Bug 28853 – Mplayer 1.0_pre1.ebuild uses -march|-mcpu = athlon-4 => illegal instruction

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Marc Hildebrand (RETIRED) 2003-09-16 01:23:14 UTC]

Hello!
Emerging the latest unstable ebuild (1.0_pre1) went fine, no errors.
Mplayer itself bails out with an illegal instruction.
After checking the ebuild and the Makefiles I found the CFLAGS -march=athlon-4
-mcpu=athlon-4. I'm using an Athlon XP.
In one of my former ebuilds I wrote a function that greps/cuts the -march and
-mcpu settings out of /etc/make.conf. I used this to pach mplayers config.mak.
It compiled with the settings I defined in /etc/make.conf (-march=i686
-mcpu=athlon-xp).
That binaries does not produce illegal instructions.
So I consider using athlon-4 a bug.

Tarball of maplayer compile logs, config.maks and the illegal instruction-error.

This is just logs, if anyone is interested...
I used them to grep athlon-4 and so on from the compile output.

Ebuild that fixes compile.mak (if athlon-4 was detected)

Please test this one.
It worked fine on my machine as well as on a pentium2 laptop.

marc did you send this upstream ?

gentoo doesn't use CFLAGS any more for mplayer

Ok, maybe I didn't make myself clear here.
Marty, I know that we don't use ouzr CFLAGS from make.conf in mplayer ebuilds.
That exactly is the problem (at least that's what I found out on my machine).
Mplayer's ./configure will detect my athlon-xp and uses -march=athlon4 which
is/was known to cause problems.
Dunno if it still does or if athlon4 is supportet in gcc3.2. My changes to
the ebuild just changed the mcpu/march settings.
If athlon4 is not a problem for athlon-xp users that's just fine. I know
why we don't use our CFLAGS settings and that's fine for me too.
The only thing I want to know is if anyone has had the same problems with
mplayer that I had. My machine was so borked (the famous "athlon-xp not knowing
nothing about sse" - problem), that it is very likely the whole affair is
my fault and has nothing to do with mplayer at all ;)
