* ganga 5.1.0 is released and announced to LHCb, since lhcb-proxy-inxx scripts have been adapted in $LHCBSCRIPTS on AFS at CERN. Therefore ganga 5.1.0 is usable at CERN (first two points ;0)
* DIRAC distribution: Ricardo reports that having run dirac_install on their LHCb SW installation at Barcelona, he managed to run ganga... with some caveats:
1. the (in)famous voses file is missing. Action: it will be created in $DIRACROOT/etc/vomses by dirac_install. The environment variable DIRACVOMSES will then be created by SetupProject and that's it (Ricardo)
2. error messages when starting ganga: due to the fact that Ricardo's installation is not complete, and some default configuration elements should be replaced by the local ones
Long discussion on how to control the DIRAC version...
* At CERN (or on globally managed installation), better fix the version of DIRAC in the local configuration file
* On private installation, not needed, as users will only install DIRAC after it was advertised to do so
ganga should add a configuration parameter DiracVersion (supersedes the version currently extracted from DiracTopDir which then should be deprecated). In absence SetupProject should be called without parameter.
In order to be able to install ganga and DIRAC with install_project, one should define a CMT project gangaLHCb that creates the relation between the current ganga and the preferred DIRAC version, whenever a new version of DIRAC should be installed and used as default.
Installing DIRAC: Joel will provide instructions on how to install DIRAC in the standard LHCb SW release area. Note that at least one project of LHCb should have been installed, but this is the usual use case for most users. Further instructions will be given for installing only DIRAC and the necessary LHCb scripts (use case for people submitting scripts).
