No such file or directory error when using make

I am still relatively new to Linux, but I have an assignment in my operating systems class that involves several files. My professor gave us his makefile, but it isn't working for me. Make just returns errors. I know that I have all of the same files as my professor and, although mine aren't done yet, there is no reason I see for the code to not compile.

Here is the Makefile:

sync: sync.c prodcons.c prodcons.h producer.c producer.h consumer.c consumer.h Makefile
        ${CC} -g -Wall -pthread -o  sync ssync.c prodcons.c producer.c consumer.c ln -sf sync assn4

and here is the error message I am getting:

J_studentid@cs3060:~/assn4$ make
cc -g -Wall -pthread -o sync sync.c prodcons.c producer.c consumer.c ln -sf sync assn4
cc: error: ln: No such file or directory
cc: error: sync: No such file or directory
cc: error: assn4: No such file or directory
cc: error: unrecognized command line option ‘-sf’; did you mean ‘-Hf’?
Makefile:2: recipe for target 'sync' failed
make: *** [sync] Error 1
J_studentid@cs3060:~/assn4$

I saw the professor compile and run the code in class, so I know it has the potential to work, but it is giving me problems. I am more than happy to provide more information or code, but I don't think the contents of the files is relevant to the compilation errors. Thank you!

I am pretty sure that this is the intended source code of your makefile that is both valid and working:

all:
    ${CC} -g -Wall -pthread -o  sync ssync.c prodcons.c producer.c consumer.c
    ln -sf sync assn4

Issues with your makefile were:

  1. No default target, i.e. missing all:
  2. ln -sf sync assn4 were used as compiler arguments

Also, please make sure that the command lines (e.g., ${CC} ...) always start with a TAB character. I cannot tell whether there was some in your codeblock since they are changed to spaces automatically here but wanted to point out.
