LHCb Nightly builds

Status of nightlies

The current status of the LHCb nightly builds is available at http://cern.ch/lhcb-nightlies/cgi-bin/nightlies.py. See also the status of the LCG nightlies (unmaintained version) .

RSS feeds reporting about error/warning details for slots, projects or specific platforms are available on the summary webpage:

• predefined RSS feeds - "Display Criteria" -> "display RSS feeds"
• user defined RSS feeds - use "Custom RSS feed configuration" in the top of the summary webpage

If you prefer to get e-mail messages contaning these information, the rss2email open-source tool is recommended (can be used on lxplus).

Running from the nightlies

The following instructions are for DaVinci, but they apply to any other project; instructions for Gauss are here. The first thing is to decide which slot. Usually one slot builds DaVinci on the latest LHCb, or the LHCb release candidate, and the other uses the head of Gaudi. Which one to pick is up to what you want to do. See http://lhcb-nightlies.web.cern.ch/lhcb-nightlies/cgi-bin/nightlies.py for the definitions. Then decide on the day. Make sure that the version you picked actually compiles. Now you have a slot, say lhcb-head and a day, say last night.

First do

SetupProject DaVinci HEAD --build-env --nightly lhcb-head [ day ]

where day is optional. The default is today, or pick up a day like Mon, Tue... This builds you a directory ~/cmtuser/DaVinci_HEAD/. In there getpack what you need

getpack Phys/DaVinci head

and the needed packages. Then do

SetupProject DaVinci HEAD --nightly lhcb-head [ day ]

i.e. the same as above without the --build-env. Now $DAVINCIROOT should point to your getpacked DaVinci and you can run.

You can also run from ganga (not on the grid, only at CERN) using the setupProjectOptions field to pass the right options to SetupProject.

See also the SetupProject wiki.
