hcana with externally built evio libraries
============================================
As of PODD version 1.6, EVIO is built as an external library from the official JLAB
DAQ group source code. As of this writing, the official release is version 4.4.5.
In order to compile hcana with PODD version 1.6, one must download, install, and define
appropriate environment variables for the evio libraries.
Downloading
-----------
On your local system, retrieve and unpack the EVIO source distribution:
$ wget --no-check-certificate https://coda.jlab.org/drupal/system/files/coda/evio/evio-4.4/evio-4.4.5.tgz
$ tar -xvzf evio-4.4.5.tgz
$ cd evio-4.4.5
This will unpack the EVIO source code in a directory called evio-4.4.5, and take you
into that new directory.
Compiling
---------
You can now compile the EVIO libraries with:
$ scons
$ scons install --prefix=.
This will install the libaries in a subdirectory of the current source directory according to the operating system that you are using.
Environment
-----------
The final step is to define the environment variables necessary to tell hcana where your EVIO libraries are installed. I include here excerpts from a my .cshrc file on the JLab systems (where the SHELL is tcsh), and also from my .bash_profile file on a Mac OS X system (where the SHELL is bash). This should give you enough of a guide to be able to modify your environment variable definition appropriately.
