Description
We present a revived version of the CERNLIB, the basis for software
ecosystems of most of the pre-LHC HEP experiments. The efforts to
consolidate the CERNLIB are part of the activities of the Data Preservation
for High Energy Physics collaboration to preserve data and software of
the past HEP experiments.
The presented version is based on the CERNLIB version 2006 with numerous
patches made for the compatibility with modern compilers and operating systems.
The code is available publicly in the CERN GitLab repository with all
the development history starting from the early 1990s. The updates also
include a re-implementation of the build system in cmake to make CERNLIB
compliant with the current best practices and to increase the chances of
preserving the code in a compilable state for the decades to come.
The revived CERNLIB project also includes an updated documentation, which we
believe is a cornerstone for any preserved software depending on it.
Significance
CERNLIB has top importance for the Data Preservation in High Energy Physics as it is the basis software for the most of the pre-LHC HEP experiments.
The revival of the CERNLIB after more than 15 years of absence of maintenance is an example of the scientific software preservation and a source of lessons to learn for the benefits of ongoing software development and related physics experiments.
