[Solved] Same code and 2 different erros
« on: June 28, 2018, 13:56:13 »
Version: LWJGL 3.1.6 build 14

All was working well before I exported one of my projects. When I ran the jar file it didn't work. So I tried IDE (Eclipse) and it gave me this error:

Code: [Select]
Exception in thread "main" java.lang.IllegalStateException: There is no OpenGL context current in the current thread.
   at org.lwjgl.opengl.GL.createCapabilities(GL.java:376)
   at org.lwjgl.opengl.GL.createCapabilities(GL.java:320)
   at HelloWorld.loop(HelloWorld.java:95)
   at HelloWorld.run(HelloWorld.java:25)
   at HelloWorld.main(HelloWorld.java:114)

I changed nothing before and after exporting and it just stopped working.
So I copied code from https://www.lwjgl.org/guide and still the same.
I took the jar and tried it on another PC and it worked! (My is WIN7 other is WIN10)
Could it be hardware issue or some wrong settings ?

Running the jar file with console gives me this error:
Code: [Select]
Exception in thread "main" java.lang.ExceptionInInitializerError

Looks like the OpenGL .dll is missing. Run the application with -Dorg.lwjgl.util.Debug=true -Dorg.lwjgl.util.DebugLoader=true to verify. Reinstalling the GPU drivers may resolve the issue.

Deleting C:\Users\{Name}\AppData\Local\Temp\lwjgl{Name} somehow helped.
Thank you for showing me the debug arguments thus helping me fix my problem.
