SubjectRe: Linux Alpha port: LVM

Are you using a redhat based distro (like suse, mandrake, alpha core or
indeed redhat )?
Are you using stock kernel, libraries and tools or did you haveto build
them yourself ?
Debian comes with LVM1 tools that do not work with 2.6 kernels so I need
to compile them myself or install some ready build binary package for
alpha processor and compatible with the libraries that come with debian3.
What alpha architecture are you running on ?

It may also have something more but it has libdevmapper in it ...
In any case I also tried downloading and compiling
device-mapper.1.00.07.tgz from the link in the LVM2.
It builds and installe fine but I still get compilation errore when I
build LVM2.
Configute is fine, here are a few lines concerning libdevmapper

checking libdevmapper.h usability... yes
checking libdevmapper.h presence... yes
checking for libdevmapper.h... yes

but when I try to compile:

gcc -c -I. -I../include -DLVM1_INTERNAL -DPOOL_INTERNAL
-fPIC -Wall -Wundef -Wshadow -Wcast-align -Wwrite-strings
-Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline
-O2 cache/lvmcache.c -o cache/lvmcache.o

I'm using kernel downloaded from
Here's the relevent section for raid/lvm in config:
# Multi-device support (RAID and LVM)
# CONFIG_MD_RAID10 is not set
# CONFIG_MD_RAID6 is not set
# CONFIG_DM_CRYPT is not set
# CONFIG_DM_MIRROR is not set
# CONFIG_DM_ZERO is not set

Do I need to patch kernel ?
