I'm trying to build a JavaFx and compile it to native with GluonFX. Recently I needed to add a feature that uses a native C Library. I used org.graalvm.nativeimage for this.
The problem I'm having is that the "Link" step fails because it doesn't find the library I need to use, or that's what I'm think. This is the output of the error:
Creating library [path to project].lib and object [path to project].exp
[project].obj : error LNK2001: unresolved external symbol tt_init
[project].exe : fatal error LNK1120: 1 unresolved externals
I tried to copy the library in the graalvm libs folder indicated in the Link step, but that doesn't work.
Do you know the configuration I need to add in Maven or the GluonFx plugin to indicate to the plugin to load this library too?
Thanks in advance
Edited:
After suggestions of @JosePereda, bumped the version of gluonfx-maven-plugin to 1.0.13-SNAPSHOT and added the arguments:
<linkerArgs>
<arg>-l$lib</arg>
<arg>-L$C:/[path to the library]/ttcmp/ttcmp.lib</arg>
</linkerArgs>
But now I'm having the given error in the link step after execution of mvn clean gluonfx:build:
