Java Makefile

If you are interested in compiling your java code on a mac, or a unix/linux machine with the terminal, then using a Makefile may be helpful.

I found an easy to use Makefile here...

http://www.cs.swarthmore.edu/~newhall/unixhelp/javamakefiles.html

Remember that the indented lines must be TAB. If you copy/paste this code, the TAB's may become SPACES which would not work.

I am running mac OS 10.6.2 and using xcode to write my java programs. I compile and run them inside the mac terminal.

Here's my Makefile for JAC444 practice 1.

#
# define compiler and compiler flag variables
#

JFLAGS = -g
JC = javac


#
# Clear any default targets for building .class files from .java files; we
# will provide our own target entry to do this in this makefile.
# make has a set of default targets for different suffixes (like .c.o)
# Currently, clearing the default for .java.class is not necessary since
# make does not have a definition for this target, but later versions of
# make may, so it doesn't hurt to make sure that we clear any default
# definitions for these
#

.SUFFIXES: .java .class


#
# Here is our target entry for creating .class files from .java files
# This is a target entry that uses the suffix rule syntax:
# DSTS:
# rule
# 'TS' is the suffix of the target file, 'DS' is the suffix of the dependency
# file, and 'rule' is the rule for building a target
# '$*' is a built-in macro that gets the basename of the current target
# Remember that there must be a <> before the command line ('rule')
#

.java.class:
$(JC) $(JFLAGS) $*.java


#
# CLASSES is a macro consisting of 4 words (one for each java source file)
#

CLASSES = \
Student.java \
TestAStudent.java \
Ticket.java \
TestATicket.java


#
# the default make target entry
#

default: classes


#
# This target entry uses Suffix Replacement within a macro:
# $(name:string1=string2)
# In the words in the macro named 'name' replace 'string1' with 'string2'
# Below we are replacing the suffix .java of all words in the macro CLASSES
# with the .class suffix
#

classes: $(CLASSES:.java=.class)


#
# RM is a predefined macro in make (RM = rm -f)
#

clean:
$(RM) *.class
