Hi All!
this week i tried to implement JNI library written on Nim(v.1.0.2) using
templates from
[https://gist.github.com/jangko/48ba0b76716d0631560e5f2ff470256d](https://gist.github.com/jangko/48ba0b76716d0631560e5f2ff470256d)
and also jnim
[https://github.com/yglukhov/jnim](https://github.com/yglukhov/jnim) but
unfortunately on linux OS got error at runtime:
> No stack traceback available
>
> SIGSEGV: Illegal storage access. (Attempt to read from nil?)
i recognized that it happens when Java starts GC collect.
Steps to reproduce:
* empty.nim (exactly absolute empty file) compile it with nim c --app:lib
empty.nim
* Sample.java compile with javac Sample.java (see code bellow)
public class Sample
{
public static void main(String[] args)
{
System.load("/absolute/path/to/libempty.so");
//System.load("absolute\\path\\to\\empty.dll");
for(int j=0; j<5; j++){
System.out.println("Java GC starts...");
System.gc();
System.gc();
System.gc();
System.gc();
System.gc();
System.gc();
System.gc();
System.gc();
System.gc();
System.gc();
System.gc();
System.gc();
System.out.println("Java GC finished...");
}
}
}
Run
But on windows OS it works properly.
Please any suggestion on it, perhaps additional switches for Nim compiler?
Thanks.
