If you only want to build for one board, add the name of the board configuration for your application on a new line. Make sure to follow these steps in order. This section describes some of what you can do in your CMakeLists.txt. The final zephyr.elf image contains both the application and the kernel libraries. This file is the entry point, or top level, of the build system.
Application CMakeLists.txtĮvery application must have a CMakeLists.txt file. The PUBLIC keyword could however be useful when modifying the include paths of a target library. In this case, using PUBLIC would cause libraries that link with app to also include the source file src/main.c, behavior that we surely do not want. Using the keyword PUBLIC would modify how other libraries that link with app are built. The PRIVATE keyword indicates that we are modifying the internals of how the library is being built. In the above CMakeLists.txt, an existing library target named app is configured to include the source file src/main.c. Library targets have source code, that is added through CMakeLists.txt build scripts like this: target_sources(app PRIVATE src/main.c)
#SEGGER EMBEDDED STUDIO INCLUDE PATH CODE#
All source code that goes into a Zephyr build does so by being included in a library target, even application code. For application developers, the library target is the most important to understand. A target can be an executable, a library, or a generated file. Zephyr uses CMake’s concept of a ‘target’ to organize the build. The build scripts can detect some of these situations and reconfigure automatically, but there are cases when this must be done manually. However, after certain changes, the configuration step must be executed again before building. These build scripts can recompile the application without involving CMake following most code changes. After configuration, you begin the build stage by executing the generated build scripts. After configuration is finished, CMake has an internal model of the Zephyr build, and can generate build scripts that are native to the host platform.Īll the CMakefile information can be found at Zephyr Project Documentation.ĬMake supports generating scripts for several build systems, but only Ninja and Make are tested and supported by Zephyr. During configuration, the CMakeLists.txt build scripts are executed. CMake is used to build your application together with the Zephyr kernel.
