[Qemu-devel] powerpc (debian/sid) woes

[Christof Petig <christof@petig-baender.de>]

Hi,

Since 0.1.6 I encountered occasional compile/link failures and various 
errors on powerpc. Since I thought them to be temporary I did not spend 
much thought about it and waited for a new (and working version). But 
looking more closely these problems seem to persist ...

Intermediate problems:
since 2003-5-27 18:50:  dyngen: could not find .sdata section

but since 2003-5-30 18:50 (and up to current CVS):
The process loops forever (gcc-3.3,-O2) or encounters an illegal 
instruction (gcc-3.3, -O0).

Since debian shipped more actual kernel headers with glibc, I am no more 
able to try gcc-2.95 (gcc-3.2 fails like gcc-3.3):

syscall.c: In function `_llseek':
syscall.c:95: more than 10 operands in `asm'

(looks nonsense to me)

But in any case I would like to have 3.3 working.

Offending code attached.

But what is even nagging me more is the fact that I don't have a working 
newer wine than the one you offer for download. I tried to download 
.debs from unstable, as of 2003-4-11 it's ls worked. Since 0.1.6 it 
segfaults.

Has anybody had any recent success with powerpc, a recent wine, a recent 
compiler and a recent glibc? ;-)
