RE: multiple levels of substitution in msi

["Allison, Stephanie" <saa@slac.stanford.edu>]

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}
}
