Chat Server in Netwide Assembly

A simple chat server and client implemented entirely in Assembly for x86-64 Linux.

Chat means cat in French, hence the project name Miaou echoing the sound a cat makes in French.

Prerequisites

• NASM assembler
• GNU ld linker
• Make

Directory layout

inc/malloc/     Custom malloc implementation
inc/utils/      Utility routines
inc/boeuf/      Dynamic buffers library
inc/miaou/      Chat protocol definitions
src/        Assembly sources (.s)
build/      Output directory for executables

Build

Use the Makefile to assemble and link executables. Specify the target via PROGRAM_NAME.

• Build the client:

  make PROGRAM_NAME=client

• Build the server:

  make PROGRAM_NAME=server

Executables are placed in the build/ directory:

build/client
build/server

Run

1. Start the server in one terminal:

   ./build/server

2. In another terminal, start a client:

   ./build/client

3. Multiple clients can connect to the server to chat.
