3.2. Setting Up the Cross-Development Environment

Before you can develop using the cross-toolchain, you need to set up the cross-development environment by sourcing the toolchain's environment setup script. If you used the ADT Installer or hand-installed cross-toolchain, then you can find this script in the directory you chose for installation. For this release, the default installation directory is /opt/poky/. If you installed the toolchain in the Build Directory, you can find the environment setup script for the toolchain in the Build Directory's tmp directory.

Be sure to run the environment setup script 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 architecture. For example, the toolchain environment setup script for a 64-bit IA-based architecture installed in the default installation directory would be the following:

     /opt/poky//environment-setup-x86_64-poky-linux
