[Message part 1 (text/plain, inline)]

Hello

> The LD_LIBRARY_PATH looks suspicious.

What exactly is suspicious?

>  Is there any way around it using other SANE tooling?

AFAIK there's no simpler runtime-only solution:
- You could use patchelf to prepend the store's lib/sane directory
onto the binary's RPATH, but that's as even even more fiddly as
setting LD_LIBRARY_PATH
- sane-config only spits out compile-time flags (-I..., -L...,
-lsane); it doesn't tell the loader where to find backends at runtime.

BTW, I've polished the patch. Please ignore the previous one - the
phase name was wrong ("wrap-flatpak" instead of "wrap-simple-scan").


Cheers
