# Makefile for AHFinderDirect src/util library
# $Id: Makefile,v 1.2 2001-06-17 17:23:10 jthorn Exp $
#
# This Makefile can be called either as part of a Cactus build
# (in which case it expects the usual Cactus Makefile variables to be
# set), or directly from the command line (in which case it provides
# default values for some variables).
#
# Arguments:
# SRCDIR = Directory where the source code lives. Default is .
# if variable isn't set from command line or environment.
# CC, CXX = C and C++ compilers. Defaults are gcc and g++ if
# variables aren't set from command line or environment.
# CC_FLAGS, CXX_FLAGS = C++ compiler flags. Defaults are
# -I.. $(JT_GCC_FLAGS) -g
# and
# -I.. $(JT_GXX_FLAGS) -g
# if variables aren't set from command line or
# environment.
#
# Targets:
# lib ==> build libahfutil.a in the current directory
# from all source files except test*
# test ==> build test programs
# clean ==> delete object files, test drivers
# superclean ==> delete object files, test drivers, !library!
#
# Bugs:
# - Dependencies on *.hh are omitted.
