Install eclipse ns3 in ubuntu 14.04

1. NS3 install

參考NS3 tutorial便可。

2.eclipse

2.1下載

下載地址：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".

若是顯示i686,你安裝了32位操做系統

若是顯示 x86_64，你安裝了64位操做系統

2.2 jre jdk安裝

2種方式，我的用的第一種，能用就行唄，不是重點：

第一種：

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.

第二種：

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安裝

解壓 Eclipse

使用 Ctrl+Alt+T 打開終端並使用以下命令將 Eclipse 解壓到 /opt/ 目錄以供全局使用：

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

解壓完成後，就能夠在 /opt/ 目錄中看到 Eclipse 了

2.4.建立 Eclipse 快捷方式

一、在終端中執行以下命令

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

二、粘貼並保存以下內容

[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，咱們就將最新版本的 Eclipse Kepler 安裝到 Ubuntu 14.04 中並能夠使用了。

3.配置Eclipse NS3

參考2篇文章：

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

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

官方文檔 注意看圖片，此外本身的ns3工程名字注意。

步驟：

3.1 Configure Waf Builder

3.2 Configure Debugger

3.3 Configure To Run From Eclipse

1. 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.

4.結束語

最後再說一下，若是在命令行中帶參數運行程序時，須要將程序名和參數使用雙引號一併包含，如：
./waf --run "RPS 4"  (說明：RPS是程序名，"4"是參數）

直接輸入 程序名 和那些參數設置便可

如：myfirst –XX=XX

不要加引號
