c++ - glew 和 glfw 的 opengl 初始化问题

Question

我开始学习 OpenGL 的东西，但不幸的是，我无法正确进行初始化。 我添加了 glfw 和 glew 库，这些函数给我一个奇怪的错误， 我怎样才能让它发挥作用？

代码:

#include <iostream>
#include <GL/glew.h>
#include <GLFW/glfw3.h>

int main(void)
{
GLFWwindow* window;

/* Initialize the library */
if (!glfwInit())
{
    std::cout << "GLFW initialization failed.\n";
    return -1;
}
if (glewInit()!=GLEW_OK)
{
    std::cout << "GLEW initialization failed.\n";
    return -1;
}
window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);

if (!window)
{
    glfwTerminate();
    std::cout << "Wiondow failed.\n";
    return -1;
}

/* Make the window's context current */
glfwMakeContextCurrent(window);
/* Loop until the user closes the window */
while (!glfwWindowShouldClose(window))
{
    /* Render here */
    glClear(GL_COLOR_BUFFER_BIT);

    /* Swap front and back buffers */
    glfwSwapBuffers(window);

    /* Poll for and process events */
    glfwPollEvents();
}


glfwTerminate();
return 0;
}

链接 GLEW库正确，必须设置正确的预处理器定义。参见 GLEW - Installation :

[...] On Windows, you also need to define the GLEW_STATIC preprocessor token when building a static library or executable, and the GLEW_BUILD preprocessor token when building a dll [...]
