bdist_mpkg: more informative error message
by Ralf Gommers June 14, 2010

June 14, 2010

Hi, For numpy and scipy we use bdist_mkg to build dmg installers, and we had a user complain about a not so informative error message about a missing System Python. System Python means from python.org instead of Apple Python, so I can understand the confusion. You can find the details in http://projects.scipy.org/scipy/ticket/1177. I propose this fix for plists.py: 94c94,99 < title = u'%s requires %s to install.' % (pkgname, name,) --- > # System python can be interpreted as Apple Python, explain this better > if name.startswith('System Python'): > title = u'%s requires %s from www.python.org to install.' % (pkgname, > name[7:],) > else: > title = u'%s requires %s to install.' % (pkgname, name,) I hope this change can end up in the next bdist_mpkg version. Also, it would be helpful to have a correct email address on PyPi. I contacted Bob Ippolito, who referred me to this list or Ronald Oussoren (of whom I have no address). Best regards, Ralf Gommers

I have little time, but here is the short version: The goal is to get a PIL binary that is statically linked to all of its dependencies, and those dependencies are all universal (32 bit PPC and Intel) and linked against the 10.4 sdk (or even the 10.3 one...) I achieved all of this except for the 10.4 part... = Building the dependencies: = This ended up being trivial with macports: sudo port install jpeg +universal sudo port install lcms +universal sudo port install freetype +universal = Statically linking them when building PIL: = This is trickier -- it turns out that the PIL setup.py already looks in the macports tree for libs. However, gcc prefers dynamic linking, so out of the box, it will dynamically link the dependencies -- fine on your machine, but not re-distributable. I THINK there may be a way to tell gcc, through distutils, to statically link, but it's hard to find. However, if gcc only finds static libs, then it will link those. In this case, I wasn't using macports for anything else on that machine, so what I did is re-name /opt/local/lib, and then create a new one that had only static libs in it. then I just ran setup,py build and presto: all was well. The better way to do this would be to edit the setup.py to point to a place where the static libs are instead of mangling your macports install. One other note about 10.4 -- the last time I tried to build teh deps n a 10.4 machine, I had trouble -- I don't think there are a lot of macports devs on 10.4 any more, so it tends to be buggier. To create the package, run bdist_mpkg, you can get that with easy-install -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

Subject:, Could py2app bundle all the requirements of my package?
by Brendan Simon (eTRIX) June 6, 2010

June 6, 2010

I think the short answer is yes. I've had no trouble with py2app getting all my dependencies. You have a bigger app so it may need some extra tweaking, but py2app has lots of commands to include and exclude stuff. It is similar to py2exe from what I can tell.

Looking for pyapp guru for advice and possible functionality/bug fixing help
by Timothee BESSET June 3, 2010

June 3, 2010

Hello, We are looking to package and distribute a small python app that uses PyQt. We've had good success on Windows with py2exe, it's a very small app with one native module, and we end up with a package that's around 10 MB. I worked on obtaining the same packaging for the Mac with py2app, and the best I can get is something close to 100 MB. That would probably be fine if it was a larger application to begin with, but that's a hard sale for our little script. I'm hoping this can be reduced, but I'm not sure how to get there. Here's a bit of info on the setup: - OSX 10.5, targetting 10.5 and 10.6 using stock python (2.5 from Apple) - Qt libraries from http://qt.nokia.com/downloads/qt-for-open-source-cpp-development-on-mac-os-x (4.6.2 cocoa for OSX 10.5/10.6) - Installed and compiled the latest sip and PyQt from http://www.riverbankcomputing.co.uk/ (4.7.3) Questions: - Can I distribute only sip/pyqt etc., and have users do a one time standalone installation of the Qt package? - Can I skip the packaging of python itself, since I use stock Python 2.5 present on 10.5 and 10.6 releases? Beyond that I noticed a few issues while working with py2app .. I can go into more detail if there are developers here actively tracking py2app stuff.. TTimo

Python 2.7b2 framework install
by Michiel de Hoon June 2, 2010

June 2, 2010

Hi everybody, When I try to install Python as a framework: ./configure --enable-framework make make install then Python gets installed under /Library/Frameworks/Python.framework/Versions/2.7, but it doesn't seem to function as a framework: >>> import MacOS >>> MacOS.WMAvailable() False >>> Python 2.6.5 installed as a framework returns True here. With Python 2.7b2, my extension module (the MacOSX backend for matplotlib) doesn't interact correctly with the window manager; it works fine with Python 2.6.5. Did anything change in the installation of frameworks between Python 2.6.5 and 2.7b2? Thanks, --Michiel.

sys.path corrupted?
by Kevin Walzer June 2, 2010

June 2, 2010

I've been trying to test a new app I'm working on and it appears that my sys.path has been corrupted somehow, because Python doesn't see things in my site-packages directory. My $PATH is correctly set up: which python /Library/Frameworks/Python64.framework/Versions/Current/bin/python However, when I run this Python, I get this output: >>> import sys >>> sys.path ['', '/Users/kevin/Programming/phynchronicity/build/Phynchronicity.app/Contents/Resources', '/Users/kevin/Programming/phynchronicity/build/Phynchronicity.app/Contents/Resources/Modules.zip'] This specific path is the sys.path for one of my applications wrapped by bundlebuilder--not the expected one! Does anyone have any idea what might cause my framework build of Python to see sys.path only in the build directory of one of my apps? I don't typically jigger my Python settings with .pth files so I have no idea what to look for. TIA, Kevin -- Kevin Walzer Code by Kevin http://www.codebykevin.com

py2app, snow leopard, x86_64, ports
by Johan Gyllenspetz June 1, 2010

June 1, 2010

Hi, What is the status on py2app -> snow leopard -> x86_64 and ports. Do I really need to build all port packages with the flag +universal, it seems like it seems the application when inspected returns. file dist/dog.app/Contents/MacOS/dog dist/dog.app/Contents/MacOS/dog: Mach-O universal binary with 2 architectures dist/dog.app/Contents/MacOS/dog (for architecture i386): Mach-O executable i386 dist/dog.app/Contents/MacOS/dog (for architecture ppc): Mach-O executable ppc Is there a way to tell py2app to build the app for x86_64 instead thus solving the issue with having to build all port packages with the universal flag (which can be quite tricky). /Johan
