Description:   Opened: 2004-02-09 06:29 0000 
This is what I get from mythtv-.14 and .14-r1 . I have tried to lower myflags
wich by default isn't aggresive. I use 


CFLAGS="-O2 -march=athlon -pipe -fomit-frame-pointer"

------- Comment #6 From Max Kalika (RETIRED) 2004-02-09 13:14:24 0000 ------- 
which linux-headers do you have installed?

------- Comment #7 From Snappi 2004-02-09 13:19:25 0000 ------- 
currently I have linux-headers-2.4.22, and that's strange because I use
kernel-2.6.2. I will update and reply with the results.

------- Comment #8 From Snappi 2004-02-09 14:37:40 0000 ------- 
I have now upgraded linux-headers to 2.6.0 and re-emerged glibc and I still
have the same problem.

------- Comment #9 From Christian Kruft 2004-02-27 14:24:42 0000 ------- 
hey, i had the same problem with my cflags - so i tried CFLAGS=""
ACCEPT_KEYWORDS="~x86" emerge mythtv -  so mythtv 0.14 compiled.

------- Comment #10 From brian tarricone 2004-03-03 00:39:42 0000 ------- 
fails for me as well.

> add mmx to your USE flags
> add -mmmx to your CFLAGS

not sure how either of these would help...  assuming you're using a -march= that supports MMX, gcc should enable MMX automatically.  (either way, i tried it with "-mmmx" added, and it still failed.)

if, by chance, you meant doing USE="-mmx", that won't do anything, since the ebuild doesn't honor the mmx USE flag.

i tried adding "-mno-mmx" to my CFLAGS, and that allowed the compile to finish sucessfully (though there was a strangely long pause while compiling the file in question).  however, i don't consider that a solution, since my machine is a bit on the edge where required performance is concerned, and i'm not so sure it's going to run so well MMX-less.

------- Comment #11 From Christoph Richter 2004-03-04 13:55:34 0000 ------- 
I have had the same error using gcc-3.3.3 with CFLAGS="-march=athlon-mp -O3
-pipe -fomit-frame-pointer -mmmx -m3dnow -msse -mfpmath=sse,387 -ffast-math
-frename-registers -fsched-spec-load -fforce-addr -fprefetch-loop-arrays
-ftracer" 

However the responsible CFLAG seems to be -fforce-addr, without it mythtv-0.14
compiled just fine. Maybe your version of GCC enables that option at -O3??
Which version do you use, Snappi?

------- Comment #12 From Snappi 2004-03-10 05:33:16 0000 ------- 
I got mad en did a clean install and everything worked fine after that.

------- Comment #13 From Max Kalika (RETIRED) 2004-03-10 10:27:16 0000 ------- 
Perhaps kernel headers where somehow corrupted?  Can we close this now?

------- Comment #14 From brian tarricone 2004-03-10 10:36:30 0000 ------- 
confirmed: removing -fforce-addr from CFLAGS allows compilation to succeed. 
perhaps a 'filter-flags' statement should be added to the ebuild?

------- Comment #15 From Max Kalika (RETIRED) 2004-03-10 10:43:33 0000 ------- 
I'm really hesitant to start adding filter flags for all the possible things
that can break it.  Lets just close this one as one of those "overly-optimized
CFLAGS" issues and refer people here if they hit it.

------- Comment #16 From Max Kalika (RETIRED) 2004-03-10 10:56:20 0000 ------- 
nevermind, I added this to filter-flags.

------- Comment #17 From Greisberger Christophe 2004-06-06 13:26:41 0000 ------- 
Well, there are other flags that make the emerge fail...
I'm currently searching which one(s).
With CFLAGS="" it works, but with my current flags it fails (see emerge info).
I'm emerging, adding one by one my flags and I'll post the result later.

Found it! Of course it was the last one...
The compilation fails with -momit-leaf-frame-pointer
