the standard build of feh has no zoom/rotation (normaly when you hold the middle mouse button on a picture and move the mouse, the zoom effect is immediate, here nothing happens) After a short investigation, the problem seems to be in imlib2. It's built on an amd64 system, it has most use flags when building it with emerge : ebuild R ] media-libs/imlib2-1.4.6-r2 USE="X bzip2 gif jpeg mp3 nls png zlib -doc (-mmx) -static-libs -tiff" ABI_X86="(64) (-32) (-x32)" 0 kB and despite this I get at the end of configure : Use X86 MMX for speed.....: no Use AMD64 for speed.......: no disabling mmx in amd64 mode is normal, but amd64 assembly should be enabled. I compiled it manually to check this, and when I ran configure I had "use amd64 for speed = yes" of course, without passing any special parameter to configure, and after installing it, feh retrieved its very fast zoom ! Reproducible: Always Steps to Reproduce: 1.emerge -av imlib2 on an amd64 system 2.Check the configure summary at the end (should have "use amd64 for speed = yes") 3. eventually check feh zoom with middle mouse button + mouse move on a picture
Please post your emerge --info. For whatever reason the 'mmx' flag is disabled in your profile

Ok this is the reason arch/amd64/package.use.mask:media-libs/imlib2 mmx mmx flag is masked on imlib2 because of: # Jeremy Olexa <darkside@gentoo.org> (07 Feb 2009) # USE=mmx on imlib2 causes issues with other apps. See bug 218382 (comments # 11-12) media-libs/imlib2 mmx CC'ing Jeremy
You can force unmask it yourself if you want to. Closing as duplicate of 218382 *** This bug has been marked as a duplicate of bug 218382 ***
