This is a step-by-step alternative to running the :doc:`ESP-IDF Tools Installer <windows-setup>` for the CMake-based build system. Installing all of the tools by hand allows more control over the process, and also provides the information for advanced users to customize the install.
|
|
|
|
To quickly setup the toolchain and other tools in standard way, using the ESP-IDF Tools installer, proceed to section :doc:`windows-setup`.
|
|
|
|
.. note::
|
|
The GNU Make based build system requires the MSYS2_ Unix compatibility environment on Windows. The CMake-based build system does not require this environment.
|
|
|
|
.. _get-esp-idf-windows-command-line:

|
|
|
Get ESP-IDF
|
|
===========
|
|
|
|
.. note::
|
|
|
|
Previous versions of ESP-IDF used the **MSYS2 bash terminal** command line. The current cmake-based build system can run in the regular **Windows Command Prompt** which is used here.
|
|
|
|
If you use a bash-based terminal or PowerShell, please note that some command syntax will be different to what is shown below.
|
|
|
|
Open Command Prompt and run the following commands:
|
|
|
|
.. include:: /_build/inc/git-clone-windows.inc
|
|
|
|
ESP-IDF will be downloaded into ``%userprofile%\esp\esp-idf``.
|
|
|
|
Consult :doc:`/versions` for information about which ESP-IDF version to use in a given situation.
|
|
|
|
.. include:: /_build/inc/git-clone-notes.inc
|
|
|
|
.. note::
|
|
|
|
Do not miss the ``--recursive`` option. If you have already cloned ESP-IDF without this option, run another command to get all the submodules::
|
|
|
|
cd esp-idf
|
|
git submodule update --init
|
|
|
|
|
|
Tools
|
|
=====
|
|
|
|
cmake
|
|
^^^^^
|
|
|
|
Download the latest stable release of CMake_ for Windows and run the installer.
|
|
|
|
When the installer asks for Install Options, choose either "Add CMake to the system PATH for all users" or "Add CMake to the system PATH for the current user".
|
|
|
|
Ninja build
|
|
^^^^^^^^^^^
|
|
|
|
.. note::
|
|
Ninja currently only provides binaries for 64-bit Windows. It is possible to use CMake and ``idf.py`` with other build tools, such as mingw-make, on 32-bit windows. However this is currently undocumented.
|
|
|
|
Download the ninja_ latest stable Windows release from the (`download page <ninja-dl>`_).
|
|
|
|
The Ninja for Windows download is a .zip file containing a single ``ninja.exe`` file which needs to be unzipped to a directory which is then `added to your Path <add-directory-windows-path>`_ (or you can choose a directory which is already on your Path).
|
|
|
|
|
|
Python
|
|
^^^^^^
|
|
|
|
Download the latest Python_ for Windows installer, and run it.
|
|
|
|
The "Customise" step of the Python installer gives a list of options. The last option is "Add python.exe to Path". Change this option to select "Will be installed".
|
|
|
|
Once Python is installed, open a Windows Command Prompt from the Start menu and run the following command::
|
|
|
|
pip install --user pyserial
|
|
|
|
MConf for IDF
|
|
^^^^^^^^^^^^^
|
|
|
|
Download the configuration tool mconf-idf from the `kconfig-frontends releases page <mconf-idf>`_. This is the ``mconf`` configuration tool with some minor customizations for ESP-IDF.
|
|
|
|
This tool will also need to be unzipped to a directory which is then `added to your Path <add-directory-windows-path>`_.
|
|
|
|
Toolchain Setup
|
|
===============
|
|
|
|
.. include:: /_build/inc/download-links.inc
|
|
|
|
Download the precompiled Windows toolchain:
|
|
|
|
|download_link_win32|
|
|
|
|
Unzip the zip file to ``C:\Program Files`` (or some other location). The zip file contains a single directory ``xtensa-esp32-elf``.
|
|
|
|
Next, the ``bin`` subdirectory of this directory must be `added to your Path <add-directory-windows-path>`_. For example, the directory to add may be ``C:\Program Files\xtensa-esp32-elf\bin``.
|
|
|
|
.. note::
|
|
If you already have the MSYS2 environment (for use with the "GNU Make" build system) installed, you can skip the separate download and add the directory ``C:\msys32\opt\xtensa-esp32-elf\bin`` to the Path instead, as the toolchain is included in the MSYS2 environment.
|
|
|
|
|
|
.. _add-directory-windows-path:
|
|
|
|
Adding Directory to Path
|
|
========================
|
|
|
|
To add any new directory to your Windows Path environment variable:
|
|
|
|
Open the System control panel and navigate to the Environment Variables dialog. (On Windows 10, this is found under Advanced System Settings).
|
|
|
|
Double-click the ``Path`` variable (either User or System Path, depending if you want other users to have this directory on their path.) Go to the end of the value, and append ``;<new value>``.
|
|
|
|
|
|
Next Steps
|
|
==========
|
|
|
|
To carry on with development environment setup, proceed to :ref:`get-started-set-up-tools`.
