ESP-IDF build process relies on a number of tools: cross-compiler toolchains, CMake build system, and others.

Installing the tools using an OS-specific package manager (like apt, yum, brew, etc.) is the preferred method when the required version of the tool is available. This recommendation is reflected in the Getting Started guide. For example, on Linux and macOS it is recommended to install CMake using an OS package manager.

The ESP-IDF build process relies on a number of tools: cross-compiler toolchains, CMake build system, and others.
|

However, some of the tools are IDF-specific and are not available in OS package repositories. Furthermore, different versions of ESP-IDF require different versions of the tools to operate correctly. To solve these two problems, ESP-IDF provides a set of scripts for downloading and installing the correct versions of tools, and exposing them in the environment.

- ``idf-env.json`` — user install options (targets, features) are stored in this file. Targets are selected chip targets for which tools are installed and kept up-to-date. Features determine the Python package set which should be installed. These options will be discussed later.

:idf_file:`tools/idf_tools.py` script bundled with ESP-IDF performs several functions:
|
||||
The :idf_file:`tools/idf_tools.py` script bundled with ESP-IDF performs several functions:
|
||||
|
||||
* ``install``: Download the tool into ``${IDF_TOOLS_PATH}/dist`` directory, extract it into ``${IDF_TOOLS_PATH}/tools/TOOL_NAME/VERSION``.
|
||||
* ``install``: Download the tool into the ``${IDF_TOOLS_PATH}/dist`` directory and extract it into ``${IDF_TOOLS_PATH}/tools/TOOL_NAME/VERSION``.
|
||||
|
||||
``install`` command accepts the list of tools to install, in ``TOOL_NAME`` or ``TOOL_NAME@VERSION`` format. If ``all`` is given, all the tools (required and optional ones) are installed. If no argument or ``required`` is given, only the required tools are installed.

The ``install`` command accepts the list of tools to install in the ``TOOL_NAME`` or ``TOOL_NAME@VERSION`` format. If ``all`` is given, all the tools, including required and optional ones, are installed. If no argument or ``required`` is given, only the required tools are installed.
|
||||
|
||||
* ``download``: Similar to ``install`` but doesn't extract the tools. An optional ``--platform`` argument may be used to download the tools for the specific platform.
|
||||
|
||||
* ``export``: Lists the environment variables which need to be set to use the installed tools. For most of the tools, setting ``PATH`` environment variable is sufficient, but some tools require extra environment variables.

The environment variables can be listed in either ``shell`` or ``key-value`` formats, which can be set using the ``--format`` parameter:
|

|

- ``export`` optional parameters:
|
||||
|
||||
- ``--unset`` Creates statement that unset some global variables, so the environment gets to the state it was before calling ``export.{sh/fish}``.
|
||||
- ``--add_paths_extras`` Adds extra ESP-IDF-related paths of ``$PATH`` to ``${IDF_TOOLS_PATH}/esp-idf.json``, which is used to remove global variables when the active ESP-IDF environment is deactivated. Example: While processing ``export.{sh/fish}`` script, new paths are added to global variable ``$PATH``. This option is used to save these new paths to the ``${IDF_TOOLS_PATH}/esp-idf.json``.
|
||||
- ``--unset``: Creates a statement that unsets specific global variables and restores the environment to its state before calling ``export.{sh/fish}``.
|

- ``--add_paths_extras``: Adds extra ESP-IDF-related paths of ``$PATH`` to ``${IDF_TOOLS_PATH}/esp-idf.json``, which is used to remove global variables when the active ESP-IDF environment is deactivated. For example, while processing the ``export.{sh/fish}`` script, if new paths are added to the global variable ``$PATH``, this option saves these new paths to the ``${IDF_TOOLS_PATH}/esp-idf.json`` file.

* ``check``: For each tool, checks whether the tool is available in the system path and in ``IDF_TOOLS_PATH``.

|
||||
* ``install-python-env``: Create a Python virtual environment in the ``${IDF_TOOLS_PATH}/python_env`` directory (or directly in the directory set by the ``IDF_PYTHON_ENV_PATH`` environment variable) and install there the required Python packages. An optional ``--features`` argument allows one to specify a comma-separated list of features to be added or removed. Feature that begins with ``-`` will be removed and features with ``+`` or without any sign will be added. Example syntax for removing feature ``XY`` is ``--features=-XY`` and for adding ``--features=+XY`` or ``--features=XY``. If both removing and adding options are provided with the same feature, no operation is performed. For each feature a requirements file must exist. For example, feature ``XY`` is a valid feature if ``${IDF_PATH}/tools/requirements/requirements.XY.txt`` is an existing file with a list of Python packages to be installed. There is one mandatory ``core`` feature ensuring core functionality of ESP-IDF (build, flash, monitor, debug in console). There can be an arbitrary number of optional features. The selected list of features is stored in ``idf-env.json``. The requirement files contain a list of the desired Python packages to be installed and ``espidf.constraints.*.txt`` downloaded from https://dl.espressif.com and stored in ``${IDF_TOOLS_PATH}`` the package version requirements for a given ESP-IDF version. Althought it is not recommended, the download and use of constraint files can be disabled with the ``--no-constraints`` argument or setting the ``IDF_PYTHON_CHECK_CONSTRAINTS`` environment variable to ``no``.
|
||||
* ``install-python-env``: Creates a Python virtual environment in the ``${IDF_TOOLS_PATH}/python_env`` directory or directly in the directory set by the ``IDF_PYTHON_ENV_PATH`` environment variable, and install the required Python packages there.
|

|
||||
* ``check-python-dependencies``: Checks if all required Python packages are installed. Packages from ``${IDF_PATH}/tools/requirements/requirements.*.txt`` files selected by the feature list of ``idf-env.json`` are checked with the package versions specified in the ``espidf.constraints.*.txt`` file. The constraint file is downloaded with ``install-python-env`` command. The use of constraints files can be disabled similarly to the ``install-python-env`` command.
|
||||
* An optional ``--features`` argument allows one to specify a comma-separated list of features to be added or removed.
|
||||
|
||||
* ``uninstall``: Print and remove tools, that are currently not used by active ESP-IDF version.

If both removing and adding options are provided with the same feature, no operation is performed.
