This is just dependency stuff that you would not normally see, but since you added the print thing you now see it

🙂 thanks. looked like something I didn't need. good to confirm.

I'm getting closer... Might have 1 or 2 more questions...

I can build libyamlscript.so and it has my eval_ys_to_json entrypoint, but I get

java.lang.ExceptionInInitializerError: null
    at clojure.lang.Namespace.<init>(Namespace.java:34)
    at clojure.lang.Namespace.findOrCreate(Namespace.java:176)
    at clojure.lang.Var.internPrivate(Var.java:153)
    at libyamlscript.core.<clinit>(null:-1)
    at libyamlscript.Core.evalYsToJson(Core.java:18)

#!/usr/bin/env python3

import sys
from ctypes import *

ys_input = sys.stdin.read()

print(ys_input)

libyamlscript = CDLL("./lib/libyamlscript.so")
isolate = c_void_p()
isolatethread = c_void_p()
libyamlscript.graal_create_isolate(None, byref(isolate), byref(isolatethread))

eval_ys_to_json = libyamlscript.eval_ys_to_json
eval_ys_to_json.restype = c_char_p

print(eval_ys_to_json)

result = eval_ys_to_json(isolatethread, c_char_p(bytes(ys_input, "utf8")))

print(result)

it allows you to do Java interop on those classes, if, you also include those classes in the SCI context

Trying to determine which options are required for native-image

it seems you haven't included --initialize-at-runtime options here

currently only using

native-image \
    --silent \
    --no-fallback \
    --shared \
    -jar target/libyamlscript-0.1.0-standalone.jar \
    -cp src \
    -H:Name=/home/ingy/src/yamlscript/libyamlscript/lib/libyamlscript

yeah, this is bad

right, when I use that the build blows up

I recommend using: https://github.com/clj-easy/graal-build-time

I can look into more detail tomorrow, I have dealt with quite a few of these problems myself, if you have any links to failing builds, etc. It's night time here now, so ttyl

thanks. have a good night. I'll leave stuff here as appropriate.
