c - makefile 文件格式无法识别

Question

我做错了什么？您能否发送一些有用的链接，让我的 makefile 工作更轻松、更好？

get_next_line.o: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
Makefile:27: recipe for target 'gnl' failed
make: *** [gnl] Error 1

SRC = gnl.c
OBJ = $(SRC:.c=.o)
INCLUDES = gnl.h
NAME = gnl
CFLAGS = -Wall -Werror -Wextra
CC = gcc
DIR = LIBFT

%.o: %.c $(SRC) $(INCLUDES)
        $(CC) $(CFLAGS) -c $<

all: $(NAME)

$(NAME): $(OBJ)
        make -C $(DIR)
        $(CC) $(CFLAGS) -o $(NAME) $(OBJ) -L. $(DIR)/libft.a
clean:
        make clean -C $(DIR)
        rm -f $(OBJ)

fclean:
        make fclean -C $(DIR)
        rm -f $(NAME)

re: fclean all

Answer 1

这本身不是 make 错误。它说

get_next_line.o: file not recognized: File format not recognized

所以那是你的问题。不知何故，您设法在您的目录中有一个损坏的 .o 文件。删除它，事情会变得更好。
