Linux: problem with libopencv running SikuliX from Jython 2.7.3 (SikuliX on python.path)

[Pierregvx]

I am on ubuntu using :

• jython2.7.3
• sikulixidelux-2.0.6
• java : openjdk version "19.0.2" 2023-01-17 I tried to run a simple script from the following folder

├── image
│   └── firefox.png
└── run.py

here is run.py :

import org.sikuli.script.SikulixForJython
from sikuli import *
import org.sikuli.script.ImagePath
setBundlePath("image")
click()
type(Key.WIN)
click("firefox.png")

when I run /path/to/jython/bin/jython -Dpython.path=/path/to/sikulixidelux-2.0.6-20220817.114703-15.jar run.py I get this message error

I installed libopencv_java454.so and added it to the path but I still got the same error

by running strace -o strace.txt -f -e openat,stat /path/to/jython/bin/jython -Dpython.path=/path/to/sikulixidelux-2.0.6-20220817.114703-15.jar run.py I figured that the only right call for the libopencv file was in ./Simulix/SimulixLibs so I copied the library in this folder and it is now working

I have to check.
