Bug 27284 – gst-plugins-0.6.2-r1 fails to compile with "-march=pentium4"

• Product: Gentoo Linux
• Status: RESOLVED WONTFIX

[Description Hypnos 2003-08-25 04:02:52 UTC]

When I remove "-march=pentium4" from my CFLAGS (leaving "-mcpu=i686 -Os -pipe"),
the package builds fine.  Otherwise, I get an error concerning an illegal "movd"
assembly instruction when the "goom" plugin is compiling.  

Some possibly useful info:

* gcc = 3.2.3-r1, glibc = 2.3.2-r1, binutils = 2.14.90.0.2

* I use all the USE flags considered by the ebuild _except_ "aalib", "arts" and
"sdl"



Reproducible: Always

please give your 'emerge info' as requested in the bugform (the one for dummies) and some more complete output maybe, where we can see what is actually going on.

Very well -- emerge info is below, and build log is attached:

 Build log for gst-plugins-0.6.2-r1

[Comment 4 foser (RETIRED) 2003-08-25 06:13:11 UTC]

You positively have a pentium4 ?

The problem is not reproducable by the gstreamer people.

[Comment 5 Brandy Westcott (RETIRED) 2003-08-25 16:23:40 UTC]

I have a pentium4 and can confirm that gst-plugins does not compile 
using the same CFLAGS as Sourav. I narrowed it down to a collision 
between -mcpu=i686 and -march=pentium4 which makes this bug 
seem quite similar to http://bugs.gentoo.org/show_bug.cgi?id=25461 
 

[Comment 6 Hypnos 2003-08-25 18:27:10 UTC]

Yes, it's a Pentium 4 Mobile, according to /proc/cpuinfo and the machine specs.

[Comment 7 foser (RETIRED) 2003-08-26 02:18:31 UTC]

hmmm well, so there's not much todo about this. I'm tempted to close it as WONTFIX cause i don't think adding flagstripping for every possible situation is a good thing to do (and gst-plugins already strips a whole lot of stuff).

[Comment 8 Mike Gardiner (RETIRED) 2003-08-27 05:41:33 UTC]

i can't reproduce this on a normal (non Mobile) p4, testing the CFLAGS provided by the reporters emerge info.

[Comment 9 Hypnos 2003-08-27 12:24:38 UTC]

FYI, I tried re-emerging binutils to rebuild the assembler, to no avail.

[Comment 10 foser (RETIRED) 2003-09-21 10:55:22 UTC]

hmm yeah well, i'm about to close this as WONTFIX. It probably isn't even a gst problems problem per-se, but it looks like it happens in the imported goom code.

It only happens with the cpu->march combo i think. You could try install xmms-goom and see if it shows the same behaviour (the codebase should be partialy the same).

Any last comments before i close it down ?

[Comment 11 Hypnos 2003-09-21 14:56:32 UTC]

Yes, go ahead and close it -- we'll see what happens with the impending 0.7.0 release, as there have been a ton of changes.

[Comment 12 foser (RETIRED) 2003-09-22 04:37:43 UTC]

the 0.7 series won't go in the tree, it's a development series. And i really doubt thats the problematic code here : it's probably imported goom code.

[Comment 13 Hypnos 2003-09-22 08:19:39 UTC]

Looking at my installation database, I got 0.6.3 to install with full flags without any problems.

I think it's safe to close this bug.

[Comment 14 foser (RETIRED) 2003-10-05 03:37:15 UTC]

ill reproducable, closing
