[sane-devel] Epkowa failed to find all required interpreter API

[Scott Barnham]

Hi.

I'm struggling to get an Epson Perfection 4180 Photo scanner to work
with the Epkowa back-end.  I'm running Ubuntu Dapper.

I get message: "Failed to find all required interpreter API".  I can't
find any reference to this, so I'm a bit stuck.  Any idea what it means?

scanimage finds the USB device and attaches.  libesint43.so is installed
and it appears the back-end is finding it (scanimage used to error
loading the library before I installed it from the rpm).  I can see the
firmware file at /usr/share/iscan/esfw43.bin.  iscan fails to load,
complaining it can't find libesmod.so.1 (which is there
in /usr/local/lib), but I understand this isn't required by sane.

This is the relevant output from: SANE_DEBUG_EPKOWA=255 scanimage -L

Thanks for your help.
