dm-crypt

[rinonapo]

I configured my 2.6.12.3 kernel for dm-crypt... everything works then I compile the user-space tool cryptsetup-luks from
http://luks.endorphin.org/dm-crypt
but on make it spits

keyencryption.c:31:26: libdevmapper.h: No such file or directory
keyencryption.c:35:26: libdevmapper.h: No such file or directory
keyencryption.c: In function `LUKS_endec_template':
keyencryption.c:100: warning: initialization makes pointer from integer withouta cast
make[2]: *** [libluks_la-keyencryption.lo] Error 1
make[2]: Leaving directory `/home/bastille/cryptsetup-luks-1.0.1/luks'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/bastille/cryptsetup-luks-1.0.1'
make: *** [all] Error 2

I tried using the cryptsetup-1.0.1-i686-pc-linux-gnu-static.bz2 - Precompiled binary version 1.0.1: my kernel is working correctly so I issue the commands written on the luks page

http://luks.endorphin.org/dm-crypt

# cryptsetup luksFormat /dev/loop0

WARNING!
========
This will overwrite data on /dev/loop0 irrevocably.

Are you sure? (Type uppercase yes): YES
Enter LUKS passphrase:
failed to setup dm-crypt mapping.
failed to write to key storage.
Command failed.


What's wrong???
