hi,,
thankx for response.. but the link u sent me is a normal file... can u help me out with some make files so that i can modify my file....

If your application does not run in the background automatically (fork/setsid), then you have to tell the shell to run the app in the background for you. Make uses "sh" as the default shell. It uses "&" to run things in the background.

>> "./server& " should not be used.
Why? That's how you tell the shell to run it in the background...

hi,

The binary 'server' should be a daemon binary.
(ie)
The binary should run as back-ground process by default.
(i.e, without specifying '&' symbol)....

This is what my question was exactly....

>> The binary 'server' should be a daemon binary.
How to do that was given in post #2.
Call fork(), exit() and setsid().
