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 OpenGL prob.

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!

Code:

#include		<windows.h>
#include		<gl\gl.h>				// Header file for the OpenGL32 library
#include		<gl\glu.h>				// Header file for the GLu32 library
#include		"aux.h"					// Header file for the auxillary library

void display(void)
{
	GLdouble eqn[4] = {0.0,1.0,0.0,0.0};	// this arguement points to the 4 coefficients of the plane equation	
	GLdouble eqn2[4] = {1.0,0.0,0.0,0.0};	// same as above

	glClear(GL_COLOR_BUFFER_BIT);			// clears color buffer

	glColor3f(1.0,1.0,1.0);					// sets color to white
	glPushMatrix();							// this pushes the current matrix stack down by one, duplicating the current matrix
	glTranslatef(0.0,0.0,-5.0);				// this moves the current view matrix 5 units deeper into the screen

	glClipPlane(GL_CLIP_PLANE0, eqn);		// indicates the clipping plane
	glEnable(GL_CLIP_PLANE0);				// enables clip plane0
	glClipPlane(GL_CLIP_PLANE1, eqn2);		// indicates the clipping plane
	glEnable(GL_CLIP_PLANE1);				// enables clip plane1

	glRotate(90.0,1.0,0.0,0.0);				// rotates object 90 degrees on the X axis (ie it moves up and down away from the viewer)
	auxWireSphere(1.0);						// draws a wire sphere with a diameter of 1?
	glPopMatrix();							// pops the current matrix stack, replace the current matrix with the one below it on the stack
	glFlush();								// empties all the buffers causing all issued commands to execute in finite time (as quickly as they're accepted by the actual rendering engine)

}
// closes the display(void) function

void myinit(void)
{
	glShadeModel(GL_FLAT);					// this selects which type of shading is used (Flat shading selects the computed color of one vertex and assigns it to the entire object)

}


void myReshape(GLsizei w, GLsizei h)
{
	glViewport(0,0,w,h);										// specifies the affine transformation of x and y(0,0) from normalized device co ords to windows co ords
	glMatrixMode(GL_PROJECTION);								// specifies which matrix is the current matrix ie the Projection matrix stack
	glLoadIdentity();											// replaces the current matrix with the identity matrix
	gluPerspective(60.0, (GLfloat) w /(GLfloat) h, 1.0,20.0);	// sets up a perspective projection  matrix
	glMatrixMode(GL_MODELVIEW);									// specifies which matrix is the current matrix ie the Modelview matrix stack

}

int main(int argc, char** argv)								
{
	auxInitDisplayMode(AUX_SINGLE | AUX_RGBA);					// tells auxInitWindow to create a RGBA and a single buffered window
	auxInitPosition(0,0,500,500);								// tells auxInitWindow where to position a window on the screen 
	auxInitWondow(argv[0]);										// opens a window with the characteristics specificied by the two previous commands, the string argv appears in the title window)
	myinit();													// calls the myinit() function above
	auxReshapeFunc(myReshape);									// specifies the function that is called when the window is resized( in this case the myReshape() function), moved or exposed. the arguement is a pointer to a function that expects 2 parameters
	auxMainLoop(display);										// specifies the function that's called when the window needs to be updated. This function should redraw the objects on the screen
        return TRUE;
}

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!!!!
