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.

eliminating appscript-triggered Dock icon (was: Re: Sending files to the trash)

The command line python interpreter automatically upgrades to a full GUI process whenever OS APIs linked to the Window Manager are called. In appscript's case, it uses the Carbon Process Manager to launch applications and obtain their process IDs. This behaviour is useful when running scripts that need to display dialogs, etc. to users, but it's a nuisance the rest of the time and is something I'd like to get rid of if possible. I'm stuffed for spare time at the moment, but if anyone else fancies rewriting the relevant code then do let me know.

locating Python.h
by Feat May 19, 2008

May 19, 2008

Hello: I need help to locate Python.h for including in a C program which I will turn into a module. The problem is I've accumulated 5 files with that name over the years: /Developer/SDKs/MacOSX10.3.9.sdk/System/Library/Frameworks/Python.framework/Versions/2.3/include/python2.3/Python.h /Developer/SDKs/MacOSX10.4u.sdk/System/Library/Frameworks/Python.framework/Versions/2.3/include/python2.3/Python.h /Library/Frameworks/Python.framework/Versions/2.4/include/python2.4/Python.h /Library/Frameworks/Python.framework/Versions/2.5/include/python2.5/Python.h /System/Library/Frameworks/Python.framework/Versions/2.3/include/python2.3/Python.h Since the executable Python I use is in /Library/Frameworks/Python.framework/Versions/2.5/bin, I thought I better use the corresponding include file [i.e. the 4th one in the list above] but this gets me fatal errors at link time: /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: Undefined symbols: _main _PyArg_ParseTuple _Py_BuildValue _Py_InitModule4 collect2: ld returned 1 exit status What am I doing wrong? What's the best way to clean up that mess? Can somebody help me? -- Jym Feat ~ Paris FR 75018

Dependencies for Python packages on OS-X
by Christopher Barker May 2, 2008

George Nurser wrote: > Apologies for perhaps raising an old chestnut here.... but these > issues would not arise if we had separate intel and ppc MacPython > binaries. But all sorts of other issues would arise. The tricky bit to all of this is getting/building Universal versions of the various dependencies. I still have no idea why Apple doesn't just provide a few more common libs, like libpng and libfreetype (which is now included with X11, but as I understand it, that's an optional install). Anyway as we don't have any control over what Apples does (and even less control over what they have already not done!), we need other solutions: My proposal: We try to build a consensus among the MacPython community about a "standard" way to deal with common dependencies. There is now more-or-less a consensus that we should provide binaries for MacPython (and now 10.5's Apple python) that are statically linked against universal versions of all the dependencies. That works great, but the truth is that it's a pain in the $$%#@ to get those dependencies built right, so we've substantially raised the barrier for folks to build binary packages. Also, it seems a bit silly to separately deal with something like libpng for multiple packages. I think I've got at least four python extensions with libpng. For example: Fredrik Lundh recently asked on the PIL list for recommendations as to what binaries he should provide for OS-X, and for someone to build them (he doesn't have a Mac). I set out to do it for him, and am still mired in dependency heck. Note that the key dependencies are the same as for Matplotlib (libpng, libfreetype) My proposal for the "standard" way to provide the libs: Kyng Chaos (William Kyngesburye)'s Frameworks: http://www.kyngchaos.com/wiki/software:frameworks He's got UnixImageIO, which provides libpng and others, and freetype, plus a bunch of others. They are all build as proper versioned OS-X frameworks, as well as a nice little hack where he puts soft links in to create a standard "unixy" hierarchy, so that they can be used by libs that don't understand frameworks. Yes, it's a bit extra to tell folks to first install these two frameworks, then whatever the python package lib is, but I think it really would make it easier all around, particularly for package builders, and making things easier for package builders means that more binaries would be built properly, which would make things easier for users. Note: William's Frameworks are all versioned properly, so there would be no harm in installing them multiple times, or having multiple versions installed. In fact, I think you could build a *.mpkg that had both your python package and the frameworks it needs, so that users would have a one download and one click install. It wouldn't hurt to have multiple packages with the same Frameworks installed this way.

py2app and matplotlib
by Christopher Barker May 1, 2008

May 1, 2008

Hi all, I'm having trouble getting py2app to work with matplotlib. There is a matplotlib recipe, but it's out of date, and some things have changed. The first error I got was not being able to find pytz.zoneinfo. As that's in a different place now, I commented it out of the matplotlib.py recipe. However, now I'm getting an error that I don't even know how to begin to solve: ... File "build/bdist.macosx-10.3-fat/egg/macholib/MachO.py", line 106, in load_header hdr = MachOHeader(self, fh, offset, size, magic, hdr, endian) File "build/bdist.macosx-10.3-fat/egg/macholib/MachO.py", line 146, in __init__ self.load(fh) File "build/bdist.macosx-10.3-fat/egg/macholib/MachO.py", line 178, in load raise ValueError("Unknown load command: %d" % (cmd_load.cmd,)) ValueError: Unknown load command: 27 > /Users/cbarker/HAZMAT/SmallToolsSVN/phCalculator/trunk/build/bdist.macosx-10.3-fat/egg/macholib/MachO.py(178)load() Enclosed is about the simplest matplotlib script, and a test_setup script to py2app it -- anyone have any ideas? -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

Xcode 3.0 and Compiled Python Files?
by Brian Berliner April 28, 2008

April 28, 2008

I'm playing around with the Python support in Xcode 3.0 (under Leopard). I'd like to have my built app include only .pyc (or .pyo) files and not to include the .py source files. 1. Is this possible? 2. How do I do it? 3. Is there a way to obfuscate the code so that it is not easy to disassamble? Thanks! -Brian

Nested app bundles
by Gary Bernhardt April 25, 2008

April 25, 2008

I want to split my app into multiple independent .apps, but I don't want the user to have to care about that. I could just stick one app inside another's Contents/Resources, but that effectively doubles the total size. Both apps would have full copies of the Python binary, standard library, etc. Is there some way to trick the two apps into using the same binary and standard library? Or is there some other method I'm not seeing? -- Gary http://blog.extracheese.org

non-framework Python 2.5.2 has empty lib-dynload
by Gary Poster April 24, 2008

April 24, 2008

Hi. I'm assuming this is a python-on-mac oddity, but maybe I'm wrong. I wanted a local non-framework build of Python 2.5.2. I did the following in a Python 2.5.2 source download: ./configure --prefix=/Users/gary/opt/py25 LDFLAGS=-L/opt/local/lib OPT=-I/opt/local/include make make install (The LDFLAGS and OPT are there to get readline and zlib from Darwin Ports in the Python.) I got some warnings about expat, but nothing serious during configure and make. But oddly, /Users/gary/opt/py25/library/python2.5/lib-dynload was completely empty. So, for instance, I couldn't do basic things like ``import math``. I then did make test. A few unrelated things failed--expat related, for instance--but most tests passed, including math tests. In fact, the .so files were in the build directory. I then did the following: ln build/lib.macosx-10.3-i386-2.5/*.so ~/opt/py25/lib/python2.5/lib- dynload/ Now everything seems to work. :-D :-/ Anybody know if I did something wrong? Or is this a bug in the Python 2.5 build? I couldn't find a similar report with Google, but maybe I wasn't looking in the right metaphorical corner. Gary

Is there a run-time way to tell if you're running fink, macports, etc?
by Christopher Barker April 24, 2008

April 24, 2008

Hi all, sys.platform returns "darwin" for all of the various python builds on OS-X. I"d like to know if I"m running a framework build, or fink, or macports, or whatever build -- is there a runtime way to do that? Is looking at sys.executable the best(only?) way? -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

Problem with File dialog
by Brett Duncan April 22, 2008

April 22, 2008

Hello List! I'm trying to add a file selector to a program I'm working on (I'm using wxPython on an Intel MacBook Pro, OS X 10.4.11), but I keep getting the following error whenever I run the program and try selecting a file: Traceback (most recent call last): File "ConvertGUI.py", line 56, in SelectFile if dialog.ShowModal() == wx.ID_OK: File "//Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/wx-2.8-mac-ansi/wx/_windows.py", line 707, in ShowModal return _windows_.Dialog_ShowModal(*args, **kwargs) wx._core.PyAssertionError: C++ assertion "filterIndex == 0 || !isName" failed at /BUILD/wxPython-src-2.8.7.1/src/mac/carbon/filedlg.cpp(162) in MakeUserDataRec(): incorrect format of format string Can anyone tell me what the problem is/where I've screwed up/how to fix this? Thanks, Brett
