2. How do I setup my bash shell to use the new EPICS?From a bash shell in an LCLSDEV host (Ex. lcls-dev2), type the following: source /afs/slac/g/lcls/epics/setup/go_epics_3-14-12-3_1-0.bash The above script sets up several EPICS environment variables in your bash shell. Some variables are paths to ''TOP-level' directories: EPICS_TOP=/afs/slac/g/lcls/epics/R3-14-12-3_1-0 EPICS_BASE_TOP=/afs/slac/g/lcls/epics/R3-14-12-3_1-0/base EPICS_MODULES_TOP=/afs/slac/g/lcls/epics/R3-14-12-3_1-0/modules EPICS_EXTENSIONS=/afs/slac/g/lcls/epics/R3-14-12-3_1-0/extensions/extensions-R3-14-12 EPICS_IOC_TOP=/afs/slac/g/lcls/epics/R3-14-12-3_1-0/iocTop EPICS_MBA_TEMPLATE_TOP=/afs/slac/g/lcls/epics/R3-14-12-3_1-0/modules/icdTemplates/icdTemplates-R1-0-1 PACKAGE_TOP=/afs/slac/g/lcls/package EPICS_IOC_TOP is the top level application directory for all EPICS iocs that use this EPICS version. It is here where all new EPICS applications must be created. EPICS_IOC_TOP is the same as the APP variable. Other environment variables setup in your bash shell are: IOC=/afs/slac/g/lcls/epics/R3-14-12-3_1-0/iocCommon $IOC is the directory where the startup scripts for all the iocs are located. IOC_DATA=/nfs/slac/g/lcls/epics/ioc/data $IOC_DATA is the data directory. This is where the outputs (and in some case inputs) from iocs are stored. |
