I would like someone to explain all the arguments given to gcc. I have not done much of C/C++ under *nix systems, though I know some of them.

If you man gcc you will probably find that -D sets a symbol as defined, -I gives an include path, -W sets warnings (all is all warnings), -O is optimizing, -f is I think some assembly coding stuff, -m is machine dependent stuff, -c is compile only, -o is output filename.

man gcc will tell you the right stuff.
