Stephanie,

If I change

#13 Makefile to:

    TOP=../../..
    include $(TOP)/configure/CONFIG

DB = second.db

include $(TOP)/configure/RULES

DBFLAGS += $(TOP)/db

but I can't seem to get DBFLAGS to appear automatically.

Is there a way to debug the RULES building part of the build process?

Hi John,

Your rule for inflating the database isn't properly using DBFLAGS so it doesn't have the directories with "db" in the include list. Is it possible you are using a rule that is different from the one in base/configure/RULES.Db?

Here is an example from my build (I have several modules included in my RELEASE which is why the long list of potential areas to find database files):

Inflating database from ../evrEventAll.substitutions /nfs/slac/g/lcls/build/epics/extensions/extensions-R3-14-8-2/bin/linux-x86/msi -I. -I.. -I ../../../../db -I /nfs/slac/g/lcls/build/epics/modules/generalTime/generalTime-R1-2-1/db -I /nfs/slac/g/lcls/build/epics/modules/sSubRecord/sSubRecord-R1-0-1/db -I /nfs/slac/g/lcls/build/epics/modules/miscUtils/miscUtils-R1-0-1/db -I /nfs/slac/g/lcls/build/epics/base/base-R3-14-8-2-lcls2/db -I../O.Common -S../evrEventAll.substitutions > msi.tmp
mv msi.tmp ../O.Common/evrEventAll.db


If you are using your own rule, you may need to add the "db" in front of the file name. For example:

file db/firstAll.db {
pattern { DEVICE }
{ device1 }
{ device2 }
...
{device30}
}

Allison,

Using your suggestion (from January) I tried unsuccessfully to get MSI to do multiple levels of substitution. I am using 3.14.9 but I assume that is not the issue.

Setup:

#1  xxx
#2     Makefile
#3     configure/
#4     iocBoot/
#5     xxxApp/
#6        Makefile
#7        Db/
#8           first/
#9              Makefile
#10             firstAll.substitutions
#11             firstAll.template
#12          second/
#13             Makefile
#14             second.substitutions
#15       src/


Fails with:


    Inflating database from ../second.substitutions
    msi   -I. -I.. -I../O.Common -S../second.substitutions  > msi.tmp
    Could not open firstAll.db


firstAll.db exists but not in any of the places MSI is looking. How do I get MSI to find it?


Details:

#6 Makefile is:

    TOP=../..
    include $(TOP)/configure/CONFIG

    DIRS += first
    DIRS += second

include $(TOP)/configure/RULES_DIRS


#9 Makefile is:


    TOP=../../..
    include $(TOP)/configure/CONFIG

DB = firstAll.db

include $(TOP)/configure/RULES

#13 Makefile is:

    TOP=../../..
    include $(TOP)/configure/CONFIG

DB = second.db

include $(TOP)/configure/RULES


Thanks,

Hi John,

Is there a way to get MSI to deal with multiple levels of substitution?
I divide my Db directory into sub-directories and build
them in the proper order. For example:
xxxApp/Db/first contains Makefile, first.db, and
firstAll.substitions:
Makefile has:
DB += firstAll.db
firstAll.substitutions which looks something like this:
file first.db {
pattern { DEV , CARD , NAME , ID
,P0,P1,P2,P3,P4,P5,P6,P7,P8,P9,P10,P11,P12,P13,VME}
{ $(DEVICE) , 0 , NAME1 , 1 , 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0 , 0 , 0 , 0 , 1 }
{ $(DEVICE) , 0 , NAME2 , 2 , 1, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0 , 0 , 0 , 0 , 1 }
...
{ $(DEVICE) , 0 , NAME15 , 12 , 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0 , 0 , 0 , 1 , 1 }
	}	
	

xxxApp/Db/second contains Makefile, second.substitutions:
Makefile has:
DB += second.db
second.substitutions looks something like this:
file firstAll.db {
pattern { DEVICE }
{ device1 }
{ device2 }
...
{device30}
}


and xxxApp/Db/Makefile looks like:
TOP = ../..
include $(TOP)/configure/CONFIG
# first must be first since second will need for the
.db file created by first
DIRS += first DIRS += second
include $(TOP)/configure/RULES_DIRS


The RULES.Db files that come with epics 3.14.8.2 will do
the MSI properly - I don't think we had to change RULES.Db for this.
If you don't like sub-directories, just create more *Db
directories under xxxApp:
xxxApp/CommonDb1
xxxApp/CommonDb2
xxxApp/Db (which depends on CommonDb1 and CommonDb2
being built first)
xxxApp/Makefile must enforce proper build order

Note there is a bug in the RULES somewhere that requires
the "{" that comes after the "file xxxx.db" to be on the next line if xxxx.db comes from another module listed in your RELEASE file.
Doesn't work:
file xxxx.db {
Works: file xxxx.db
{


Hope this helps more than confuses...
