|
||||
|

|
||||
- ``BUILD_DIR_BASE``: The build directory for all objects/libraries/binaries. Defaults to ``$(PROJECT_PATH)/build``.
|
||||
- ``COMPONENT_DIRS``: Directories to search for components. Defaults to `$(IDF_PATH)/components`, `$(PROJECT_PATH)/components` and ``EXTRA_COMPONENT_DIRS``. Override this variable if you don't want to search for components in the esp-idf & project ``components`` directories.
|
||||
- ``EXTRA_COMPONENT_DIRS``: Optional list of additional directories to search for components. Components themselves are in sub-directories of these directories, this is a top-level directory containing the component directories.
|
||||
- ``COMPONENT_DIRS``: Directories to search for components. Defaults to `$(IDF_PATH)/components`, `$(PROJECT_PATH)/components`, ``$(PROJECT_PATH)/main`` and ``EXTRA_COMPONENT_DIRS``. Override this variable if you don't want to search for components in these places.
|
||||
- ``EXTRA_COMPONENT_DIRS``: Optional list of additional directories to search for components.

- ``COMPONENTS``: A list of component names to build into the project. Defaults to all components found in the COMPONENT_DIRS directories.
|
||||
- ``SRCDIRS``: Directories under the main project directory which contain project-specific "pseudo-components". Defaults to 'main'. The difference between specifying a directory here and specifying it under ``EXTRA_COMPONENT_DIRS`` is that a directory in ``SRCDIRS`` is a component itself (contains a file "component.mk"), whereas a directory in ``EXTRA_COMPONENT_DIRS`` contains component directories which contain a file "component.mk". See the `Example Project` for a concrete case of this.
|
||||
|
||||
Any paths in these Makefile variables should be absolute paths. You can convert relative paths using ``$(PROJECT_PATH)/xxx``, ``$(IDF_PATH)/xxx``, or use the Make function ``$(abspath xxx)``.
|
||||
|
||||
These variables should all be set before the line ``include $(IDF_PATH)/make/project.mk`` in the Makefile.

Component Makefiles
|
||||
-------------------
|
||||
|
||||
Each project contains one or more components, which can either be part of esp-idf or added from other component directories.
|
||||
|
||||
A component is any sub-directory that contains a `component.mk` file [#f1]_.
|
||||
A component is any directory that contains a ``component.mk`` file.

|
||||
Searching for Components
|
||||
------------------------
|
||||
|
||||
The list of directories in ``COMPONENT_DIRS`` is searched for the project's components. Directories in this list can either be components themselves (ie they contain a `component.mk` file), or they can be top-level directories whose subdirectories are components.
|
||||
|
||||
Running the ``make list-components`` target dumps many of these variables and can help debug the discovery of component directories.

Building the Bootloader
|
||||
=======================
|
||||
|
||||
The bootloader is built by default as part of "make all", or can be built standalone via "make bootloader-clean". There is also "make bootloader-list-components" to see the components included in the bootloader build.
|
||||
|
||||
The component in IDF components/bootloader is special, as the second stage bootloader is a separate .ELF and .BIN file to the main project. However it shares its configuration and build directory with the main project.
|
||||
|
||||
This is accomplished by adding a subproject under components/bootloader/subproject. This subproject has its own Makefile, but it expects to be called from the project's own Makefile via some glue in the components/bootloader/Makefile.projectbuild file. See these files for more details.
