Ok I just got the book "OpenGL SupperBible third edition" and started to write the first "program" in Visual Studio 2005 in a .cpp file. The code is below.
#include "stdafx.h"
#include <windows.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);

}

void main(void)
{
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutCreateWindow("Simple");
glutDisplayFunc(RenderScene);

SetupRC();


glutMainLoop();

}


compile error:

and it keeps doing this down to the last line of code

c:\program files\microsoft visual studio 8\vc\platformsdk\include\wincon.h(790) : error C2146: syntax error : missing ';' before identifier 'UINT'
c:\program files\microsoft visual studio 8\vc\platformsdk\include\wincon.h(790) : fatal error C1003: error count exceeds 100; stopping compilation


I dont understand anything whats happening and Im completly confused on how to start compiling the openGL Code. Could anybody help?

I'm sure that someone else will be better than me to help you but I can tell you this :

First of all, I'd be very surprised if your compile errors came from your code, it is correct. In fact, the errors come from files that I think you shouldn't even have included. What you can do is :

- remove "stdafx.h"
- if youre using MSVC, create a new project and make sure to select an EMPTY project, then add your files, i'm not sure but you might have started your app with managed c++ which would explain the errors.

Also, I think including windows.h is not necessary but you can still do it.

The problem lies in the way you created your project, I'm pretty sure of that

You appear to have created a windows project. When using glut, you should create the project as a win32 console project (and make sure that you click on the Application Settings in the wizard and check "Create Empty Project"). Then, once you have the project created and open, right click on it in the solution explorer, go into properties, and under c/c++->general you need to add the include directories for glut in the Additoin INclude directories field, and under Linker->Input you need to add glut32.lib in the additional dependencies field.

Ok good and bad. I got rid of

\vc\platformsdk\include\wincon.h

compile error. But now I got a new one

CODE:

//#include "stdafx.h"
//#include <windows.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);

}

void main(void)
{
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutCreateWindow("Simple");
glutDisplayFunc(RenderScene);

SetupRC();


glutMainLoop();

}

HOWEVER.... smitty1276 I tried doing what you said and created a win32 console app with empty project set but when I go to properties in the solution explorer I get

problemPick-1-th.JPGbanner7.png

i couldnt find

"and under c/c++->general you need to add the include directories for glut in the Additoin INclude directories field, and under Linker->Input you need to add glut32.lib in the additional dependencies field."(smitty1276)

Did I do something wrong? Thanks guys for all the help.

Also the book is really a good book... but for openGL. It doesnt really go into all the minor details for example setting up a compiler. Which I cant blame the book since there are alot(almost all probally) that can compile openGL.(if they have the glut3.7)

Your pic shows a properties page for the solution... you need to right click on THE PROJECT, and you should see what I was talking about.

You have to include windows.h (assuming you're using windows [smile]) before the openGL headers (due to API issues). Also, it may just be my sight, but are you including glut.h anywhere? If he had any problems with the .lib files, he'd be getting linking errors, not syntax.

Hope that helps

There, fixed.
If glut.h is not located in the GL-directory, fix that manually.

HTH,
Pat.

Well, I told him to add the glut include directories in project settings... The next post would have been complaining about the linker errors, so I told him to add the lib directory as well. [wink]

OMG this is insane. Ok I have glut.h in the following path.

C:\Program Files\Microsoft Visual Studio 8\VC\include\GL\glut.h


I ran the code again and it gave me the following error.

CODE:



#include <GL/glut.h>


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

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

}

void main(void)
{
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutCreateWindow("Simple");
glutDisplayFunc(RenderScene);

SetupRC();

glutMainLoop();

}




This makes no sense to me. I went to the solution explorer added the needed directories. I put all the headers files that came with glut3.7 in the path at the top of the page. the glut32.lib file is in

C:\Program Files\Microsoft Visual Studio 8\VC\lib\glut32.lib

If anyone can help Again Thanks.
