I didn't actually look into the details, but a buddy of mine did, and claims this is due to the fact that we are running on Athlons. YMMV.

Created attachment 60416 [details] Build log I'm getting this on my athlon-mp system, a USE=frontendonly system. FWIW, the CFLAGS on the problematic system: CFLAGS="-march=athlon-mp -O3 -pipe" Working systems: CFLAGS="-march=athlon-xp -O3 -pipe" CFLAGS="-march=pentium3 -O3 -fprefetch-loop-arrays -funroll-loops -pipe" I've attached my full build log.
Useless console snippet... and a full build log... but no emerge info. Does no one read the instructions when posting bugs?

David, please re-open this - I've added the requested info. Thanks.
Reopened wrt Comment #4
can you try with march=athlon-xp instead of athlon-mp?
re #6: Done. With -march=athlon-xp that compiles. So, is that a problem upstream or with the ebuild? Is there a method for per-ebuild CFLAGS - I'd like to keep that flag for this SMP box. Thanks for your help, Brian.
(In reply to comment #7) > re #6: > > Done. With -march=athlon-xp that compiles. So, is that a problem upstream or > with the ebuild? It's a problem with how the configure script determines ARCH_X86, but you're seeing it now because we recently allowed more of the users CFLAGS through. > Is there a method for per-ebuild CFLAGS - I'd like to keep that > flag for this SMP box. afaik, the 2 flags don't make any difference, but we'll more than likely fix the problem with a patch, or use replace-flags in the ebuild which would work around it as well. > > Thanks for your help, Brian.
Brian, what do you say? We start patching up the configure script or just replace-flags?
Why don't we come up with a patch to fix a few, then send it upstream. Based on their reaction, we can decide if it's worth our time to continue, or just fall back to the easier, but more hackish replace-flags. You want me to whip up a quick patch to send upstream?
I'd like to just confirm that I get the same problem emerging mythtv-0.18.1, and I'm running dual Athlon MP 2800+ cpus, using the athlon-mp arch. Thanks for documenting that using -march=athlon-xp fixes this. That's good enough for me as long as I can find it with a quick bugs.gentoo.org search. Thanks all!
I had this problem with march=athlon-tbird but bumping it down to just march=athlon the problem went away.
If it helps, I also had the problem with athlon-tbird but when I changed "march" to i686, app-arch/cpio was updated to 2.6-r4 .

Created attachment 63815 [details, diff] Patch to add support for extra -march options. This problem is pretty similar to bug 94664. There was no support for x86_64 --arch options, I added a patch to handle these. The attached patch adds support for the missing x86 options as well as a few others I pulled from the gcc man page. It also adds an extra x86_64 option that I missed in the origional patch. This patch can replace the current mythtv-0.18.1-x86_64-configure.patch.
Fixed in 0.18.1-r2. Thanks. I've also redone it to work with upstream so it should be in the next release.
Cardoe: looks like you forgot to commit the actual patch * Cannot find $EPATCH_SOURCE! Value for $EPATCH_SOURCE is: * * /usr/portage/media-tv/mythtv/files/mythtv-0.18.1-cputypes-configure.patch * ( mythtv-0.18.1-cputypes-configure.patch )
And this is why we don't do things late at night. I commited a patch I was working on for other stuff rather then that patch. Oh well, it's fixed.
