Experimental Physics and
Industrial Control System

Hi Ernest,

the main issue behind this:
In the traditional EPICS build system, IOC startup files (actually everything under iocBoot) are considered source files. Other than for libraries, databases etc., these sources are not compiled in any way, and they do not create any products that are installed. Without an installation step, $(INSTALL_LOCATION) does not apply.

For our HZB/BESSY developments, we are creating the startup files programmatically in an ...App directory, so we changed our rules to treat .../iocBoot as an installation directory (much like lib, bin, ...), and install the created startup scripts there. In this setting, there is an installation step for these files, and $(INSTALL_LOCATION) works as expected.

Trying to select the relevant configuration parts....


Our CONFIG contains:

INSTALL_BOOT := $(INSTALL_LOCATION)/iocBoot
UNINSTALL_DIRS += $(INSTALL_BOOT)


The ...App Makefile uses this by setting:

IOCS = $( /* database call to get ioc names */ )
STCMD_INSTALLS = $(IOCS:%=$(INSTALL_BOOT)/ioc%/st.cmd)

build: $(STCMD_INSTALLS)

$(STCMD_INSTALLS): $(INSTALL_BOOT)/ioc%/st.cmd: $(COMMON_DIR)/st.cmd.%
        @echo "Installing $@"
        @$(CP) $< st.cmd
        @$(INSTALL) -d -m 644 st.cmd $(@D)
        @$(RM) st.cmd

$(COMMON_DIR)/st.cmd.%: ../%.st.cmd
        @$(CP) $< $@


Hope this shows the general direction...

Cheers,
~Ralph
