Question

我一直在使用SDL学习OpenGL，但是我正在学习使用GLUT的教程，我试图切换到GLUT，因为它看起来更容易用于新手，我觉得我会更快地选择内容。我认为这将是一个简单快速，无痛的过程，但是在尝试编译GLUT内容时遇到以下问题（使用MinGW）（我已经下载了GLUT并将头文件解压缩到我的包含，因此它被正确包含在内，我还将lib文件解压缩到lib文件夹中，并且我正在链接它，我的DLL中存在.DLL for glut system32所以它被成功调用。

我对自己做错了什么一无所知，不胜感激任何帮助和建议

在编译以下小内容时构建消息（目前不会执行任何操作但应编译）：

#include <stdlib.h>
#include <GL/glut.h>

static int day = 0, year = 0;

void init()

{

glClearColor(0.0,0.0,0.0,0.0);
glShadeModel(GL_FLAT);

}

void display(void)

{

glClear(GL_COLOR_BUFFER_BIT);
glColor3f(1.0,1.0,1.0);

glPushMatrix();
glutWireSphere(1.0,20,16);
glRotatef((GLfloat) year, 0.0,1.0,0.0);
glTranslatef(2.0,0.0,0.0);
glRotatef((GLfloat) day, 0.0, 1.0, 0.0);
glutWireSphere(0.2,10,8);
glPopMatrix();
glutSwapBuffers();

}

//void reshape(int w, int h)

int main(int argc, char **argv)

{



}

构建器错误：

Answer 1

是的，我必须包含这段代码才能让它在Windows上运行。

#if defined(_WIN32) || defined(_WIN64)
#include <windows.h>
#endif

似乎windows上的链接器通过windows.h链接来访问System32中的.dll文件

Answer 2

不，你没有反对过剩（也不是gl）。或者它是一个糟糕的版本，但我怀疑。您可以尝试发布项目配置或Makefile。 _imp__gl*事物是libGL，显然glut*事情是过剩的。此外，请确保链接到链接器可识别的库格式。 * .lib文件通常是MS-COFF格式，这是微软自己的COFF标准。 mingw（ld）中的链接器将无法链接此文件。您需要一个扩展名为.a的静态库（通常）。
