# Makefile for compiling PoZeTools version 0.52.
# Pieter Suurmond, march 31, 2005.
# Should work on Linux, freeBSD, Mac OSX, SGI IRIX, etc.

# Names of the 4 executable binaries:
PRG_CONSOLE  = PZT
PRG_CGI      = cgi/nph-PZT.cgi
PRG_CGI_FREQ = cgi/nph-freq.cgi.jpg
PRG_CGI_TIME = cgi/nph-time.cgi.jpg

# Simly type 'make' to only build the commandline application:
default: $(PRG_CONSOLE)

# Type 'make cgi' to only build the 3 CGI executables (for 
# an online filter design service on your UNIX-webserver):
cgi: $(PRG_CGI) $(PRG_CGI_FREQ) $(PRG_CGI_TIME)

# Type 'make all' to compile all the PoZeTools binaries:
all: $(PRG_CONSOLE) $(PRG_CGI) $(PRG_CGI_FREQ) $(PRG_CGI_TIME)

# Some ancient versions of 'make' don't understand that the objects 'gt.o' and 
# 'pieter_cgi.o' are meant to be placed in their subdirectories ('gt' and 'cgi') 
# during compilation. The newer (GNU) 'makes' understand this, but here, we 
# explicitly instruct old 'makes' to do so. Neither of them needs the math-lib.
