How to Install Emacs 24.4 in Ubuntu:

At the moment of writing this tutorial, there’s no PPA repository that contains Emacs 24.4. Fortunately, it’s not hard to build it from the source tarball. I’ve done it successfully in 64-bit Ubuntu 14.04 LTS. Below steps will show you how:

1. If have the old Emacs 24.3 installed, you may first remove it from Ubuntu Software Center so that you can install the new version over it.

2. Press Ctrl+Alt+T on keyboard to open terminal, or open it from the Unity Dash.

Open Terminal to run commands

3. Run command below to install the build-essential:

sudo apt-get install build-essential

4. Install the required dependencies:

sudo apt-get build-dep emacs24

While the installing process, you’ll be asked to configure the Postfix.

5. Now download Emacs 24.4 from its official FTP download page.

cd ~/Downloads && tar -xf emacs-24.4.tar.* && cd emacs-24.4

7. Finally compile the package by running commands below one by one.

1.) To get better game experience, you may first install graphics driver for your video card:

  • For Intel graphics, you’re good to go with the default open-source driver.

2.) For Java, you can either install OpenJDK Java 7 from Ubuntu Software Center or install Oracle Java from PPA.

To install OpenJDK Java 7, click the button below to bring up Ubuntu Software Center and click the install button.

Click to Install OpenJDK 7

To install Oracle Java, see this post or just run commands below one by one in terminal:

sudo apt-add-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java8-installer

3.) Once Java Runtime is installed, download the Minecraft.jar file from:

Minecraft Download Page

4.) Make the Minecraft.jar file executable.

To do so, right-click on the file in Nautilus browser and go to its Properties windows -> Permissions tab and finally check the box where it says “Allow executing file as program”.
