無法設置的OpenGL

-3

以下是代碼我從一個教程了：無法設置的OpenGL

#include <GL/gl.h> 
#include <GL/glu.h> 
#include <GL/glcorearb.h> 
#include <GL/glext.h> 
#include <GL/gl_mangle.h> 
#include <GL/glu_mangle.h> 
#include <GL/GLwDrawA.h> 
#include <GL/GLwDrawAP.h> 
#include <GL/glxext.h> 
#include <GL/glx.h> 


void display() { 

    glClear(GL_COLOR_BUFFER_BIT); 
    glBegin(GL_POLYGON); 
    glColor3f(1, 0, 0); glVertex3f(-0.6, -0.75, 0.5); 
    glColor3f(0, 1, 0); glVertex3f(0.6, -0.75, 0); 
    glColor3f(0, 0, 1); glVertex3f(0, 0.75, 0); 
    glEnd(); 
    glFlush(); 
} 

int main(int argc, char** argv) { 

    glutInit(&argc, argv); 
    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB); 

    glutInitWindowPosition(80, 80); 
    glutInitWindowSize(400, 300); 
    glutCreateWindow("A Simple Triangle"); 

    glutDisplayFunc(display); 

    glutMainLoop(); 
}

我包括在/ usr/include中/ GL發現一切。我使用RHEL 6

我收到以下錯誤：

In function ‘void display()’: 
‘mglClear’ was not declared in this scope 
‘mglBegin’ was not declared in this scope

這是否意味着的東西是正確下載或我錯了，包括文件？

而是包括所有這些文件，只嘗試包括：

#include <GL/glut.h>

我沒有這個文件，不幸的是...... – user8333141

那麼，你如何期望使用'glut'的家族函數呢？我建議你安裝這個庫。 – Amadeus

首先安裝所有需要的庫

yum install mesa-libGL 
yum install mesa-libGL-devel 
yum install freeglut-devel

接下來，你需要真正正確編譯：

g++ *.cpp -lGL -lGLU -lglut

並嘗試刪除所有這些標題並將其替換爲

#include <GL/glut.h>
