just fine, by invoking usr/bin/python. I asked about this on the Shed Skin mail list and haven't gotten a response yet. Thought I'd ask about it here just in case anyone has an idea.
