Installing MySQLdb on Snow Leopard

Question

I'm having all sorts of trouble trying to instal MySQLdb (1.2.2) on snow leopard. I am running python 2.5.1 and MySQL 5.1 32bit.

Python and MySQL are running just fine.

I've also installed django 1.2.1, although I don't think thats all that important, but wanted to give an idea of the stack i'm trying to install. I am using python 2.5.x as my webhost only has that version as an option and I want to be as close to my production env as possible.

anyway...

After following many of the existing articles and tutorials which mention modifying _mysql.c and setup_posix.py etc, I am still running into trouble.

Here is my stack trace:

Does anyone have any ideas?

Answer 1

Rather late for the original question, but in case others - like me - are encountering the mystery of a missing stdarg.h, see below. I'm using MacOS X 10.7.3, MySQL 5.5.20, Python 2.7.2, MySQL-python-1.2.3.

My error message:

/Developer/SDKs/MacOSX10.6.sdk/usr/include/stdarg.h:4:25: error: stdarg.h: No such file or directory

The following blog post saved me: http://packetcloud.net/2009/09/22/installing-mysql-python-module-for-python-262-on-snow-leopard-using-xcode/

Summarizing the key bit:

Open up /Developer/SDKs/MacOSX10.6.sdk/usr/include/stdarg.h

Replace the line:

#include_next <stdarg.h>

With:

#include_next </Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/stdarg.h>

Then things work smoothly:

> sudo ARCHFLAGS='-arch x86_64' python setup.py build
> sudo ARCHFLAGS='-arch x86_64' python setup.py install

Answer 2

I usually install packages like this with MacPorts. It's package management software that handles all the downloading, configuring and installing for you. It's just like emerge on gentoo or apt-get on debian.

Make sure you have Xcode installed and install macports . Once you've got that installed, fire up the terminal and install mysql by typing:

$ sudo port install mysql5-server

Answer 3

I tried to solve this one for days myself and finally gave up.

I switched to postgres. It works pretty well with django on snow leopard, with one minor problem. For some reason auto_inc pk ids don't get assigned to some models. I solved the problem by randomly assigning an id from a large random range, and relying on the unique column designation to prevent collisions.

My production server is linux. Mysql and postgres install fine on it.

In fact, many on the #django irc channel recommended running a virtual linux instance on the mac to get around my mysql install problems on it.
