I think the wiki is out of date and depending upon what options you pass to the autobuild script it will fail on dependencies check - I know for sure that the dvb-tools package isn't listed as a dependency but it is and the build fails without it.
This is the ./configure options to build TVHeadend exactly as the repositories provide it;
./configure --build=x86_64-linux-gnu --prefix=/usr --includedir=${prefix}/include --mandir=${prefix}/share/man --infodir=${prefix}/share/info --sysconfdir=/etc --localstatedir=/var --disable-silent-rules --libexecdir=${prefix}/lib/tvheadend --disable-maintainer-mode --disable-dependency-tracking --enable-libffmpeg_static --enable-hdhomerun_static --enable-dvbcsa --enable-bundle --arch=x86_64
NOTE: This does NOT package the build into a .deb file but if it's to be installed on the same server that built it then that doesn't matter. If you do need to package the build up, use;
AUTOBUILD_CONFIGURE_EXTRA='--prefix=/usr --includedir=${prefix}/include --mandir=${prefix}/share/man --infodir=${prefix}/share/info --sysconfdir=/etc --localstatedir=/var --disable-silent-rules --libexecdir=${prefix}/lib/tvheadend --disable-maintainer-mode --disable-dependency-tracking --enable-libffmpeg_static --enable-hdhomerun_static --enable-dvbcsa --enable-bundle' ./Autobuild.sh -t debian
Again using Autobuild has it's own list of dependencies which are again not listed in the wiki. When I get a moment I will provide the full dependencies list to build/package TVHeadend.
