For any source code files, see: http://www-zeuthen.desy.de/linear_collider/cernlib/new/cernlib_2005.html Installation instructions: You may want to work in a dedicated CERNLIB directory since a large number of files are created (e.g. "mkdir /opt/CERN2005"). 1) wget http://www-zeuthen.desy.de/linear_collider/cernlib/new/cernlib-2005-all-new.tgz 2) tar -zxvf cernlib-2005-all-new.tgz 3) wget http://www-zeuthen.desy.de/linear_collider/cernlib/new/cernlib.2005.corr.2014.04.17.tgz 4) cp cernlib.2005.corr.2014.04.17.tgz cernlib.2005.corr.tgz 5) wget http://www-zeuthen.desy.de/linear_collider/cernlib/new/cernlib.2005.install.2014.04.17.tgz 6) tar -zxvf cernlib.2005.install.2014.04.17.tgz 7) See the "Notes:" in the "README_cernlib" file for installation procedures' requirements (i.e. required utilities and development files). See also the http://www-zeuthen.desy.de/linear_collider/cernlib/new/cernlib_2005.html web page for any additional installation hints which may appear there. 8) ./Install_cernlib_and_lapack ('tail -f 2005/build/log/make.MMDD' to monitor build) 9) Check all build logs for errors in the compilation process.
