Re: Separate dirs for source (.c .java) and build files (.class .o)

[Alexander Farber]

Oops I've also noticed that I was violating Paul's rule no. 2
as I didn't have the file named $(BUILD)/'Pref$$1.class' (incl. quotes).
And thus Pref.jar was getting rebuilt every time.

So here is what I've ended up with sofar (still ugly):

CLASSES = $(CLIENT:%.java=$(BUILD)/%.class)

Pref.jar: $(MEDIA) $(CLASSES) $(BUILD)/Pref$$1.class
        jar cvf $@ $(addprefix media/, $(MEDIA)) \
        $(addprefix -C $(BUILD) , $(notdir $(CLASSES))) \
        -C $(BUILD) 'Pref$$1.class'

$(BUILD)/Pref$$1.class: Pref.java
        $(JAVAC) $(JFLAGS) -d $(dir $@) \
        -classpath $(dir $@) -sourcepath $(dir $<) $<

$(BUILD)/%.class: %.java
        $(JAVAC) $(JFLAGS) -d $(dir $@) \
        -classpath $(dir $@) -sourcepath $(dir $<) $<
