[sane-devel] sane frontend questions
I recently got an epson scanner, and I'm trying to get a sane frontend to work with it. I'm running Mandrake 9.0, gcc3.2, and I've installed sane-backends-1.0.12 from the tarball. I had some trouble installing gtk, but I eventually was able to get it to install from the tar file. I've tried both sane-frontends-1.0.11 and iscan-1.5.2 and am getting stuck with both. Any help would be greatly appreciated. When I try to configure sane-frontends-1.0.11 I get the error WARNING: GTK-0.99.13 or newer is needed for compiling the GUI frontends. If you installed gtk as rpm make sure you also installed gtk-devel. ===> GUIs will be deactivated However, I know I have gtk+-2.2.4 because I compiled it from the tarball. When I try iscan-1.5.2, I get errors trying to make the frontends directory. My guess is that these errors have something to do with not finding the esmodule directory. An excerpt of the errors is below. /usr/local/src/iscan/iscan-1.5.2/frontend/pisa_esmod_tool.cc:45: undefined reference to `Focus::operator new(unsigned)' /usr/local/src/iscan/iscan-1.5.2/frontend/pisa_esmod_tool.cc:45: undefined reference to `Focus::Focus[in-charge](tagIMAGE_SETTING*, tagFILTER_SETTING*,unsigned char)' /usr/local/src/iscan/iscan-1.5.2/frontend/pisa_esmod_tool.cc:50: undefined reference to `Focus::ReviseUSM(tagUSM_INFO*)' Does anyone have any suggestions? If you need more information, let me know. Thanks, Andy

I tried what happens when the pipe is closed when threads are used.
It is better to keep the pipe opened :)

When I do not call sanei_scsi_req_flush_all(); when the reader process is killed then sanei_scsi crashes when the main process/thread tries to talk to the scanner the next time. When the process is killed because of sane_cancel or do_cancel is called there is no problem, I can call sanei_scsi_req_flush_all(); in do_cancel. The question is what happens when the SIGKILL was not generated in do_can= cel, e.g. because a user executed a kill command for the reader_process or bec= ause=20 of a malfunction.

I'm using code like this in mustek.c:
if (sanei_thread_is_forked ())
{
DBG (4, "reader_process: using fork ()\n");
close (s->pipe);
s->pipe = -1;
}
else
{
DBG (4, "reader_process: using threads\n");
}
So I think you can't close the pipe in threads.

Try it and you may hang your SCSI system :-) At least if you use multiple SCSI request at the same time a call to sanei_scsi_req_flush_all() is necessary. Bu you can do that from the main process, too. Bye, Henning

[sane-devel] sanei_thread: pthread test on linux possible?
Hello Henning > ./configure --enable-fork-process=3Dno I already found it out :). In the umax backend (forked reader process) I used a signal handler that catches sigkill and calls=20 sanei_scsi_req_flush_all(); when the reader_process is killed. I am not sure if this is necessary but I think I did not add this just because of fun. Any ideas?

Hello.
I would like to do some tests with sanei_thread.
Is it possible to actiavte the pthread based code on linux?
In aclocal.m4 it looks like it is only enabled for MacOS X:
case "${host_os}" in
darwin*) # currently only enabled on MacOS X
use_pthread=3Dyes

use_pthread=3Dno

[sane-devel] vendor linux drivers for Epson scanners
Hello! Maybe all of you know, but for me this is very new. I have called Epson and asked them about Linux support for the Stylus RX 500 and they told me that THEY provide Linux drivers for several printers and scanners, too. Unfortunately, currently not for the RX500. So, maybe some of you would like to check this out: http://www.epkowa.co.jp/english/linux_e/index.html And they license it under LGPL and GPL ! So, you could use it for SANE, can't you? Have fun! I will check the scanner drivers for the 2400 tonight... Bye, Steffen

We don't have any information about this scanner, otherwise it would be listed in our lists.

(please note that I'm not a > C/C++ programmer) Have a look at this page: http://www.sane-project.org/contrib.html and report all the details you can find to us. Maybe it's possible to find out the chipset used that way. If there is no backend yet for that chipset you'll have to acquire some C knowledge and write a backend (or hope that someone else does that). Bye, Henning

Hi, 1. Is there any usbsnoopy log published on-line in the Internet for the HP3670 and/or HP2400 models? 2. Preview scan will be enough for a initial analysis. Does the scanner work after the preview scan then using usbsnoopy? 3. You said you dont' receive anything in the log, but does the scanning software reveice any image? 4. Does the scanner head move?

[sane-devel] problem connecting to saned over network
Hello, the problem with "Address already in use" is probably caused by an incorrect shell script. You cannot give option -d to saned in such a script but have to execute saned without parameters. On http://penguin-breeder.org/sane/saned/ an example is given. The other problem you've stated is that you cannot connect to saned when it is operated by xinetd. Do you mean that you cannot connect to it, not even with telnet, or that xsane (for example) doesn't list any scanner? I guess it's the later case. You're probably running saned as user "sane" from xinetd. Please make sure that user "sane" has appropriate access rights to your USB/SCSI/parport/whatever devices. regards -- jochen

Hi, I tried contacting HP too. Had met Bdale garbee at Linux Bangalore meet. he said he would try to see if he could help. will send him one more e-mail and see if it works. also tried contacting one of the R &D people.

Dear All, I'm new to Sane, so please forgive me if I'm asking one of those anoying questions... I just received a HP Scanjet 3690 scanner. It is a cheap but nice one: it has also support for slides/films. My Suse 9.0 was not able to recognize my scanner and in the sane supported devices I didn't find any mention of it. I also googled a bit but I didn'd find any notes on having my scanner working under linux... is it possible to make it work? If so, can you give me some advice? If it is not yet upported is there anything I can do to analize it and (with your help) create a specific configuration for it?

[sane-devel] problem connecting to saned over network
Trying to connect to saned from remote computer on local network. If I start saned manually with the debug option (-d128), I can connect fine via telnet and even use xsane. When I add the proper line to xinetd.conf, I can not connect. I've made the shell script to allow debug mode w/xinetd and output an error file. I have no lines that would block me in hosts.allow/hosts.deny (do they even have any effect when using xinetd?) and I'm not using tcp_wrapper. Not going through a firewall.
