Well, I now understand, what cause the problem. Cantor Julia backend uses Julia C API and this API requests path to some internal file (the "sys.so" file, which you mentioned before). Julia also provide method for getting path (but relative) to this file. Cantor, using information from settings, create absolute path and pass the path to julia code. The problem is, that cantor-backend-julia have been builded with system julia (I suppose, there is package "julia" in KDE Neon repos). But you pass path to local installation from jill. And relative paths to this internal file don't equal. Cantor julia backend uses "../lib/x86_64-linux-gnu/julia/" from system julia installation (from system library libjulia.so, I suppose), but for in-one-dir julia installation from jill you actually need a path "../lib/julia" (and if you manually build Cantor with Julia backend for this jill installation, then this proper path will be used and passed from Juila C API). But I have added some code for working with situation like this, so it will work in future Cantor versions. And have a more proper problem message, if there is a problem with this internal file.

SUMMARY Julia backend will 'open' a worksheet, but will fail to return. Diagnosed bug by running cantor from command line. See that it fails to find 'sys.so' in {julia binary path}/../lib/x86_64-linux-gnu/julia/ Perhaps I have an uncommon julia install, I installed with jill: https://github.com/johnnychen94/jill.py STEPS TO REPRODUCE 1. Install julia 1.4 with jill 2. Install cantor + cantor-backend-julia 3. Open a julia cantor worksheet, try to run '1+2' OBSERVED RESULT No return value etc. EXPECTED RESULT Julia will return 3 :) SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon KDE Plasma Version: 5.19.4 KDE Frameworks Version: 5.73.0 Qt Version: 5.14.2 ADDITIONAL INFORMATION Julia-1.4.1 WORKAROUND: copy sys.so file to where cantor expects it to be (create directories etc.)
