[MPlayer-users] Trying to compile for different CPU.

That's a pentium pro feature. Shouldn't be a problem on an mmx machine. I
wouldn't think.

Cross-compiling? Shouldn't have to cross compile. Your using the x86
architecture I would hope on both
machines. Just disable all the optimization stuff that doesn't apply to your
target CPU.

Don't really know for sure. But that line seems contradictory. The original
pentium machine does not have mmx. So I doubt you could enable mmx on a
classic pentium. Which might be what you are asking your compiler to do.
Can't be done. Bear in mind that the mplayer configure script is not a
regular auto configure script. Enabling
a feature will enable that feature whether or not it is a logical request.

Yeah, your list of  configure  options grows quite long and since I'm  aging
as I'm reading
your list of options, Alzheimer's disease is probably setting in. :-)

Oh, my soul. RedHat. I'd go with Debian Stable.
