OpenGL installation tutorial

1. Environment introduction

• Operating system: windows10 home Chinese version
• System Type: 64-bit OS, x64-based processor
• vs version: visual studio 2013

Second, opengGL environment configuration

2.1 Here we have three resource files, namely dll, GL and lib folders

• Dynamic link library dll (dynamic link library)

  

• GL file

  

• lib file

  

2.2 Copy the contents of the three folders to the corresponding directory

• Dynamic link library dll (dynamic link library)

  C:\Windows\System32
  C:\Windows\SysWOW64

• GL file

  D:\vs\VC\include
  Note: D:\vs is the installation directory of my vs2013

• lib file

  D:\vs\VC\lib

2.3 Environment configuration in visual studio

• Right-click the opengGL project created

• Select Properties at the bottom

• Find the Additional include Directories option and add the path where the header file resources are located (the GL folder mentioned in section 2.1 is found here)
  

  

• Find the Additional Libraries Directories option and add the path where the library file resources are located (the lib folder mentioned in section 2.1 is found here)

• Add Lib dependencies in Linker/input/Addtional Dependencies
  GLAUX.LIB
  glew32.lib
  glew32mx.lib
  glew32mxs.lib
  glew32s.lib
  OPENGL32.LIB
  glut32.lib
  glut.lib
  GLU32.LIB

  

3. Environmental testing

#define GLUT_DISABLE_ATEXIT_HACK
#include <Windows.h>
#include <glut.h>      // (or others, depending on the system in use)

void init(void)
{
    glClearColor(1.0, 1.0, 1.0, 0.0);  // Set display-window color to white.

    glMatrixMode(GL_PROJECTION);       // Set projection parameters.
    gluOrtho2D(0.0, 200.0, 0.0, 150.0);
}

void lineSegment(void)
{
    glClear(GL_COLOR_BUFFER_BIT);  // Clear display window.

    glColor3f(0.0, 0.4, 0.2);      // Set line segment color to green.
    glBegin(GL_LINES);
    glVertex2i(180, 15);       // Specify line-segment geometry.
    glVertex2i(10, 145);
    glEnd();

    glFlush();     // Process all OpenGL routines as quickly as possible.
}

void main(int argc, char** argv)
{
    glutInit(&argc, argv);                         // Initialize GLUT.
    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);   // Set display mode.
    glutInitWindowPosition(50, 100);   // Set top-left display-window position.
    glutInitWindowSize(400, 300);      // Set display-window width and height.
    glutCreateWindow("An Example OpenGL Program"); // Create display window.

    init();                            // Execute initialization procedure.
    glutDisplayFunc(lineSegment);       // Send graphics to display window.
    glutMainLoop();                    // Display everything and wait.
}

4. Operation results

5. Problems and solutions

• error C2381: "exit" : redefine; __declspec(noreturn) is different

  OpenGL and C++ are not very integrated. When including, the header file of the standard C++ class library should be placed before the GLUT graphics library header file.

#include <Windows.h>
#include <glut.h>    

• The reason for the lack of OPENGL.DLL when running prompts

  opengl does not know which version of the instruction it should call now, whether it is opengl32.dll or OPENGL.dll, we only put opengl32.dll in the directory, and then add the windows.h header file in the code.

#include <Windows.h>

• Error 1 error LNK2019: unresolved external symbol imp__
  glutInitWithExit@12 referenced in function _glutInit_ATEXIT_HACK@8 D:\c++\openGL\openGL\ch3OGLexample.obj openGL

  Add #define GLUT_DISABLE_ATEXIT_HACK before glut.h header file

#define GLUT_DISABLE_ATEXIT_HACK
#include <Windows.h>
#include <glut.h>
