我尝试构建此教程：this one

在window.cpp中使用以下代码：

// Include standard headers

    );

    // Draw the triangle !
    glDrawArrays(GL_TRIANGLES, 0, 3); // From index 0 to 3 -> 1 triangle

    glDisableVertexAttribArray(0);

    // Swap buffers
    glfwSwapBuffers();

} // Check if the ESC key was pressed or the window was closed

       glfwGetWindowParam( GLFW_OPENED ) );

// Close OpenGL window and terminate GLFW
glfwTerminate();

// Cleanup VBO
glDeleteBuffers(1, &vertexbuffer);
glDeleteVertexArrays(1, &VertexArrayID);

以下代码在shader.cpp

但是当在调试模式下运行代码（我从教程文件中复制完整代码）时，我的程序启动，但是它打开了Microsoft Visual C ++ 2010 Express的错误窗口，该窗口包含以下错误：

Unhandled exception at 0x00000000 in Engine.exe: 0xC0000005: Access violation.

我的堆栈包含：

ntdll.dll!__RtlUserThreadStart@8()  + 0x1b bytes

我已经读过指针NULL（它发现它在shader.cpp中使用了4次）如果经常使用它会使程序崩溃。听起来如此，我可以将它们全部更改为0或0L，但这不会解决它。
