Description:   Opened: 2006-12-30 10:45 0000 
xvid configure script prefer to use yasm than nasm.
if yasm and nasm installed on system, configure select yasm.

apply xvid-1.1.0-noexec-stack.patch spawn failur compiling at asm code on x86
system at least for x86 (i686-pc-linux-gnu).
becaue this patch include incompatible with yasm on x86 code.

In contrast, build succeed while taking off this patch.

oops, i confirmed success compiling with yasm-0.5.0_rc1.
is there something wrong in yasm or does yasm get newer incompatibly?

it also occured in libsdl.

amd64 and/or Kugelfang, could you please take a look too at this problem?

This still applies to xvid 1.1.2 and is due to the execstack patch.
Is that a regression in yasm or is the patch using a deprecated syntax ?

------- Comment #5 From SpanKY 2007-01-26 08:14:11 0000 ------- 
if you quote the section name, it should work in both nasm and yasm

 %ifidn __OUTPUT_FORMAT__,elf
-section .note.GNU-stack noalloc noexec nowrite progbits
+section ".note.GNU-stack" noalloc noexec nowrite progbits
 %endif

the latest version of yasm in svn doesnt suck and supports section names like
this without quotes, but that isnt released so just quote it for now

------- Comment #6 From Alexis Ballier 2007-01-26 10:37:49 0000 ------- 
Thanks for the heads up.

vapier (and/or others) : could you please update the patch then for xvid-1.1.2
(adding a new bziped patch named with -1.1.2 replacing the current one should
avoid md5 problems).
yasm 0.5.0 is in ~arch so leaving 1.1.0-r3 as is shouldn't be a problem for
now.

I'd have done this myself but I'm at work right now and I'll be away for the
week end. I'll do it on monday if this is not fixed yet at that time.

------- Comment #7 From SpanKY 2007-01-26 11:08:57 0000 ------- 
erm, i dont see what yasm status has to do with this ... no yasm release has
ever support non-ascii chars in section names without quoting

so we need to update all xvid ebuilds as this failure should [in theory] happen
whenever user has yasm installed on x86

------- Comment #8 From SpanKY 2007-01-27 11:09:31 0000 ------- 
ive fixed 1.1.0-r3 and 1.1.2 since that covers the latest amd64/x86
stable/unstable
