To build any examples; - in /configure/RELEASE: EPICS_BASE and MOTOR must be defined. - in /Makefile: the following three lines must be uncommented; #!DIRS += motorExApp iocBoot #!motorExApp_DEPEND_DIRS = motorApp #!iocBoot_DEPEND_DIRS = motorExApp To build this simulation example; - in /configure/RELEASE: ASYN must be defined. - in /iocBoot/iocSim/Makefile set the target architecture Finally, cd ; gnumake clean uninstall; gnumake To run this simulation example on a Unix OS; - Set the EPICS_HOST_ARCH environment variable correctly. - Edit the st.cmd.unix file for either sun or linux. - Start the ioc from this directory by executing the following command. ../../bin/${EPICS_HOST_ARCH}/WithAsyn st.cmd.unix
