Hi,

The perl script makeDbDepends.pl has been changed with EPICS Base

R3.14.12.2. Now the script works and produces a file like this one:

$ cat O.linux-x86/iocLlrf.db.d

../O.Common/iocLlrf.db: llrfSim.db llrfLabview.db llrf.db llrfCavUp.db

llrfCavTune.db llrfAcq.db

../O.Common/iocLlrf.db :

With previous EPICS Base versions the file looked like this:

$ cat O.linux-x86/iocLlrf.db.d
../O.Common/iocLlrf.db:

The first build works but the second build fails because the file

iocLlrf.db.d exists:

$ make
make -C O.linux-x86 -f ../Makefile TOP=../../.. T_A=linux-x86 install
make[1]: Entering directory `/home/lussi/tmp/topSP2/llrfApp/db2/O.linux-x86'

make[1]: *** No rule to make target `llrfSim.db', needed by

`../O.Common/iocLlrf.db'. Stop.

make[1]: Leaving directory `/home/lussi/tmp/topSP2/llrfApp/db2/O.linux-x86'
make: *** [install.linux-x86] Error 2

I tried to correct this with the patch found in the 3.14.12.2 known

problems (rules-db.patch) and with the patch proposed by Bruce Hill, but

none works for me.

My file iocLlrf.db is built from iocLlrf.substitutions. The substituted

db files are located in my $(TOP)/db. But this location is not known by

the make command. So I tried to modify the file RULES.Db this way:

vpath %.db $(USR_VPATH) $(GENERIC_SRC_DIRS) $(dir $(DB)) $(TOP)/db

But this modification introduces a circular dependency problem and it

doesn't work.

For the moment I have no alternative but to use a 'make rebuild'.

If someone can help.
Thank you in advance.

Yves
