Installing Eclipse

Before beginning installation of Eclipse, it is important to ensure that you have the necessary tools. These tools can either be command line interface (CLI) or graphical programs. This guide provides instructions for both options.

Table 1: Conventions
/download/directory/	Placeholder indicating the directory to which the SDK archive will be downloaded.
/install/directory/	Placeholder indicating the directory to which Eclipse will be extracted. EMAC recommends that this directory be located somewhere within the development user's home directory.

Required Tools

• Web browser or other FTP-aware client
• Archiving tool, two options are available
  • Graphical: Ark for KDE, File Roller for GNOME
  • CLI: Tar is standard

Procedure

Install Java

Eclipse is a Java application and as such requires a Java Virtual Machine (JVM) to run. Several different JVM providers are available, including OpenJDK and Oracle Java. EMAC recommends installing OpenJDK version 6 to support the Eclipse 3.6 distribution. NEED TO TEST THIS -- CAN THEY USE VERSION 7? If you will not be doing any software development in the Java language, a Java Runtime Environment (JRE) is sufficient, otherwise, you will need to install a Java Development Kit (JDK).

Installation instructions will vary widely depending on the Linux distribution used on the development system. Most distributions, including Ubuntu and Debian, have standard packages available for OpenJDK on the distribution's software repositories. For example, to install OpenJDK6 JRE on Ubuntu or Debian, use the openjdk-6-jre package. For a JDK, the openjdk-6-jdk package can be installed instead of the JRE.

Refer to the documentation for your distribution for more information on how to install Java for your platform.

Once Java has been installed, test the installation by verifying that the java command executes properly and reports the expected version:

developer@ldc:~$ java -version

Install EMAC Eclipse

1. Download the EMAC Eclipse 3.6 distribution from the EMAC ftp site.
2. Uncompress:
   Using a graphical archiving tool: Uncompress the archive to the chosen development directory. EMAC strongly recommends that /install/directory/ is located somewhere within the developer's home directory. For assistance with extracting the archive, please see the documentation for your archiving tool.
   Using tar from the CLI: All recent versions of tar have support for performing decompression as part of the unarchiving process, allowing this to be done with one command, as shown below:

   developer@ldc:~$ cd /install/directory
   developer@ldc:~$ tar xjvf /download/directory/eclipse-3.6-Linux_EMAC-rc0.tar.bz2
   developer@ldc:~$ ls
   

   ...
   eclipse/
   ...
   

Execute Eclipse

If you are using the non-Qt version of the SDK, simply run the eclipse executable in the extracted directory to start Eclipse as shown below:

developer@ldc:~$ /install/directory/eclipse/eclipse

If you are using the Qt version of the SDK and want to use Eclipse for Qt development, you will need to run Eclipse using the emac-eclipse script included in the SDK. For example, if the SDK for your system is located at /install/directory/EMAC-OE-arm-linux-gnueabi-SDK_4.0, Eclipse could be started with the following command:

developer@ldc:~$ /install/directory/EMAC-OE-arm-linux-gnueabi-SDK_4.0

`

Next Steps

After completing the installation, continue by Configuring EMAC Eclipse.
