Error in my makefile, flags are not treated appropriately. What can be the reason?

I have some issues with my makefile. I have the following source codes: main.c cache.c cache.h When I run make it is what I get...

  make
    gcc −ansi −pedantic −Wall −m32 -c main.c
    clang: error: no such file or directory: '−ansi'
    clang: error: no such file or directory: '−pedantic'
    clang: error: no such file or directory: '−Wall'
    clang: error: no such file or directory: '−m32'
    make: *** [main.o] Error 1

And here is my makefile:

COMPILER = gcc
CCFLAGS = −ansi −pedantic −Wall −m32
all:    c-sim
c-sim:  main.o cache.o
    $(COMPILER) $(CCFLAGS) -o c-sim main.o cache.o
main.o: main.c
    $(COMPILER) $(CCFLAGS) -c main.c
cache.o: cache.c
    $(COMPILER) $(CCFLAGS) -c cache.c

clean:
    rm -f c-sim
    rm -f *.o

What can be the issue here?

Don't write scripts with a word-processor.

The problem is that options start with a simple -. However, you've managed to enter typographical dashes. (Compare them with the - in -c. Your – are slightly longer. Look closely.)

This might be because you incorrectly typed -- instead of -. Gcc (and clang) allow but don't require long options (-pedantic and -ansi) to be specified with two dashes; that is the usual way of writing long options in other programs. Many word processors "correct" double dashes to an en-dash.

If you delete the en-dashes and replace them with simple single dashes, all will be well.

The Cause of the Problem is that you are not using GCC Compiler but using Clang compiler. In Clang flags are provided as :

/W0 /Wall

but GCC flags are provided as

-Wall -g

Thus you have change the flags according to Clang.
