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. Did find: ./_mysql.so: mach-o, but wrong architecture Everything *looks* ok: (eb)brianz@eb-brianz$ file _mysql.so _mysql.so: Mach-O 64-bit bundle x86_64 (eb)brianz@eb-brianz$ otool -L _mysql.so _mysql.so: /usr/local/mysql/lib/libmysqlclient_r.16.dylib (compatibility version 17.0.0, current version 17.0.0) /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 124.1.1) (eb)brianz@eb-brianz$ (eb)brianz@eb-brianz$ file /usr/local/mysql/lib/libmysqlclient_r.16.dylib /usr/local/mysql/lib/libmysqlclient_r.16.dylib: Mach-O 64-bit dynamically linked shared library x86_64 Huh? Something is not right here. It sucks that the OS X builds are so painful. I'm sort of at a loss at where to go next. Suggestions? Any help greatly appreciated!

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

Which version to install?
by Monte Milanuk Aug. 31, 2010

Aug. 31, 2010

Hello all, Now that I have things more or less back to the original for 10.6 on my Macbook, I'd like to install a slightly more up-to-date version for learning to develop with. Some of the things I'm interested in working with include wxpython/dabo, tkinter (with the new ttk themed widgets), pygame, etc. On the one hand I'd rather just jump straight to 3.1.x at this point, but since a lot of the above don't seem to be ported to 3.x yet... I guess that limits my choices? So... which route would you recommend, and why: MacPython from python.org, Activestate Python, or MacPorts python. Pros and cons would be appreciated. Thanks, Monte

python 2.6.6 installer
by Ronald Oussoren Aug. 31, 2010

Aug. 31, 2010

Hi, The MacOSX installer for python 2.6.6 can now be downloaded at <http://www.python.org/download/releases/2.6.6/>. 2.6.6 has been out for a week, but sadly enough I had completely missed the release-manager's message about this on the python-committers list. Thanks to Ned for warning me about the release. Ronald

'Cleaning house' - getting back to just Apple's Python
by Monte Milanuk Aug. 28, 2010

Aug. 28, 2010

Hello all, I have an older Intel Macbook (circa early 2007) that I have upgraded the hardware and software a bit on over the last few months. Currently it is running Snow Leopard 10.6.4, with an install of Python 2.6.5. Over the course of time, between various upgrades, removing this, reinstalling that, etc. etc. I think I've made somewhat of a mess of my Python install and I'd like to clean house and get back to just the version that shipped with 10.6.x. No extras or add-ons. Once I get that kind of under control, then maybe see about upgrading/ or having multiple versions installed, etc. 1st question... What is the default version of Python that shipped with 10.6 Snow Leopard? I have a Python 2.6.5 install in my Applications directory, and I can't recall if I put that there or if that came with the new OS (I happened to do the OS upgrade around that time frame...). When I look under /Library/Frameworks/Python.framework/Versions I see the following: macbook:~ monte$ ls -al /Library/Frameworks/Python.framework/Versions/ total 8 drwxr-xr-x 5 root admin 170 Mar 23 17:46 . drwxr-xr-x 6 root admin 204 Mar 23 17:17 .. drwxrwxr-x 11 root admin 374 May 12 22:04 2.6 drwxrwxr-x 9 root admin 306 Aug 24 2009 3.1 lrwxr-xr-x 1 root admin 3 May 7 16:31 Current -> 2.6 macbook:~ monte$ If I remove the Python 2.6.5 install from the Applications directory, is that going to affect things here, or is this a separate (OEM) install? Sometime in the recent past I remember installing, and then uninstalling Python 3.x... so if I remove the 3.1 directory sub-tree, will that clean out that bit so I can start over fresh? Sorry 'bout the confusion. Monte

How do you tell the system which version to use ?
by Dan White Aug. 22, 2010

Aug. 22, 2010

I find that I have at least 3 versions of Python on my system. 2 under /System/Library/Frameworks/Python.framework/Versions (2.3 and 2.5) and one under /Library/Frameworks/Python.framework/Versions (2.7) Going from Terminal, I get 2.7 Running a script in Scribus, I get 2.3 I found info that says the /System/Library/Frameworks are part of the OS installation and that it should not be messed with. OK. But how do I get everything to use 2.7 ? Thanks.

A script for Scribus that won't run on my Mac
by Dan White Aug. 22, 2010

Aug. 22, 2010

I am a python n00b, and I cannot figure this out. I got a script from forum that is supposed to "build" a set of calendar pages in Scribus. It won't run on my Mac (Intel iMac, MacOS 10.5.8, Python 2.7, Scribus 1.3.8) Here is an extract containing the offending code: --------------------------------------------- def drawRulesGrid(pageSide): """Draws rules on the page""" lineSpace = (LINE_LAST_Y - LINE_FIRST_Y) / 30 if pageSide == 'right': StartLines = (R_LINE_X + (C * LINE_X_OFFSET) for C in range(COLUMNS)) BigLines = [0, 10, 20, 25, 30] elif pageSide == 'left': StartLines = (L_LINE_X + (C * LINE_X_OFFSET) for C in range(COLUMNS)) BigLines = [0, 10, 20, 30] for j in StartLines: StartLineX, StartLineY = j, LINE_FIRST_Y for i in range(31): Line = createLine(StartLineX, StartLineY, StartLineX+LINE_LENGHT, StartLineY) if i in BigLines: setLineWidth(BIG_LINE_WIDTH, Line) else: setLineWidth(THIN_LINE_WIDTH, Line) StartLineY += lineSpace --------------------------------------------- And the error: --------------------------------------------- Traceback (most recent call last): File "", line 8, in ? File "SamAgenda.py", line 221 StartLines = (R_LINE_X + (C * LINE_X_OFFSET) for C in range(COLUMNS)) ^ SyntaxError: invalid syntax --------------------------------------------- In case the spacing gets messed up, the caret is pointing at the "r" in "for" The author claims this runs on python 2.6.5, Scribus 1.3.3.13svn, Ubuntu 10.04. Any clues for this clueless one ? Thanks.
