Camserv won't compile, this is a common problem these days apparently. New versions off glibc or gcc or whatever its called are apparently less tolerant of missing bits than the older verions. If you download camserv do "./configure", then "make install" and it fails with a bunch of Call to undefined functions messages, talking about errno then its because the following line is missing from the top of some of the files.
To solve the problem then go to the .c files that won't compile and add the above next to the other #induce lines and that file will compile fine. This include relay/relay.c, camserv/main_loop.c and camserv/camserv.c They may have been others I had to modify too.
Hope this helps!
