Błędy z połączeniem sfml i opengl

Question

Mam taki kod:

#include <GL/glew.h>
#include <glfw3.h>
#include <iostream>
#include <fstream>
#include <string>
#include <cmath>
#include <glm.hpp>
#include <gtc\matrix_transform.hpp>
#include <gtc\type_ptr.hpp>
#include <SFML\Graphics.hpp>

#include "EasyLearning.h"
#include "Figures.h"

int LoadTexture(std::string file_name)
{
	GLuint tex;
	sf::Image Image;
	Image.loadFromFile(file_name);
	glGenTextures(1, &tex);
	glBindTexture(GL_TEXTURE_2D, tex);
	gluBuild2DMipmaps(GL_TEXTURE_2D, GL_RGBA, Image.getSize().x, Image.getSize().y, GL_RGBA, GL_UNSIGNED_BYTE, Image.getPixelsPtr());
	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR);

	return 0;
}
//******************************************************************************
int main()
{
	EasyLearning easy;
	easy.glewInitialization();
	GLFWwindow *window = glfwCreateWindow(600, 800, "", NULL, NULL);
	easy.glfwInitialization();

	GLfloat points[] = {
		-0.5f, -0.5f,  0.0f,
		0.5f, -0.5f,  0.0f,
		0.5f,  0.5f,  0.0f,
		0.5f,  0.5f,  0.0f,
		-0.5f,  0.5f,  0.0f,
		-0.5f, -0.5f,  0.0f,
	};

	GLfloat tex_coords[] = {
		0.0f, 0.0f,
		1.0f, 0.0f,
		1.0f, 1.0f,
		1.0f, 1.0f,
		0.0f, 1.0f,
		0.0f, 0.0f,
	};

	GLuint position_vbo = 0;
	glGenBuffers(1, &position_vbo);
	glBindBuffer(GL_ARRAY_BUFFER, position_vbo);
	glBufferData(GL_ARRAY_BUFFER, sizeof(points), points, GL_STATIC_DRAW);

	GLuint texture_coords_vbo = 0;
	glGenBuffers(1, &texture_coords_vbo);
	glBindBuffer(GL_ARRAY_BUFFER, texture_coords_vbo);
	glBufferData(GL_ARRAY_BUFFER, sizeof(tex_coords), tex_coords, GL_STATIC_DRAW);

	GLuint vao = 0;
	glGenVertexArrays(1, &vao);
	glBindVertexArray(vao);
	glBindBuffer(GL_ARRAY_BUFFER, position_vbo);
	glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 0, NULL);
	glBindBuffer(GL_ARRAY_BUFFER, texture_coords_vbo);
	glVertexAttribPointer(1, 2, GL_FLOAT, GL_FALSE, 0, NULL);
	glEnableVertexAttribArray(0);
	glEnableVertexAttribArray(1);

	GLuint shaders = easy.loadShader("C:/Shaders/textures/vertexShader.glsl", "C:/Shaders/textures/fragmentShader.glsl");
	glUseProgram(shaders);
	GLint texture_slot = glGetUniformLocation(shaders, "basic_texture");
	glUniform1i(texture_slot, 0);

	glActiveTexture(GL_TEXTURE0);
	if (LoadTexture("C:/Shaders/textures/brick.jpg"))
		return -1;

	while(!glfwWindowShouldClose)
	{
		glClearColor(0.5, 0.5, 0.5, 0.0);

		glBindVertexArray(vao);
		glDrawArrays(GL_TRIANGLES, 0, 6);

		glfwSwapBuffers(window);
		glfwPollEvents();
	}

	glfwTerminate();

	return 0;
}

i wyskakują mi takie błędy:

I nie wiem o co chodzi

Answer 1

W ogóle używasz GLU? W includach nic związanego z GLU nie widze. Dlaczego nie:

glGenerateMipmap(GL_TEXTURE_2D);

?

Answer 2

Najprawdopodobniej brakuje jednej z tych bibliotek: opengl32, glu32, gdi32
