## Makefile for the a60 interpreter (un*x version)
##

##
## Installation environment:
##
BINDIR = /usr/local/bin
LIBDIR = /usr/local/lib
MANDIR = /usr/local/man/man1
MANSUFF = 1

##
## Libdirpath is used in mkc.c; comment to exclude:
##
LIBDIRPATH = -DLIBDIRPATH=\"$(LIBDIR)\"

##
## Compiler environment:
##
## CC describes the compiler.
## (add -mnognu-stdarg for a gcc on a pyramid)
## XCC is the compiler used for X11. choose $(CC) for default, 
## and better cc on a sun.
##
#CC = gcc
XCC = $(CC)

##
## warn flags for gcc compiler:
##
GWARN = -W -Wcomment -Wpointer-arith -Wcast-qual
# GWAR2 = -Wall
WARN = $(GWARN) $(GWAR2)

##
## system dependent flags:
##
## define USG if compiling for a SystemV like machine (sorry).
##
## define VPRINTF_MISSING if vprintf is not avail.
## define REALLOC_MISSING if realloc is not avail.
## define ALLOCA_MISSING if alloca is not avail (used by bison only).
## define NO_LIMITS_H if the header limits.h is not avail.
## define NO_ENUMS if you have used `chenums' on *.h (see ENUM.README).
## define DEBUG for including general debug-code.
## define PARSEDEBUG for including parser debug-code.
## define MEMORY_STATISTICS for including runtime statistics code.
## define _POSIX_SOURCE (note leading _) on a POSIX or 4.4BSD box.
##
## appropriate DEFS for a sun:
# DEFS =
##
## appropriate DEFS for a pyramid:
# DEFS = -DVPRINTF_MISSING -DNO_LIMITS_H
##
## appropriate DEFS for POSIX:
DEFS = -D_POSIX_SOURCE -DALLOCA_MISSING

##
## Flags for debugging and production:
##
FLAGS = -pipe -g
# FLAGS = -O
#LDFLAGS = -g
# LDFLAGS = -s

## Uncomment for profiling:
# PROF = -pg

##
## library for math stuff:
##
LIBS = -lm

##
## Mainly used parser generator:
## (if you use bison, your compiler/libc should provide alloca)
##
BISONFLAGS = -v
BISON = bison -y
# BISON = byacc
# BISON = yacc

##
## Flags for lint:
##
LINTFLAGS = -q

# Allocate enough stack for the tests....ack(3,2) needs over 10k but
# less than 16k of stack.  I've made it 20k just to be sure.  I think
# the actual algol procedure stack frames are malloced so only the interpreter
# overheads count.
FLTFLAGS=-s 20000

PRG = a60

## How to build the target:
##
all:		$(PRG)

$(PRG):		$(OBJS)
	$(CC) $(LDFLAGS) $(PROF) -o $(PRG) $(OBJS) $(LIBS) $(LDLIBS)

romfs:
	$(ROMFSINST) /bin/a60
	$(ROMFSINST) -e CONFIG_USER_LANG_A60_EGS examples /home/a60-examples
	$(ROMFSINST) -e CONFIG_USER_LANG_A60_TEST test /home/a60-test

a60-ptab.c:	a60-parse.y
	$(RM) -f y.tab.c y.tab.h
	@echo '** expect 1 reduce/reduce conflict:'
	$(BISON) $(BISONFLAGS) -d a60-parse.y
	if [ -f y.tab.c ] ; then mv y.tab.c a60-ptab.c ; fi
	if [ -f y.tab.h ] ; then mv y.tab.h a60-ptab.h ; fi

##
## make the standalone xa60:
##

XINCLUDE = -I/usr/local/X11R5/include
XLIB = -L/usr/local/X11R5/lib  -lXaw -lXt -lXext -lXmu -lX11

xa60:		xa60.c
	$(XCC) $(XCFLAGS) $(XINCLUDE) -o xa60 xa60.c $(XLIB)

##
## the 'const' substitution prevents a 'keyword redefined' (for flex).
## the 'YYLMAX' is increased (for lex).
##
## (** a60-lex.l is replaced by a60-scan.c **)
##
LEX = flex
# LEX = lex
#

		-e '1,$$s/# define YYLMAX.*/# define YYLMAX 8192/'\
		< lex.yy.c > a60-ltab.c
	$(RM) -f lex.yy.c
