Having played with zfec (more the underlying fec.[c,h] file) it's well written and self-contained as I remember it; but you will need to write a bunch of wrapper functions to chunk up data and pad out blocks and of course turn it into a library before you can use the underlying zfec implementation for ceph. If my memory is right, zfec's c code requires a C90 or C99 compiler to build it, I'm not sure if you care about that.
