This rule for %.o is, I believe, identical to the implicit rule. I always use something like: SOURCES := rotation.c or SOURCES := $(wildcard *.c) LDFLAGS += $(LIBS) OBJS := $(patsubst %.c,%.o,$(SOURCES)) BINS := $(patsubst %.o,%,$(OBJS)) default : rotation or default : $(BINS) % : %.o <tab>$(CC) -o $@ $< $(CFLAGS) $(LDFLAGS) If I'm using GNU make, I hardly ever use "=" instead of ":=", unless I really want to define a macro. You're a lot more likely to get what you expect most of the time, and you can use "+=". -- Michael A. Marsh http://www.umiacs.umd.edu/~mmarsh http://mamarsh.blogspot.com http://36pints.blogspot.com
