[MPlayer-users] mplayer compilation error

[David C. Diemer]

BTW, just checked this web site: 
http://www6.tomshardware.com/cpu/99q3/990809/athlon-08.html

It seems to indicate that if you may already have MMX built-in, not 
necessarily the same as Intel's but it seems to be faster overall, but 
slower in multi-media. It also talks about 3D-NOW! and how that's supposed 
to revolutionize the processor. This article was written over 3 years ago!

Which Athlon are you using and let's follow that track for a quick 
information gathering.

Thanks David for your help.  I do appreciate it.

What will I lose in functionality if I disable post-processing?
Regarding my kernel's MMX support, recall in my original post these lines:

CLFAGS= ./configure --prefix=/usr --datadir=/usr/share/mplayer
        --confdir=/etc/mplayer --libdir=/usr/lib --enable-largefiles
        --disable-runtime-cpudetection --enable-mmx --enable-mmx2
        --enable-3dnow --enable-3dnowex --enable-sse --enable-sse2
        --enable-fastmemcpy --enable-freetype --disable-sighandler
        --enable-gui --enable-i18n --language=en --enable-linux-devfs

I assume that this indicates I have the needed support.  Or is there
something else.  Please note that this is an Athlon system, so
I am using the "mem=nopentium" boot option. I don't really
understand exactly what this does (except prevent system lock-ups)
but I recall that it has something to do with MMX.

Also, in one of my many many attempts to compile this things I did
disable the MMX/MMX2 and still got the errors.  They may have been in
a different place, but it was the same sort of error.  The place that
causes the error, by the way, is a swath of assembler code embedded in
the C-source code.  I wonder if this is an Athlon issue?

I'll try the --disable-shared-pp idea.

Holy Smokes!! is 3.4 out?  I just looked on Mandrake
Cooker and all they have is 3.2 dated Nov. 18 (which was
the last build date for that .src.rpm.  What happened
to 3.3?  Maybe this was just a typo?

Anyway, thanks.  I'm still waiting to hear from the fellow
who suggested it was gcc 3.2.  Maybe he knows something
I don't.
