Installation Guidelines: Mac - Developer - Manual

Install Apple developer tools

You will need ​Apple's Xcode Developer Tools (version 4.1 or later for Lion, 3.2 or later for Snow Leopard, or 3.1 or later for Leopard), found at the Apple Developer Connection site, on your Mac OS X installation CDs/DVD, or in the Mac App Store. Using the latest available version that will run on your OS is highly recommended. Ensure that the optional components for command line development are installed ("UNIX Development", plus "System Tools" in newer versions, or "Command Line Support" in older ones).

Caution: The Xcode download is over 3GB.

Install GIS tools

For some GIS features of Eden (e.g. if you would rather use PostgreSQL with PostGIS instead of MySQL) install the ​GDAL framework

Install Python

​Mac installer for Python

Install Python packages

You can use ​easy_install or ​pip for these installations.

STATIC_DEPS=true sudo easy_install lxml
sudo easy_install shapely
sudo easy_install reportlab
sudo easy_install xlwt
sudo easy_install pyserial
sudo easy_install tweepy

If you want to use PostgreSQL - PostGIS (for which you will need GDAL, above):

• Install the one clickInstaller sponsored by EnterpriseDB PostgreSQL and select also installation of PostGIS.
• Following ​these instructions install the Python database driver:

  sudo easy_install pip
  PATH=$PATH:/Library/PostgreSQL/8.4/bin/ sudo pip install psycopg2
  defaults write com.apple.versioner.python Prefer-32-Bit -bool yes
  

  (Without the last Web2py will not be able to find the PostgreSQL driver.)

Trouble?

• lxml can give trouble on OS X. Try:
  • STATIC_DEPS=true sudo easy_install lxml (adapted from ​this blog post)
  • remove other libxml2 versions, such as may have been installed by fink or MacPorts - ONLY works in unmodified Python setup. In case you have modified your Python you must link some how the python directory with /frameworks/python otherwise lxml will not being found(not tested)
