Witam,
Zapisałem przykladowy kod z oficjalnego tutoriala http://www.lwjgl.org/guide. Podłączyłem pliki .jar i native do projektu i niestety otrzymuję wyjątek:
Exception in thread "main" java.lang.RuntimeException: Failed to create the GLFW window
at HelloWorld.init(HelloWorld.java:54)
at HelloWorld.run(HelloWorld.java:22)
at HelloWorld.main(HelloWorld.java:107)
Dlaczego otrzymuję ten wyjątek i nie mogę utworzyć okna? Czy ma to związek z systemem operacyjnym (Windows 10) i zintegrowaną kartą graficzną? Nigdzie nie mogę znaleźć podobnych problemów.
