That runs a shell command in vi.
Emacs can do that also (M-!),
but for compiling, you want to use the emacs command:

M-x compile

you probably want to bind a key to that.

The main reason you want to do a compile is because the Emacs
functions next-error and previous-error work after a compile.

The M-x command by default runs the command "make -k".
You can just type your command over that.

I highly recommend creating a Makefile.
