我有我希望 Makefile 编译的文件列表,每种源语言都有一个列表:
CFILES= Src/Application/main.c Src/Core/data.c Lib/routines.c
ASFILES= Src/Application/startup.s Lib/sqrt.s

我希望所有输出都在一个目录中:
OBJDIR= output

我该如何做相当于:
output/main.o : Src/Application/main.c
cc -c -o output/main.o Src/Application/main.c
output/data.o : Src/Core/data.c
cc -c -o output/data.o Src/Core/data.c
output/routines.o : Lib/routines.c
cc -c -o output/routines.o Lib/routines.c
output/startup.o : Src/Application/startup.s
as -o output/startup.o Src/Application/startup.s
output/sqrt.o : Lib/sqrt.s
as -o output/sqrt.o Lib/sqrt.s

列表中每个文件的配方都是相同的。
输入文件位于各种不同的目录中,仅列出它们的文件名并使用搜索路径来查找它们是不可接受的,必须使用它们的显式路径。
输出文件名是源文件名的基本名称,扩展名更改为 o。不同源语言的列表之间不存在重复的基本名称。
我不想列出目标文件,这应该来自源列表。
我正在使用 gnu make,但是便携式解决方案的加分项。
像下面这样的事情可以做到:
all :
OBJDIR := output
CFILES := Src/Application/main.c Src/Core/data.c Lib/routines.c
ASFILES := Src/Application/startup.s Lib/sqrt.s
target = ${OBJDIR}/$(patsubst %.s,%.o,$(notdir ${1}))
obj.c :=
obj.s :=
define obj
$(call target,${1}) : ${1} | ${OBJDIR}
obj$(suffix ${1}) += $(call target,${1})
${1} : ; mkdir -p `dirname $$@` && touch $$@ # Create the source for testing. Remove this.
endef
define SOURCES
$(foreach src,${1},$(eval $(call obj,${src})))
endef
$(eval $(call SOURCES,${CFILES}))
$(eval $(call SOURCES,${ASFILES}))
all : ${obj.c} ${obj.s}
${obj.c} : % :
@echo cc -c -o $@ $^; touch $@ # echo and touch are for testing. Remove these.
${obj.s} : % :
@echo as -o $@ $^; touch $@ # echo and touch are for testing. Remove these.
${OBJDIR} :
mkdir $@
.PHONY: all
