the program i have pasted below -- might be missing some lines as i
removed
few lines ( comments ) while pasting here , the actual program is at

I compiled using command rvcemcabrp@rvcemcabrp-laptop:~/Desktop/opengl$ g++ rotating_cube_display_open_gl.C -lm -lGL -lGLU -lglut
then i tried this

such
operation) Major opcode of failed request: 143 (GLX) Minor opcode of failed request: 19 (X_GLXQueryServerString) Serial number of failed request: 12 Current serial number in output stream: 12 rvcemcabrp@rvcemcabrp-laptop:~/Desktop/opengl$
i want solution for any of the following problems
------------------ this is for one of the labs for BE ( computer
science
students -- VI semester ) Implement the following programs in C / C++
- Program to recursively subdivide a tetrahedron to from 3D
Sierpinski
gasket. The number of recursive steps is to be specified by the
user.
Program to implement Liang-Barsky line clipping algorithm.
Program to draw a color cube and spin it using OpenGLtransformation
matrices.
- Program to create a house like figure and rotate it about a
given
fixed point using OpenGL functions.
- Program to implement the Cohen-Sutherland line-clipping
algorithm.
Make provision to specify the input line, window for clipping
and view
port for displaying the clipped image.
- Program to create a cylinder and a parallelepiped by
extruding a
circle and
quadrilateral respectively. Allow the user to specify thecircle and
the quadrilateral.
7 Program, using OpenGL functions, to draw a simple shaded
scene
consisting of a tea pot on a table. Define suitably the position
and
properties of the light source along with the properties of the
properties
of the surfaces of the solid object used in the scene.
- Program to draw a color cube and allow the user to move the
camera
suitably to experiment with perspective viewing. Use OpenGL
functions.
- Program to fill any given polygon using scan-line area
filling
algorithm. (Use appropriate data structures.) 3. Program to display a set of values { fij } as a rectangular
mesh.
Part B
Develop a suitable Graphics package to implement the skills learnt
in the
theory and the exercises indicated in Part A. Use the OpenGL.
i have ran opengl progs :) i ran it as gcc -lglut <filename.c> -o <output file name >

Just check whether you have the code correct or not, as i can run it perfectly here, i tried the code out from the links you gave, i tried the spinning cube one, and also check whether you have correct header files and packages.*From the program i can say that freeglut is missing, some of the API's used use some functions of freeglut *. If you still couldn't get it right, mail me the code you are using, verbatim.And there is no need of doing -lm -lGL -lGLU , only lglut will do for the spinning cube program.Btw I am a student of CS 6th sem :)
