Running Gaussino
Please note that Gaussino is an experiment-independent package. If you are looking for a concrete experiment implementation, here is the list:
Gauss-on-Gaussino (LHCb Experiment)
Running from the nighlties
Currently it is only possible to build Gaussino with the help of nightly builds.
You can check the nighlty build status by visiting https://lhcb-nightlies.web.cern.ch/nightly/. The nightly slot currently available for Gaussino is lhcb-gaussino
. You can either install the latest build or one from the past in case the current one is failed.
Configuring the environment
Make sure you’re using LbEnv on lxplus or similar. You can run this to be sure:
source /cvmfs/lhcb.cern.ch/lib/LbEnv
Configure the platform
lb-set-platform x86_64_v2-centos7-gcc11-opt
Note
Use x86_64_v2-centos7-gcc10+dd4hep-opt if you want work with Detector/DD4hep.
Building from source
Note
This is the recommended way for now.
Fetch the nightlies locally
lbn-install --verbose --platforms=x86_64_v2-centos7-gcc11-opt --projects=Gaudi,Geant4,DBASE,Detector,LHCb,Run2Support lhcb-gaussino Today export CMAKE_PREFIX_PATH=$PWD:${CMAKE_PREFIX_PATH}
Note
Use x86_64_v2-centos7-gcc11+dd4hep-opt if you want work with Detector/DD4hep.
OR (less recommended) add the nightlies path to
CMAKE_PREFIX_PATH
directly from the destinationexport CMAKE_PREFIX_PATH=/cvmfs/lhcbdev.cern.ch/nightlies/lhcb-gaussino/latest:${CMAKE_PREFIX_PATH}
Clone the repository.
git clone ssh://git@gitlab.cern.ch:7999/Gaussino/Gaussino.git cd Gaussino
Note
Don’t forget to merge all pending merge requests with a label
`lhcb-gaussino`

This might be useful if you want a local copy of the projects in the nighlt slot or if you’re looking for a nightly slot that is no longer present in /cvmfs/lhcbdev.cern.ch/nightlies/lhcb-gaussino
ll /cvmfs/lhcbdev.cern.ch/nightlies/lhcb-gaussino

```Today```` nighlty slot will be used in further steps.
Create a base directory for your nighlties.
mkdir gaussino_base
Install the nightlies in your base directory.
lbn-install --verbose --projects Gaussino --platforms x86_64-centos7-gcc9-opt --dest gaussino_base/lhcb-gaussino/Today lhcb-gaussino Today
Use the nightlies in your base directory to work on a satellite project.
