[omniORB] Corba Dependencies on Operating system ?

[swapna mudavath]

Sir,

I am working for a team developing our own Board support package and
customizing linux for our platform(portng linux on RISC processor).
We want corba middle ware over Operating system

I have few enquiries regarding the dependencies

      1) Are there any specific dependencies  of corba implementation on
                           a) Board support package
                           b) Real time operating system

      2)In particular does Omniorb have operating system dependencies

      3) Are there any calls the Operating System must provide for corba?
