Hey. there above it writes some errors that two are not included:

 #error gl.h included before glew.h #error glext.h included before glew.h

Try to do so in the operating system.

 #include <stdio.h> #include <GL/glext.h> #include <GL/gl.h> #include <GL/glut.h> #include <GL/freeglut.h> #include <GL/glew.h> #include <GL/glu.h> ...

But there is further error:

 error: unknown type name 'GLenum'

What has not yet been delivered

PS Try to compile this code:

 #include <stdio.h> #include <GL/glew.h> #include <GL/glut.h> #include <GL/freeglut.h> #include <GL/glu.h> void display(void){ glClear(GL_COLOR_BUFFER_BIT); // ΠžΡ‡ΠΈΡΡ‚ΠΊΠ° экрана glClearColor(0.0,0.0,0.0,0.0); gluOrtho2D(0.0,0.0,0.0,0.0); glBegin(GL_TRIANGLES); glVertex2f(0.0,0.0); glVertex2f(1.0,0.0); glVertex2f(0.0,1.0); glVertex2f(1.0,1.0); glVertex2f(0.0,-1.0); glVertex2f(-1.0,0.0); glVertex2f(-1.0,-1.0); glEnd(); glFlush(); } extern int main(int arg,char** arc){ glutInit(&arg,arc); glutInitDisplayMode(GLUT_SINGLE|GLUT_RGBA); glutCreateWindow("Simp"); glutDisplayFunc(display); //glutMouseFunc(mouse);//ΠΊΠΎΠΎΡ€Π΄ΠΈΠ½Π°Ρ‚Ρ‹ ΠΌΡ‹ΡˆΠΈ функция glutMainLoop(); return 0; }
