Julien,

Seeing your mail, I too tried to compile Sane under Suse 10.2 -- and
got the same error message. HZ should be defined somewhere in the
"kernel-related" header files, and theoretically the right header
file should be included in sg.h , because HZ is used there too.

You can fix the error by adding the line

#include <linux/compiler.h>

to sanei/sanei_scsi.c, near line 89:

#if defined (HAVE_SCSI_SG_H)
# define USE LINUX_INTERFACE
#include <linux/compiler.h>
# include <scsi/sg.h>
#elif defined (HAVE__USR_SRC_LINUX_INCLUDE_SCSI_SG_H)
# define USE LINUX_INTERFACE
#include <linux/compiler.h>
# include "/usr/src/linux/include/scsi/sg.h"

(better add the line two times, as shown: I don't know, which
variant will be used on your system).

Out of curiosity, I compiled sane-backends 1.0.18 on Ubuntu 6.10 --
no problems there.

Suse 10.2 uses a slightly newer kernel version (2.6.18) than Ubuntu
6.10 (2.6.17). Does anybody know, if "something serious" changed in
the "kernel related" header files between these versions? Or is this
a problem specific for Suse 10.2?
