developer@ldc:~$	Prompt and commands to be run on a development machine that will run compliation tasks.
root@emac-oe:~#	Prompt and commands to be run on a target machine.

Before beginning installation of the SDK, it is important to prepare the development system with the tools necessary to get the job done. These tools can either be command line interface (CLI) or graphical utilities. Both options are described in this guide.

Required tools

• Web browser (recommended Mozilla Firefox, Gnuzilla Icecat, KDE Konqueror)
• Archiving tool. There are two options available:
  • Graphical tools (Ark for KDE, File Roller for GNOME)
  • CLI tool (tar is standard)
• dialog required for CLI use of SDK (see the developer's website).

Recommendations

The following are some recommended install opations

• The SDK should be kept in the user's home directory. For example,

# /path/to/sdk/ might expand to something like 
/home/user_name/cust_software/

To clarify, this is the location where EMAC-OE-arm-linux-gnueabi-SDK_XX.YY/ will end up.

• The default SDK root folder name should be kept at its default name since this preserves the version information for the EMAC OE SDK.

Procedure

1. Download the SDK. The latest version can be found on the public EMAC FTP site. Be sure to download the SDK that matches the architecture of your target system. Contact EMAC if unsure.

2. Uncompress the SDK.

   • Using a graphical archiving tool, uncompress the archive files to the chosen development directory. If you need assistance with this, please see the documentation for your graphical archiving tool.

   • Alternatively, you can uncompress the archive from the CLI using tar:

      developer@ldc:~$ cd /target/directory
      developer@ldc:~$ bzip2 -cd /download/directory/EMAC-OE-arm-linux-gnuabi-SDK_XX.YY.rZZ.tar.bz2 | tar xvf -
     

     This will produce a subdirectory within the target directory:

      developer@ldc:~$ ls
     

      ...
      EMAC-OE-arm-linux-gnueabi-SDK_XX.YY/
      ...
     

Next Steps

Once the EMAC SDK is installed, the next step is to Configuring_EMAC_OE_SDK.
