好吧我在我的makefile中有2個可變參數。我想遍歷變量中的文件並應用如下的變換。Makefile將文件名更改爲隱藏文件
cmain.cpp -> .cmain.depend
src/source.cpp -> src/.source.depend
我怎麼會去前面加上一個.到文件名的開頭和更改擴展名取決於用make？我想要轉換的數組由下面描述。
ALLSRC=$(shell find . -name '*.cpp')
ALLSRC := $(shell find . -name '*.cpp')
#Get the filenames without the directory so we prepend the . to the right thing
FNAME := $(notdir $(ALLSRC))
#Add the .
FNAME := $(FNAME:%=.%)
#Put the directory names back
HIDDEN := $(join $(dir $(ALLSRC)),$(FNAME))
HIDDEN := $(HIDDEN:%=%.depend)
#Equivalent one liner
HIDDEN2 := $(patsubst %,%.depend,$(join $(dir $(ALLSRC)),$(patsubst %,.%,$(notdir $(ALLSRC)))))
.PHONY: all
all: $(HIDDEN)
# Copies the file in this example, but $< and [email protected] contain the before and after names, so you can do whatever you want to.
.%.depend : %
cp "$<" "[email protected]
