py2app and bdist_mpkg on Linux?
by Arne Babenhauserheide May 13, 2008

May 13, 2008

Hi, I am trying to get py2app and bdst_mpkg to work in Gentoo GNU/Linux at the moment, and I wondered, if you could provide some information. The problems I'm stumbling upon are: * plistlib isn't avaible in my Python. It can be downloaded from SVn, though: -> http://svn.python.org/view/*checkout*/python/trunk/Lib/plistlib.py?rev=60173 * Carbon.File isn't avaible in my Python either. I'd be very thankful for help in getting it to work (and I'll try to contribute the findings at least into Gentoo, so other Gentoo users can use py2app and bdist_mpkg, too).

Well Christopher, VERY GREAT!!! I've installed Universal PIL from your link, and now I've solved my initial problem. But now, I have another problem: when I launch my app, will raise an Exception managed from Apple Report. I attach this report thx very much PS: and debugging my app, I've found that the import xml.etree.cElementTree as cElementTree cause crash on running app... any ideas??? -- /\/\ariano Di Felice Java PHP Python Ruby programmer with MySQL, PostgreSql, SQLite and Oracle support Linux Platform Developer http://www.marianodifelice.it mariano.difelice(a)gmail.com Tel. 0735 703735 Cell +39 339 6407211

Folder Access Modes in Py2App Install
by Doug Fort, Consulting Programmer May 12, 2008

May 12, 2008

Hi, We use Py2App to distribute SpiderOak. We're getting complaints from users that when they install the product from an administrator account (which they must do to write to /Applications), they can't run the product from other accounts. Examination shows that the top level .app directory has access mode 755 $ ls -ld /Applications/SpiderOak.app/ drwxr-xr-x 3 dougfort admin 102 Mar 17 10:50 /Applications/SpiderOak.app/ However, lower level directories have access mode 700 $ ls -ld /Applications/SpiderOak.app/Contents/ drwx------ 7 dougfort admin 238 Mar 17 10:50 /Applications/SpiderOak.app/Contents/ When I run chmod -R 755 /Applications/SpiderOak.app/ I can run from the other users. Is there a way we can persuade Py2App, and/or setup to set these access modes? -- Doug Fort, Consulting Programmer http://www.dougfort.com

giving an embedded interactive interpreter access to objc & app objects
by Michael VanLandingham May 11, 2008

May 11, 2008

Hi, I'm working on a (mostly cocoa) application, and want to embed an interactive interpreter into the app. I think I have that working, at least in a Foundation-based test CLI app. (I'm sure it will be more difficult outside of the terminal environment). However, how do I give the interpreter access to the app's objects? Is there some way to pass those objects in, via PyObjC or something else, before calling the PyRun_InteractiveLoop() function? Or is there a way that I can take advantage of introspection to gain access to those objects once I've started the interpreter? There is pyobjc.inject, which seems to be able to do this kind of introspection etc, but it's not working for me on Leopard. Plus, I'd rather explicitly embed the interpreter, rather than the injecting voodoo. (I did try loading the example InjectInterpreter.bundle into my app, but that didn't work either). Thank You, Michael

py2app mac
by Mariano Di Felice May 9, 2008

May 9, 2008

Hi people! I have a problem about compiling my simple python script into a MAC app. I have installed Python 2.5, wxPython2.8.7.1, PIL 1.1.6. After, py2app from svn trunk version 0.4.2 I compile this on a mac PC Intel Minimac with OS Tiger version 10.4.11 This is my python source script: """ test.py """ import Image import os import sys import wx app = wx.PySimpleApp(0) Image.new("RGBA", (400,400) ) wx.MessageBox("ciao", "") app.MainLoop() and this is my setup.py script: from distutils.core import setup import os #includes=["PIL", "PIL._imaging", "PIL._imagingft", "PIL._imagingmath", "PIL._imagingtk", "Image", "PIL.Image"] #packages = ["PIL"] import py2app plist = {} setup(name='test', options={ 'py2app': { 'includes':includes, #'packages': packages, 'compressed': True, 'optimize': 2, 'plist': plist } }, version='0.1', app=["test.py"], setup_requires=["py2app"], ) Compilation works fine! But.... when I run my test.app into another MAC ( this is a MAC PPC Tiger without PIL, wxpython, etc etc ), I have more problems: if I don't include any package, I obtain: ImportError: The _imaging C module is not installed And if I include packages = ["PIL"] I obtain this exception from console: ImportError: No module named Image Why???? I'm desperate!!! thx very much -- /\/\ariano Di Felice Java PHP Python programmer with MySQL, PostgreSql and Oracle support Linux Platform Developer http://www.marianodifelice.it +39 339 6407211 0735 703735

py2app and eggs
by Christopher Barker May 7, 2008

May 7, 2008

Hi all, I'm having an odd issue with py2app. It seems to be bringing in almost everything in my Python install -- I"m getting a 112MB .app --which is way too big! The resulting app is crashing hard in a way I can't figure out anything about, too, but I don't know if that has anything to do with it. Anyway, do you suppose it is bringing in every egg I have installed? -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

python shell crash after 10.5 upgrade
by Garry Willgoose May 6, 2008

May 6, 2008

I've just moved all my stuff from a Intel Imac on 10.4.11 to a Macpro on 10.5.2. On both machines I have the same universal activestate python. I have some codes that build a shared library using f2py from numpy. Now when I import the library as built on osx10.4 it all works fine but when I import library as built on 10.5 I get the following error message willgoose-macpro:system garrywillgoose$ python ActivePython 2.5.1.1 (ActiveState Software Inc.) based on Python 2.5.1 (r251:54863, May 1 2007, 17:40:00) [GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import tsimdtm Fatal Python error: Interpreter not initialized (version mismatch?) Abort trap Its only my libraries that are the problem. I upgraded to the latest version of activestate 2.5.2 but same problem. Reinstalled all the compilers and the numpy support library ... still the same.

Is it broken? oops, sorry, I didn't tell you what to do with it! Drag and drop a *.jpg on it -- it should make a copy with "Watermark" printed in top, in the upper left hand corner.

After this, the PIL package installs fine. Yes, this installer is built for the python.org build, not the Apple one -- we could do that to, but I don't have 10.5, so I can't do it. > - Now I try to run the script by hand: > > $ python SimplePILTest.py SafetyGirl1-small.jpg > "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/PIL/ImageFont.py", > line 205, in truetype > return FreeTypeFont(filename, size, index, encoding) > File > "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/PIL/ImageFont.py", > line 121, in __init__ > self.font = _imagingft.getfont(file, size, index, encoding) > IOError: cannot open resource > > - It needs the font file, which isn't in there.

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

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. Thoughts? -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

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
