Notes on getting pyWrapper to link to mx

The installation guide is here:

for OS X (10.3.9)

While its not very clear from the initial installation notes on the pyWrapper site I think you can just do part A and it will attempt to install all the necessary components. If not do the following from B:

  • Steps 1 and 2 went off without a hitch after I installed the latest version of Python (2.4).
  • Step 3 (lxml)

There are two dependencies, libxml2 and libxslt. Using MacPorts to install these is probably a good idea. Install MacPorts following this. Now:

sudo port selfupdate
sudo port install libxml2
sudo port install libxslt
sudo port install py-setuptools

XCode for 10.3.9 has old build tools, so if you encounter any build-related errors during this process, you may be able to get things working by using 'port' to install newer versions of the build tool in question (e.g. 'sudo port install autoconf' or 'sudo port install gperf').

After doing all this (do update both autoconf and gperf on a fresh install of 10.3.9) you can install lxml with this:

sudo easy_install lxml

This fixes the paths etc. too.

OR, if you don't want to use 'sudo easy_install lxml' you can:

Now, download and unpack lxml, and run

python build

or 'make' in that directory. You will need to make sure the contents of the 'lxml-X.X.X/src' directory is in your PYTHONPATH, either by moving them or adding the directory to the path (I'm not a python person, so I don't know what the proper way to manage Python libraries is).

Connection tab

Use the settings in the database.yml file of mx.

Sweeet ... more soon.
