# Introduction

If you haven’t known what is Clang yet, have a look at this article Clang on Wikipedia

# Requirements & Installation

First, you have to install AutoComplete for Emacs. You can install it using Emacs Package Manager. The next step is to install Yasnippet. This is not compulsory but is encouraged for better experiments. You can also install it using Emacs Package Manager. To see how to get Autocomplete and Yasnippet to work together, see this article Config Yasnippet and Autocomplete on Emacs.

Before installing this package, you should also check whether your system has installed “clang” or not via this command clang --version in terminal. If you get nothing from terminal, which means you haven’t installed “clang” yet. If you are on Ubuntu, you can try those 2 commands sudo apt-get update, sudo apt-get install clang and check it again. Until clang works fine, you can continue the following instructions.

If your computer has satisfied those requirements, now you can start installing Clang autocomplete. In fact, it’s a source for Autocomplete plugin, that’s why we need Autocomplete installed.

You need to clone the auto-complete-clang source from github. I advise you to clone it into your .emacs.d directory. After that, add this to your .emacs or init.el (if you use the modern style of .emacs) to load it to emacs’ load-path and activate auto-complete-clang.

Finally, bind it to a key binding for using. I bind it to C-` so that it do not conflict with autocomplete or yasnippet
