Thanks, that was the hint I needed! It works when I do
"xscanimage hp:/dev/scsi/sc1d5l0". Cool...

I found the problem with find-scanner.c -- change

#if defined(__sgi__)
to
#if defined(__sgi)

But when I start xscanimage with no args, it still says "no devices."
How do I set that as the default?

I got it to print an error message once:

** WARNING **: file gtkwidget.c: line 2641: "widget != NULL"

and to dump core once:

** ERROR **: sigsegv caught

but now I can reproduce it...

Is it only possible to save pnm files? No jpeg or tiff encoder?

Is there any way to have it show you the full-sized image as it is
being scanned? (That is, write it to the screen and the file at the
same time?)

I found the gcc/ld problem too -- if I set $LD to /usr/lib/old_ld
before configuring, it works. (Apparently you need to use old_ld
to do dynamic linking with gcc on SGIs.)

But, after doing that, I had to edit "libtool" by hand to make it
use

LD="/usr/lib/old_ld"

instead of

LD="/usr/lib/old_ld -n32"
