 Posted: Wed Aug 16, 2006 2:11 am Post subject: Quick question concerning mplayer |
 |
|
Just another random gentoo newb, lol... had a few rough spots, but so far everything is going great. I do have one question, though.
I've emerged mplayer, and noticed that it claims to be compiled for an "x86" processor. Is this normal when compiled for amd64? I've doublechecked my CFLAGS (march is k8, which should be synonymous with athlon64, right?) and re-emerged, and the same thing is reported. Is this in fact a 64-bit compilation? Wouldn't it be reporting a different target processor? It's not a huge deal, as it works fine, but I'm concerned I may have something set wrong somewhere and built a largely 32-bit system with few of the benefits thereof, lol. |

My MPlayer seems to be ok:
| Quote: | MPlayer 1.0pre8-3.4.6 (C) 2000-2006 MPlayer Team
CPU: AMD Athlon(tm) 64 Processor 3500+ (Family: 15, Model: 47, Stepping: 2)
CPUflags: MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 1
Compiled with runtime CPU detection. |
| Quote: | #file /usr/bin/mplayer
/usr/bin/mplayer: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped |
You should have something like this in your make.conf
| Quote: | CFLAGS="-march=athlon64 ..."
CHOST="x86_64-pc-linux-gnu" |
And yes, gcc man page gives an impression that k8 = opteron = athlon64 = athlon-fx. |

Hey, that 'file' command is really handy, lol. It is, indeed, a 64 bit executable, and thanks for the effort. For future reference, what confused me is:

but 'file' reports that it is in fact a 64 bit executable. Good enough for me *grin*. Thanks, all. |
