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!

May 21, 2010

hi, i have to work with mac OS 9.2 for legacy reasons...is there a compiled version of python for this os ? i need to get input about variable values from the user and then print out some text files that make use of this input. a gui would be nice, but keyboard based input would be ok too... thanks much, suresh ps. if there isn't a version of python that will work, perhaps you could suggest some other scripting language for 0S 9.2 ?

Problems with py2app and qt
by aditya bhargava April 22, 2010

April 22, 2010

Hi python users, I'm getting some strange results running py2app on my machine. It works fine with most scripts, but any time I use it with a script that uses PyQt, the built application immediately quits and gives me an "unexpectedly quit" message. It's not the code, because I tried py2app with a couple of the example scripts that come with PyQt and got the same result. Any thoughts? I'm on mac OS X 10.4 running Python 2.5. My copy of py2app is very recent, I just got the latest one yesterday. Thanks for your help! Aditya

It's an issue with macholib and/or py2app, in that they don't seem to be able to handle four-way universal builds. So PySide may not be the answer at all. -- Kevin Walzer Code by Kevin http://www.codebykevin.com

Python Complier
by Chuck Hauge Feb. 14, 2010

Feb. 14, 2010

Hello ~ I'm quite new to Python, and wanted to compile an app, GNS3 (http://www.gns3.net/download) and have everything running from the Python code. I wanted to make it an executable .app so that I can distribute and make it available to the GNS3 community (this would put the Mac on par with Windows and Linux in regards to high-end Cisco networking emulation). I had found py2app and tried to compile it with that, but bumped into what appears to be a couple issues. I could not find documentation on how to overcome the issues, and am not certain if it is that py2app can not compile the Python, or if I'm missing something. I contact Bob Ippolito who informed me that he no longer supports py2app. If there is a compiler better than py2app I'd greatly appreciate the input, or if someone knows how to get around the issues, assuming there is a way. Here are the issues that came up during the compile: File "/Library/Python/2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/util.py", line 101, in copy_file zf, zp = path_to_zip(source) File "/Library/Python/2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/util.py", line 133, in path_to_zip raise DistutilsFileError(path) DistutilsFileError: /private/tmp/GNS3-0.7RC1-src > /Library/Python/2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/util.py(133)path_to_zip() -> raise DistutilsFileError(path) (Pdb) q Traceback (most recent call last): File "/usr/local/bin/py2applet", line 8, in <module> load_entry_point('py2app==0.4.3', 'console_scripts', 'py2applet')() File "/Library/Python/2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/script_py2applet.py", line 134, in main build(args, scripts, data_files, options) File "/Library/Python/2.6/site-packages/py2app-0.4.3-py2.6.egg/py2app/script_py2applet.py", line 187, in build target.appdir, AttributeError: 'Target' object has no attribute 'appdir' Thanks, Chaz Hauge

problem running py2app
by Attila Tajti Feb. 3, 2010

Hello, As my first Mac OS X project I am trying to build a sample plugin with py2app. I am following this tutorial: http://eaganj.free.fr/weblog/?post/2009/07/14/Demystifying-Mail.app-Plugins… I do not know what am I doing wrong, but I cannot seem to be able to create my plugin in the first place. python setup.py py2app -A works, but creating a standalong plugin fails. Do you know what is wrong?

Interesting article on 64-bit py2app

Looks like someone has made some progress with a 64-bit-supporting version of py2app http://www.hardcoded.net/articles/building-64-bit-pyobjc-applications-with-… And here are his source trees: http://hg.hardcoded.net/py2app/ http://hg.hardcoded.net/macholib/ (I have not tested these in any way, so use at your own risk...) -- Kevin Walzer Code by Kevin http://www.codebykevin.com

pyopencl
by Markus Mohr Jan. 27, 2010

Jan. 27, 2010

Hi, I would like to try out OpenCL on 10.6. When I searched for python and opencl I thought I'd just found several mirrors of the same project but it looks like there are at least 4(!) pyopencls. That would be: http://mathema.tician.de/software/pyopencl (has entry on python.org) http://sourceforge.net/projects/pyopencl/ http://python-opencl.next-touch.com/ (has entry on python.org) http://gitorious.org/python-opencl Has someone used any of these? A recomendation perhaps? Thanks, Markus
