Can any help me out what these exactly means ??

Sounds not to be a C-queston. More likely it's a compiler/linker issue.
You should read more carefully your compiler/linker manual about 'how
to make a library' or 'how to make an executable' depending what you
want to do exactly.

Hi Ranjeet,

Frankly, It's only one error.

I have a quesition. What type of application do you want to build?
executive or library?

It seems like you are building a library but you choosed wrong
application type.

There are no portable C programs in freestanding environments.
For example, in a freestanding environment there is no way to
predict the name of the program startup function.

i've tried to build some code which don't have a main function.
yes ,it proves u're right.
but i heard someone said that the c program sometimes can run without a
main function .then what is that?

Really? I wonder, if a program doesn't have `main', is it UB, or CV?
Which rule is violated?

The important word in Ben's answer was "portable".

Non-portable programs may run without a main() function if there is an
alternative in their environment (like WinMain() in Windows, for
instance).
