Reed-Solomon Encoding/Decoding

[Matthew]

There are many posts in the archive of this group and others as well
as in the FAQ about implementations of Reed-Solomon in both C and C++.
Unfortunately, all of the discussion is from the mid to late 90s and
link and emails all seem to be dead ends at this point (someone should
probably pull the FAQ link).

Can anyone point me to public domain source code in C or C++
(preferred) for Reed-Solomon encoding/decoding?

See the Error Correcting Codes page, http://www.eccpage.com/

On there, there is http://www.eccpage.com/rs.c
It's not Public Domain, but its license amounts to "credit the author".

Matthew,
I strongly suggest Phil Karn's implementation

I personally used in my error-resilent LZ-77 and it works perfectly.
