How to install MySQLdb on Leopard with MAMP

Like many others, I struggled for a good hour to install the recommended MySQL module for Python, which is MySQLdb. So I’m sharing here the solution I found ;-)

The latest MAMP (1.7.1) uses MySQL 5.0.41, and MacOS X Leopard (10.5) uses Python 2.5.1 . As I couldn’t find a prebuilt MySQLdb binary for those versions, well, I had to compile my own.

So let’s go for it :

$ tar zxvf mysql-5.0.41.tar.gz $ cd mysql-5.0.41 $ ./configure && make $ sudo make install $ cd ..

(now MySQL is installed in /usr/local/)

$ tar zxvf MySQLdb... $ cd MySQLdb...

  • In the MySQLdb folder, edit the file _mysql.c

    • Delete the following lines :

      #ifndef uint

    #define uint unsigned int

    • Replace 2 occurences of “uint” by “unsigned int”
  • Then edit the site.cfg file, and set the mysql_config variable to “/usr/local/bin/mysql_config”

(Still in the MySQLdb folder)

$ python clean $ python build $ sudo python install $ sudo rm /tmp/mysql.sock $ sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock

And that’s it! You should now be able to “import MySQLdb” in python. Good luck!
