gcc compiler error when using certain switches

Question

I'm trying to compile a simple "Hello, World" program using gcc in C programming language. I use the following command on a source code file "test.c" (without the quotes).

I use the following command:

gcc test.c -O -Wall -Werror test

I expect this to compile my program and create and executable called test that I can run the program with from the command line. However when I compile using the above line I get the following error:

gcc: test: No such file or directory

Any reason as to why this may be?

Thanks!

Answer 1

gcc is treating test as an input file name. Assuming you want to use test as the output file name, you need to use the -o option.

gcc test.c -O -Wall -Werror -o test
                            ^^

Answer 2

You are giving the wrong commands to gcc:

do this :

gcc -Werror -Wall -O -o test test.c 

-o is for output
