#  Usage:
#       Either edit this Makefile to un-comment the options you want, or
#       override the options by environment or command-line variables.
#       For example:
#
#    setenv BIN      Linux2_x86_64ifort
#    setenv BASEDIR  /wherever/I-ve/un-tarred/the/code
#    setenv CPLMODE  nocpl
#    make
#
#  or:
#
#    make BIN=Linux2_x86_64pg  CPLMODE=pncf INSTALL=/foo/bar
#    
#.........................................................................
#  Environment/Command-line Variables:
#
#       BIN     machine/OS/compiler/mode type. Shows up as suffix
#               for "$(IODIR)/Makeinclude.$(BIN)" to determine compilation
#               flags, and in $(OBJDIR) and $(INSTALL) to determine
#               binary directories
#
#       INSTALL installation-directory root, used for "make install":
#               "libioapi.a" and the tool executables will be installed
#               in $(INSTALL)/$(BIN)
#
#       LIBINST overrides  $(INSTALL)/$(BIN) for libioapi.a
#
#       BININST overrides  $(INSTALL)/$(BIN) for M3TOOLS executables
#.........................................................................
#  Directories:
#
#       $(BASEDIR)  is the root directory for the I/O API library source,
#                   the M3Tools and M3Test source,the  HTML documentation,
#                   and the (machine/compiler/flag-specific) binary
#                   object/library/executable directories.
#       $(HTMLDIR)  is the web documentation
#       $(IODIR)    is the I/O API library source
#       $(TOOLDIR)  is the "M3TOOLS" source
#       $(OBJDIR)   is the current machine/compiler/flag-specific
#                   build-directory
#       $(INSTALL)  installation-directory root, used for "make install":
#                   "libioapi.a" and the tool executables will be installed
#                   in $(INSTALL)/$(BIN) object/library/executable directory
#.........................................................................
# Note On Library Versions and configuration:
#
#       Environment variable "BIN" specifies library version up to
#       link- and compile-flag compatibility.  Dependecies upon machine,
#       OS, and compiler are found in file "Makeinclude.$(BIN)".
#       Command-line "make BIN=<something>..." overrides environment
#       variable "% setenv BIN <something>" which overrides the
#       make-variable default below.
#
#       IN PARTICULAR, pay attention to the notes for various versions
#       that may be built for Linux x86 with the Portland Group
#       compilers:  see comments in $(IODIR)/include 'MAKEINCLUDE'.Linux2_x86pg
#.........................................................................
# Special Make-targets
#
#       configure:  "Makefile"s, with the definitions indicated below.
#       all:      OBJDIR, FIXDIR, libioapi.a, and executables, with
#                 the current mode.
#       lib:      OBJDIR, FIXDIR, libioapi.a
#       clean:    remove .o's, libioapi.a, and executables from OBJDIR
#       rmexe:    remove executables from OBJDIR
#       relink:   rebuild executables from OBJDIR
#       install:  copy "libioapi.a" and executables to $(INSTDIR)
#       dirs:     make OBJDIR and FIXDIR directories
#       fix:      FIXDIR and extended-fixed-source INCLUDE-files
#       gtar:     GZipped tar-file of the source and docs
#       nametest: test of name-mangling compatibility (requires that
#                 libnetcdff.a be manually placed into $(OBJDIR))

#      ----------   Definitions for "make configure"  ------------------
#
#  VERSIONING DEFINITIONS:  the preprocessor definitions in $(IOAPIDEFS)
#  (below) govern I/O API behavior; versions with distinct combinations
#  of these options are NOT library- nor object-compatible and should
#  be built in *distinct*  $(OBJDIR)s:
#
#       Defining IOAPICPL turns on PVM-enabled "coupling mode" and
#       requires "libpvm3.a" for linking.
#
#       Defining IOAPI_PNCF turns on PnetCDF based distributed I/O
#       and requires libpnetcdf.a and libmpi.a for linking; it should
#       be used only with an MPI-based ${BIN} (e.g., Linux2_x86_64ifortmpi)
#
#       Defining IOAPI_NCF4 turns on full netCDF-4 interfaces, including
#       support for INTEGER*8 variables and attributes.  It requires
#       extra libraries for linking, which can be found by running the
#       commands  "nf-config --flibs" and "nc-config --libs"
#
#       Defining IOAPI_NO_STDOUT suppresses WRITEs to the screen in
#       routines INIT3(), M3MSG2(), M3MESG(), M3PARAG(), and M3ABORT().
#       This also helps control the "double-printed-message" behavior
#       caused by recent SGI compilers.
#
#       Defining IO_360 creates the 360-day "global climate" version
#       of the library.
#
#       Defining BIN3_DEBUG turns on trace-messages for native-binary
#       mode routines.
######################################################################
#      ----------   Default/fall-back Definitions --------------------
#      For POSIX "make", environment variables override these; 
#      variable setting on the command line ("make VAR=VALUE ...")
#      overrides that.
#
#      GNU "make" DOES NOT FOLLOW POSIX, AND INSTEAD DOES ITS OWN
#       WRONG-HEADED THING, MAKING IT IMPOSSIBLE TO HAVE DEFAULTS
#       THAT ARE THEN OVER-RIDDEN BY THE ENVIRONMENT !!
