Hey guys,
recently i've tried to compile this command line email program

I get the error:
cannot find -lobjc
ld returned 1 exit status

Here's my code.

Any Help Appreciated.

Did you not see the C section? It's right below the C++ one.
But it seems that your problem is that you're trying to link a library that does not exist. If you need it for this program, you'll have to install it.

Anuragcoder, do you mind if I ask where you're getting all this source code from?

The problems you're having and the questions you're asking don't seem to match with the level of the code you're pasting.

First with the syntax highlighting, then with the press enter twice, now with this network code. Also, I see before you claim to have written a full cashier interface.

These are simple problems and errors that someone of the calibre that can write (or is expected to write) programs of that nature should not be having an issue with.

The problem is in the winsock library. When you call functions from that library, you get linker error.
Write a simple 2-3 line code calling a function from winsock library to check if your library is installed correctly

Thanks a lot abhimanipal.
and as for ketsuekiame........please...errors are made by even greatest of the great.
i do not have time that's all

and as for enter twice code,
i better suggest using a delimiter.
and as for syntax highlighting....
i better use colorer(or atleast its kernel)

However, greatness is measured by the smallest of its details.

And here's a detail explained to you: "Since you don't have time, we do not have time for you"
