VC++ 2010：C/C++入门环境搭建与核心调试实战指南 C/C++作为系统级编程语言，其核心在于对内存管理、数据类型和编译原理的深入理解。学习编程的第一步往往是环境配置，一个稳定、简洁的开发环境能帮助初学者聚焦语言本质，避免被复杂的工具链分散注意力。Visual C++ 2010 Express学习版正是这样一个经典选择，它提供了纯粹的C/C++开发体验，特别适合国内教育体系和自学者。通过搭建环境、编写第一个程序、掌握调试技巧，学习者可以深入理解从源代码到可执行文件的完整流程。本文以VC++ 2010为例，详细演示了如何配置开发环境、编写Hello World程阅读详情

类声明最后边的"}"要加“；”，另Load函数中的"\"要改为"\\".

这是Texture.h:

#ifndef Texture_H
#define Texture_H

#include<windows.h>
#include<gl\gl.h>
#include<gl\glu.h>
#include<gl\glaux.h>

class Texture
{
public:
char *texturename; // The textures name
unsigned int texture[1]; // OpenGL's number for the texture
int width; // Texture's width
int height; // Texture's height
void Use(); // Binds the texture for use
void BuildColorTexture(unsigned char r, unsigned char g, unsigned char b); // Sometimes we want a texture of uniform color
void LoadBMPResource(char *name); // Load a bitmap from the resources
void LoadFromResource(char *name); // Load the texture from a resource
void LoadBMP(char *name); // Loads a bitmap file
void Load(char *name); // Load the texture
Texture(); // Constructor
virtual ~Texture(); // Destructor
}

#endif Texture_H

不行啊还是那样括号好着呢~~~

还有一种可能性，就是你的头文件中，括号不对应。Texture.h中

在你的包含语句后加上：

using namespace std;
