The sed command the ebuild uses to disable Xv when the xv useflag is not set is insufficient. Reproducible: Always Steps to Reproduce: 1. Build xorg-x11 with USE="-xv" 2. Build mythtv with USE="-xv" Actual Results: emerge of mythtv dies missing -lXv Expected Results: emerge of mythtv succeeds not needing -lXv The ebuild contains the following snippet: ==(snip)=== if ! use xv ; then sed -e 's:CONFIG += using_xv:#CONFIG += using_xv:' \ -e 's:EXTRA_LIBS += -L/usr/X11R6/lib:#EXTRA_LIBS += -L/usr/X11R6/lib:' \ -i 'settings.pro' || die "disable xv failed" fi ===(/snip)=== However, this is insufficient. after doing this, settings.pro still contains this snippet: ===(snip)=== # Default Xv support #CONFIG += using_xv EXTRA_LIBS += $$LOCAL_LIBDIR_X11 -lXinerama -lXv -lX11 -lXext -lXxf86vm ===(/snip)=== I have commented out that EXTRA_LIBS line. I am still rebuilding mythtv right now. If it works, I will prepare a patch.
Created attachment 56106 [details, diff] patch to ebuild to successfully disable xv I don't remember how I worked around this in 0.17, but for 0.17-r1 this change to the ebuild worked for me. Commenting out the whole EXTRA_LIBS line caused it to fail looking for Xinerama, so I just took out the "-lXv" part.
Fixed in 0.18.
