#   Makefile for the Stanford GraphBase
#

#   Be sure that CWEB version 3.0 or greater is installed before proceeding!

#   Skip down to "SHORTCUT" if you're going to work only from the
#   current directory. (Not recommended for serious users.)

#   Change SGBDIR to the directory where all GraphBase files will go:
SGBDIR = ${PREFIX}

#   Change DATADIR to the directory where GraphBase data files will go:
DATADIR = $(SGBDIR)/lib/sgb

#   Change INCLUDEDIR to the directory where GraphBase header files will go:
INCLUDEDIR = $(SGBDIR)/include

#   Change LIBDIR to the directory where GraphBase library routines will go:
LIBDIR = $(SGBDIR)/lib

#   Change BINDIR to the directory where installdemos will put demo programs:
BINDIR = $(SGBDIR)/bin

#   Change CWEBINPUTS to the directory where CWEB include files will go:
CWEBINPUTS = $(SGBDIR)/lib/cweb

#   SHORTCUT: Uncomment these lines, for single-directory installation:
#DATADIR = .
#INCLUDEDIR = .
#LIBDIR = .
#BINDIR = .
#CWEBINPUTS = .

#   Uncomment the next line if your C uses <string.h> but not <strings.h>:
#SYS = -DSYSV

#   If you prefer optimization to debugging, change -g to something like -O:
CFLAGS = -g -I$(INCLUDEDIR) $(SYS)

########## You shouldn't have to change anything after this point ##########
