c++ - GLFW3和GLEW32:0xC0000005:访问冲突执行位置

我已经安装了所有库，例如glfw和glew。
当我运行以下代码时，我从glGenVertexArrays(1, &VertexArrayID);行收到一个错误消息，抱怨Access violation。我知道此错误是由NULL指针引起的，但我的GLuint应该不是。

    GLFWwindow* window; // (In the accompanying source code, this variable is global for simplicity)
    window = glfwCreateWindow(1024, 768, "Tutorial 01", NULL, NULL);
    glewExperimental = GL_TRUE;
    // Initialize GLEW to setup the OpenGL Function pointers
    glewInit();
    if (window == NULL) {
        printf("Failed to create window context.\n");
    }
    glfwMakeContextCurrent(window); // Initialize GLEW
    return window;
}


int main()
{
    GLFWwindow* window = GLFWInit();

    //vertex shader ID array setup:

    GLuint VertexArrayID;
    glGenVertexArrays(1, &VertexArrayID);
    glBindVertexArray(VertexArrayID);
    // some other code

    while (!glfwWindowShouldClose(window)) {
        // wipe the drawing surface clear
        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
        glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
        // update other events like input handling
        glDrawArrays(GL_TRIANGLES, 0, 12 * 3); // 12*3 indices starting at 0 -> 12 triangles -> 6 squares
        glfwPollEvents();
        // put the stuff we've been drawing onto the display
        glfwSwapBuffers(window);

    }
    glfwTerminate();
    return 0;
}

我查看了其他类似的questions，并将以下内容添加到我的代码中无济于事。

glewExperimental = GL_TRUE;
glewInit();

这是我的机器的规格(如果有帮助):

它在MS Windows 10上运行。

我的IDE是Visual Studio 2019

所有库均已正确安装。

最佳答案

一直以来这都是一个简单的错误-在我的GLFWInit函数中，在实际创建窗口之前调用了以下几行。

glewExperimental = GL_TRUE;
glewInit();

将这些行放在return window之前，但在glfwMakeContextCurrent(window)之后，使其现在可以正常工作。谢谢您的帮助。
