Linear Collider activities in Glasgow

Software

• VO membership via ilc link at http://grid.desy.de/certs/vos.html
• ilcsoft local installation temporarily at /data/atlas01/ILC/ilcsoft

Installation of ILC software at Glasgow

Getting the latest version

Two choices for downloading the software is through svn or via a tarball. For the first attempt I opted for the latter. To do this I

went to:

https://svnsrv.desy.de/viewvc/ilctools/ilcinstall/tags/

and downloaded the tar file accessible here:

https://svnsrv.desy.de/viewvc/ilctools/ilcinstall/tags/?view=tar

into the temporary directory(soon to be replaced by an afs area)

/data/atlas01/ILC

I then untarred the file:

tar xvfz ilctools-tags.tar.gz

I then went into the directory:

/data/atlas01/ILC/tags

and removed all other tags except for the latest v01-14.

(Using svn to check out this tag would have been a more sensible way - will do next time!)

Preparing for build

First we must prepare four packages that don't come automatically with the ilcsoft installation.

They are MySQL, Java, xerces-c and cernlib. MySQL was installed by sysadmin (Andy) as root

privileges are necessary. Java is already installed on our network. So it was necessary to install

xerces-c and Cernlib. I installed them in the:

/data/atlas01/ILC

directory. For xerces-c I did the following:

mkdir xerces-c

And in this directory I:

wget http://apache.mirror.rbftpnetworks.com//xerces/c/3/binaries/xerces-c-3.1.1-x86_64-linux-gcc-3.4.tar.gz

for 64 bit. And untarred.

For Cernlib I realised that the installation here (/usr/lib64/cernlib) did not have the inlcude

directories needed so I also went to /data/atlas01/ILC and created directory 2006b

and in this directory I downloaded:

wget http://wwwasd.web.cern.ch/wwwasd/cernlib/download/2006b_x86_64-slc5-gcc41-opt/tar/cernlib.tar.gz_

and

wget http://wwwasd.web.cern.ch/wwwasd/cernlib/download/2006b_x86_64-slc5-gcc41-opt/tar/include.tar.gz_

and untarred them.

Preparing release version file

First of all I created a directory where the ilcsoft software packages will actually be installed

into. This is called: /data/atlas01/ILC/ilcsoft

It is now necessary to point to the above installations (MySQL etc.) in the release file that comes with

the ilcsoft installer. To do this I went to file:

/data/atlas01/ILC/v01-14/releases/v01-14/release-versions.py

But I first tell this file where the ilcsoft install directory is by setting:

ilcsoft_install_prefix = "/data/atlas01/ILC/ilcsoft/"

I then added:

MySQL_path = "/usr/"

Java_path = "/usr/java/latest/"

CERNLIB_path = "/data/atlas01/ILC/2006b/"

XERCESC_ROOT_DIR = "/data/atlas01/ILC/xerces-c/xerces-c-3.1.1-x86_64-linux-gcc-3.4/"

to this file

Starting a full build for all packakges

The file at the centre of this build is called 'release-scratch.cfg' which can be found in

the same directory as the release-versions.py: /data/atlas01/ILC/v01-14/releases/v01-14/

This file has the list and order in which all packages must be installed. First of all it is

necessary to point to the release-version.py file from within this file:

path_where_this_file_lives = "/data/atlas01/ILC/tags/v01-14/releases/v01-14"

Then do:

./ilcsoft-install -p releases/v01-14/release-scratch.cfg –p (to check all is ok)

./ilcsoft-install -p releases/v01-14/release-scratch.cfg –I (to install)
