Your question is not very clear what it is you are actually trying to do.
This function you want to compile alone, what do you want to do with it
then? Do you want to be able to call it from other programs? Then maybe
some type of library is what you are looking for.
Do you want to be able to link it to other programs during compile time?
Then putting it in it's own .cpp may be what you're looking for.
Please explain what you are trying to achieve.

Hi Jim,
I have a large program with many function. I dont know whether the
functions are properly coded or not. So I wish to compile a single
function without any header files presented in the main. Just i wish
to check the function whether it is logically ok or not. Is there any
compiler option available in gcc/g++.
Thanks & regards...

This is pretty dicey. Sometimes programmers test functions in
standalone fashion using a "driver". That's a small main that is
compiled with the function in question, whose sole duty is to call and
receive returns from the function(s) under test. Usually different data
patterns are sent to verify the functions works per specification.
This is done sometimes when certain functions are written separately
while the rest is still be designed. It's sort of the opposite of
stubbing functions, which is where a dummy function with the correct
signature is inserted before the real one is written.
You will of course need any required headers, and the function under
test can't rely on any of the rest of the real program (other than
libraries you may be including).

Surely the functions are best tested in the environment where they are
used? You'd be better off pulling out main(), building a library with
the remainder and adding unit tests.

You put it in it's own cpp-file and then you compile that file. But I
don't think that's what you are asking for, could you please explain in
more detail what it is you are trying to accomplish?

Pl?
Put it in its own file with whatever is required to get it to compile.
