clang: error: unknown argument: '-wall'

I was walking through this tutorial, where I had to create this make file:

 CFLAGS=-wall  -g

 clean:
   rm  -f  ex1

I then used the above make file in this tutorial, and ran the following command:

$ make ex3

When I did that, I got the following output:

cc -wall  -g    ex3.c   -o ex3
clang: error: unknown argument: '-wall'
make: *** [ex3] Error 1

Why did I get the error? How can I fix it?

Thanks.

The option you're looking for is -Wall.

In general, options starting with -W indicate specific warnings or sets of warnings to enable or disable.
