Compile error with OpenGL - opengl

Question

Here is the program that I am trying to run
////////////////////////////////////////////////////
// square.cpp
//
// Stripped down OpenGL program that draws a square.
//
// Sumanta Guha.
////////////////////////////////////////////////////
#include <iostream>
#ifdef __APPLE__
# include <GLUT/glut.h>
#else
# include <GL/glut.h>
#endif
using namespace std;
// Drawing (display) routine.
void drawScene(void)
{
// Clear screen to background color.
glClear(GL_COLOR_BUFFER_BIT);
// Set foreground (or drawing) color.
glColor3f(0.0, 0.0, 0.0);
// Draw a polygon with specified vertices.
glBegin(GL_POLYGON);
glVertex3f(20.0, 20.0, 0.0);
glVertex3f(80.0, 20.0, 0.0);
glVertex3f(80.0, 80.0, 0.0);
glVertex3f(20.0, 80.0, 0.0);
glEnd();
// Flush created objects to the screen, i.e., force rendering.
glFlush();
}
// Initialization routine.
void setup(void)
{
// Set background (or clearing) color.
glClearColor(1.0, 1.0, 1.0, 0.0);
}
// OpenGL window reshape routine.
void resize(int w, int h)
{
// Set viewport size to be entire OpenGL window.
glViewport(0, 0, (GLsizei)w, (GLsizei)h);
// Set matrix mode to projection.
glMatrixMode(GL_PROJECTION);
// Clear current projection matrix to identity.
glLoadIdentity();
// Specify the orthographic (or perpendicular) projection,
// i.e., define the viewing box.
glOrtho(0.0, 100.0, 0.0, 100.0, -1.0, 1.0);
// Set matrix mode to modelview.
glMatrixMode(GL_MODELVIEW);
// Clear current modelview matrix to identity.
glLoadIdentity();
}
// Keyboard input processing routine.
void keyInput(unsigned char key, int x, int y)
{
switch(key)
{
// Press escape to exit.
case 27:
exit(0);
break;
default:
break;
}
}
// Main routine: defines window properties, creates window,
// registers callback routines and begins processing.
int main(int argc, char **argv)
{
// Initialize GLUT.
glutInit(&argc, argv);
// Set display mode as single-buffered and RGB color.
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
// Set OpenGL window size.
glutInitWindowSize(500, 500);
// Set position of OpenGL window upper-left corner.
glutInitWindowPosition(100, 100);
// Create OpenGL window with title.
glutCreateWindow("square.cpp");
// Initialize.
setup();
// Register display routine.
glutDisplayFunc(drawScene);
// Register reshape routine.
glutReshapeFunc(resize);
// Register keyboard routine.
glutKeyboardFunc(keyInput);
// Begin processing.
glutMainLoop();
return 0;
}
I am certain I have glut and OpenGL installed and up to date, and this is the error that I am getting (I am compiling the code the way it is laid out in the book which is from 2011):
ubuntu:~/Downloads/Code$ gcc square.cpp -o square -I
/usr/include/ -L /usr/lib -lglut -lGL -lGLU -lX11
/tmp/ccAq6h4h.o:square.cpp:function
__static_initialization_and_destruction_0(int, int): error: undefined reference to 'std::ios_base::Init::Init()'
/tmp/ccAq6h4h.o:square.cpp:function
__static_initialization_and_destruction_0(int, int): error: undefined reference to 'std::ios_base::Init::~Init()' collect2: ld returned 1
exit status
I wrote my own code and left it as a c file and it compiled

Answer 1

Was a simple error of wrong files being compiled.
