So, i have the following code from the Red Book ([url]http://fly.cc.fer.hr/~unreal/theredbook/chapter01.html[/url]): #include <GL/gl.h> #include "aux.h" int main(int argc, char** argv) { auxInitDisplayMode (AUX_SINGLE | AUX_RGBA); auxInitPosition (0, 0, 500, 500); auxInitWindow (argv[0]); glClearColor (0.0, 0.0, 0.0, 0.0); glClear(GL_COLOR_BUFFER_BIT); glColor3f(1.0, 1.0, 1.0); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0); glBegin(GL_POLYGON); glVertex2f(-0.5, -0.5); glVertex2f(-0.5, 0.5); glVertex2f(0.5, 0.5); glVertex2f(0.5, -0.5); glEnd(); glFlush(); sleep(10); } /* as part of a single connected line strip */ glLineStipple (1, 0x1C47); glBegin (GL_LINE_STRIP); for (i = 0; i < 7; i++) glVertex2f (50.0 + ((GLfloat) i * 50.0), 75.0); glEnd (); /* in 4th row, 6 independent lines, */ /* with dash/dot/dash stipple */ for (i = 0; i < 6; i++) { drawOneLine (50.0 + ((GLfloat) i * 50.0), 50.0, 50.0 + ((GLfloat)(i+1) * 50.0), 50.0); } /* in 5th row, 1 line, with dash/dot/dash stipple */ /* and repeat factor of 5 */ glLineStipple (5, 0x1C47); drawOneLine (50.0, 25.0, 350.0, 25.0); glFlush (); } int main(int argc, char** argv) { auxInitDisplayMode (AUX_SINGLE | AUX_RGBA); auxInitPosition (0, 0, 400, 150); auxInitWindow (argv[0]); myinit (); auxMainLoop(display); } and i get around 26 errors in Borland C++ 5.5. They look like this: Error E2141 C:\Borland\BCC55\Include\GL/gl.h 1153: Declaration syntax error Error E2238 C:\Borland\BCC55\Include\GL/gl.h 1154: Multiple declaration for 'WIN GDIAPI' Please help me, i want to learn OpenGL.

First of all your slash is going the wrong way.

#include <GL\gl.h>

Second I'm pretty sure your second include should be

#include <GL\glaux.h>

No no no! The slash is going the right way!!! #include <GL/gl.h> is correct. And for glaux it is probably #include <GL/glaux.h>

The backslash would only work on Windows, so using a forward slash in path names should be prefered as this is supposed to work on all platforms.
