LWJGL: Opening window causes program to crash

Question

I am attempting to make a simple game in Java / LWJGL. I was following a tutorial that was made on windows and I'm using a mac. I copied his code for opening up a window character for character and the program crashed instantly giving me a very long and weird error that probably has something to do with pointers (I don't actually know). Here is the line for creating a window that I used where width and height are defined in the properties:

 window = glfwCreateWindow(width, height, "Flappy Bird", NULL, NULL);

When I run it on my mac, it gives me this error:

libc++abi.dylib: terminating with uncaught exception of type NSException

A window also pops up that says, "java quit unexpectedly while using the libglfw.dylib plug-in."

Did I install LWJGL wrong or is my code flawed? Thanks for the help!

Answer 1

Make sure you run your application with jvm flag -XstartOnFirstThread. Although this seems to be specifically about OSX. See this SO Answer what this argument means

Answer 2

if you are using LWJGL 3 I recommend you to follow Oskar's video tutorial for setting your project and display.

Workspace setting

Display tutorial

And try to use MemoryUtil.NULL instead of standard null in your glfwCreateWindow call.
