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?

py2app 64 bit or 32 bit
by BjornJohansson Oct. 31, 2010

Oct. 31, 2010

Hi, I have a couple of questions about py2app. I would like to make a mac executable from a wxPython app that I have written. I have ubuntu 10.04 64-bit version with py2app installed. Can I use this setup to create generally usable apps or do I have to use a 32 bit version of Ubuntu? I am new at this, but I have managed to create a win executables using py2exe.

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?

Hi, I understood that py2app can only produce mac .apps when run on macosx and not linux. Is this correct? /bjorn -- View this message in context: http://old.nabble.com/py2app-on-linux-tp29969167p29969167.html Sent from the Python - pythonmac-sig mailing list archive at Nabble.com.

pyobjc with appscript
by Adam Morris Oct. 25, 2010

Oct. 25, 2010

Dear Pythonmac-sig, I have a python script that gives Keynote some added features useful to teachers. It lets students interact with whatever is being projected right at their desk. It's written in python using appscript but at the moment runs entirely from the command line. I'm looking at giving it a GUI. I'm considering using the AppleScriptObjC bridge, but that means converting all my convenience classes from python/appscript into pure AppleScript (boo). The upside though is that I could get started on that right away. I'd really rather use PyObjC but would need a helping hand getting started on making a deployable Snow Leopard-only app, and getting it so that appscript is included. How do I do that without requiring the user to have appscript in its python path? This isn't the first time I've tried figuring this out and don't understand how this works. Can someone point me in the right direction? I'd also be happy to write about my progress making the app so that it might be useful for the future. -Adam

how to add custom dylib for module?
by chris.ord Oct. 25, 2010

Oct. 25, 2010

I am trying to enable python-drmaa control of my gridengine cluster but I am coming up against problems caused by my ignorance. I have an nfs share where the full suite of application & software lives. e.g nfs_share/grid/darwin/lib/drmaa.dyld & nfs_share/grid/darwin/bin/sub.app I have a working path in that I can run sub.app and it works. The python-drmaa module claims it has installed ok. It hasn't as it can't find the drmaa.dyld I have attempted to set DYLD_LIBRARY_PATH & DRMAA_LIBRARY_PATH however these do not seem to hold very well in Mac x My question is how do I add a custom path for any dyld that a python module requires? I'm an Admin not a programmer so I have a 'hazy' notion at best of how a module relates to the underlying C or dyld objects. I have successfully dealt with the linux version of this problem but the python on mac situation seems to be more fragmented. Either specific help or (probably better) a pointer to some documents about how this element of python works as I would love to roll my own deployments from a central point and my lack of knowledge in this area is holding me up. Versions Mac 10.6 & 10.5, python 2.6 TIA Chris -- Chris Ord IT Manager 4-14 Dickson Ave. Artarmon NSW 2064 mobile: 0401 836 500
