7757 :: Error while trying to use JNim

• Technisha (orginal) [2021-04-07T02:26:42+02:00] view original

  Heya everyone! I'm attempting to make a wrapper for Paper, which is a server software written in Java. So I'm using JNim, but i am unable to actually run thr produced binary, any help would be appreciated! Code:

  import jnim
  
  jclass net.minecraft.server.Main of JVMObject:
    proc main()
  
  initJNI()
  
  var MCMain = new Main
  
  MCMain.main
  Run

  Error:

   (most recent call last)                                     /home/pi/PaperNim/nim/main.nim(10) main                               /home/pi/.nimble/pkgs/jnim-0.5.1/jnim/private/jni_generator.nim(490) main                                                                   /home/pi/.nimble/pkgs/jnim-0.5.1/jnim/private/jni_api.nim(235) getMethodId                                                                  SIGSEGV: Illegal storage access.

  As a quick guess, try adding constructor definition to jclass:

  jclass net.minecraft.server.Main of JVMObject:
    proc new()
    proc main()
  Run
