Re: multiple levels of substitution in msi

[John Dobbins <john.dobbins@cornell.edu>]

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
