Hi Stefan,

my distro doesn't seem to have this package:
debian:/home/erik# apt-get install acpica-tools
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package acpica-tools
debian:/home/erik#

The IASL compiler is installed, here the version:
Intel ACPI Component Architecture
ASL Optimizing Compiler version 20060912 [Dec 20 2006]
Copyright (C) 2000 - 2006 Intel Corporation
Supports ACPI Specification Revision 3.0a

And there is no newer version available for my distro.

It's getting more and more complex to build qemu, is there a reason why everyone
needs to build the acpi stuff by himself? It should be something static like the
bios binary files, right? (Sorry for this question, I'm not familiar with ACPI)
So you could provide the defaults directly and everyone that wants to modify the
defaults is free to compile it by himself.

And if these tools are required, please add an error message at configure
runtime so that the successive errors at runtime will not appear, because
compiling is then blocked by configure. And if the IASL is too old, a version
check at configure runtime would be helpful as well.

Thanks.

Best regards,

Erik
