Hey I appreciate the effort.
***UPDATE Dec 4***
So I finally got around to building from source, and found einkvnc does indeed work on my Kobo Clara HD, with droidVNC-NG (from F-Droid) running as VNC server on my phone! The display is upside down and there is no touch on the Kobo, but the resolution is clear and the response is good for browsing.
Note* If someone is building Plato with the Linaro build tools, they might get a GLIBC not found error as described here:
https://kobzol.github.io/rust/ci/202...der-glibc.html
I took their advice and used an old Linaro release from here:
https://releases.linaro.org/componen...nux-gnueabihf/
Also the download.sh script in the /eink-vnc-main/client/ folder referred to a non-findable target so I changed the line to:
archive="plato-0.9.34.zip"
and plopped that zip (that was produced by the plato build) in the folder.
The weird thing is, I went back and tested the original (prebuilt) binary, and it ALSO works!?!
So I'm chalking the original error up to a flaky network connection. But I'm glad it happened because it got me to 1)use the fantastic Rust build system, and 2)build and install Plato, which is a pretty cool complement to KOReader.
So congrats on the great work, and sorry for the confusion.
Einkvnc IS working on Kobo Clara HD!
