Error installing MySQL-python on MAC Snow Leopard, OS 10.6

Question

I am trying to install the MySQL-python on MAC OS 10.6 (Snow leopard, 64 bit). I followed the steps: 1. Installed MySQL for Mac OS X ver. 10.6 (x86, 64-bit), DMG Archive. 2. Downloaded MySQL-python-1.2.3c1.tar.gz and unzipped it 3. CD to MySQL-python-1.2.3c1 and built it as: ARCHFLAGS="-arch x86_64" python setup.py build (see output bnelow) 4. Installed it as: ARCHFLAGS="-arch x86_64" python setup.py install 5. But when I tried to import MySQLdb to python, I am getting error message

import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "build/bdist.macosx-10.3-x86_64/egg/MySQLdb/__init__.py", line 19, in <module>

  File "build/bdist.macosx-10.3-x86_64/egg/_mysql.py", line 6, in __bootstrap__
ImportError: dlopen(/Users/krokodil/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.3-x86_64.egg-tmp/_mysql.so, 2): no suitable image found.  Did find:
 /Users/krokodil/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.3-x86_64.egg-tmp/_mysql.so: mach-o, but wrong architecture

This "macosx-10.3-x86_64" is bothering me - it seems that somehow the build/install thought that I am still on Mac OS 10.3. Please also see Build and Install capture below. It also using /Developer/SDKs/MacOSX10.4u.sdk compiler, not /Developer/SDKs/MacOSX10.6.sdk

I am using fresh install of Python 2.6.4. I saw people having probles. Anyone found a good solution?

Thank you Vlad

Answer 1

The python 2.6.4 you are using is 32-bit only (definitely true if you downloaded the OS X installer from python.org). You can't override the architecture for extension modules; they have to be compatible with the base python. The 10.3 shows up because the python you are using was built with a deployment target of 10.3 as it is designed to run on multiple versions of OS X. If you want to use a 64-bit version of MySQL, you'll need to use a 64-bit version of python, like the Apple-suppled python 2.6.1.
