Question

我正在尝试使用glew和freeglut设置openGL，使用this guide。

我已按照指南直到第7步，但在使用本书第1章中的代码进行编译时（如建议的那样），我得到下面列出的错误。我可以看到错误发生在函数_InitWindow和_RenderFunction中，但我不知道如何解决它们。

我的main.c文件中的代码是：

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <GL/glew.h>
#include <GL/freeglut.h>
#define WINDOW_TITLE_PREFIX "Chapter 1"

int CurrentWidth = 800,
    CurrentHeight = 600,
    WindowHandle = 0;

void Initialize(int, char*[]);
void InitWindow(int, char*[]);
void ResizeFunction(int, int);
void RenderFunction(void);

int main(int argc, char* argv[])
{
    Initialize(argc, argv);

    glutMainLoop();

    exit(EXIT_SUCCESS);
}

void Initialize(int argc, char* argv[])
{
    InitWindow(argc, argv);

    fprintf(
        stdout,
        "INFO: OpenGL Version: %s\n",
        glGetString(GL_VERSION)
        );

    glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
}

void InitWindow(int argc, char* argv[])
{
    glutInit(&argc, argv);

    glutInitContextVersion(4, 0);
    glutInitContextFlags(GLUT_FORWARD_COMPATIBLE);
    glutInitContextProfile(GLUT_CORE_PROFILE);

    glutSetOption(
        GLUT_ACTION_ON_WINDOW_CLOSE,
        GLUT_ACTION_GLUTMAINLOOP_RETURNS
        );

    glutInitWindowSize(CurrentWidth, CurrentHeight);

    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);

    WindowHandle = glutCreateWindow(WINDOW_TITLE_PREFIX);

    if(WindowHandle < 1) {
        fprintf(
            stderr,
            "ERROR: Could not create a new rendering window.\n"
            );
        exit(EXIT_FAILURE);
    }

    glutReshapeFunc(ResizeFunction);
    glutDisplayFunc(RenderFunction);
}

void ResizeFunction(int Width, int Height)
{
    CurrentWidth = Width;
    CurrentHeight = Height;
    glViewport(0, 0, CurrentWidth, CurrentHeight);
}

void RenderFunction(void)
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSwapBuffers();
    glutPostRedisplay();
}

在没有运气的情况下多次重做教程的步骤之后，我去了自由式找到答案（这不在教程中）。

我的问题是附加的库目录路径没有设置为我的lib文件的路径。通过右键单击项目来更改此选项，从下拉列表中选择“所有配置”，然后转到链接器 - ＆gt; general-＆gt;其他库目录 - >编辑。在我的情况下，我将其设置为“C：\ Program Files％28x86％29 \ Microsoft SDKs \ Windows \ v8.0A \ Lib”。
