So, I switched to myth-0.22 awhile back because I finally got a sane database. No thanks to the mythtv guys, many thanks to the Gentoo guys for pointing out the bad behavior of mythtv not checking encoding formats and just assuming. I had been trying out the SVN version because 0.22 was broken in Portage. Long story short I haven’t been able to build mythvideo for months. Today I finally tried looking at the build log and internet searching. For reference here are the first few errors in the log file:
In file included from metadata.cpp:8:
/usr/local/include/mythtv/mythcontext.h:9:22: error: qptrlist.h: No such file or directory
In file included from main.cpp:18:
/usr/local/include/mythtv/mythcontext.h:9:22: error: qptrlist.h: No such file or directory
/usr/local/include/mythtv/mythcontext.h:13:23: error: qnetwork.h: No such file or directory
/usr/local/include/mythtv/mythcontext.h:13:23: error: qnetwork.h: No such file or directory
I stumbled upon someone else who couldn’t build that was getting similar errors to mine http://mythtv.org/pipermail/mythtv-users/2008-November/238546.html The problem was that the prefix for SVN is /usr/local/ whereas the ebuild prefix is /usr/ The quick and dirty solution:

mv /usr/local/include/mythtv /usr/local/include/mythtv-old
ln -snf /usr/include/mythtv /usr/local/include/mythtv

That solved the problem immediately, but I think the real problem is the ebuild. I checked the mythtv ebuild and the prefix is defined as /usr/, but the mythvideo ebuild does not have a prefix defined. I believe the solution is to define the prefix in the ebuild or make the symlink in the ebuild for mythtv.

Either way, I’m super-stoked! Now I can get back to encoding everything to something besides MPEG2 and watching it with mythtv instead of xine or mplayer.
