Building and Installing SANE on HP-UX
|
|
-------------------------------------
|
|
|
|
This file contains some notes on building and installing SANE on
|
|
HP-UX. It tells you which compiler switches to use, how to find out
|
|
to which controller card your scanner is connected, and how to create
|
|
a device file for it.
|
|
|
|
Building SANE
|
|
-------------
|
|
|
|
On HP-UX, SANE can be built using either the HP ANSI C compiler or
|
|
GCC. For GCC, no special arguments to configure are necessary. For
|
|
the HP compiler, invoke configure like this:
|
|
|
|
CC=cc CFLAGS="-Ae -O" ./configure
|
|
|
|
Higher optimization levels than -O (equivalent to +O2) may fail
|
|
to compile correctly.
|
|
|
|
If you're using the HP compiler on 64-bit HP-UX 11, you must build
|
|
64-bit executables:
|
|
|
|
CC=cc CFLAGS="-Ae +DA2.0W -O" ./configure
|
|
|
|
|
|
|
|
Some of the make files use GNU extensions, so you have to use gmake
|
|
(GNU make). Gmake binaries are available from the HP-UX Porting and
|
|
Archive Centre <http://hpux.connect.org.uk> and its mirror sites.
|
|
|
|
Installing SANE
|
|
---------------
|
|
|
|
The SCSI pass-through driver (sctl) must be enabled in your kernel,
|
|
but it is by default.
|
|
|
|
Naturally, the scanner must have a non-conflicting SCSI address and it
|
|
must be connected to the right SCSI bus to work.
|
|
|
|
You'll probably need to create a device file for your scanner. To do
|
|
this, you'll need to know its SCSI address, and, if your machine has
|
|
multiple SCSI controllers, the number of the one it's connected to.
|
|
As root, you can use ioscan -f to find this information.
|
|
|
|
For example, here's the partial ioscan output for a C200:
|
|
|
|

|

|
|

|
|
|
|
You can see that there are two SCSI controllers, Ultra Wide SCSI and
|
|
Built-in SCSI (narrow single-ended). The I column shows the number of
|
|
the controller card. Our scanner, an Epson Perfection 1640, is
|
|
connected to controller 1, and has SCSI address 1 (that's the 1 in the
|
|
H/W Path number).
|
|
|
|
You can now create the device file using mknod(1M). In this example,
|
|
the command would be:
|
|
|
|
mknod /dev/rscsi/c1t1d0 c 203 0x011000
|
|
|
|
In the filename, c1 specifies controller 1, t1 is target 1 (i.e., the
|
|
SCSI address), d0 (device 0) because it's the only device at that
|
|
address. 203 is the major number of the sctl driver. In the minor
|
|
number (0x011000), 01 again means controller 1, and the second one
|
|
means SCSI address 1. See scsi_ctl(7) for details.
|
|
|
|
For ease of use with SANE, I'd recommend to create a link to
|
|
/dev/scanner, e.g.,
|
|
|
|
ln -s /dev/rscsi/c1t1d0 /dev/scanner
|
|
|
|
To allow normal users to access the scanner, the best approach is
|
|
probably to create a new group, say, "scanner", and make the scanner
|
|
device file readable and writable for the group, e.g.,
|
|
|
|
chown bin:scanner /dev/rscsi/c1t1d0
|
|
chmod g+rw /dev/rscsi/c1t1d0
|
|
|
|
You would then add all users that are allowed to use the scanner to
|
|
that group. If you haven't already done so, you should do
|
|
|
|
ln -s /etc/group /etc/logingroup
|
|
|
|
so that users are automatically in all groups to which they belong
|
|
(and don't have to use newgrp(1)).
