Software stack test build

and again and again and again...

Purpose

During my two year-long astronomical hiatus, one of the few activties I am regularly doing for SHiP is testing new stacks, in support to the Software Coordinator (Oliver).

For this, I am connecting to a Virtual Machine provided by CERN Openstack service, where the latest LTS Ubuntu version (currently 22.04) supported is mounted.

The machine is only accessible from lxplus, and it uses my ssh key for access.

Test-Building a new stack

Basically, create a path under the "fake" path /cvmfs/ship.cern.ch/. This naming is used to avoid confusion, when the package will be shipped to the CVMFS file system.

First, make sure to have git-lfs installed and active, due to the need of copying large files such as field maps:

git lfs install

Then, clone the cvmfs_release current master into the "release" with naming convention YY.MM (i.e. 24.09):

git clone --recurse-submodules https://github.com/ShipSoft/cvmfs_release 24.09

Please remember to update shipdist to the latest master (or the version Oliver will point me to)

Then, build FairShip and all related packages as usual:

aliBuild build FairShip --config-dir shipdist --defaults release --always-prefer-system
