This includes all CMake configuration output. Idf.py fullclean will delete the entire “build” directory contents. Cleaning doesn’t delete CMake configuration output and some other files. Idf.py clean will “clean” the project by deleting build output files from the build directory, forcing a “full rebuild” the next time the project is built. By default, the build tool is automatically detected but it can be explicitly set by passing the -G option to idf.py.īuilding is incremental so if no source files or configuration has changed since the last build, nothing will be done. Run the main build tool ( Ninja or GNU Make). Run CMake as necessary to configure the project and generate build files for the main build tool. The sub-directory build is used to hold build output, although this can be changed with the -B option. This can involve multiple steps:Ĭreate the build directory if needed. Idf.py build will build the project found in the current directory. Idf.py menuconfig runs the “menuconfig” tool to configure the project. Here are a summary of the most useful ones:

Type idf.py -help for a full list of commands. Older style projects with a Makefile will not work with idf.py. Idf.py should be run in an ESP-IDF “project” directory, ie one containing a CMakeLists.txt file.

The getting started guide contains a brief introduction to how to set up idf.py to configure, build, and flash projects. It manages the following tools:ĬMake, which configures the project to be builtĪ command line build tool (either Ninja build or GNU Make) The idf.py command line tool provides a front-end for easily managing your project builds. The toolchain should be installed in the system command line PATH. The toolchain for compilation is not part of the project. This allows the IDF framework to be decoupled from your project. Instead it is standalone, and linked to the project via the IDF_PATH environment variable which holds the path of the esp-idf directory. At the moment, ESP-IDF supports only one target, esp32. “Target” is the hardware for which an application is built. Some are provided by ESP-IDF itself, others may be sourced from other places.

“components” are modular pieces of standalone code which are compiled into static libraries (.a files) and linked into an app. A single project will usually build two apps - a “project app” (the main executable, ie your custom firmware) and a “bootloader app” (the initial bootloader program which launches the project app).

A single project contains exactly one project configuration.Īn “app” is an executable which is built by ESP-IDF. This configuration file is modified via idf.py menuconfig to customise the configuration of the project. “Project configuration” is held in a single file called sdkconfig in the root directory of the project. Using Third-Party CMake Projects with ComponentsĪ “project” is a directory that contains all the files and configuration to build a single “app” (executable), as well as additional supporting elements such as a partition table, data/filesystem partitions, and a bootloader.Fully Overriding The Component Build Process.Requirements in the build system implementation.

Feel free to remove CMakeCache.txt and CMakeFiles. Message(FATAL_ERROR 'You cannot build in a source directory (or any directory with a CMakeLists.txt file). To add this folder to your CMake path: set(CMAKE_MODULE_PATH '$/CMakeLists.txt' LOC_PATH) An set of some common helpers is at /CLIUtils/cmake.

You often want a cmake folder, with all of your helper modules. Use add_subdirectory to add a subdirectory containing a CMakeLists.txt. That's also why there is a directory for your project inside the include directory. This is because you should be able to copy the contents of the include directory to /usr/include or similar directly (except for configuration headers, which I go over in another chapter), and not have any extra files or cause any conflicts. Notice a few things already apparent the CMakeLists.txt files are split up over all source directories, and are not in the include directories. You'll also sometime see a python folder for python bindings, or a cmake folder for helper CMake files, like Find.cmake files. tests/, and the application folder may be called something else (or not exist for a library-only project). The names are not absolute you'll see contention about test/ vs.

Keep from muddling and complicating your build.įirst, this is what your files should look like when you start if your project is creatively called project, with a library called lib, and a executable called app: - project.

Easily read other projects following the same patterns,.

This is based on convention, but will help you: I'm going to tell you how to structure the directories in your project.
