This is probably partly upstream and partly a local issue. While building mythtv on a headless machine that will act as a backend only I came across this build error: Calculating dependencies Please note, this ebuild does not use your CFLAGS and CXXFLAGS. It determines a sane set and uses those. Please do not attempt to override this behavior. >>> Unpacking source... >>> Unpacking mythtv-0.18.1.tar.bz2 to /var/tmp/portage/mythtv-0.18.1/work >>> Source unpacked. ./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-altivec --disable-audio-oss --disable-audio-alsa --disable-audio-arts --disable-audio-jack --disable-lirc --disable-joystick-menu --disable-xvmc-vld --disable-dvb --disable-dvb-eit --dvb-path=/usr/include --disable-opengl-vsync --enable-vorbis --disable-xvmc --disable-xv --disable-directfb --enable-x11 --enable-proc-opt --disable-mmx --compile-type=release --disable-distcc WARNING: include the output of ./configure along with any bug report, when using a processor optimized build. # Basic Settings Compile type release Compiler cache no DistCC no Install prefix /usr CPU x86 (AMD Athlon(tm) Processor) Big Endian no MMX enabled no Vector Builtins no # Input Support Joystick menu no lirc support no ivtv support yes FireWire support no DVB support no [/usr/include] # Sound Output Support OSS support no ALSA support no aRts support no JACK support no # Video Output Support x11 support yes xrandr support yes xv support no XvMC support no XvMC VLD support no OpenGL vsync no DirectFB no Creating config.mak and config.h --8<--- snip g++ -o mythprogfind main.o -L/usr/qt/3/lib -L../../libs/libmyth -L../../libs/libmythtv -L../../libs/libavcodec -L../../libs/libavformat -lmythtv-0.18.1 -lmythavformat-0.18.1 -lmythavcodec-0.18.1 -lmyth-0.18.1 -lfreetype -lmp3lame -L/usr/X11R6/lib -lqt-mt -lXext -lX11 -lm -lpthread g++ -o mythepg main.o -L/usr/qt/3/lib -L../../libs/libmyth -L../../libs/libmythtv -L../../libs/libavcodec -L../../libs/libavformat -lmythtv-0.18.1 -lmythavformat-0.18.1 -lmythavcodec-0.18.1 -lmyth-0.18.1 -lfreetype -lmp3lame -L/usr/X11R6/lib -lqt-mt -lXext -lX11 -lm -lpthread ../../libs/libmyth/libmyth-0.18.1.so: undefined reference to `XineramaIsActive'../../libs/libmyth/libmyth-0.18.1.so: undefined reference to `XineramaQueryScreens'../../libs/libmyth/libmyth-0.18.1.so: undefined reference to `XineramaQueryExtension'collect2: ld returned 1 exit status make[2]: *** [mythprogfind] Error 1make[2]: Leaving directory `/var/tmp/portage/mythtv-0.18.1/work/mythtv-0.18.1/programs/mythprogfind'make[1]: *** [sub-mythprogfind] Error 2 make[1]: *** Waiting for unfinished jobs....../../libs/libmyth/libmyth-0.18.1.so: undefined reference to `XineramaIsActive'../../libs/libmyth/libmyth-0.18.1.so: undefined reference to `XineramaQueryScreens'../../libs/libmyth/libmyth-0.18.1.so: undefined reference to `XineramaQueryExtension' collect2: ld returned 1 exit statusmake[2]: *** [mythepg] Error 1make[2]: Leaving directory `/var/tmp/portage/mythtv-0.18.1/work/mythtv-0.18.1/programs/mythepg' make[1]: *** [sub-mythepg] Error 2make[1]: Leaving directory `/var/tmp/portage/mythtv-0.18.1/work/mythtv-0.18.1/programs'make: *** [sub-programs] Error 2 !!! ERROR: media-tv/mythtv-0.18.1 failed.!!! Function src_compile, Line 121, Exitcode 2!!! emake failed!!! If you need support, post the topmost build error, NOT this status message. ...done! The USE flags were minimal, in line with a headless machine: specifically -xv. The link fails because the Xinerama library is not included. The Mythtv configure script will only insert libXinerama if Xv is enabled. This, I think, is an upstream issue. Building with USE=xv sets --enable=xv but is overridden by the configure script if libXv is not found. LibXv is only present if X was built with USE=xv. Perhaps the ebuild should check this is the case in the same way it checks mysql support in Qt. Reproducible: Always Steps to Reproduce: 1. Attempt to build mythtv-0.18.1 with USE=-xv 2. 3. Actual Results: The software should build with any of the optional configure flags, specifically --disable-xv set. It does not. Building Mythtv with USE=xv is not sufficient if X was not built with USE=xv. The ebuild does check this. Expected Results: Build even with Xv disabled. Check for xv in X if USE=xv is specified for mythtv.

The real issue is, you can't build X with USE="minimal". Try it out.
I know for sure it's the fact that you built xorg-x11 with USE=minimal. It won't work.
(In reply to comment #2) > I know for sure it's the fact that you built xorg-x11 with USE=minimal. It won't > work. If I _had_ built X with USE=minimal then you might have a point. Until you made this statement I had not even heard of a "minimal" USE flag. When I said minimal I meant a small set of the relevant USE flags: as reflected in my "emerge --info". More specifically, [ebuild R ] x11-base/xorg-x11-6.8.2-r1 -3dfx +3dnow +bitmap-fonts -cjk -debug -dlloader -dmx -doc -font-server* -hardened -insecure-drivers -ipv6 -minimal +mmx +nls -opengl +pam -sdk +sse -static +truetype-fonts +type1-fonts (-uclibc) -xprint -xv 0 kB Regardless of how X is built, Mythtv will not build if --disable-xv is specified (as it is in the ebuild if USE=-xv) because the inclusion of Xinerama libraries in linking is conditional on Xv support and some components like mythprogfind use Xinerama functions (unguarded). Even with USE=xv Mythtv will continue to fail to build unless X was built with USE=xv because Mythtv configure overrides the --enable-xv when it doesn't find the Xv library. I suggest we should check for this prerequisite in the ebuild just as we do for Qt and mysql.
We anxiously await your patch.
Message should be printed now.
