# Makefile by Landon Curt Noll


# The shell used by this Makefile
#
# On some systems, /bin/sh is a rather reduced shell with
# deprecated behavor.
#
# If your system has a up to date, bash shell, then
# you may wish to use:
#
#	SHELL= /bin/bash
#
# On some systems such as macOS, the bash shell is very
# far behind to the point wehre is cannot be depended on.
# On such systems, the zsh may be a much better alternative
# shell for this Makefile to use:
#
#	SHELL= /bin/zsh
#
SHELL= /bin/sh
#SHELL= /bin/bash
#SHELL= /bin/zsh


####
# Normally, the upper level makefile will set these values.  We provide
# a default here just in case you want to build from this directory.
####

# Normally certain files depend on the Makefile.  If the Makefile is
# changed, then certain steps should be redone.  If MAKE_FILE is
# set to Makefile, then these files will depend on Makefile.  If
# MAKE_FILE is empty, then they wont.
#
# If in doubt, set MAKE_FILE to Makefile
#
MAKE_FILE= Makefile

# Controlling file makefile basename (without the path)
#
# This is the basename same of the makefile that may/does/will drive
# this makefile.
#
# If in doubt, set TOP_MAKE_FILE to Makefile
#
TOP_MAKE_FILE= Makefile

# Where the system include (.h) files are kept
#
# For DJGPP, select:
#
#	INCDIR= /dev/env/DJDIR/include
#
# If in doubt, set:
#
#	INCDIR= /usr/include
#

#INCDIR= /usr/local/include
#INCDIR= /dev/env/DJDIR/include
INCDIR= /usr/include

# where to install calc related things
#
# ${BINDIR}		where to install calc binary files
# ${LIBDIR}		where calc link library (*.a) files are installed
# ${CALC_SHAREDIR}	where to install calc help, .cal, startup, config files
#
# NOTE: The install rule prepends installation paths with ${T}, which
#	by default is empty.  If ${T} is non-empty, then installation
#	locations will be relative to the ${T} directory.
#
# For DJGPP, select:
#
#	BINDIR= /dev/env/DJDIR/bin
#	LIBDIR= /dev/env/DJDIR/lib
#	CALC_SHAREDIR= /dev/env/DJDIR/share/calc
#
# If in doubt, set:
#
#	BINDIR= /usr/bin
#	LIBDIR= /usr/lib
#	CALC_SHAREDIR= /usr/share/calc
#
#BINDIR= /usr/local/bin
#BINDIR= /dev/env/DJDIR/bin
BINDIR= /usr/bin

#LIBDIR= /usr/local/lib
#LIBDIR= /dev/env/DJDIR/lib
LIBDIR= /usr/lib

#CALC_SHAREDIR= /usr/local/lib/calc
#CALC_SHAREDIR= /dev/env/DJDIR/share/calc
CALC_SHAREDIR= /usr/share/calc

# By default, these values are based CALC_SHAREDIR, INCDIR, BINDIR
# ---------------------------------------------------------------
# ${HELPDIR}		where the help directory is installed
# ${CALC_INCDIR}	where the calc include files are installed
# ${SCRIPTDIR}		where calc shell scripts are installed
#
# NOTE: The install rule prepends installation paths with ${T}, which
#	by default is empty.  If ${T} is non-empty, then installation
#	locations will be relative to the ${T} directory.
#
# If in doubt, set:
#
#	HELPDIR= ${CALC_SHAREDIR}/help
#	CALC_INCDIR= ${INCDIR}/calc
#	SCRIPTDIR= ${BINDIR}/cscript
#
HELPDIR= ${CALC_SHAREDIR}/help
CALC_INCDIR= ${INCDIR}/calc
SCRIPTDIR= ${BINDIR}/cscript

# T - top level directory under which calc will be installed
#
# The calc install is performed under ${T}, the calc build is
# performed under /.	The purpose for ${T} is to allow someone
# to install calc somewhere other than into the system area.
#
# For example, if:
#
#     BINDIR= /usr/bin
#     LIBDIR= /usr/lib
#     CALC_SHAREDIR= /usr/share/calc
#
# and if:
#
#     T= /var/tmp/testing
#
# Then the installation locations will be:
#
#     calc binary files:	/var/tmp/testing/usr/bin
#     calc link library:	/var/tmp/testing/usr/lib
#     calc help, .cal ...:	/var/tmp/testing/usr/share/calc
#     ... etc ...		/var/tmp/testing/...
#
# If ${T} is empty, calc is installed under /, which is the same
# top of tree for which it was built.  If ${T} is non-empty, then
# calc is installed under ${T}, as if one had to chroot under
# ${T} for calc to operate.

# Form the builtin file
#
# We have a "chicken-and-egg" problem.  We want the builtin help file to
# accurately reflect the function list.	 It would be nice if we could
# just execute calc show builtin, but calc may not have been built or
# build-able at this point.  The hack-a-round used is to convert ../func.c
# into a stand-alone program that generates a suitable function list
# that is sandwiched between the top and bottom builtin help text.
#
# We form funclist.c by sedding out unwanted stuff from builtins table,
# converting NUMBER* and VALUE into harmless types and converting
# the showbuiltins() function into main().  Combined with the -DFUNCLIST
# we will avoid all of the complex calc types, macros and defines and
# be left with just main() and a minimal builtins table.
