Hi gentlemen!

I am trying to set up xenomai along the
http://www.xenomai.org/index.php/Xenomai_quick_build_quide
using exactly the same packages as described (2.6.25.11 linux and 2.4.4
xenomai)

.. but failed so far :-(

I did all the following as superuser:

cd /usr/src
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.25.11.tar.bz2
wget http://download.gna.org/xenomai/stable/xenomai-2.4.4.tar.bz2
tar xfj xenomai-2.4.4.tar.bz2
tar xfj linux-2.6.25.11.tar.bz2
cd /usr/src/xenomai-2.4.4
scripts/prepare-kernel.sh
            keyed in: /usr/src/linux-2.6.25.11
cd /usr/src/linux-2.6.25.11
cp /boot/config-2.6.24-16-generic  .config
make menuconfig

When calling make menuconfig I see the following in the "Real-time
sub-system" menu


*** WARNING! You enabled APM, CPU Frequency scaling or ACPI 'processor'
*** option. These options are known to cause troubles with Xenomai.
*** NOTE: Xenomai conflicts with PC speaker support.
*** (menu Device Drivers/Input device support/Miscellaneous devices)
*** NOTE: Xenomai needs either X86_LOCAL_APIC enabled or HPET_TIMER
disabled.
*** (menu Processor type and features)

The section in .config looks like this:

#
# Real-time sub-system
#

#
# WARNING! You enabled APM, CPU Frequency scaling or ACPI 'processor'
#

#
# option. These options are known to cause troubles with Xenomai.

#

#
# NOTE: Xenomai needs either X86_LOCAL_APIC enabled or HPET_TIMER disabled.
#

#

#
CONFIG_XENO_GENERIC_STACKPOOL=y


Shouldn't there be all the xenomai specific settings there?
What went wrong?
How do they usually come into the .config file?


Thanx

In your report I read:
Xenomai conflicts with PC speaker support.
(menu Device Drivers/Input device support/Miscellaneous devices)
Xenomai needs either X86_LOCAL_APIC enabled or HPET_TIMER
disabled.(menu Processor type and features)

So, what do you think ?
