With ~amd64 when compiling kvm with USE="sdl" I had a little problem, it failed with error: in check_evdev.c [...] SDL_[...] not found after installing xf86-input-evdev _AND_ recompiling libsdl it compiled and worked So we will need a evdev input_device flag for libsdl to check correctly with kvm. Reproduce steps: emerge -C xf86-input-evdev emerge libsdl kvm Reproducible: Always Steps to Reproduce: 1. emerge -C xf86-input-evdev 2. emerge libsdl kvm 3.
Please post your "emerge --info" and attach the build.log file of the failed emerge to this bug. Reopen this bug when you provide the requested information.
