im a gentoo newbie!
i just set up my first gentoo box!
i compiled everything and everything goes ok but...
i notice that my mplayer says:
"mmx2 supported but disbled"
of course my cpu is a p3 600Mhz and i set the flag mmx & sse in USE but
i didn't find nothing about a mmx2 or sse2 flag....
are they exist?
if so... it is convenient set em up and recompile mplayer? and what about
other progs (such as xmms, ogg, lame....) ?

There is a list of _general_ USE flags in the text file
/usr/portage/profiles/use.desc

Some applications support additional flags; you can find them by looking
for the IUSE line in the ebuild file, e.g. -

[watch out for line wrapping:]
> grep IUSE grep IUSE /usr/portage/media-video/mplayer/mplayer-1.0_pre5-r5.ebuild
Or you can use -

> emerge -vp mplayer

and it will show you the flag settings in use. (-v for "verbose", -p for
"pretend")

Of course, you should only enable hardware-support flags such as mmx2
if your processor actually supports it.
