Python 3. OS/X 10.6 Ipython
by John Riordan April 9, 2011

April 9, 2011

I am trying to get IPython running with Python 3.1 on OS/X 10.6.3. The install script for IPython configures it to run with Python 2.6. Is there a way around this?

MySQLdb on OS X 10.6
by Brian Zambrano Oct. 31, 2010

Oct. 31, 2010

Hi all, Like many others before me, I'm banging my head against the wall trying to get MySQLdb working on my new MacBook Pro with Snow Leopard. I have MySql 5.1 x86_64 installed, configured and running. I'm building MySQLdb 1.2.3c1 like this: export ARCHFLAGS='-arch x86_64' python setup.py build python setup.py install But it simply doesn't work....and apparently I'm not the only one<http://bit.ly/3iQy2> : (eb)brianz@eb-brianz$ python -c "import MySQLdb" Traceback (most recent call last): File "<string>", line 1, in <module> File "MySQLdb/__init__.py", line 19, in <module> import _mysql ImportError: dlopen(./_mysql.so, 2): no suitable image found.

Weird Carbon: gestalt: wxPython issue/bug
by Christopher Barker Oct. 13, 2010

Oct. 13, 2010

Hi folks, Peter Hanson, on the wxPython list, seems to have identified a bug in the gestalt module, that may be a Carbon issue. It's a bit of an unusual case: it freezes up wxPython, when wx is called from other than the main thread. Robin Dunn suspects that it's a Carbon issue -- gestalt is calling Carbon, and doing so in the main thread, so you are then trying to call Carbon from more than one thread, which may be the cause of the problem. I've confirmed that if you call gestalt from the same thread as wxPython, there is no failure. A link to Robin Dunn's assessment: http://permalink.gmane.org/gmane.comp.python.wxpython/76590 As Carbon is deprecated anyway, I guess it's time for gestalt ( or platform.mac_ver ) to be re-written I've tested on OS-X 10.4.11, Python 2.5 and Python2.6 Here is Peter's summary and sample code: # Demonstration of application freeze on OSX. # Running "python osx_freeze.py" shows the symptom: # non-responsiveness after about 3 seconds. In theory # this will occur in any wxPython app which runs # the GUI event loop in a thread other than the one # in which the failing gestalt('sysu') call (see below) # is first executed. # Enabling any of these imports can trigger the problem # as each one imports the next one down in the list. # This will happen only with pkg_resources v0.6c10 or later # although it's not pkg_resources' fault. # import matplotlib.figure # import matplotlib.axes # import matplotlib.dates # import pytz # import pkg_resources # The next import alone doesn't lead to failure, # but the function call does. # This same code is executed by pkg_resources starting # with setuptools v0.6c10. # from platform import mac_ver; mac_ver() # The platform.mac_ver() call does the following, which # is what ultimately leads to the failure. Calls # to gestalt() with 'sysa' (for example) do not # trigger the problem, either because the problem is # related to the 'sysu' itself, or to the fact that # an exception is raised because the selector "sysu" # is no longer recognized. from gestalt import gestalt try: print gestalt('sysu') except Exception, ex: print 'gestalt call failed' if __name__ == '__main__': def gui(): import wx app = wx.App(False) frame = wx.Frame(None) wx.StaticText(frame, label='Goodbye, cruel world') frame.Show() app.MainLoop() import threading threading.Thread(target=gui).start() -- 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

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.

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.

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

Py2App Problems
by RSGames Support May 30, 2010

May 30, 2010

Hey, I am having some issues building my program with Py2App. My program makes use of the PyTTSX package (http://pypi.python.org/pypi/pyttsx/1.0). I know there are 2 arguments in Py2App that may need to be used (-i and -p). Since PyTTSX is a package, I first tried the -p parameter. Here is the output for that: running py2app *** using recipe: virtualenv *** *** using recipe: pygame *** *** filtering dependencies *** 581 total 60 filtered 5 orphaned 521 remaining Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 589, in _run self.run_normal() File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 659, in run_normal pkgdirs = self.collect_packagedirs() File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 637, in collect_packagedirs for pkg in self.packages File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/build_app.py", line 1045, in get_bootstrap bootstrap = imp_find_module(bootstrap)[1] File "build/bdist.macosx-10.3-fat/egg/modulegraph/util.py", line 13, in imp_find_module result = imp.find_module(name, path) ImportError: No module named pyttsx > /Users/MacAdmin/Desktop/RSG/zgp/src/build/bdist.macosx-10.3-fat/egg/modulegraph/util.py(13)imp_find_module() -> result = imp.find_module(name, path) (Pdb) I'm really unsure why it can't find pyttsx.

py2app query from a naif
by William R. Wing May 29, 2010

May 29, 2010

I'm trying to get py2app working so I can distribute a python application I've written for OS-X. I finally succeeded in getting py2app to run to completion with no errors, and it produces an output bundle with the right name and a cute icon. The recipe for success in getting that far was to override python 2.6's default behavior in OS X and force it to run in 32-bit mode using the "defaults write....." command in Apple's python man page. However, the output .app runs ONLY on the system on which it was created. Taking it to another OS-X box (also Intel architecture, also running the same level of OS X (10.6.3), and also running python2.6, but as it came from Apple (still 64-bit default), the .app won't run. The error message in the system log isn't crystal clear - at least to me. It is (this is a direct cut and paste) : 5/27/10 1:25:48 PM EthernetError[5822] A Python runtime could be located. You may need to install a framework build of Python, or edit the PyRuntimeLocations array in this application's Info.plist file where "EthernetError" is the name of the application bundle that I'm trying to launch. The error message does indeed say "A Python runtime could be located" (which I'd not think represented an error). When I look at the plist file I see: <key>PyRuntimeLocations</key> <array> <string>@executable_path/../Frameworks/Python.framework/Versions/2.6/Python</string> <string>/System/Library/Frameworks/Python.framework/Versions/2.6/Python</string> </array> which looks ok, at least to me (who doesn't know what to look for). I'm guessing that the error message should have been: "A Python runtime could NOT be located." Since the output bundle that py2app created was only 283kB (which seems small to me if it really contains a universal binary of the python interpreter), this would be sort of self-consistent. I know from reading other py2app exchanges on this list that I can't distribute Apple's binary, and eventually I'll have to replace it with one from python.org, but I'd like to get py2app running before I tackle that hurdle. What am I missing? Can anyone please help? Thanks, Bill

I thought I would play around with Python 3.x a bit and would like to ask if you have any recommendations if I should use the version available at python.org or the one available at activestate?
