Simple C++ Instant messenger

Question

I want to make a very simple c++ instant messenger for lan networks and internet (direct IP connect). I know little about sockets. I searched the internet, but nothing really helped. I would someone to suggest a howto/tutorial/guide. I just want to send and receive messages (in a console window, I'll create the gui later). I want it to be for both Linux and Windows. Thanks in advance!

None of the answers really helped. Thanks though. I tried Boost.Asio (it didn't compile), Qt (it works, but I do not know much about it) and the "codeproject.com" example but many problems occured. Can anybody suggest anything else? – Xerxes

what compiler/version did you use? which Boost release did you try? what were some of the "many problems" you had with Qt? will anything but a complete solution breastfed satisfy you? – Disqualification

@just somebody: I didn't say that I have problems with Qt, but with the codeproject example. I used the GNU compiler for boost, but people also confirmed that there are problems with it. – Xerxes

Answer 1

Checkout Boost.Asio. It's portable, and it's also got an example that implements a simple chat.

Keble

Thanks, I'll try that and post if I have any questions. – Xerxes

I cannot find where to download the libraries and the headers. – Xerxes

Download at boost.org/users/download. You will have to do some reading to get this working though. – Machinate

I get a linker error while trying to compile the example code in dev-c++: [Linker error] undefined reference to `_Unwind_Resume' Does anybody know how to fix it? – Xerxes

from my experience, examples (of any boost libraries i've tried) don't always compile. try a different example file. or which example it is. or something. – Disqualification

It is the only chat client example. I tried linking many different libs, but nothing worked. – Xerxes

Answer 2

check out Boost.ASIO

duplicate of the above by space cowboy. his also provides a link. – Benzoyl

@Jason - this one isn't the duplicate - it came first – Clemons

It came first.. but now link no nothing :) – Coquito

Answer 3

There's some source code here for a C/S chat application that you could probably use to get started.

Mas.

Example Code

Angora

I tried that earlier, but there is a header file I couldn't find. – Xerxes

@MaSuGaNa - I was wrong, it was a similar project of the same author which used a header I couldn't find. Is this only for windows, or I misunderstood? – Xerxes

The code looks easy enough to modify for cross platform use. If you want something already written I'd go with Boost. – Angora

Answer 4

Use boost, cross platform, under the link, straight forward example for client-server chat.
