For this project, we are assuming that Linux has been installed on the target SBC, and that the drivers for the hardware functionality, such as the microphone and audio output, have been installed and configured.
Since we use the Qt framework for this project, all dependencies there should be met as well. This means that the shared libraries should be present on the system on which the resulting binary for the project will be run. The Qt framework can be obtained via the package manager of the OS, or via the Qt website at http://qt.io/.
In Chapter 10, Developing Embedded Systems with Qt, we will look at developing on embedded platforms with Qt in more detail. This chapter will briefly touch upon the use of Qt APIs.
Depending on whether we want to compile the application directly on the SBC or on our development PC, we might have to install the compiler...
