GLUT doesn't work.

OpenGL OpenGL: User Software
1

I’m a new to OpenGL, I’m follow a book named “OpenGL SuperBible” by R.S.Wright,JR. I followed the instruction to set up my system(contains GLUT) and tried a very simply program:
//Program Begins:
#include <windows.h>
#include <GL/glut.h>
#include <GL/gl.h>
#include <GL/glu.h>

void RenderScene(void)
{
glClear(GL_COLOR_BUFFER_BIT);
glFlush();
}

void SetupRC(void)
{
glClearColor(0.0f,0.0f,1.0f,1.0f);
}

int main(void)
{
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutCreateWindow(“Simple”);
glutDisplayFunc(RenderScene);

SetupRC();

glutMainLoop();

return 0;
}
//Program End
When I try to compile it, It always show me this:

I’m using MinGW in Windows XP sp2, the GLUT version is 3.7.6 downloaded from this site. I really don’t know why get these errors, I’m new to OpenGL, before that, I only learned C++(NOT VC++, I’ve no experience about that.) and some Java programming. Should I learn something else? Please help me, thank you very much.

Hi, i was just experiencing same problem and after I spent 2 hours :slight_smile: by browsing and trying to find a way. I am using DevCpp and finally this is what helped.

try to put this line directly to code:

#define GLUT_DISABLE_ATEXIT_HACK

and content of my linker is:
-lglut32 -lglu32 -lopengl32 -lwinmm -lgdi32

try to change it similarly if the first trick does not work. keep it in same order.

I hope, this will help. I tried your code and it was working, actually.

Thanks a lot. I tried your suggestion yesterday, I’m sorry but it still doesn’t work well, but it’s only 6 errors now. I tried this program in VC++ 6.0, every thing goes fine, ~~~ but I doesn’t like VC++ 6.0 because it’s not standard C++, so I’m still working on it in MinGW, I really hope I can fix it. But I still thank you very much!
