Software Installation

ICD 13—Standard Controller ICD-13/05 41 of 56

17.0 Software Installation

The following sections describe the installation of the software components of the Stan-

dard Controller, comprising both the commercial and community packages which will

be used in implementing a Gemini work package IOC. These sections are not meant as a

replacement for the existing installation instructions which come with the software

package, but contain enhancements and modifications to those instructions where

appropriate for Gemini systems.

Installation of software should be done by the system administrator. At a minimum, the

accounts “epics”, and “p3” need to be created, and a suitable amount of disk space

assigned to their home directories. The “epics” account needs at least 250 Mbytes, and

the CapFast “p3” account needs at least 35 Mbytes of free space. It is also useful for a

symbolic link to be made from the EPICS home account to /opt/local/epics. This allows

all Gemini software to access EPICS at the same location.

The location of the software may vary from sites, depending upon the available

resources and for historical reasons. The installation descriptions that follow are only a

guide and an example of where to install the software.

17.1 Accounts and Directories

The following should be performed by the system administrator as ‘root’:

1. Create an account for EPICS called “epics”. Allow at least 250 Mbytes for the home

directory.

2. Create an account for Capfast called “p3”. Allow at least 35 Mbytes for the home

directory.

3. Create a symbolic link from the EPICS home directory to /opt/local/epics.

ln -s ~epics /opt/local/epics

The following system administration should be done as user “epics”:

1. Install VxWorks in the EPICS home directory. See “VxWorks” on page 42.

2. Create a symbolic link between the VxWorks release directory and “vxworks”.

ln -s ~epics/vxworks5.2 vxworks

Install EPICS in the EPICS home directory. See “EPICS” on page 47.

4. Create a symbolic link between the EPICS release directory and “epics”.

cd ~epics

ln -s epics3.12.2Gem4 epics

The following system administration should be done as user “p3”:

1. Install CapFast in the “p3” home directory. See “CapFast” on page 51.
