Lightweight Java Gaming Library / Re: Unable to locate library liblwjgl.so in intellij IDEA

-Dorg.lwjgl.util.DebugLoader=true is not meant to be used as a program argument to be received by your own program in the String[] args array of the main method.
Instead, it is meant (like all "-D" arguments) as a JVM argument. So, in IntelliJ IDEA you do not set this in the "Program Arguments:" edit field, but in the "VM options:" field.

Lightweight Java Gaming Library / Unable to locate library liblwjgl.so in intellij IDEA

« Last post by codedcosmos on January 03, 2020, 07:41:16 »

I'm getting the following error. When starting a project in Intellij IDEA.

Code: [Select]

[LWJGL] Failed to load a library. Possible solutions:
a) Add the directory that contains the shared library to -Djava.library.path or -Dorg.lwjgl.librarypath.
b) Add the JAR that contains the shared library to the classpath.
[LWJGL] Enable debug mode with -Dorg.lwjgl.util.Debug=true for better diagnostics.
[LWJGL] Enable the SharedLibraryLoader debug mode with -Dorg.lwjgl.util.DebugLoader=true for better diagnostics.
Stopping due to fatal error!
Successfully Wrote Crash Report!
java.lang.UnsatisfiedLinkError: Failed to locate library: liblwjgl.so
at org.lwjgl/org.lwjgl.system.Library.loadSystem(Library.java:162)

at org.lwjgl/org.lwjgl.system.Library.<clinit>(Library.java:50)
at org.lwjgl.glfw/org.lwjgl.glfw.GLFW.<clinit>(GLFW.java:674)
I have tried following https://www.youtube.com/watch?v=ZR9hNrnT2QE and https://github.com/LWJGL/lwjgl3-wiki/wiki/1.2.-Install under the "IntelliJ IDEA" subheader. Neither have worked and have given me that error message. I have also tried putting "-Dorg.lwjgl.util.DebugLoader=true" in the program arguments. But it seems to not give me any extra information. In eclipse I would fix this issue by adding the *natives*.jar files into the classpath section. But I don't think I am able to do that in intellij.

Also as expected both of the following lines return null.

Code: [Select]

System.out.println(Library.class.getResource("lwjgl.dll"));
System.out.println(Library.class.getClassLoader().getResource("lwjgl.dll"));

What can I do to fix this?

Just use the LWJGL3 bindings for Nuklear or NanoVG.

Since LWJGL 3 is not a rendering engine but (merely) Java bindings to low-level libraries like OpenGL, Vulkan, etc., any such solution will obviously depend on your own layers of abstraction in your own application/engine. You can of course simply render a line with OpenGL or Vulkan in many different ways (targeting different versions of OpenGL or Vulkan).

Lightweight Java Gaming Library / Recomendations for debug GUI?

« Last post by Peter M Ashford on December 29, 2019, 09:31:09 »

I wondered if anyone had any suggestions for making a quick and dirty debug GUI layer for LWJGL3?  Something like Gizmos in Unity where you could render lines, maybe points over top of your rendered image? 

Cheers!

Hi,

There are some Vulkan demo in the LWJGL repository, it's a good start :

OpenGL / Re: lwjgl box color leaking to background

« Last post by Animus_Surge on December 25, 2019, 06:47:07 »

Rrrrrright... but I don't understand it. GL_LIGHTING isn't even being called at all. All that I'm calling beforehand is GL_BLEND_MODE, and that's to help render transparent images.

Hello all,

How am I supposed to initialize a VkApplicationInfo?

BTW I am trying to follow https://vulkan-tutorial.com/

Thanks!

On your stacktrace you need to read the error message

API_ID_DEPRECATED_TARGET deprecated behavior warning has been generated. Enable of GL_LIGHTING capability is deprecated.

Spasi you always suprise me. Answering that quickly even in the middle of Christmas... Must give you a huge thumbsup!

You're right, initiating the class does not bind it to anything, hence when the GC is active it will screw up everything. THX!

The other problem was that I accidentally deleted `glfwPollEvents` from the main loop...
