如何避免Makefile中重复的隐式规则？

发布于 2024-12-27 03:26:17 字数 769 浏览 0 评论 0原文

我正在开发一个Makefile自动生成软件（CodeMate），我想知道我是否可以避免为不同的文件编写隐式规则就足够了，但具有相同的操作：

%.o: %.F90
    @echo " Creating dependency $@"
    @echo $(seperator)
    @$(FORTRAN_COMPILER) -c $< $(OPTION) $(FORTRAN_FLAGS) $(INCLUDES)
%.o: %.f90
    @echo " Creating dependency $@"
    @echo $(seperator)
    @$(FORTRAN_COMPILER) -c $< $(OPTION) $(FORTRAN_FLAGS) $(INCLUDES)
%.o: %.F
    @echo " Creating dependency $@"
    @echo $(seperator)
    @$(FORTRAN_COMPILER) -c $< $(OPTION) $(FORTRAN_FLAGS) $(INCLUDES)
%.o: %.f
    @echo " Creating dependency $@"
    @echo $(seperator)
    @$(FORTRAN_COMPILER) -c $< $(OPTION) $(FORTRAN_FLAGS) $(INCLUDES)

这可以很好地工作，但有点难看。

谢谢！

I am working on a Makefile auto-generating software (CodeMate), and I would like to know if I can avoid to write the implicit rules for different file suffices but with the same operations as:

%.o: %.F90
    @echo " Creating dependency $@"
    @echo $(seperator)
    @$(FORTRAN_COMPILER) -c lt; $(OPTION) $(FORTRAN_FLAGS) $(INCLUDES)
%.o: %.f90
    @echo " Creating dependency $@"
    @echo $(seperator)
    @$(FORTRAN_COMPILER) -c lt; $(OPTION) $(FORTRAN_FLAGS) $(INCLUDES)
%.o: %.F
    @echo " Creating dependency $@"
    @echo $(seperator)
    @$(FORTRAN_COMPILER) -c lt; $(OPTION) $(FORTRAN_FLAGS) $(INCLUDES)
%.o: %.f
    @echo " Creating dependency $@"
    @echo $(seperator)
    @$(FORTRAN_COMPILER) -c lt; $(OPTION) $(FORTRAN_FLAGS) $(INCLUDES)

This can work well, but is a little ugly.

Thanks!

（未经测试：）

define f_rule
%.o: %.$(1)
    @echo " Creating dependency $@"
    @echo $(seperator)
    @$(FORTRAN_COMPILER) -c $< $(OPTION) $(FORTRAN_FLAGS) $(INCLUDES)
endef

F_EXTENSIONS := F90 f90 F f
$(foreach ext, $(F_EXTENSIONS), $(eval $(call f_rule,$(ext))))

(Untested:)

define f_rule
%.o: %.$(1)
    @echo " Creating dependency $@"
    @echo $(seperator)
    @$(FORTRAN_COMPILER) -c $< $(OPTION) $(FORTRAN_FLAGS) $(INCLUDES)
endef

F_EXTENSIONS := F90 f90 F f
$(foreach ext, $(F_EXTENSIONS), $(eval $(call f_rule,$(ext))))
