Requirements

Software:

• CentOS 7/8, Alma 9
• cmake 3.14 or higher
• GCC version 9
  • for example from devtoolset-9
• Some misc packages (can be installed via yum):
  • gnuplot
  • texlive-epstopdf
  • zeromq, zeromq-devel (for netio controller)
  • boost-devel for BDAQ
  • ROOT for plotting tools

Quick minimal Install Guide:

• Builds spec and emu controller for mininmal dependencies on Centos 7
• Build recipes for other OS can be found in docker//Dockerfile
• Clone from git
  • $ git clone https://gitlab.cern.ch/YARR/YARR.git Yarr
• Compilation:
  • $ source scl_source enable devtoolset-9
  • cd Yarr
  • $ cmake3 -S ./ -B build or $ cmake3 -S ./ -B build -DYARR_CONTROLLERS_TO_BUILD=all
  • $ cmake3 --build build -j4
  • $ cmake3 --install build -j4
• Running
  • execute programs from the repository top folder

Building additional controllers

• In order to build with more controllers execute cmake with extra options
  • For all controllers:
    • -DYARR_CONTROLLERS_TO_BUILD=all
  • For NetIO:
    • -DYARR_CONTROLLERS_TO_BUILD="Spec;Emu;NetioHW"

While developing, it might be useful to run some unit tests. These are run by default in the CI on gitlab, but can also be run locally:

• cd build
• make test

This runs the test_main binary, which gathers the tests found in src/tests.
