Hi, I want to install a running sikuliX environment on my ubuntu/lubuntu 18.04.3 LTS.
standard apt-get install sikulix installs very well, but is not runable. no UI comes up. tons of java error messages..
So I´m trying this commands over here, but do I get the opencv 2.4 *.so files from ??
can´t find any hint on that :-/
thx4help
