[Xenomai-help] help with xenomai-2.5.0 on pure64bit linux x86_64

[lux-integ <lux-integ@domain.hid>]

Greetings

 I am new to xenomai and I am attempting to   install    a RT-kernel on a pure 
64-bit  (not multilib) amd64 linux setup.  The machine has a Sempron CPU and 
2 GBytes of RAM.  The distribution is cross-lfs  compiled from sources.  This 
is what I have done:-

a) I   fetched fresh kernel2.6.32.2  source-code   and placed it 
in /usr/src/linux like so:-
`linux' -> `linux-2.6.32.2'

b) ..I then  applied  the  xenomai patch as such:-
$SOURCES/xenomai-2.5.0/scripts/prepare-kernel.sh --linux=/usr/src/linux  --adeos=$SOURCES/xenomai-2.5.0/ksrc/arch/x86/patches/adeos-ipipe-2.6.32.2-x86-2.5-00.patch  --arch=x86_64

c) I configured the kernel using make menuconfig  disabling smp support  (here 
is the relevent section of my kernel configuration):-
# CONFIG_X86_DS is not set
CONFIG_HPET_TIMER=y
CONFIG_HPET_EMULATE_RTC=y
CONFIG_DMI=y
CONFIG_GART_IOMMU=y
CONFIG_CALGARY_IOMMU=y
CONFIG_CALGARY_IOMMU_ENABLED_BY_DEFAULT=y
CONFIG_AMD_IOMMU=y
CONFIG_AMD_IOMMU_STATS=y
CONFIG_SWIOTLB=y
CONFIG_IOMMU_HELPER=y
CONFIG_IOMMU_API=y
CONFIG_NR_CPUS=1


d) but when I type make  I encountered a failure  like so:-

help would be appreciated
