[Qemu-devel] qemu-system-ppc on a pc

[marco]

Hello,

I'm trying to run linux-ppc on an x86 pc host (Gentoo). I downloaded the 
disk image and kernel from freeoszoo and, when trying to run it, I get:

pink qemu # qemu-system-ppc -prep -localtime -kernel ./zImage.prep ./linux-ppc.img
*** ERROR: opcode 57 already assigned in opcode table 80
*** ERROR: unable to insert opcode [00-80-57]
*** ERROR initializing PPC instruction 0x00 0x80 0x57
invalid/unsupported opcode: 12 - 02 - 18 (4bfffe05) 0xfffffffc 0
Segmentation fault


and it doesn't even come up ...
Qemu has been compiled with gcc 3.4.3 and binutils 2.15.92.0.2.

Any hints, suggestions?
Let me know if more info is needed.

Thanks,
marco

Seems to me that you don't use qemu from CVS, but 0.6.1, am I right ?
Qemu PPC has long been broken when compiled with gcc 3.4.x.
Then, it seems you have two solutions:
- use gcc 3.3.x
- or use current qemu CVS repository.

You are right, I'm using 0.6.1 from gentoo's packages. I'll try the CVS 
version ... Thank you!
