    Building the mesh stack

    The mesh library and example applications can be built using either CMake or SEGGER Embedded Studio.

    Using CMake provides the possiblity to build both for host (unit tests) and target, while SEGGER Embedded Studio provides a way of quickly getting the example code up and running with full debug capability.

    Before you continue, check Installing the mesh toolchain ro instructions on setting up the development environment for mesh.

    可以使用CMake或SEGGER嵌入式Studio构建网格库和示例应用程序。使用CMake提供了为主机(单元测试)和目标构建的可能性,而SEGGER嵌入式Studio提供了一种快速获取示例代码并运行完全调试功能的方法。在继续之前,请检查安装网格工具链的指令,以设置网格的开发环境。

    Building with SEGGER Embedded Studio

    To build with SEGGER Embedded Studio, open one of the project files located in the examples/ folder, e.g.,examples/light_switch/client/light_switch_client_nrf52832_xxAA_s132_5_0_0.emProject.

    To compile the example, go to Build -> Build light_switch_client_nrf52832_xxAA_s132_5.0.0. After the compilation is complete, first erase the device using Target -> Erase all and run the example with Debug -> Go. This will download the matching SoftDevice and the compiled example and start the debugger. When the download is complete select Debug -> Goagain to start the code execution.

    Building with CMake

    From About CMake:

    CMake is an extensible, open-source system that manages the build process in an operating system and in a compiler-independent manner.

    In other words, CMake does not build from the source directly, but generates the native build tool files (for example, a set of Makefiles or a build.ninja configuration). Which build tool to target is controlled via the -G argument, for example: -G Ninja-G "Unix Makefiles" and many more. CMake can generate IDE project files for IDEs such as Eclipse as well. However, this guide only targets Ninja and GNU Make.

    Important: All examples built by the CMake-generated build system do not include the SoftDevice as part of the generated HEX files. Therefore, the SoftDevice must already be present on the device before flashing the HEX file for the example mesh application.

    Generating build files

    Important: In this section, we are genating build files for the Ninja build tool. On Debian/Linux, you may drop the -G Ninja argument as the default generator is for Unix Makefiles and use the make command instead of ninja.

    Good practice is to create a build folder in the root directory for the mesh stack repository, where all artifacts generated by the Ninja build system are stored, such as:

    mesh-btle $ mkdir build
    mesh-btle $ cd build
    

    Before you can build with Ninja, you must generate the correct build files with CMake:

    build$ cmake -G Ninja -DTOOLCHAIN=gccarmemb -DPLATFORM=nrf52840_xxAA ..
    

    Based on the options given in the command line arguments, four main parameters are set:

    1. TOOLCHAIN
      • gccarmemb for the GNU ARM Embedded toolchain
      • armcc for the Keil ARMCC toolchain
      • clang for the Clang compiler (with GNU ARM Embedded assembler and linker)
    2. PLATFORM
      • nrf51422_xxAC
      • nrf52832_xxAA
      • nrf52840_xxAA
    3. BOARD: valid board combination based on platform type
    4. SOFTDEVICE: valid SoftDevice based on platform type

    The build system will ensure a valid BOARD and SOFTDEVICE for each given platform. Calling cmake -G Ninja .. will default to thenrf52832_xxAA platform with the S132 v5.0.0 SoftDevice and the GNU ARM Embedded Toolchain.

    After the Ninja build files are generated, running ninja will build all the targets (examples and libraries). Documentation can be built with ninja doc. If you have PC-Lint installed, the sources can be linted using the ninja lint command. To see a list of available build targets, run the following command:

    build $ ninja help
    

    To build a specific target from this list, run, for example, ninja mesh_core_nrf52840_xxAA if the current platform is nrf52840_xxAA.

    CMake generates Ninja build files in the folder in which CMake is run (but not in any of its subfolders), so all targets must be built from that directory. In other words, in-directory building is not supported and running ninja in one of the example folders will result in an error message generated by the Ninja build system.

    However, the mesh stack can be built from its root directory as well, which will place the generated artifacts in the folder where the source files are kept:

    mesh-btle $ cmake -G Ninja    # Generate build files
    mesh-btle $ ninja
    

    By default, CMake is configured to build for target using the GNU ARM Embedded toolchain. To build with ARMCC instead, setTOOLCHAIN to armcc:

    mesh-btle $ mkdir build && cd build         # Create a build directory
    build $ cmake -G Ninja -DTOOLCHAIN=armcc .. # Generate build files
    build $ ninja
    

    Generating SEGGER Embedded Studio project files

    Warning: The generator will overwrite any existing projects, please back up existing projects before running the generator.

    It is possible to generate SEGGER Embedded Studio project files using the CMake build system. With the optionGENERATE_SES_PROJECTS enabled, CMake will generate a SEGGER Embedded Studio project based on the current settings. For example, to generate a project for nrf51422_xxAC using the S110 SoftDevice, run CMake in your build directory like this:

    cmake -G Ninja -DGENERATE_SES_PROJECTS=ON -DPLATFORM=nrf51422_xxAC -DSOFTDEVICE=s110_8.0.0 ..
    

    Useful CMake command line options

    CMake allows you to generate project files in release or debug configurations. To do so, use the -DCMAKE_BUILD_TYPE option:

    build $ cmake -DCMAKE_BUILD_TYPE=Release .. # Generates build files in release mode
    build $ cmake -DCMAKE_BUILD_TYPE=Debug ..   # Generates build files in debug mode
    

    The default build type is Debug if the CMake project is a Git repository (contains a .git directory), otherwise it is set toRelWithDebInfo.

    Building the documentation

    To build all documentation (API documentation and internal documentation), call the build system with the target doc.

    build $ ninja doc
    

    The Doxygen documentation is generated in <build folder>/doc/offline/html.

    Unit test build (host)

    The nRF5 SDK for Mesh contains a set of unit tests that verify module behavior. These unit tests run on the host system (i.e. PC, not the nRF5 device), and are built with GCC. See Installing the mesh toolchain for toolchain requirements.

    The nRF5 SDK for Mesh depends on two frameworks for unit testing:

    • Unity is the unit testing framework that is used for running the tests.
    • CMock is used by the unit tests to generate mocks.

    Note that an installation of Git is required to download these modules.

    CMock bundles Unity as a submodule, thus in the same directory as the nRF5 SDK for Mesh, make sure to clone the CMock repository recursively:

    $ git clone https://github.com/ThrowTheSwitch/CMock.git --recursive cmock
    

    The directory structure should now look like this:

    .
    +-- cmock/
    +-- nrf5_sdk_for_bluetooth_mesh/
    

    Enter the nrf5_sdk_for_bluetooth_mesh directory, and make a new build directory, e.g. build_host:

    nrf5_sdk_for_bluetooth_mesh $ mkdir -p build_host && cd build_host
    

    To build for host, so that the unit tests can be run, set the option BUILD_HOST to ON and provide the path to CMock using theCMOCK_ROOT option. Note that all paths given to CMake must use forward slashes ('/') as directory separators.

    build_host $ cmake -G Ninja -DBUILD_HOST=ON -DCMOCK_ROOT=<dir/cmock> ..
    

    If a different version of Unity from the one included as a submodule in CMock is wanted, this can be specified by passing -DUNITY_ROOT=<dir/unity> to CMake. Note that the two paths can be set permanently with environmental variables (UNITY_ROOTand CMOCK_ROOT), and CMake is set up to look for CMock in the directory above the nrf5_sdk_for_bluetooth_mesh, so if the instructions above have been followed, both these variables are redundant.

    Build all the unit tests with ninja:

    build_host $ ninja
    

    To run the tests, run ctest (bundled with CMake) or call ninja test in the build directory.

    build_host $ ctest # Run all unit tests
