The real answer to this is: learn how to write a simple makefile. You can
find some quick tutorials on the web. It seems intimidating, but although
makefiles *can* get really complicated, a basic one is very simple. You have
a list of things you want to make, and for each thing, a list of the steps
to make it. (Really, the biggest gotcha is the strange syntax, where
indentation *must* be done with tabs.)
Or, since you're staring from scratch, you could use scons, which is
designed as a more modern replacement for make. It's included in Fedora
Extras.
A simple SContruct file for your "filename.c" would look like this:
Program('filename.c')
and that's it (no indentation, though). You'd then type "scons" to build it.
Hmmm -- on my system, I don't need to link in libm explicitly to get sqrt()
-- it just works. But if you *do* need a library, do this:
Program('filename.c',LIBS='m')
