[mythtv-users] How to compile mainserver.cpp?

Actually I just finished doing this myself, thanks to your post with
the link to the changes required.  Mine compiled without a hitch, and
then I simply copied the mythbackend binary over top of the stock 0.16
one in /usr/bin.

IIRC you have the correct process, but I'm sorry to say I don't know
what those errors are caused by.  Are you sure you have all the
prerequisites installed?
