I think this is because the "-mmmx" compiler switch is not present. You could try to add "-mmmx" to your CFLAGS and CXXFLAGS and see if that works. If so, the maintainer of the ebuild might consider to add something like the following line to the ebuild file: use mmx && append-flags -mmmx This worked at least for me (athon-xp architecture)...
Created attachment 54694 [details, diff] remove warnings and compile/link errors
well, I digged a bit deeper into the problem and found several things that go wrong, wspecially with gcc-3.4. I also found out that the compiler does not mark some "static" symbols as used, although they are used in inline assembler, which leads to unresolved symbols when linking. I attached a patch that should solve this, and also makes the source compile without warnings...
could you please update your patch for media-video/ffmpeg-0.4.9_p20050226-r2 ? Johnny
could you please remove -ftracer?
Hrmm.. bunch of test cases requested. I fixed most of the BREG errors with some pic patches. Closing as TEST-REQUEST and please let me know if things persist. Thanks for reporting and using Gentoo!
Did you change anything in the portage tree? I still have the same problems.
same problem with current ebuild in portage (ffmpeg-0.4.9_p20050226-r3) and mmx support enabled (by default in my system it is disabled, see #89172)
Well, I was able to merge ffmpeg. I did some dirty ahcks, an I don't know what I really did. Here's the lines from my bashhistory. Can somebody explain, what hte problem is? I called gcc manually.

As a workaround, it compiles fine without the "mmx" USE flag, but that's not really an acceptable solution. Could someone reopen this report? Thanks.
Hmm... With USE="-mmx" it compiles, altough I have -mmmx in my CFLAGS... I guess that would have to be enough until it's fixed (or until Thomas updates his patch :))...

Comment #17 is invalid report for me, turn down that cflags please. In particulare visibility stuff is *known* broken. I wasn't able to reproduce this problem asking to other users, I'll setup a 32-bit chroot to test them now. Changing severity to major as this version is now stable.
Jabari try to add -fomit-frame pointer and/or move to -O2
just to mention, if you use PIC you should not use mmx. It won't work.
Everyone had trouble with this, try -r4 and see if it works better.
Am I the only one who had to edit the ebuild, removing the has_pic check, to enable mmx support? however, -r4 compiles without problems
Just to make it clear: x86 has just few registers and some general purpose are used for many ABI related stuff, basically if you use -fomit-frame-pointer you free one more, if you use -fPIC you need one more, if you use mmx you need some more (depending on what you are doing I'm afraid). Sometimes the upstream authors take care of that just adding some -DPIC conditional code that fix the problematic part (adding some overhead).
-r4 compiles with no problems here (with the same CFLAGS as before). Thanks very much! A note about -fomit-frame-pointer though: according to the GCC manual for 3.4.3, it's enabled for the following -O levels: "Enabled at levels -O, -O2, -O3, -Os." (See "3.10: Options that control optimization.") so it looks like I (and just about everybody using Gentoo on 3.4.3) has it turned on already. Just an observation... o_-
looks like sometimes I have to review the gcc manpage myself.
About -r4: * the first bad news is that it unconditionaly disable mmx on non-amd64 because of a bash typo. I will attach a patch that fixes it. That means that people who have already tested it should redo their tests, because in its current state it was just like having USE="-mmx". * the good news is that it still compiles fine with mmx support added back and CFLAGS="-march=pentium-m -O2 -fomit-frame-pointer -pipe" * the other bad news is that it then fails again with CFLAGS="-march=i686 -mtune=pentium-m -O2 -pipe" (same error as reported before). Lucas' explanation is right, and I think the gcc manpage is a bit missleading about -O* turning on -fomit-frame-pointer. The point is that it also says: "-O also turns on -fomit-frame-pointer on machines where doing so does not interfere with debugging." Sure, on x86, it does interfere, so no, it is not turned on by default. Maybe an acceptable fix would be an "append-flag" for x86 when mmx is on.
Created attachment 56914 [details, diff] ffmpeg-0.4.9_p20050226-r4--typo.patch Fixes the bash typo in the enable/disable-mmx condition. Also adds "sdl" to IUSE.
Thanks, fixed the typo on CVS. I don't like adding -fomit-frame-pointer to the complete ebuild, as it bails out debug support, so I think it's better to leave it up to users who has problems (and there aren't so much) to fix it.
Created attachment 56918 [details, diff] ffmpeg-0.4.9_p20050226-r4--mmx-ewarns.patch > I don't like adding -fomit-frame-pointer to the complete ebuild, as it bails > out debug support, so I think it's better to leave it up to users who has > problems (and there aren't so much) to fix it. Ok for not forcing -fomit-frame-pointer, but i don't think the average user can guess he should add it to it's CFLAGS to make this ebuild compile. What about something like this patch then? It would: - disable MMX in case of PIC or lack of -fomit-frame-pointer (so that it compiles for everyone) - ewarn the user about why he can't have MMX support (so that he knows what to change if he really wants it)
mmx *is* disabled when pic is enabled. the problem here noted is mainly relative to combinations of cflags which uses the registers in different ways.
> mmx *is* disabled when pic is enabled. Yep, i know. My patch doesn't try to change that behavior, it just adds the ewarn so that user knows that his USE flag can't be honored. And where the behavior changes is only in case fomit-frame-pointer lacks (instead of failing to build, it will do just like for pic: disable mmx and warn the user).
I experienced the same things in comment 28 that TGL experienced; just noticed that MMX wasn't enabled when I had to recompile (for something different). The new -r4 plus -fomit-frame-pointer works for me completely now. Sorry about the misleads; must RTFM harder... ^_^
sorry for insisting on this, but I need some explanations on has_pic. this check is inherited from flag-o-matic.eclass, where I can read: has_pic() { [ "${CFLAGS/-fPIC}" != "${CFLAGS}" ] && return 0 [ "${CFLAGS/-fpic}" != "${CFLAGS}" ] && return 0 [ "$(echo | $(tc-getCC) ${CFLAGS} -E -dM - | grep __PIC__)" ] && return 0 test_version_info pie && return 0 return 1 } If I understand correctly, first two checks in this function return 0 when -fPIC/fpic isn't in $CFLAGS, otherwise the function returns 1. What does [ "$(echo | $(tc-getCC) ${CFLAGS} -E -dM - | grep __PIC__)" ] mean?
ok, I figured that it returns 0 when __PIC__ is in a list of #define. So this function return 0 when a) -fPIC or -fpic is in CFLAGS b) __PIC__ is in a list of #define (I suppose valid for all system) and 1 when both these conditions are false. So has_pic is true (0) when pic is enabled, and false (1) when pic is not enabled, and in this ebuild mmx is enabled when has_pic = 1 ==> ! has_pic = 0. Still I can't understand why in my system mmx is always disabled, but my CFLAGS don't contain -fPIC nor there is __PIC__ in the output of echo etc.etc.
The problem is that 'test_version_info pie' returns 0 on a non pic box, Bug 90391
