I managed to compile SANE 0.57 on BL2 but I had to add to all the 
Makefile's on the CFLAGS and CPFLAGS lines (after configuring, or I could 
have done this to Makefile.in first, I think)
-I/usr/src/linux-2.2.16/include

Why was this necessary?  Otherwise the compiler could not find various 
include files.  Is BL2 missing some piece, or might I have deleted 
something I should not have?

I compiled statically so that I will be able to use with BL3 or BL2 (or I 
could have compiled with shared libraries and added to BL3 the BL2 
library).  I now have various libraries in .a instead of in .so.  Does 
this indeed mean I can use the files in BL3 with libc5?

To use SANE I need to ln -s /dev/sg0 /dev/scanner
Or some websites say to use /dev/sga - does it matter which I use?

I picked 0.57 because 0.50 was the first version to support HP scanjet and 
I figured they would have fixed a few bugs before 0.60.  The later sane's 
are enormous.  This was about 250K download and includes xsane and mustek 
and qcam and net and wire, which I do not need.  I will not do a make 
install but copy over only the parts I need.  (Wish me luck).

SW8.1 has a SANE package but it is huge and I am told has many 
dependencies such as libjpeg USB IEEE (parallel scanners), and it supports 
many scanners that I do not have.  I have a scanjet 3p and a 5p (color).
These plug into scsi cards specific to the scanners.

I found an hp and another tutorial that says to add to hp.conf the line: 
scsi HP C2570A 3540 (for the scanjet 3p - each scanner is different)

Modify dll.conf by remarking out all but hp or leave in pnm if you want to 
use GIMP and virtual devices.  (whatever that means).  I will remark out 
the mustek and qcam lines.

As frontend I can then use scanimage, and the manual explains how (for 
once it is very readable).  You can specify -d (or --device) hp:/dev/sg0 
or put the line in /profile to specify the default or hope the software 
guesses correctly. --format pnm (or tiff)  --mode L (or Lineart) 
--filename /tmp/input.ppm .  There are defaults (pnm and gray).

This is a SCSI scanner so I need to load SCSI modules - which ones?
scsi_mod sr_mod and sg?  (I already installed these for my CD burner).
I don't think I need a special kernel (like I did for sound).

And reboot after turning on the scanner because otherwise it will not find 
it.  scanimage -L   lists available devices.  I can put a line in profile 
to specify which device to scan with or let the computer find it if I have 
no other scsi devices set up.

/etc/profile - add
export SANE_DEFAULT_DEVICE /dev/sg0   ??

Will BL2 actually run programs compiled with Redhat 9 or would we need to 
add the later version of glibc2?  Or do some programs work with 2.1.3 and 
some don't, depending on what features they call for?
