Express Installation

Check for platform-specific instructions in the "In Depth" section, and set the environment variable CC if needed.

Note: On some platforms the CC environment variable must be set before building. Also note that the notation <CDAT_INSTALL_DIRECTORY> indicates the full path name of the directory into which CDAT is to be installed and the notation <CDAT_SRC_DIRECTORY> indicates the full path name of the directory where you uncompressed and un-tarred the CDAT source code.

Change the directory name to that where CDAT was un-tarred. At the prompt, type:

cd <CDAT_SRC_DIRECTORY>
./express_install  <CDAT_INSTALL_DIRECTORY> [options]

This will create 2 subdirectories
<CDAT_INSTALL_DIRECTORY>/4.3
and
<CDAT_INSTALL_DIRECTORY>/Externals

The first directory (4.3) will contain the actual python and python packages, to run CDAT you'll need to type
<CDAT_INSTALL_DIRECTORY>/4.3/bin/python
or
<CDAT_INSTALL_DIRECTORY>/4.3/bin/cdat
or to run the GUI:
<CDAT_INSTALL_DIRECTORY>/4.3/bin/vcdat

The second directory contains binaries and libraries needed by python, cdat or some cdat packages

the exectuables in <CDAT_INSTALL_DIRECTORY>/Externals/bin are linked back into <CDAT_INSTALL_DIRECTORY>/4.3/bin

So you really only need to put

<CDAT_INSTALL_DIRECTORY>/4.3/bin in your path

This new setup will allow to easily roll back to some older versions of cdat, and faster build of futur cdat versions
