[sane-devel] Scanner Question
Hi, I need an advice - if possible, please. I have to scann 15000 35mm frames and 350 slides. I wish to purchase a NIKON scanner which will be connected via USB and will work on Linux "hopefully" Here couple of models available: - Nikon Super Coolscan 5000 ED series - Nikon Coolscan V ED How can I find out in depth which of the current models in the European market are compatible or could be compatible? My OS is Gentoo Linux. Also, I heard that there is a software that runs under Linux and supports all kind of scanners. Please provide me with some guidance so that I can make a good choice; considering the cost of it. Thank you, Spiro

[sane-devel] Undefined symbols
Hi All,
I don't know whether this is the correct mailing list or not, but
thought the developers here would be able to help me out with the
small thing that I am missing.
I am trying to write a dynamic library (.so) which contains my SANE
code and my application would do a dlopen() into this library.
However, I get undefined symbols for all my SANE type members of the
class CSane. For eg.
I have=20
class CSane
{
public:
static SANE_Handle handle;
}
When I dlopen() into this code, I get an error as undefined symbol
CSane::handle.
The way i make my .so is:
gcc -shared -o libXYZSane.so a.o b.o c.o -lsane
Any help in this regard would be helpful. Also if you feel you are
aware of a proper alias which would be able to address the issue, feel
free to forward this mail.
Thanks,
Mohit
[sane-devel] scanimage looks for the wrong libs
Hi :) I'm in the process of making a sane-backends port to OpenBSD. So far, I encountered only one problem. When starting scanimage with DEBUG, I can see that it is looking for *.so.1.15 libs (ie : libsane-epson.so.1.15). The thing is, this lib does not exist, but *.so.1 (ie : libsane-epson.so.1) exists. I can rename/symlink those libs so they end with 1 instead of 1.15 and it works, but it's not a great solution. How can I either make scanimage look for the right libs or make libtool (or other) install the libs with the correct name ? Thanks in advance. Regards, Antoine ps : exemple for the problem --> $ SANE_DEBUG_DLL=5 scanimage -L ... bla bla... [dll] load: searching backend `agfafocus' in `/usr/local/lib/sane' [dll] load: trying to load `/usr/local/lib/sane/libsane-agfafocus.so.1' [dll] load: couldn't open `/usr/local/lib/sane/libsane-agfafocus.so.1' (No such file or directory) [dll] load: couldn't find backend `agfafocus' (No such file or directory) ...bla bla... $ ls /usr/local/lib/sane/libsane-agfafocus.so* /usr/local/lib/sane/libsane-agfafocus.so.1.15

Hi Brad, I asked the same question a week ago (as someone pointed out). Here's a recap of what I found out based on that and my own testing: 1. HP 74XX: works, but the scanner goes to sleep after 15 minutes and won't wake up without power cycle. Also the feed mechanism tends to skew pages slightly. 2. HP 55XX: others say don't use these as they are broken in various ways. 3. HP 82XX: apparently not well supported by driver. Note that HP doesn't make the 82XX or 74XX scanners, they use the Avision backend. 4. Brother MFC: one person reported that one of these worked well for him (I forget which one, but it was an inkjet). However, a lot of people say the Brother devices are junk. Plus buying a multifunction device just for scanning seems lame. I have a perfectly good laser printer in my office and I don't need to replace it. 5. Some sort of Fujitsu: it seems like Fujitsu might make some scanners with good ADF support. See the previous thread for specific models. These generally seem to be just ADF units, not flatbeds. I saw a couple on ebay for around $350. Basically I have yet to find a good ADF scanner for my office. I bought an HP 7450 on ebay for $100 and that would work ok if it didn't have the wakeup problem. I'm thinking of buying a used Fujitsu on ebay also for around $300-$400. The Avision backed developer has indicated that the problem with the 7450 should be fixable in the backend. There seems to be a big cliff with these devices: you can get various mediocre to downright unusable scanners with ADFs for around $100-$500 new and used. Or, you can get one that might really work for $2000-$3000. For example, Canon and Fujitsu both have professional-looking ADF scanners in that price range. I also have a standalone Canon PC-1060 copier in my office. It's clearly a scanner + a laser printer because it can scan pages into a buffer and then print them out (i.e. the scan and the print aren't directly connected). It works great and has a very reliable ADF. I'm not sure how much it originally cost but I believe it was in the $1000-$2000 range. There's even a cutout on the back of this scanner that looks like it would hold a network card. I called Canon and they told me no such network connection exists for that scanner. If it did, that would be a great solution. I've got a Ricoh salesman coming to my office tomorrow to see if they can sell me a networked scanner. It's my fear that anything like that will require Windows, though. Anyway, that's my long-winded take on all this. I'm actually trying to put together a complete network scan + fax solution for my office using a SANE scanner and Hylafax. P.

Thanks for that info, btw. I find myself discouraged. :/ Seemingly the best solution is an evil Brother MFC? Does anyone have any other solutions? If it's a MFC, I'm quite willing to go with laser, in fact.. I'd prefer it.
