Looks like libsane-hp3770.so needs to be linked to sanei_usb. > I wonder if it wouldn't be possible to incorporate the following permanently > into the standard sane-code for backends (picked up from Daniel's README > file): > > # [add "sanei_usb.lo" to the "EXTRA" line in backend/Makefile.in: > # > #diff -e backend/Makefile.in ../sane-backends-1.0.13.hp/backend/Makefile.in > #71c] > > EXTRA = sane_strstatus.lo ../sanei/sanei_init_debug.lo > ../sanei/sanei_config.lo > ../sanei/sanei_usb.lo This would link every SANE backend to sanei_usb.

The libsane-hp3770.so must just be linked to all the code it uses internally. If it uses sanei_usb, it must be linked to it. It doesn't make sense to link the dll backend to sanei_usb. I'm surprised that this works anyway. However, linking sanei_usb to a non-free binary-only library may not be allowed due to the GPL+SANE license. Bye, Henning
