With "compiling natively", do you mean native-image?

#

ah yes I see the native-image args

#

You added --static.

#

Static images are not supported with JavaFX or Swing AFAIK

#

Also are you using the classpath or the modulepath for the native-image compilation? Can you show the full command Gradle is exeucting there?

#

Also not sure whether applicationDefaultJvmArgs is the right thing to pass native-image args

#

anyways it sais

java.lang.UnsatisfiedLinkError: com.sun.webkit.WebPage.twkInitWebCore(ZZZ)V [symbol: Java_com_sun_webkit_WebPage_twkInitWebCore or Java_com_sun_webkit_WebPage_twkInitWebCore__ZZZ]
which probably means that that native library is not available

#

which culd be due to --static

winged current Apr 16, 2024, 8:27 PM

#

interesting will certainly try that, when compiling natively I mean using Gluon (to compile to that native respected platforms binary). However it works as intended right from the IDE.

neon pilot Apr 16, 2024, 8:29 PM

#

and from the command-line without native-image?

winged current Apr 16, 2024, 8:29 PM

#

works fine without nativeimage

#

even works when I compile it if I remove the webview

#

Webview seems to be causing the application to crash

#

was thinking if it was my linux environment, since I'm new to linux. Works fine on windows.

neon pilot Apr 16, 2024, 8:30 PM

#

you are targetting Linux as well, right?

#

not Android or something like that

winged current Apr 16, 2024, 8:30 PM

#

yea and compiling from Ubuntu 64bit

#

yea Linux not for mobile

#

it's a Game Server Management tool, that uses webview for it's script editor

neon pilot Apr 16, 2024, 8:31 PM

#

and you ran the executable directly without copying it anywhere?

winged current Apr 16, 2024, 8:31 PM

#

yes using nativeRun

neon pilot Apr 16, 2024, 8:32 PM

#

oh so nativeRun directly runs the executable?

winged current Apr 16, 2024, 8:32 PM

#

which tests the executable in that current location

#

yea

#

(even without native run it crashes), but with nativeRun i geta stacktrace

neon pilot Apr 16, 2024, 8:32 PM

#

As I said, try not using --static

winged current Apr 16, 2024, 8:33 PM

#

will also that static is for gluon JavaFX applications

#

The command gluon gradle build --static refers to building a project using the Gluon plugin for Gradle with a specific option to create a static compilation of a JavaFX application. Gluon provides tools and plugins that facilitate the development of JavaFX applications for various platforms, including mobile devices (iOS and Android), embedded systems, and desktops.

but will certainly try it without it, certainly desperate

neon pilot Apr 16, 2024, 8:35 PM

#

winged current will also that static is for gluon JavaFX applications

?

winged current Apr 16, 2024, 8:35 PM

#

seen this was posted in 2022 was hoping this wasn't the case

neon pilot Apr 16, 2024, 8:35 PM

#

--static is a native-image argument for statically linked stuff

neon pilot Apr 16, 2024, 8:36 PM

#

neon pilot `--static` is a native-image argument for statically linked stuff

it also forces you to make the source code of your project available under GPL if you use it on Linux without --musl

winged current Apr 16, 2024, 8:37 PM

#

ahh great information

neon pilot Apr 16, 2024, 8:38 PM

#

but I also think I read somewhere that --static is generally not supported (from GraalVM's side) with any UI stuff

neon pilot Apr 16, 2024, 8:39 PM

#

winged current ahh great information

it's because static images include libc which is GPL-licensed

#

oh and it's --libc=musl, not --musl

#

that argumewould make it use musl instead of libc

that might be some helpful information "I had WebView/WebEngine working under slightly earlier versions (GraalVM11 and javafx-web 17.0.0.1)"

and just by updating GraalVM it doesn't work any more?
