Overview
This document takes you through the OpenRG Software Development Kit (SDK) installation process, and assists you in solving potential installation difficulties.
1.1. What Does the SDK Provide?
• A fully featured, 30-day evaluation SDK for Gateway developers. • Available for all hardware platforms:
• All Intel-based IXP425 platforms • ADI AD6834 • Broadcom ASUS BCM6348 • Conexant CX8620X • Freescale MPC8272ADS • Storlink Centroid • Broadcom GTWX5803
• A gateway emulation (UML), which enables you to compile and run a virtual gateway on your PC without a hardware platform.
• Includes an installation script (install.sh), which installs the following components: • Toolchain according to your chosen platform.
Overview
• License files (<*>.lic).
• Key features source code and the Linux kernel.
• Tools to help you work in the OpenRG environment such as compiler, linker, assembler, debugger and others.
1.2. Software and Hardware
Requirements
Developing with OpenRG requires the following setup: • A Residential Gateway or development platform
• A host PC running one of the following versions of the Linux operating system: • Debian 3.1 or higher
• Mandrake 8.1 or higher • Redhat 7.3 or higher • Ubuntu
Note: When compiling OpenRG on Ubuntu, change the soft-link /bin/sh to point to /bin/bash. OpenRG's UML distribution cannot be compiled on Ubuntu.
• A text editor that supports tags, such as VI or Emacs.
• The following minimum hardware requirements for the host PC: • 1.6GHz CPU
• 256MB RAM
• 1.5GB free disk space • 2 network cards
Overview
1.3. Windows Users
For Windows users, the SDK can also be used on a virtual Linux, running on top of Windows. These emulators run the Linux as a Windows application. The following are links to download virtual Linux over Windows:
• coLinux - a free and open source emulation: http://www.colinux.org
• VMWare - both a commercial version and a 30-day evaluation are available: http:// www.vmware.com

Installation Process
Note: In order to install the SDK, you must have certain standard Linux packages installed. If a package is missing during the installation process, you will be prompted to install it to complete the process. The Linux packages you will need are the
standard gcc, make and libc packages for your Linux distribution. If you can compile "hello world", you are ready to install the OpenRG SDK.
To install the development environment on your host PC perform the following: 1. Download the SDK from http://www.jungo.com/openrg/download.html.
2. Extract the SDK archive, usually rg_sdk_install.tgz:
$ tar xvzf rg_sdk_install.tgz
3. Change the directory to rg_sdk_install and run the install script.
$ cd rg_sdk_install $ ./install.sh
4. The install script is interactive. Follow its instructions:
1. If prompted, select the target architecture to install. Enter 'y' to confirm the
installation. The script will fetch and extract source packages and toolchains from the Internet. These actions may take some time, depending on your Internet connection speed.
2. If interested, change the default directory of the development tree when prompted to enter the installation directory. For example, .
Installation Process
Have the root password ready, you will need to provide it to the script when installing the toolchain.
5. After a successful installation, instructions for compiling the image appear on the screen (refer to chapterchap_compile).
Note: After installing the SDK, most OpenRG configurations will require:
Bison - GNU Project parser generator. Flex - Contains a utility for generating programs that perform pattern-matching on text.

Compiling an Image
1. Change the directory to where you installed the OpenRG development tree, for example:
$ cd ~/rg.4_8_11/rg
2. Execute the following command to automatically configure the development tree:
make config DIST=<platform-specific distribution> LIC=<license file path>
The "platform-specific distribution" part correlates with your board's model. The license is provided with your distribution.
3. To build the image files, execute:
make
4. The compilation process will produce openrg.img, which is a binary that can be
downloaded and burnt using OpenRG's 'flash load' CLI command. You can find the image in the build subdirectory of the OpenRG development tree (i.e. rg.4_8_11/rg/build). The factory settings can be found in the build/pkg/main subdirectory (i.e. rg.4_8_11/rg/build/

Burning an Image
Burn the image to the board according to the installation guide of your chosen platform. You can download installation guides for each of the platforms from: http://www.jungo.com/ openrg/install.html .

Uninstall Process
In order to uninstall the SDK, follow these steps: 1. Remove sources:
$ rm -rf rg-<version>
Specify the version of OpenRG you wish to remove. 2. Become a super-user:
$ su
Provide an administrator password.
3. Remove toolchains, which are copied by the install script to /usr/local/openrg:

Troubleshooting
6.1. I Have a Missing Package
The following is an example of an error message that can appear during your installation process:
CRITICAL: Could not find package rg-build_4.0.30_src.ejpkg jpkg failed to download/extract required package.
In this case, the rg-build_4.0.30_src.ejpkg package could not be found. If you encounter a similar message, please:
1. Make sure you are connected to the Internet.
2. If this error still appears, contact Jungo's support team at [email protected], and we will provide you with the missing package.
6.2. I Have a Compilation Problem
If you encounter compilation problems:
1. Make sure you are able to compile "hello world".
2. If "hello world" compiles and the SDK does not, please contact Jungo's support team at
6.3. My Evaluation License has Expired
Troubleshooting
1. You may extend your evaluation for an additional 30-day period, by contacting Jungo's support team at [email protected].
2. If you wish to purchase a commercial license, please contact your local representative, which you can locate at http://www.jungo.com/contact.html , or write directly to
6.4. How do I Perform Multiple
Installations of OpenRG on a Single
Download?
1. Install OpenRG once on one computer. The OpenRG packages will be cached in ~/ .jpkg_cache/*.ejpkg.
2. Copy all the *.ejpkg files to a file server in your own network, or to a local computer to which you would like to install.
3. Set JPKG_SEARCH_PATH to the path of the OpenRG packages: • If the server is a Web server:
$ export JPKG_SEARCH_PATH=<path to HTTP server>
• If the server is a file server:
$ export JPKG_SEARCH_PATH=<path to file server>
