[!] Possibly broken imlib2 / libgif detected - ignoring test results Imlib2 1.4.7 is unable to load GIF images on Debian stretch/sid systems (and maybe other distros too). On x86 / x86_64 this applies to most gifs which are not the first file in the filelist, while on mips/mipsel and (some?) arm boxes it is unable to load any gif files. Since feh's tests include gifs, they fail. As there's nothing we can do about it (and other image formats still work fine), we'll just pretend everything's okay. See for details.
