I get the same output when I call gcc without any file names, so it looks like gcc is working.

Try gcc file.c on a file with some c code. If the code is correct, it should produce an executable file called a.out.

It is indeed installed

Try the command below and see your current version

> gcc --version

Next go find a tutorial on GCC or read the manual
