Now, here is some useful information. > /usr/lib/libesint43.so: undefined symbol: __gxx_personality_v0 > May this line explain why I can not use scanimage > -depkowa:libusb:004:005 or xscanimage? Yes, it does. It indicates a dependency problem with the standard C++ libraries that libesint43.so needs and the ones that are installed on your system. The odd things is though, that you report that you can use your scanner when using iscan ... Hmm, iscan itself is written in C++ (nominally at least) so it probably loads the required library in time for libesint43.so (which is loaded dynamically) to use. When you use scanimage (written in pure C), this does not happen so ... I guess we need to review how our libesint*s get build and make them take care of loading the libraries they require on their own so that the epkowa backend is fully usable with pure C SANE frontends again. Note, this problem should only affect the following scanners: - GT-7200 / Perfection 1250 - GT-7300 / Perfection 1260 - GT-9400 / Perfection 3170 - GT-F600 / Perfection 4180 as these are the only ones that use libesint* modules. I know this does not solve your problem, but at least you know what is wrong. I'll file an internal bug report. -- Olaf Meeuwissen EPSON KOWA Corporation, PF1 FSF Associate Member #1962 sign up at http://member.fsf.org/ GnuPG key: 6BE37D90/AB6B 0D1F 99E7 1BF5 EB97 976A 16C7 F27D 6BE3 7D90 Penguin's lib! -- I hack, therefore I am -- LPIC-2
