# For defgb 3.0 et seq; assumes jgofs 1.5 distribution and that this file,
#    along with the defgb sources, is in src/* under the jgofs root.
#    See below if this is not the case.
#    Further assumes that src/methods/outer.c includes .brev capability.
#    that src/include exists and contains "appropriate" .h files,
#    including the ones for outer.c

# A certain set of compilation constants for outer is assumed (see SWITCHES
#    defn below).  Additional constants can be specified by defining
#    ADDL_SWITCHES.  Different constants require redefinition of the
#    SWITCHES symbol (on command line or in environment along with the
#    -e make switch) or specification in ADDL_SWITCHES plus knowledge
#    about how multiple constant defns are handled.
# Flags for the compilation/load come from 3 sources.  The CC symbol
#    typically includes some flags.  CFLAGS is defined here.
#    ADDL_CFLAGS may be defined externally.  See comments for
#    ADDL_SWITCHES, above

# This file can be run standalone if:
#	1) METHOD is defined on make command line
#	2) jgofs_root/build-env.pl has been executed first in context of
#	   this process 
#	3) jgofs.a library has already been built
#    Note: can be used to create an image in any directory from any
#	directory by specifying any or all of METHBINDIR, OUTERSRCDIR,
#	LIBDIR, & SRCDIR on the command line

# If there is trouble porting the jgofs.a jdb routines, defgb
# can be built without them by specifying the compilation switch
#	-DREAD_OBJECTS=FALSE
# If there is trouble porting the startchild_defgb routine, defgb
# can be built without it by specifying the compilation switch
#	-DREAD_COMMANDS=FALSE
# See defgb_switches.doc for details about compilation switches
# See param1.doc for information about what defgb functionality is
# lost when these switches are specified

#	  coded

#	Return to the more precise distinction between compilation and linking
#	  courtesy of gcc's preference.  Libraries (and dependencies on
#	  libraries) belong in link commands (and image dependencies), not
#	  compilation commands (and object dependencies)
#   7 Jul 04.  WJS
#	master_makefile.defgb becomes makefile.defgb
#	Mods to take advantage of new build stuff (add ${CONFIG_FILE}, etc
#	  dependencies; build optdefgb, etc).  CONFIG_FILE (eg, build-env)
#	  is used to force builds in addition to its natural dependency role
#	Mod to use outer_make_macros.include
#  28 Apr 04.  WJS
#	Typo fixes
#	Get outer.h from OUTERINCDIR & define that to OUTERSRCDIR
#	Add utils.h dependency
#	INCDIR to TESTINCDIR
#  13 Feb 04.  WJS
#	defgb_utils in library, too
#	Allow two INCDIRs for testing.  MASTERINCDIR stays src/include
#  10 Feb 04.  WJS
#	Assume startchild_defgb, path_info_routines, &
#      outer_utils are in library.
#	Separate compilation for outer.o, taking outer.c and its support
#      files from src/methods, etc instead of .   Among other things,
#      OUTERBREVDIR is gone.
#   9 Jul 03.  Create per-method outer object file on logic that each
#	method compilation could have different -D switches.  WJS
#  24 Dec 02.  HAS_OUTER_INTEREST_ENTRY.  WJS
#   7 Jan 99.  USE_DOUBLE.  WJS
#   3 Dec 98.  Remove METHOD_PROTOTYPE.  WJS
#  17 Nov 98.  Add CLH mods anticipating include directory & testing for
#	existence of method directory before attempting creation.  WJS
#  11 Nov 98.  outer.h; outer_utils.c.  Taken from outer_brev's directory
#	for now.  Presumably will cause no harm if plain outer is being
#	used.  WJS
#  13 May 98.  Take outer.c from defgb distribution directory instead of from
#	JGOFS distribution location.  Assumption is that outer in defgb
#	distribution is outer_brev.  WJS
#  30 Jan 98.  ADDL_*S; SYS_LIBS
#	       Change METHOD_CFLAGS to CFLAGS. (Note: CFLAGS used to be
#	set in build or someplace (see the makefile for jgofs.a), but
#	doesn't seem to be set any more, so I glommed it)
#	       Put -lm in SYS_LIBS instead of CFLAGS.
#	       Typo fixes.  WJS
#  30 Sep 97.  A bit less defgb-specific.  Add SRCDIR, too
#  11 Sep 97.  More comments
#  11 Aug 97.  Change for use as include file.
#	       Remove incorrect build-env dependency.
#	       Parametrize various "components".  WJS
#  31 Jul 97.  Non-standard default.h (bigger TOKEN size for outer) and

#	compiling outer in its directory.
#	       Dependency on build-env so changes to *SERVER constants, etc,
