Once you have the SDK installed, you must run the SDK environment setup script before you can actually use it. This setup script resides in the directory you chose when you installed the SDK. For information on where this setup script can reside, see the "Obtaining the SDK" Appendix.
Before running the script, be sure it is the one that matches the
architecture for which you are developing.
Environment setup scripts begin with the string
"environment-setup
" and include as part of
their name the tuned target architecture.
For example, the command to source a setup script for an IA-based
target machine using i586 tuning and located in the default SDK
installation directory is as follows:
$ source /opt/poky/2.5/environment-setup-i586-poky-linux
When you run the setup script, the same environment variables are defined as are when you run the setup script for an extensible SDK. See the "Running the Extensible SDK Environment Setup Script" section for more information.
