Delta Tau Power PMAC EPICS Device Support Manual

8 February 2013

5 Installation Under Linux

This section covers installation of the device support code for the Power PMAC on a

Linux operating system.

5.1 libssh2 Installation

The lower level driver class provided by the EPICS module requires that an external

library be installed on the system to handle SSH encryption and connections. The

library libssh2 (http://www.libssh2.org) should be downloaded and installed. The

version that the driver has been built against is 2-1.4.3.

Either download using the link on the libssh2 website, or from a command line

download using wget:

wget http://www.libssh2.org/download/libssh2-1.4.3.tar.gz

Unpack the archive to a suitable location, configure, build and install.

gunzip libssh2-1.4.3.tar.gz

tar -xvf libssh2-1.4.3.tar

cd libssh2-1.4.3

./configure

make

make install

The libraries are by default installed in /usr/local/lib. Note that installation in that

location requires root access.

On the Debian 6 operating system it was first necessary to install some extra

packages:

apt-get install build-essential

apt-get install openssl

apt-get install li/jointfilesconvert/305696/bgcrypt-dev

Note that a libssh2 Debian package already exists but the current package version is

not compatible with this module.

5.2 EPICS Base and Modules

The Power PMAC module has been developed against EPICS base version 3.14.12.1,

asynDriver version 4.17 and motor version 6.7.1. These modules must be installed

before attempting to compile the Power PMAC module.

EPICS base can be downloaded from http://www.aps.anl.gov/epics. The module has

also been tested against the Debian EPICS package available from NSLS II

(http://epics.nsls2.bnl.gov/debian) which can be installed using the Debian package

management system.
