Compile problem - Linux 2.6.1 + LVM2.2.00.08

Hi there

I Cannot compile LVM2.2.00.08 on a system with the following info. Compilation error output included too.
Help would be appreciated - this is my first attempt to
run a system with LVM and thought it best to get going with the latest stable kernel and LVM to prevent migration headaches at a later stage. Thanks.

Slackware 9.1

/ and /boot on ext3 paritions and swap separate would like to use remaining disk space with LVM

kernel-headers-2.4.22-i386-1
gcc-3.2.3-i486-2
gcc-g++-3.2.3-i486-1

Successfully built and running Linux 2.6.1 with:

#
# Multi-device support (RAID and LVM)
#
CONFIG_MD=y
# CONFIG_BLK_DEV_MD is not set
CONFIG_BLK_DEV_DM=y
CONFIG_DM_IOCTL_V4=y

cd /usr/src/build/LVM2.2.00.08
./configure --enable-readline --with-lvm1=none

resulted in compilation failure... see below:

Let me know if more details are required to track my issues down.

compile and install device mapper first

Tried that earlier and it failed too - after reading the docs, wasn't certain if I had to do this, since 2.6.x has device-mapper in the kernel....

Anyway, everything succeeded now - the problem was with my kernel-headers. I'd been a twit and symlinked /usr/include/linux to /usr/src/linux-2.6.1/usr/include/linux and found Linus' post regarding this, before rectifying my mistake:

http://www.ussg.iu.edu/hypermail/linux/kernel/0007.3/0587.html

So I removed my symlink madness and re-installed the original kernel-headers package as per my original post and then successfully installed both device-mapper and LVM!

Thanks
