[linux-lvm] Problems compiling Kernel 2.4.3+lvm-0.91beta7

[Paulo Fessel]

Hello, people at linux-lvm.

I'm not getting to compile Linux Kernel 2.4.3 together with lvm 0.91 beta7.
Here are the warning and error messages I get:

These problems don't happen at all when I compile lvm-0.91beta6. But I need
beta 7 because with beta 6 I'm not being able to remove a deactivated
logical volume:

[root at softmachine linux]# lvremove /dev/datavg/datalv
lvm -- Module successfully initialized
lvremove -- can't remove logical volume in inactive volume group "datavg"

[root at softmachine linux]# lvremove -f /dev/datavg/datalv
lvremove -- can't remove logical volume in inactive volume group "datavg"

[root at softmachine linux]#

There are no messages in /var/log/kernel/*.

I'm running Mandrake Linux 7.2 with pristine 2.4.3+ext2resize+lvm-0.91beta7.
The errors occur regardless of application of ext2resize or not.

What could be wrong?

TIA,
