If a static pattern rule matches a target, then it generates warnings
to override the generic static pattern rule with a specialized rule.
For example:
$(O_FILES): %.o: %c
cc -c $< -o $@
alpha.o: %.o
cc -c $< -o $@ -DFOO
This particular feature of static patterns rules is worse than
implicit rules.
Also, not a question of interaction, but a real limitation
in gnu make 3.79.1 at least: static pattern rules don't allow
free use of the "%" character in constructing dependencies.
For example:
$(O_FILES): %.o: %.c $(dep_list_%)
Here is a complete sample Makefile attached to illustrate both
these problems.
===
C_FILES := $(wildcard *.c)
O_FILES := $(patsubst %.c,%.o,$(C_FILES))
dep_list_alpha := alpha.h
dep_list_beta := beta1.h beta2.h
dep_list_gamma := gamma.h
a.out: $(O_FILES)
cc $(O_FILES) -o $@
$(O_FILES): %.o: %.c $(wildcard %*.h) $(dep_list_%)
cc -c $< -o $@
alpha.o:
cc -c $< -o $@ -DFOO
