make file issue:每行都有错误

Question

我尝试建立一个项目的库.当我从终端运行它作为./MakeFile时,每行都会收到一堆错误.下面是makefile和错误.这有什么问题？对于其他项目,Makefie工作正常,因此系统不知道如何解释此文件.谢谢!

LIBDIR = ../../lib

IFLAGS = -I../../include -I/usr/local/include

CFLAGS = $(IFLAGS) -O3 -Wunused -m32 #-fPIC

CC = gcc

AR = ar

SRC =   allocfailed.c cleanup.c ECDFwd.c ECDLeadField.c ECDSolve.c ECDSolve2.c \
    GetBasis.c  GetCoeffs.c GetHull.c NLeadField.c NSolveFwd.c NSolveWts.c \
    rnynm.c xbd.c xlubksb.c xludcmp.c

OBJ =   $(SRC:.c=.o)

all:    liblfu.a

liblfu.a: $(OBJ)
    $(AR) cr liblfu.a $(OBJ)
    @mkdir -p $(LIBDIR)
    mv liblfu.a $(LIBDIR)

clean:
    /bin/rm -rf *.o *.il *.a core

您正在将make文件作为脚本运行,只需键入即可 make

make命令将Makefile(或makefile)作为默认输入.它不可运行.

您可以通过添加使其可运行(假设make在/ usr/bin中)

#!/usr/bin/make -f

作为文件的第一行
