Install Prerequisites
|
||
|
|
=====================
|
||
|
|
|
||
|
|
ESP-IDF will use the version of Python installed by default on Mac OS.
|
||
|
|
|
||
|
|
- install pip::
|
||
|
|
|
||
|
|
sudo easy_install pip
|
||
|
|
|
||
|
|
- install pyserial::
|
||
|
|
|
||
|
|
sudo pip install pyserial
|
||
|
|
|
||
|
|
- install CMake & Ninja build:
|
||
|
|
|
||
|
|
- If you have HomeBrew_, you can run::
|
||
|
|
|
||
|
|
brew install cmake ninja
|
||
|
|
|
||
|
|
- If you have MacPorts_, you can run::
|
||
|
|
|
||
|
|
sudo port install cmake ninja
|
||
|
|
|
||
|
|
- Otherwise, consult the CMake_ and Ninja_ home pages for Mac OS installation downloads.
|
||
|
|
|
||
|
|
- It is strongly recommended to also install ccache_ for faster builds. If you have HomeBrew_, this can be done via ``brew install ccache`` or ``sudo port install ccache`` on MacPorts_.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
If an error like this is shown during any step::
|
||
|
|
|
||
|
|
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
|
||
|
|
|
||
|
|
Then you will need to install the XCode command line tools to continue. You can install these by running ``xcode-select --install``.
|
||
|
|
|
||
|
|
Toolchain Setup
|
||
|
|
===============
|
||
|
|
|
||
|
|
ESP32 toolchain for macOS is available for download from Espressif website:
|
||
|
|
|
||
|
|
https://dl.espressif.com/dl/xtensa-esp32-elf-osx-1.22.0-80-g6c4433a-5.2.0.tar.gz
|
||
|
|
|
||
|
|
Download this file, then extract it in ``~/esp`` directory::
|
||
|
|
|
||
|
|
mkdir -p ~/esp
|
||
|
|
cd ~/esp
|
||
|
|
tar -xzf ~/Downloads/xtensa-esp32-elf-osx-1.22.0-80-g6c4433a-5.2.0.tar.gz
|
||
|
|
|
||
|
|
.. _setup-macos-toolchain-add-it-to-path-cmake:
|
||
|
|
|
||
|
|
The toolchain will be extracted into ``~/esp/xtensa-esp32-elf/`` directory.
|
||
|
|
|
||
|
|
To use it, you will need to update your ``PATH`` environment variable in ``~/.profile`` file. To make ``xtensa-esp32-elf`` available for all terminal sessions, add the following line to your ``~/.profile`` file::
|
||
|
|
|
||
|
|
export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin
|
||
|
|
|
||
|
|
Alternatively, you may create an alias for the above command. This way you can get the toolchain only when you need it. To do this, add different line to your ``~/.profile`` file::
|
||
|
|
|
||
|
|
alias get_esp32="export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin"
|
||
|
|
|
||
|
|
Then when you need the toolchain you can type ``get_esp32`` on the command line and the toolchain will be added to your ``PATH``.
|
||
|
|
|
||
|
|
Log off and log in back to make the ``.profile`` changes effective. Run the following command to verify if ``PATH`` is correctly set::
|
||
|
|
|
||
|
|
printenv PATH
|
||
|
|
|
||
|
|
|
||
|
|
