    remember to change the opengl version from 4.5 to 3.3 in the c++ code

    So the supported opengl version is only 2.1, but usually to use opengl core profile we need to use version >=3.3. So mesa recommends using the following line instead while executing an opengl program

    # Running opengl code in virtual box
    Sometimes, opengl codes do not run in virtual box due to different opengl implementation. for example in my system we can find out the opengl version by running the following command
    ```sh
    glxinfo | grep version
    ```
    which gives
    ```sh
    server glx version string: 1.4
    client glx version string: 1.4
    GLX version: 1.4
    Max core profile version: 3.3
    Max compat profile version: 3.3
