[gentoo-user] Anyone got the Lexmark Network Scanner Driver to work with Gentoo

[Jens Pelzetter]

Hello all,

Lexmark provides Linux Drivers for their Scanners/MFPs as RPM and Deb
packages. I was able to install the drivers on Gentoo (in a similar way
described in the Gentoo Wiki for Brother devices:
https://wiki.gentoo.org/wiki/Brother_networked_printer#Alternative:_rpm_installation
and in the Arch Linux Wiki:
https://wiki.archlinux.org/index.php/SANE/Scanner-specific_problems#Lexmark)


scanimage finds the the driver and tries using it, but then Segfaults:

# SANE_DEBUG_DLL=4 scanimage -L

Does anyone have idea whats wrong. Is the driver from Lexmark simply
faulty/not compatible with some libraries?

Best regards
