I see a bunch of discussion about versioned symbols, mostly on Debian lists. But I don't see discussion on how to implement it in libraries. Can you offer a pointer (e.g., a URL) on how to convert libraries to use versioned symbols for those of us who sometimes write libraries? It looks like very little actually does it this way currently, but it would be nice to learn how. -- Jeff Jeff Abrahamson <http://www.purple.com/jeff/> +1 215/837-2287 GPG fingerprint: 1A1A BA95 D082 A558 A276 63C6 16BF 8C4C 0D1D AE4B Attachment:
