2. How do I setup my bash shell to use the new EPICS?From a bash shell on an ICD Development host (e.g. lcls-dev2 for 32-bit; lcls-dev3 for 64-bit), type the following: source /afs/slac/g/lcls/epics/setup/go_epics_3-14-12-4_1-0.bash The above script sets up several EPICS environment variables in your bash shell. It is recommended that in the .bashrc script, you add a case statement to check for development hosts and source the epics setup so that this step is automatic upon login. Some enviroment variables that are now avilable to you are paths to ' 'TOP-level' directories of interest. Below are a few examples : EPICS_TOP=/afs/slac/g/lcls/epics/R3-14-12-4_1-0 EPICS_BASE_TOP=/afs/slac/g/lcls/epics/R3-14-12-4_1-0/base EPICS_MODULES_TOP=/afs/slac/g/lcls/epics/R3-14-12-4_1-0/modules EPICS_EXTENSIONS=/afs/slac/g/lcls/epics/R3-14-12-4_1-0/extensions/extensions-R3-14-12 EPICS_IOC_TOP=/afs/slac/g/lcls/epics/R3-14-12-4_1-0/iocTop EPICS_MBA_TEMPLATE_TOP=/afs/slac/g/lcls/epics/R3-14-12-4_1-0/modules/icdTemplates/icdTemplates-R1-2-0 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/R3-14-12-4_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. |
