türü için serbest() yöntemi tanımlanmamışsa, kararlı LWJGL 3.0.0b sürümünü yükledim ve https://www.lwjgl.org/guide adresinde bulunan pencere oluşturma örneğini takip etmeye çalışıyorum. Ancak, "GLFWKeyCallback" için "free() yöntemi tanımlanmamış" ve "GLFWErrorCallback türü" için "free() undefined yöntemi") alıyorum. Free() yönteminin GLFWKeyCallback ve GLFWErrorCallback sınıflarında olması gerekiyordu, ancak görünüşe göre, orada değil. Bu sorunu nasıl giderebilirim? Teşekkürler.
