I'm trying to express somehow this in Gradle

Copy code

It looks like you are trying to compile a shared library to create a JNI library, is that correct?

You can use directly the plugin

dev.nokee.jni-library

with regards to what you need to do for configuring, I would estimate the build script to be something similar to the following:

Copy code

plugins {
  id 'dev.nokee.jni-library'
  id 'dev.nokee.c-language'
  id 'java'
}

library {
  targetMachine = [machines.linux.x86_64]
  variants.configureEach {
    sharedLibrary {
      compileTasks.configureEach {
        compilerArgs.addAll(['-O3', '-flto', '-fPIC', '-pthread', '-DNDEBUG', '-DLWJGL_LINUX', '-DLWJGL_x64', '-D_FORTIFY_SOURCE', '-D_FORTIFY_SOURCE=0', '-D_GNU_SOURCE', '-D_FILE_OFFSET_BITS=64', '-DCONFIG_HAVE_MEMFD_CREATE'])
      }
    }
  }
}

For the includes and sources, I will need a bit more info as the relative path doesn’t confirm if the includes are part of the project or not. In general, the sources you declare on the
