Using a new backend with an old sane

Hi every one,

I'm asking a question for someone else who owns a HP scanjet 4400C.

The backend rts8891 is very recent and isn't included in any version of
our linux distribution (Mandriva).

In the FAQ, I see it's possible to compile only one backend :
http://www.xs4all.nl/~ljm/SANE-faq.html#44

But is it possible to use it with an older version of sane (1.0.19) ?
Maybe copying the involved files under /usr/lib/sane where the other
backends are ?

In my distribution, I see there is also a bunch of files
under /etc/sane.d. Maybe there's one file to put there ?

Thanks for your help. I hope my idea isn't too crazy ^^

it should work. you will just have to make sure to:

1. give the correct arguments to configure
2. setup the correct symlinks in /usr/lib/sane
3. copy the config file to /etc/sane.d
4. add the name of the backend to /etc/sane.d/dll.conf

But honestly, it might be easier to rebuild the entire sane-backends
package. BTW- sane 1.0.20 is more than 4 months old, what is your
distro waiting for? :)

Thanks for the recipe :-)
Now, I only need to translate it in a recipe with 20 000 steps -_-

Indeed, the scanner is owned by a linux newbie. He has just installed
Mandriva for the first time and he's asking for help on another mailing
list...

Well, I'm surprised that sane 1.0.20 isn't available, even in the devel
version of the distro.... Oh wait, I see that the last iteration of
sane-bakends-1.0.19 contains a file "hp_rts88xx.conf". Since I have
searched rts8891, I hadn't seen it the first time.

I will go ask to packagers if it's the good one. Maybe they add new
backends to sane 1.0.19.

        Hello,
       
        there is no hp_rts88xx.conf in unpatched SANE sources. But there is an
external backend with this name that can only do 300/600 dpi gray scans:
http://hp44x0backend.sourceforge.net/

Regards,
        Stef

Though, there is this backend on the SANE website :
http://www.sane-project.org/sane-backends.html#S-RTS8891

You mean it isn't included yet in SANE 1.0.20 ?

        Hello,

        I meant that there was an external backend which has been superseded by the
rts8891 backend. The rts8891 backend is part of SANE 1.0.20. What I found
intriguing is that you have some conf file coming from this external backend
laying around.

Regards,
        Stef

Oh ! OK, I understand.

Maybe packagers of my distro have patched SANE with this external
backend... I don't know.

I just wanted to add : it worked like a charm !

The "old" sane 1.0.19 use now the new backend through symbolic links
and "my" newbie is happy :-) (and me too, of course ^^)
