修改后的Opengl访问冲突

Question

我目前正在学习如何使用OpenGL for Windows。 要检查我是否正确设置了库，我正在编译一组应该有用的教程。

现在我正在关注这个集合： http://www.opengl-tutorial.org/beginners-tutorials/tutorial-2-the-first-triangle/

上一个教程编译得很好，所以我确信我已经正确设置了所有内容，但第二个一直让我搞砸了，我也无法找到任何问题。 我正在使用Visual Express c ++ 2010。

在源文件中我有：

main.cpp中：

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

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

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

// Include GLM
#include <glm/glm.hpp>
using namespace glm;

#include "shader.h"

int main( void )
{
// Initialise GLFW
if( !glfwInit() )
{
    fprintf( stderr, "Failed to initialize GLFW\n" );
    return -1;
}

glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 4);
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

// Open a window and create its OpenGL context
if( !glfwOpenWindow( 1024, 768, 0,0,0,0, 32,0, GLFW_WINDOW ) )
{
    fprintf( stderr, "Failed to open GLFW window. If you have an Intel GPU, they are not 3.3 compatible. Try the 2.1 version of the tutorials.\n" );
    glfwTerminate();
    return -1;
}

// Initialize GLEW
if (glewInit() != GLEW_OK) {
    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);

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

// Create and compile our GLSL program from the shaders
GLuint programID = LoadShaders( "SimpleVertexShader.vertexshader", "SimpleFragmentShader.fragmentshader" );


static const GLfloat g_vertex_buffer_data[] = { 
    -1.0f, -1.0f, 0.0f,
     1.0f, -1.0f, 0.0f,
     0.0f,  1.0f, 0.0f,
};

GLuint vertexbuffer;
glGenBuffers(1, &vertexbuffer);
glBindBuffer(GL_ARRAY_BUFFER, vertexbuffer);
glBufferData(GL_ARRAY_BUFFER, sizeof(g_vertex_buffer_data), g_vertex_buffer_data, GL_STATIC_DRAW);

do{

    // Clear the screen
    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;
}

shader.cpp：

#include <stdio.h>
#include <string>
#include <vector>
#include <iostream>
#include <fstream>
#include <algorithm>
using namespace std;

#include <stdlib.h>
#include <string.h>

#include <GL/glew.h>

#include "shader.h"

GLuint LoadShaders(const char * vertex_file_path,const char * fragment_file_path){

// Create the shaders
GLuint VertexShaderID = glCreateShader(GL_VERTEX_SHADER);
GLuint FragmentShaderID = glCreateShader(GL_FRAGMENT_SHADER);

// Read the Vertex Shader code from the file
std::string VertexShaderCode;
std::ifstream VertexShaderStream(vertex_file_path, std::ios::in);
if(VertexShaderStream.is_open()){
    std::string Line = "";
    while(getline(VertexShaderStream, Line))
        VertexShaderCode += "\n" + Line;
    VertexShaderStream.close();
}

// Read the Fragment Shader code from the file
std::string FragmentShaderCode;
std::ifstream FragmentShaderStream(fragment_file_path, std::ios::in);
if(FragmentShaderStream.is_open()){
    std::string Line = "";
    while(getline(FragmentShaderStream, Line))
        FragmentShaderCode += "\n" + Line;
    FragmentShaderStream.close();
}



GLint Result = GL_FALSE;
int InfoLogLength;



// Compile Vertex Shader
printf("Compiling shader : %s\n", vertex_file_path);
char const * VertexSourcePointer = VertexShaderCode.c_str();
glShaderSource(VertexShaderID, 1, &VertexSourcePointer , NULL);
glCompileShader(VertexShaderID);

// Check Vertex Shader
glGetShaderiv(VertexShaderID, GL_COMPILE_STATUS, &Result);
glGetShaderiv(VertexShaderID, GL_INFO_LOG_LENGTH, &InfoLogLength);
std::vector<char> VertexShaderErrorMessage(InfoLogLength);
glGetShaderInfoLog(VertexShaderID, InfoLogLength, NULL, &VertexShaderErrorMessage[0]);
fprintf(stdout, "%s\n", &VertexShaderErrorMessage[0]);




// Compile Fragment Shader
printf("Compiling shader : %s\n", fragment_file_path);
char const * FragmentSourcePointer = FragmentShaderCode.c_str();
glShaderSource(FragmentShaderID, 1, &FragmentSourcePointer , NULL);
glCompileShader(FragmentShaderID);

// Check Fragment Shader
glGetShaderiv(FragmentShaderID, GL_COMPILE_STATUS, &Result);
glGetShaderiv(FragmentShaderID, GL_INFO_LOG_LENGTH, &InfoLogLength);
std::vector<char> FragmentShaderErrorMessage(InfoLogLength);
glGetShaderInfoLog(FragmentShaderID, InfoLogLength, NULL, &FragmentShaderErrorMessage[0]);
fprintf(stdout, "%s\n", &FragmentShaderErrorMessage[0]);




// Link the program
fprintf(stdout, "Linking program\n");
GLuint ProgramID = glCreateProgram();
glAttachShader(ProgramID, VertexShaderID);
glAttachShader(ProgramID, FragmentShaderID);
glLinkProgram(ProgramID);

// Check the program
glGetProgramiv(ProgramID, GL_LINK_STATUS, &Result);
glGetProgramiv(ProgramID, GL_INFO_LOG_LENGTH, &InfoLogLength);
std::vector<char> ProgramErrorMessage( max(InfoLogLength, int(1)) );
glGetProgramInfoLog(ProgramID, InfoLogLength, NULL, &ProgramErrorMessage[0]);
fprintf(stdout, "%s\n", &ProgramErrorMessage[0]);


glDeleteShader(VertexShaderID);
glDeleteShader(FragmentShaderID);

return ProgramID;
}

在标题中我有：

shader.h：

#ifndef SHADER_H
#define SHADER_H

GLuint LoadShaders(const char * vertex_file_path,const char * fragment_file_path);

#endif

在资源文件中我有：

SimpleFragmentShader.fragmentshader：

 #version 330 core

// Ouput data
out vec3 color;

void main()
{

// Output color = red 
color = vec3(1,0,0);

}

SimpleVertexShader.vertexshader：

 #version 330 core

// Input vertex data, different for all executions of this shader.
layout(location = 0) in vec3 vertexPosition_modelspace;

void main(){

gl_Position.xyz = vertexPosition_modelspace;

}

调试：

从教程1：

  

您也可以从Visual Studio内部启动任何教程   首先需要设置工作目录：右键单击   操场，选择调试，工作目录，浏览和导航   到C：\ Users \ XYZ \ Projects \ OpenGLTutorials \ playground。验证。   再次右键单击Playground，“选择启动项目”。您   现在可以按F5调试代码。

我刚刚修改了教程，因为有很多人对此感到困惑。

更重要的是，如果您使用GLEW的标准版本而不是与教程捆绑的版本，则由于GLEW错误，您将无法使用核心配置文件。使用

glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_COMPAT_PROFILE);

而不是

glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
