# SoftRelTools/objy_schema.mk
#
# Based on Scott Snyder's make files for CINT
#
# Include this before standard.mk to define rules to process
# Objectivity ddl files through ooddlx.
#
# You should/could define the following variables:
#
#   SCHEMA_DDL = List of ddl files to be processed.
#   SCHEMA_DDL_DIR = List of directories to search for files
#                    in SCHEMA_DDL. If not set, this defaults
#                    to the current directory.
#
#   OO_FD_BOOT = Path to the federated database boot file.
#                Other standard Objectivity variables 
#                (OO_LS_HOST, OO_FDID, OO_DB_JOU, OO_DB_PATH) 
#                should probaly also be defined.
#
#   OBJY_DIR = Path to the root directory of Objectivity (in
#              an UPS environment, that variables is usely set
#              by something like 'setup objy').
#
# You can inhibit actually running ooddlx by defining the 
# variable DONT_RUN_OODDLX. The dependencies on the schema
# files will still be properly honored.
#
# By default, the generated *_ddl.cc files are put in $(workdir).
# To put them somewhere else, define SCHEMA_SRCS_DIR. (If you put
# them somewhere other then either $(workdir) or the current 
# directory, you may want to do a `vpath %.cc $(SCHEMA_SRCS_DIR)' 
# somewhere.)
#
# By default, the generated *_ref.h and *.h files are also put
# in $(workdir).  To put them somewhere else, define 
# SCHEMA_HDRS_DIR.
#
# Bugs: Currently these files have only been tested on Solaris.
#       The options to redefine output directories have not been
#       tested through-fully (specialy SCHEMA_HDRS_DIR).
#
#       Input files should always have the extension .ddl
#       Output files will always have the extension .cc, .h
