Building CDAT on Mac

• Requirements
  • You will need X11 to run CDAT. If you don't have it, install it from your Mac OS X Install Disc

• Follow these instructions to install vistrails development environment

• Download cdat form the source code repository

  svn checkout http://www-pcmdi.llnl.gov/svn/repository/cdat/trunk cdat 

• Download this patch (building NetCDF without Fortran support) or if you have fortran compiler installed, download this other patch and uncompress to the cdat folder.

• Perform the following commands:

 $ unset PYTHONPATH
 $ cd cdat/exsrc
 $ sudo ./install_script /Library/Frameworks/Python.framework/Versions/2.4
 
 $ sudo python install.py /Library/Frameworks/Python.framework/Versions/2.4

• Before running vistrails, reset PYTHONPATH variable:

 $ export PYTHONPATH=<path/to/vtk_build>/Wrapping/Python:<path/to/vtk_build>/bin:.

When running vistrails with cdat package, you'll have to run vistrails from an X11 terminal.
