1. NS3 install

参考NS3 tutorial即可。

2.eclipse

2.1下载

下载地址：http://www.eclipse.org/downloads/

Eclipse IDE for C/C++ Developers

NOTE: you can know whether your ubuntu is 32-bit or 64-bit by executing the command "uname -m".

如果显示i686,你安装了32位操作系统

如果显示 x86_64，你安装了64位操作系统

2.2 jre jdk安装

2种方式，个人用的第一种，能用就行呗，不是重点：

第一种：

Installing default JRE/JDK

This is the recommended and easiest option. This will install OpenJDK 6 on Ubuntu 12.04 and earlier and on 12.10+ it will install OpenJDK 7.

Installing Java with apt-get is easy. First, update the package index:
sudo apt-get update
Then, check if Java is not already installed:
java -version
If it returns "The program java can be found in the following packages", Java hasn‘t been installed yet, so execute the following command:
sudo apt-get install default-jre
This will install the Java Runtime Environment (JRE). If you instead need the Java Development Kit (JDK), which is usually needed to compile Java applications (for exampleApache Ant, Apache Maven, Eclipse and IntelliJ IDEA execute the following command:
sudo apt-get install default-jdk
That is everything that is needed to install Java.

第二种：

Step 1: Install Java 8 (JDK 8)

Add the webupd8team java PPA repository in our system and install Oracle java8 using following set of commands.
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer
Step 2: Verify JAVA Version

After successfully installing oracle java using above step verify installed version using following command.
$ java -version

java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
Step 3: Setup JAVA Environment

Webupd8team is providing a package to set environment variables, Install this package using following command.
$ sudo apt-get install oracle-java8-set-default

2.3 Eclipse安装

解压 Eclipse

使用 Ctrl+Alt+T 打开终端并使用如下命令将 Eclipse 解压到 /opt/ 目录以供全局使用：

cd /opt/ && sudo tar -zxvf ~/下载/eclipse-*.tar.gz

解压完成后，就可以在 /opt/ 目录中看到 Eclipse 了

2.4.创建 Eclipse 快捷方式

1、在终端中执行如下命令

gksudo gedit /usr/share/applications/eclipse.desktop

2、粘贴并保存如下内容

[Desktop Entry]
Name=Eclipse 4
Type=Application
Exec=/opt/eclipse/eclipse
Terminal=false
Icon=/opt/eclipse/icon.xpm
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE;
Name[en]=Eclipse

至此，我们就将最新版本的 Eclipse Kepler 安装到 Ubuntu 14.04 中并可以使用了。

3.配置Eclipse NS3

参考2篇文章：

http://blog.sina.com.cn/s/blog_5d2054d901019vcj.html

https://www.nsnam.org/wiki/HOWTO_configure_Eclipse_with_ns-3

官方文档注意看图片，此外自己的ns3工程名字注意。

步骤：

3.1 Configure Waf Builder

3.2 Configure Debugger

3.3 Configure To Run From Eclipse

Add an external builder (Run->External Tools->External Tools Configuration) and add a new Program. Then you can configure it:

Location = your waf location (i.e. /home/x/workspace/ns-3-dev/waf)

Working Directory = your ns3 directory (i.e. /home/x/workspace/ns-3-dev/)

Arguments = --run "${string_prompt}"

Then you can run your program (with arguments) with the new created external builder.
