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.
