Hi there,

after installing a new system yesterday i ran into a problem today while trying to install firefox (source version) and thunderbird.
The reason is imho that ffmpeg cant be installed.

For both firefox and thunderbird im getting the following message when im trying to emerge them (also input of emerge --info):

Any idea whats wrong here? Perhaps i used wrong C-Setting for my make conf? Was checking them in the USE-flag wiki and couldn't see any problems yet...

My cpu is a Intel 6700k.

In make.conf add
Code:
CPU_FLAGS_X86="mmx sse sse2 mmxext"

This because mmx cpu-flag require mmxext for ffmpeg package

By the way you should expand CPU_FLAGS_X86 with all the possible flags for your CPU. You can get them by installing app-portage/cpuid2cpuflags
