The Elixir system consists of two main software packages: Ohana (main developer Eugene Magnier) and Flips (main developer Jean-Charles Cuillandre). The Elixir system combines these two packages, along with other external software products, into a complete system providing many utilities and functions for image processing at CFHT and elsewhere. This document describes how to install the Ohana portion of the Elixir system. Ohana may be installed from CVS or from a distributed tar ball. Within the Elixir development community, the Ohana source tree may be checked out of the Elixir CVS tree. Ohana is also distributed as a tar ball to users outside of the Elixir development community.

1) Installing Ohana from source tar ball:

un-gzip and untar:

> gunzip -c ohana.tgz | tar xvf -

enter the ohana top-level directory:

> cd ohana

construct the input Configure file [1]:

> configure

this step will note the binary installation path. This should be added to your PATH. Next, compile the software:

> make

install the software

> make install

2) Installing Ohana from CVS (Developer's version):

check out the ohana source tree:

> setenv CVSROOT poma:/data/elixir2/srcdir/cvs

> cvs co ohana

enter the ohana top-level directory:

> cd ohana

construct the input Configure file [1]:

> configure

this step will note the binary installation path. This should be added to your PATH. Next, compile the software:

> make

install the software

> make install

Notes

[1] Ohana is configured for multiple architecture development, which is convenient for end users as well. The libraries, include files, and programs, are all installed in directories with the architecture type appended: bin/linux, bin/sol, lib/linux, etc. To take advantage of this multiple architecture organization when compiling, end users should arrange for the environment variable ARCH to be set based on the machine architecture, and for the PATH to depend on ARCH, rather than setting it to a fixed quantity.
