Ganga Installation and Download

News

Mon, 14 May 2012 09:37:50 +0000: Latest public release is 5.8.1-hotfix1

Users with AFS access (e.g. lxplus):

LHCb users

GangaEnv
ganga

All LHCb plugins will be automatically enabled.

Atlas users

source /afs/cern.ch/sw/ganga/install/etc/setup-atlas.sh
ganga

All Atlas plugins will be automatically loaded.

Other users

On lxplus no installation is needed, you may just start Ganga directly:
/afs/cern.ch/sw/ganga/install/5.8.1-hotfix1/bin/ganga

For convinience you may set your PATH or make an alias.
You will get the default set of plugins. You may enable new plugins in the ~/.gangarc config file.

Local installations (e.g. laptops):

First download the Ganga installation script: ganga-install

A given version of Ganga for slc3_gcc32 can then be downloaded and installed using:
python ganga-install options VERSION
where you need python 2.2 or greater.

You can optionally request installation of additional Ganga packages, and the external packages on which they depend. The following are strongly recommended:

For Atlas: --extern=GangaAtlas,GangaNG,GangaCronus,GangaGUI,GangaPlotter
For LHCb: --extern=GangaLHCb,GangaGUI,GangaPlotter
GUI only: --extern=GangaGUI,GangaPlotter

For information on additional options, use: python ganga-install --help

To enable the ATLAS runtime plugins, use:

bash: export GANGA_CONFIG_PATH=GangaAtlas/Atlas.ini
tcsh: setenv GANGA_CONFIG_PATH GangaAtlas/Atlas.ini

In addition, to enable use of the Cronus and NorduGrid plugins, you should change RUNTIME_PATH in your GangaAtlas/Atlas.ini file to:

RUNTIME_PATH = GangaAtlas:GangaCronus:GangaNG

This is likely to become the default in a future Ganga release.

To enable the LHCb runtime plugins, use:

bash: export GANGA_CONFIG_PATH=GangaLHCb/LHCb.ini
tcsh: setenv GANGA_CONFIG_PATH GangaLHCb/LHCb.ini

Troubleshooting

Failed to fetch http file: check your network connection and try if you can do wget http://cern.ch/ganga/index.html. If the network is OK then check if you do not have the web server proxy.
Web server proxy may occasionally cause problems to download ganga via http. You can fix this problem by setting the environment variable.
bash: export http_proxy=http://ip.or.name.of.the.proxy.server
csh: setenv http_proxy http://ip.or.name.of.the.proxy.server
