<para> + Part of the Yocto Project development solution is an Application Development + Toolkit (ADT). + The ADT provides you with a custom-built, cross-development + platform suited for developing a

Cross-Development Toolchain</title> + + <para> + The + <ulink url='&YOCTO_DOCS_DEV_URL;#cross-development-toolchain'>Cross-Development Toolchain</ulink> + consists of a cross-compiler, cross-linker, and cross-debugger + that are used to develop user-space applications for targeted + hardware. + This toolchain is created either by running the ADT Installer + script, a toolchain installer script, or through a + <ulink url='&YOCTO_DOCS_DEV_URL;#build-directory'>Build Directory</ulink> + that is based on your Metadata configuration or extension for + your targeted device. + The cross-toolchain

generating + binaries that run on the target architecture. + The sysroot is based on the target root filesystem image that is built by + the OpenEmbedded build system and uses the same Metadata configuration + used to build the cross-toolchain. + </para> + </section> + + <section id='eclipse-overview'> + <title>Eclipse Yocto Plug-in</title> + + <para> + The Eclipse IDE is a popular development environment and it fully supports + development using the Yocto Project. + When you install and configure the Eclipse Yocto Project Plug-in into + the Eclipse IDE, you maximize your Yocto Project experience. + Installing and configuring the Plug-in results in an environment that + has extensions specifically designed to let you more easily develop software. + These extensions allow for cross-compilation, deployment, and execution of + your output into a QEMU emulation session. + You can also perform cross-debugging and profiling. + The environment also supports a suite of tools that allows you to perform + remote profiling, tracing, collection of power data, collection of + latency data, and collection of performance data. + </para> + + <para> + For information about the application development workflow that uses the Eclipse + IDE and for a detailed example of how to install and configure the Eclipse + Yocto Project Plug-in, see the + "<ulink
