I am using my own graphics software with OPENGL. For linking with library, I am using -lMesaGL among others. Since this is
not available any more, I replaced with -lGL -lGLU. It is
compiling and it is also a Window of specific size. It is
writing text of specified length, font and color. But it is
not doing the background_color and it is not allowing any
graphics color to draw shapes.
