Tutorial

Introduction

This tutorial should give an introduction to trigger algorithm developers how to set up the environment needed, make changed, compile, build and run the system

Overview

Setting up the environment under dunedaq-v2.2.0

Detailed documentation can be found at https://github.com/DUNE- DAQ/appfwk/wiki/Compiling-and-running-under-v2.2.0

Environmental variables

We want to work with a specific tag/version, and within a specific working directory. In our example, we use:

export VERSION=dunedaq-v2.2.0

export MYDIR=dunedaq

Setup daq-buildtools

Set up daq-builtools via your shell:

git clone https://github.com/DUNE-DAQ/daq-buildtools.git -b $VERSION
source daq-buildtools/dbt-setup-env.sh

The expected answer is

Added /your/path/to/daq-buildtools/bin to PATH
Added /your/path/to/daq-buildtools/scripts to PATH
DBT setuptools loaded

Setup working directory

mkdir $MYDIR
cd $MYDIR
dbt-create.sh $VERSION

This may take a couple of minutes and will create your working area in the $MYDIR location.

Setting up modules

DUNE DAQ consists of several mod- ules. The most important one is appfwk that provides the basic func- tionalities. The data selection is based on two modules: triggermodules and triggeralgs. The source code for the modules are located in sourcecode. Following commands can be run to check out all the required modules:

cd sourcecode
MODULES="appfwk triggermodules triggeralgs cmdlib ers filecmd listrev restcmd"
for MODULE in $MODULES
do
git clone https://github.com/DUNE-DAQ/$MODULE.git
cd $MODULE
git fetch;git checkout $VERSION
cd ..
done

You should now have a complete working environment!
