A discussion in the Arch Linux forum mentioned a [https://gist.github.com/Markismus/14e286a86fde3b6904980536e8ab9986 '''patch'''] for the ''channel-usb.c'' file, redefining the data type for variables storing RGB values, increasing the size. A potential solution found, but it still needed porting to a recent Iscan release, one able to build on recent Slackware Linux releases. I mentioned in earlier pages:

* [[~~iscan_per_Slackware_15~~.0 | Iscan and Slackware 15.0]].

* [[iscan_and_Slackware_15.0 | Iscan and Slackware 15.0]].

* [[~~iscan_per_Slackware_15~~.0_perfection_v600 | The Epson Perfection V600 plug-in]].

* [[iscan_and_Slackware_15.0_perfection_v600 | The Epson Perfection V600 plug-in]].

the sad state of Iscan source code for recent Slackware and pointed out the need to use Iscan 2.30.1 and old versions of a compiler and glibc to build a working package.

No package for Arm or 32 bits Intels ? I'm afraid not. The former because the '''Slackware 14.2 Arm port is not actively supported and [https://www.youtube.com/watch?v=JhV5NibTU6w was declared "end of life"] the past April 2023. For the latter, nobody downloaded the 32 bits packages in the past 2 years. If you need them, please write me an e-mail and I'll dug out a proper virtual machine to build them.
