Using the Application Development Toolkit

The ADT is an SDK installation script that installs the following for Poky-supported hardware platforms:

• A prebuilt cross-compilation toolchain, as explained previously

• A sysroot that matches the core-image-sato target image

• The QEMU emulator

• Other development user space tools used for system profiling (these will be discussed in the following chapters)

Getting ready

To install the ADT, you can choose either of the following options:

• Download a precompiled tarball from the Yocto project downloads site with the following command:

  $ wget http://downloads.yoctoproject.org/releases/yocto/yocto- 1.7.1/adt-installer/adt_installer.tar.bz2
  

• Build one using your Yocto build directory.

The ADT installer is an automated script to install precompiled Yocto SDK components, so it will be the same whether you download the prebuilt version or you build one yourself.

You can then configure it before running it to customize the installation.
