我已经在这个Makefile上工作了几个小时。它不断得到错误：make：***没有规则来建立目标“ hangman.c”，这是“ hangman.o”所需要的。停止

Question

CFLAGS=-std=c99 -Wall
CC=gcc

hangman: hangman.o hangman.c
    $(CC) $(CFLAGS) hangman.o hangman.c -o hangman

hangman.o: hangman.c
    $(CC) $(CFLAGS) -c hangman.c

clean:
    rm -f hangman *.o

Answer 1

尝试一下：

CFLAGS=-std=c99 -Wall
CC=gcc
OBJECTS = hangman.o

all: hangman

hangman.o: hangman.c
    $(CC) $(CFLAGS) -c hangman.c

hangman: $(OBJECTS)
    $(CC) $(OBJECTS) -o hangman

clean:
    rm -f hangman *.o
