# Makefile for building files in The Java Cookbook (O'Reilly, 2001, Ian Darwin)
# $Id: Makefile,v 1.24 2002/02/21 23:40:53 ian Exp $

# The use of Make in this tree has been deliberately kept VERY simple
# so it can work on BSD make, GNU make, Solaris make, etc., etc.,
# all of which have different "include" and other rule formats.
# The only "modern" make feature used is "?=".

# Pick a Java compiler. Any Java compiler that works.
#JAVAC=	javac
#JAVAC=	guavac
#JAVAC=	kaffe
#JAVAC=	jikes +E
# Make sure the user picked one.
JAVAC?= javac

MAKE?=	make		# could also be gmake, nmake, ...
SHELL=	/bin/sh

# There are three types of Makefiles in SUBDIR/*. Most of them
# are not in CVS, but are copied from Makefile.simple by "make makefiles"
# The few listed here, dirs that don't own a Makefile but need special one:
SUBDIRS_WITH_ERROR_DEMOS= introspection language numbers oo netweb
# are similarly copied by "make makefiles" from "Makefile.exclude-errors";
# these directories have source files (discussed in the book) that show
# why certain features won't compile without change.
# The third type are hand-maintained; these are for those that
# either need a "checkpath" rule similar to the one in this Makefile,
# or have other special needs.
