Hi,

in case someone is still interested in this approach, the rule in my previous
email doesn't work anymore with EPICS 3.15.x.

I had to append to database Makefile the following snippet:

FLATDB = /path/to/VisualDCT/flatdb.sh
DBDLIST := $(foreach dbd_dir,$(DBD_SEARCH_DIRS),$(patsubst %,-d %,$(wildcard
$(dbd_dir)/*.dbd)))

%.db$(DEP): %.vdb
        @$(RM) $@
        $(ECHO) "$<: \\" > $@

%.db$(DEP): ../%.vdb
        @$(RM) $@
        $(ECHO) "$<: \\" > $@

$(COMMON_DIR)/%.db: %.vdb
        $(ECHO) "Generating flat database from $<"
        @$(RM) $(notdir $@)
        @$(FLATDB) $(DBDLIST) $< $(notdir $@) > /dev/null
        @$(MV) $(notdir $@) $@

$(COMMON_DIR)/%.db: ../%.vdb
        $(ECHO) "Generating flat database from $<"
        @$(RM) $(notdir $@)
        @$(FLATDB) $(DBDLIST) $< $(notdir $@) > /dev/null
        @$(MV) $(notdir $@) $@

Cheers,

Luca
