hi, still playing with building a native image for javafx app written in clojure. idea is just to rewrite gluon’s HelloFX in clojure and get it built into a native image. getting somwhere: latest build for macos: unfortunately it fails with this when I try to run it:

@tvaughan reported a similar problem back in 2020 aug 20th here

benedek 2021-02-24T17:09:28.005200Z

(not with javafx tho) wonder if anybody seen similar and maybe has a pointer what to poke to fix it…

tvaughan 2021-02-24T17:16:07.009200Z

I tried many different approaches, and this didn't work until newer versions of depstar and graalvm were released. I currently use 2.0.171 and 21.0. Complete setup: Oh, and Clojure 1.10.2 too. For some reason I have to explicitly include Clojure 1.10.2 in deps.edn even though this is the only version I have installed

benedek 2021-02-24T17:17:54.010300Z

thanks i thought i was using those versions of clojure and graalvm (not using depstar), will dig around in kibit-runner, thanks for the link

benedek 2021-02-24T17:20:32.010700Z

i am lying i am using 1.10.3-rc1

borkdude 2021-02-24T17:37:53.011300Z

@benedek This problem manifests itself when a project has dynamic requires that aren't executed during compilation. The namespace is then not available anymore after compilation. GraalVM works a bit like the Google Closure compiler, cutting away code it didn't come across during analysis.

borkdude 2021-02-24T17:38:09.011700Z

You can probably work around this by requiring clojure.core.server during compilation already

borkdude 2021-02-24T17:38:44.012500Z

For whatever reason this is necessary. I think it would even be better to get to the root of what is needing clojure.core.server since this namespace seems a bit unnecessary for a JavaFX project perhaps

tvaughan 2021-02-24T17:47:08.013100Z

> You can probably work around this by requiring clojure.core.server during compilation This did not work for me, fyi

borkdude 2021-02-24T17:48:36.013600Z

I am trying now locally. I can successfully run the app with:

java -cp target/classes:$(clojure -Spath) thomasa.Main

borkdude 2021-02-24T17:48:48.013900Z

The notes are missing the compiled classes on the classpath

borkdude 2021-02-24T17:50:04.014600Z

But I can't find any details as how the native-image compilation is supposed to be kicked off with this gluon stuff

borkdude 2021-02-24T17:51:00.014800Z

Trying now with mvn client:build

borkdude 2021-02-24T17:53:09.015100Z

Ah I can reproduce the problem locally yes

borkdude 2021-02-24T17:54:34.015500Z

It might be related to --initialize-at-build-time, this is generally what you need for Clojure projects

borkdude 2021-02-24T17:56:53.015900Z

I see the pom.xml already has this for clojure, so it should work, hmm

benedek 2021-02-24T18:09:37.016300Z

thanks for looking at it @borkdude

borkdude 2021-02-24T18:10:30.017200Z

Yeah, so normally you do --initialize-at-build-time and then making exceptions with --initialize-at-runtime=... for Clojure projects

borkdude 2021-02-24T18:10:54.017700Z

Don't really know anything about JavaFX unfortunately

benedek 2021-02-24T18:11:53.018700Z

yeah that would be the main aim of this experiment to figure it out :)

benedek 2021-02-24T18:12:54.020200Z

but this error feels like related to the config you quoted above not really javafx... but guessing only...

borkdude 2021-02-24T18:16:05.020700Z

Maybe you can bug the folks at Gluon about this a bit. I know Johan Vos is on the GraalVM slack as well, you can maybe poke him in the native-image channel

borkdude 2021-02-24T18:16:12.020900Z

borkdude 2021-02-24T18:16:31.021300Z

It would help converting your notes.txt into a shell script which you can actually execute

benedek 2021-02-24T18:29:50.021800Z

yup, good idea, thx

benedek 2021-02-24T19:07:33.022600Z

the notes file maybe a bit misleading even, the github workflow file is the real definition of the build:
