Question

我有一个// "You have %d nickel" "You have %d nickels"看起来像这样，对于大多数目标都来自Makefile。但我想通过.o -> .bin -> .stub生成另一个更复杂的目标。

.o -> .elf -> .bin -> .stub

在构建all: simple.stub complex.stub %.bin: %.o $(Q)echo " OBJCOPY $@" $(Q)$(OBJCOPY) -O binary $< $@ %.stub: %.bin $(Q)echo " HEXDUMP $@" $(Q)$(HEXDUMP) -v -e '/2 "0x%04X, "' $< > $@ %.elf: %.o arm-none-eabi-gcc $< %@时如何告诉make .o -> .bin不是有效的转换，并阻止其他人通过complex.stub？

Answer 1

您需要告知make规则的例外情况，并提供备用模式规则，因为%.bin: %.elf没有内置规则

.PHONY: all
all: simple.stub complex.stub

.INTERMEDIATE: complex.bin complex.elf

complex.bin: complex.elf

%.bin: %.o
    @echo Making $@ from $^
    @echo "test" > $@

%.bin: %.elf
    @echo Making $@ from $^
    @echo "test" > $@

%.stub: %.bin
    @echo Making $@ from $^
    @echo "test" > $@

%.elf: %.o
    @echo Making $@ from $^
    @echo "test" > $@

%.o:
    @echo Making $@
    @echo "test" > $@

.INTERMEDIATE并非绝对必要，它只是一个有用的自动清理，因为它不太可能需要保留中间文件。

如何为单个目标添加额外的Makefile步骤？
