Cross-compilation

We have already learned that the environment for embedded development consists of two systems: the build system, where you write and build code, and the host system, which runs the code.

We now have two virtualized environments set up:

• Ubuntu Linux in a Docker container, which will be our build system
• QEMU running Raspbian Linux, which will be our host system

In this recipe, we will set up the cross-compilation tools required to build Linux applications for the ARM platform and build a simple Hello, world! application to test the setup.

Getting ready

To set up the cross-compilation toolkit, we will need to use Ubuntu Linux, which we set up in the Setting up the build system in a Docker container...
