## TARGETS: below here we describe the target dependencies and rules
##
all: $(A3EXE)

$(A3EXE): $(A3OBJS) $(AALIB)
	$(CC) $(CFLAGS) -o $(A3EXE) $(A3OBJS) $(AALIB)


## The ar(1) tool is used to create static libraries.  On Linux
## this is still the tool to use, equivalent to libtool(1). 
$(AALIB): $(AALIBOBJS)
	ar rcs $(AALIB) $(AALIBOBJS)
	

## convenience target to remove the results of a build
clean :
	- rm -f $(A3OBJS) $(A3EXE)
	- rm -f $(AALIBOBJS) $(AALIB)


## tags -- editor support for function definitions
tags : dummy
	ctags *.c aalib/*.c

## a "dummy" dependency forces its parent to run always
