Can't get LWJGL to run using IDEA and SBT

Question

I\'ve been scratching myself in the head for a little over an hour with this, nothing on Google seems to be able to give me a decisive answer.

I\'m using Intel

Answer 1

You can include LWJGL (with natives) by simply adding the following snippet to your build.sbt:

libraryDependencies ++= {
  val version = "3.1.6"
  val os = "windows" // TODO: Change to "linux" or "macos" if necessary

  Seq(
    "lwjgl",
    "lwjgl-glfw",
    "lwjgl-opengl"
    // TODO: Add more modules here
  ).flatMap {
    module => {
      Seq(
        "org.lwjgl" % module % version,
        "org.lwjgl" % module % version classifier s"natives-$os"
      )
    }
  }
}

The classifier function sadly is very undocumented so it took me some time to find this out.

I know this is quite a bit old, but I thought this might help others who come across this problem. What I did myself was download the jar file from the site, extract the natives from the jar and add them to my resources directory. As for lwjgl I added it to my sbt project as you have. During runtime, I extracted the natives from the jar and loaded the native libraries using

System.load("<native-library-name>")

then set the natives directory for lwjgl using

System.setProperty("org.lwjgl.librarypath", <natives-path>)

Also, as for extracting the natives from your jar file during runtime, you could do something like this

val source = Channels.newChannel(
NativesLoader.getClass.getClassLoader.getResourceAsStream("<native>"))

val fileOut = new File(<desination directory>, "<native path in jar>")
val dest = new FileOutputStream(fileOut)
dest.getChannel.transferFrom(source, 0, Long.MaxValue)
source.close()
dest.close()
