Thanks Norman for your valuable suggestion.... :)
We are also planned to follow the same procedure...:)

>    I.e., does it depend on fork/exeve, how does it communicate with
>    other parts of the system (Unix domain sockets, binder, etc.)?
>    Look if those code portions are somehow abstracted so that they

>    try to disable all optional features like optimizations. The
>    goal should be to get a version of the runtime that is as simple
>    as possible.
> 2. Port the library dependencies to Genode following this guide:
>    While porting the libraries, I would stick with the base-linux
>    platform, which enables you to use GDB for debugging. So the
>    development can happen at a fast pace.
> 3. Once all libraries needed by ART are ported, it is time to
>    port ART itself. The steps outlined in the above linked porting
>    guide might be very helpful. I would keep using base-linux at this
>    point. The goal should be to run a minimal-complexity example
>    (like a hello-world program) using a run script.
> 4. Now that a simple example is running on base-linux, proceed to
>    run the same scenario on one of the microkernels. I think that
>    when you managed to reach this stage, the further steps will
>    become apparent automatically.
