Setup a build environment

This guide shows the steps required for creating a complete deployment of the OpenCMT software for develpment and tests. 

Setup for Alma Linux 9

System setup

The basic requirement for the next recipe is working on a clean Virtual Machine with Alma Linux 9 operating system. These steps must be executed by root:

1. Be sure to have an updated version of the system, with the EPEL extension enabled: 

   sudo yum -y update
   sudo yum -y install epel-release yum-utils wget
   sudo yum-config-manager --set-enabled appstream crb extras plus
   

2. Install the metadata for the internal software repositories (GEANT4, and CMT): 

   sudo wget -O /etc/yum.repos.d/muotom.repo https://nexus.pd.infn.it/artifacts/repository/repo-files/muotom.repo

3. Install the tools and libraries required by the CMT software: 

   sudo yum install git gcc-c++ make cmake doxygen geant4-devel root-graf3d-eve root-geom-builder root-geom-painter root-geom-webviewer xorg-x11-xauth mesa-dri-drivers pcl-devel

4. Since the GEANT4 package does not contain the particle data sets, download the required files from central repository: 

   sudo geant4-dataset-download

Storage setup

The data for tests are available via NFS, add this row to the file /etc/fstab

cld-storage-01.pd.infn.it:/data/brickOpenstack/muon-steel/sdb /mnt/muotom-data nfs defaults 0 0

then create the directory and mount the endpoint

sudo mkdir -p /mnt/muotom-data
sudo chmod a+rx /mnt/muotom-data
sudo mount -a
