Hi Dear,
I have a Java Application (with maven and without maven, both options) which uses
JPL.jar to run a query on swi-prolog (swipl-9.3.7-1.x64), so swi-prolog is called from an Java Application. I am using Apache Netbeans 21 to run the application. Windows is the OS host, but I also tried it on Linux and I got a similar error. I installed swi-prolog and then I added the environment variables (see screenshots below). I also have JDK 11.
Variable name: SWI_HOME_DIR
Variable value: C:\Program Files\swipl
Variable: Path
Value: …SWI_HOME_DIR\lib\jpl.jar;M2_HOME\bin
When I run the application I get the following error:
run:
Exception in thread “AWT-EventQueue-0” java.lang.UnsatisfiedLinkError: jpl.fli.Prolog.thread_self()I

Could you please check and let me know which one could be this issue? I have been working on this for two days now and I am not able to understand why I am getting this error. Or if you know how to customize a linux system (Ubuntu 20.04) to run the same Java App and swi-prolog, it will also be so so helpful.
Thanks so much in advance,
Best regards,
