C++ Engine.exe中0x00000000处未处理的异常：0xC0000005:访问冲突

我尝试构建本教程：

在window.cpp中使用以下代码：

// Include standard headers
#include <stdio.h>
#include <stdlib.h>

// Include GLEW
#include <GL/glew.h>

// Include GLFW
#include <GL/glfw.h>

// Open a window and create its OpenGL context
if( !glfwOpenWindow( 1024, 768, 0,0,0,0, 32,0, GLFW_WINDOW ) )

    fprintf(stderr, "Failed to initialize GLEW\n");
    return -1;
}

glfwSetWindowTitle( "Tutorial 02" );

// Ensure we can capture the escape key being pressed below
glfwEnable( GLFW_STICKY_KEYS );

// Dark blue background
glClearColor(0.0f, 0.0f, 0.3f, 0.0f);

glGenVertexArrays(1, &VertexArrayID);
glBindVertexArray(VertexArrayID);

// Create and compile our GLSL program from the shaders

     1.0f, -1.0f, 0.0f,
     0.0f,  1.0f, 0.0f,

    glClear( GL_COLOR_BUFFER_BIT );

    // Use our shader
    glUseProgram(programID);

    // 1rst attribute buffer : vertices
    glEnableVertexAttribArray(0);
    glBindBuffer(GL_ARRAY_BUFFER, vertexbuffer);
    glVertexAttribPointer(
        0,                  // attribute 0. No particular reason for 0, but must match the layout in the shader.
        3,                  // size
        GL_FLOAT,           // type
        GL_FALSE,           // normalized?
        0,                  // stride
        (void*)0            // array buffer offset
    );

    // 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
while( glfwGetKey( GLFW_KEY_ESC ) != GLFW_PRESS &&
       glfwGetWindowParam( GLFW_OPENED ) );

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

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

return 0;
}

我读到过指针NULL（它发现它在shader.cpp中使用了4次）如果经常使用，可能会使程序崩溃。听起来是这样，我可以将它们全部更改为0或0L，但这并不能解决问题。

真的看不出您是如何遇到这个问题的。 但是您可以从该站点下载源代码。

---

运行它并与您自己的代码进行比较。

更改NULL的值是一个愚蠢的想法，解决不了任何问题。错误的是代码，而不是NULL的值。您需要调试代码并找出为什么某个指针为null并试图取消引用。您调用了

null

函数指针。该指针始终在代码的这一部分中使用：glShaderSource（VertexShaderID，1，&VertexSourcePointer，null）；glShaderSource具有以下变量：着色器、计数、字符串、长度；规范说明：数组中的字符串数由count指定。如果长度为NULL，则假定每个字符串都以NULL结尾。忘了提一下，我还看到了堆栈损坏时的堆栈跟踪。返回地址将替换为

0

，当您到达

ret

指令时。。。它看起来和调用

NULL

一样。我用站点的projekt配置文件尝试了这一点，效果很好，看起来我的projekt配置失败了。谢谢；）
