Errors with header files in OpenGL using VisualC++

Hi, my name is Danny and I am very new to Visual C++ and OpenGL. I began using NeHe's tutorials and everything was going great. Later, I wanted to try some clipping so I transfered this code from OpenGL Programming Guide (the red book, pg 107):

Code:

---


#include <windows.h>
#include <gl\gl.h>
#include <gl\glu.h>
#include "aux.h"

void display(void)
{
GLdouble eqn[4] = {0.0,1.0,0.0,0.0};
GLdouble eqn2[4] = {1.0,0.0,0.0,0.0};

glClear(GL_COLOR_BUFFER_BIT);

glColor3f(1.0,1.0,1.0);
glPushMatrix();
glTranslatef(0.0,0.0,-0.5);

glClipPlane(GL_CLIP_PLANE0, eqn);
glEnable(GL_CLIP_PLANE0);
glClipPlane(GL_CLIP_PLANE1, eqn2);
glEnable(GL_CLIP_PLANE1);

glRotate(9.0,1.0,0.0,0.0);
auxWireSphere(1.0);
glPopMatrix();
glFlush();

}


void myinit(void);
{
glShadeModel(GL_FLAT);
}


void myReshape(GLsizei w, GLsizei h)
{
glViewport(0,0,w,h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(60.0, (GLfloat) w /(GLfloat) h, 1.0,20.0);
glMatrixMode(GL_MODELVIEW);

}

int main(int argc, char** argv);
{
auxInitDisplayMode(AUX_SINGLE | AUX_RGBA);
auxInitPosition(0,0,500,500);
auxInitWondow(argv[0]);
myinit();
auxReshapeFunc(myReshape);
auxMainLoop(display)

}

---

this is the first time I encountered these errors. This is just a few of the errors I recieved:

c:\program files\microsoft visual studio\vc98\include\gl\glu.h(384) : error C2165: 'left-side modifier' : cannot modify pointers to data
c:\program files\microsoft visual studio\vc98\include\gl\glu.h(384) : error C2071: 'GLUnurbsErrorProc' : illegal storage class

c:\program files\microsoft visual studio\vc98\include\gl\glut.h(605) : error C2146: syntax error : missing ')' before identifier 'type'


After trying to resolve these problems and making sure I linked the appropriate libraries(OpenGL32.lib GLu32.lib GLaux.lib), I placed the above code in a newly downloaded NeHe tutorial and I got the same errors. Now everything I compile in Visual C++ is incurring the same errors, whether they are simple programs I wrote or tutorials I downloaded!!

I would greatly appreciate some assistance regarding this issue, thanks and have a great day!!

Have you been able to successfully compile any programs in OpenGL? If not, are you sure that it is correctly configured for MSVC++? Did you put the correct include and library directories in so it knows where to look for them?

... continued from http://cboard.cprogramming.com/showthread.php?t=55663.

Code:

---

int main(int argc, char** argv);
{
auxInitDisplayMode(AUX_SINGLE | AUX_RGBA);
auxInitPosition(0,0,500,500);

---

That semicolon is causing some problems.

Code:

---

void myinit(void);
{
glShadeModel(GL_FLAT);
}

---

Same here.

You're missing a semicolon here:

Code:

---

int main(int argc, char** argv);
{
auxInitDisplayMode(AUX_SINGLE | AUX_RGBA);
auxInitPosition(0,0,500,500);
auxInitWondow(argv[0]);
myinit();
auxReshapeFunc(myReshape);
auxMainLoop(display);

}

---

And there should probably be a return 0 at the end of main().

Thanks alot!!! I did make a few mistakes coping the code unfortunately those errors didn't change anything. I still have the same amount of errors!!

I was told to put in the glut header file, but that doesn't change anything. this is the modified code. I added return O; then return TRUE, still no change.

To Morgul: Initially all the tutorials I downloaded and the programs I wrote were compiling. After I encountered this errors, all the other projects had the same errors! (However, I didn't try to compile a project without graphics). I included the correct libraries and linked them to the project. Thanks!

thanks for all the help!!! If you know of any websites or books that will give me assistance with this project I would greatly appreciate it. Have a great day!!!! :D
