Oh, darn. Well, that looks correct.....

Is there an appropropriate .deps.json generated along with it?

lytico commented 1 month ago

yes, i think so ...

Limaki.UnitsOfWork.DocumentModel.PlantUml.Runner.deps.json

wasabii commented 1 month ago

Can you run ldd against libikvm.so?

Can you try to set the env variable IKVM_LIBRARY_PATH to the runtimes/linux-x64/native path in the output?

Just to verify it loads it that way.

This is a bug. I have it reproducing on my end. Somehow NativeLibrary isn't loading from .deps.json like it should.

wasabii commented 1 month ago

Got it. Will release patch .... by tomorrow.

lytico commented 1 month ago

thanks for the fast patch!

it's working now with the .csproj given as example above

info

i updated to the latest version of plantuml 1.2024.6, and it works fine too - just in case you'll ever asked for ikvm - plantuml-compatibility like in this issue #466
