Question

我正在使用VS2015，并尝试了解opengl。但不知何故，我在opengl super bible 5th中的第一个例子triangle.cpp遇到了一些问题。我谷歌2个小时仍然被困在这里。

以下是代码：

// Triangle.cpp
// Our first OpenGL program that will just draw a triangle on the screen.

#include <Windows.h>
#include <GLTools.h>            // OpenGL toolkit
#include <GLShaderManager.h>    // Shader Manager Class
#include <GL\glew.h>
#ifdef __APPLE__
#include <glut/glut.h>          // OS X version of GLUT
#else
#define FREEGLUT_STATIC
#include <GL/glut.h>            // Windows FreeGlut equivalent
#endif

GLBatch triangleBatch;
GLShaderManager shaderManager;

///////////////////////////////////////////////////////////////////////////////
// Window has changed size, or has just been created. In either case, we need
// to use the window dimensions to set the viewport and the projection matrix.
void ChangeSize(int w, int h)
{
    glViewport(0, 0, w, h);
}


///////////////////////////////////////////////////////////////////////////////
// This function does any needed initialization on the rendering context. 
// This is the first opportunity to do any OpenGL related tasks.
void SetupRC()
{
    // Blue background
    glClearColor(0.0f, 0.0f, 1.0f, 1.0f);

    shaderManager.InitializeStockShaders();

    // Load up a triangle
    GLfloat vVerts[] = { -0.5f, 0.0f, 0.0f,
        0.5f, 0.0f, 0.0f,
        0.0f, 0.5f, 0.0f };

    triangleBatch.Begin(GL_TRIANGLES, 3);
    triangleBatch.CopyVertexData3f(vVerts);
    triangleBatch.End();
}



///////////////////////////////////////////////////////////////////////////////
// Called to draw scene
void RenderScene(void)
{
    // Clear the window with current clearing color
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);

    GLfloat vRed[] = { 1.0f, 0.0f, 0.0f, 1.0f };
    shaderManager.UseStockShader(GLT_SHADER_IDENTITY, vRed);
    triangleBatch.Draw();

    // Perform the buffer swap to display back buffer
    glutSwapBuffers();
}


///////////////////////////////////////////////////////////////////////////////
// Main entry point for GLUT based programs
int main(int argc, char* argv[])
{
    gltSetWorkingDirectory(argv[0]);

    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH | GLUT_STENCIL);
    glutInitWindowSize(800, 600);
    glutCreateWindow("Triangle");
    glutReshapeFunc(ChangeSize);
    glutDisplayFunc(RenderScene);

    GLenum err = glewInit();
    if (GLEW_OK != err) {
        fprintf(stderr, "GLEW Error: %s\n", glewGetErrorString(err));
        return 1;
    }

    SetupRC();

    glutMainLoop();
    return 0;
}

我得到了这些错误：

我已经完成了有关包含头文件，库和dll的所有说明。我该如何解决这个问题？

编辑：我将所有头文件添加到VC / lib文件夹和VC / lib文件夹中的库中。

Property Pages->VC++ Directories->include Directories

Property Pages->VC++ Directories->Library Directories

我认为它可以通过此设置进行链接，我可以在第2版中运行一些示例。我误解了什么吗？
