[sane-devel] About the configure.in
Dear allan Thank you for your help, I reply late feel shy. 1.It must be --disable-shared When I recompiled the backend, otherwise, there will be compile errors. ~ $B-!(BCFLAGS=-g -Wall ./configure --prefix=/usr --sysconfdir=/etc --libdir=/usr/lib BACKENDS=ricoh $B-(Bmake ... undefined reference to 'sanei_tcp_open' ... undefined reference to 'sanei_tcp_write' ... undefined reference to 'sanei_tcp_read' $B,(BI have been include the head file, #include sane/sanei_tcp.h or #include ./include/sane/sanei_tcp.h but can not fix the error if not the --disable-shared Thanks Very Much,Best Regard Yours Sincerely, 1. you did not tell me the link error, so I cannot tell you how to fix! 2. Different linux distributions put libraries in different places. You want something like ./configure --prefix=/usr --sysconfdir=/etc but you might have to add something like --libdir=/usr/lib64, if that is where your distribution put the existing copy of libsane.so allan On Wed, Nov 20, 2013 at 5:43 AM, YiHao at rst.ricoh.com wrote: Dear allan: Thanks a lot for your help, I have some other question about sane to trouble you: $B-!(BIt must be --disable-shared When I recompiled the backend, otherwise, there will be link-errors.

Dear allan: Thanks for your help, I still can't get the debug log by using the following, LD_LIBRARY_PATH=/usr/local/libSANE_DEBUG_RICOH=255 xsane ==? LD_LIBRARY_PATH=/usr/local/lib/sane SANE_DEBUG_RICOH=255 xsane == ? I would like to ask whether there are other LD_LIBRARY_PATH needs to be set. Best Regard Yours Sincerely, Yihao m. allan noah kitno455 at gmail.com wrote on 11/05/2013 09:45:32 PM: You are running a recompiled version of scanimage, which searches /usr/local for libraries. Your system provided xsane does not do this. Try telling the linker where to look like so: LD_LIBRARY_PATH=/usr/local/lib SANE_DEBUG_RICOH=255 xsane If this works, you can make it permanent by adding /usr/local/lib to /etc/ld.so.conf, and running ldconfig allan On Tue, Nov 5, 2013 at 5:21 AM, YiHao at rst.ricoh.com wrote: Hello allan, I can get debug log with scanimage, Thanks a lot !

I don't think you want to use --disable-shared. You should build and install shared libraries someplace that your system's linker will find them. 2. You get debug logging by using environment variables with any sane frontend, like so: SANE_DEBUG_RICOH=255 scanimage -L 3. You do not see any scanners listed by scanimage -L because the sane-backend only supports a few older ricoh scanners. I doubt your scanner is supported. Three different backends provide this support.

Best Regard Yours Sincerely, Yihao We have a debugging library which is part of sane-backends. It allows you to set an environment variable, and which causes the backend to print messages to STDERR. If your backend is part of sane-backends, you can use this library. If you backend is outside of sane-backends, you can certainly setup something similar in your backend. You should not have to recompile the frontend. allan On Thu, Aug 22, 2013 at 6:46 AM, YiHao at rst.ricoh.comwrote: Dear Sir or Madam: I want to know, How can I debug the sane-backend by frontend(e.g. scanimage), How to enter the backend's breakpoint, Do I need to compile the frontend if I want to know whether the backend receives the Frontend command.

[sane-devel] Get the devices about sane
Dear allan: I am sorry to trouble you again, I can use the sane backend by following methods, SANE_DEBUG_RICOH=255 scanimage --format=tiff out1.tiff but if no environment variables SANE_DEBUG_RICOH=255, sane will not be able to work = scanimage: no SANE devices found. Excuse me, Is this what I need to do? Look forward to your help, Thank you~ Best Regard Yours Sincerely, Yihao
