Install Prerequisites
|
|
=====================
|
|
|
|
To compile with ESP-IDF you need to get the following packages:
|
|
|
|
- CentOS 7::
|
|
|
|
sudo yum -y update && sudo yum install git wget flex bison gperf python3 cmake ninja-build ccache dfu-util
|
|
|
|
CentOS 7 is still supported but CentOS version 8 is recommended for a better user experience.
|
|
|
|
- Ubuntu and Debian::
|
|
|
|
sudo apt-get install git wget flex bison gperf python3 python3-pip python3-setuptools cmake ninja-build ccache libffi-dev libssl-dev dfu-util
|
|
|
|
- Arch::
|
|
|
|
sudo pacman -S --needed gcc git make flex bison gperf python-pip cmake ninja ccache dfu-util
|
|
|
|
.. note::
|
|
CMake version 3.5 or newer is required for use with ESP-IDF. Older Linux distributions may require updating, enabling of a "backports" repository, or installing of a "cmake3" package rather than "cmake".
|
|
|
|
Additional Tips
|
|
===============
|
|
|
|
Permission issues /dev/ttyUSB0
|
|
------------------------------
|
|
|
|
With some Linux distributions you may get the ``Failed to open port /dev/ttyUSB0`` error message when flashing the {IDF_TARGET_NAME}. :ref:`This can be solved by adding the current user to the dialout group<linux-dialout-group>`.
|
|
|
|
Setting up Python 3 as default for CentOS
|
|
-----------------------------------------
|
|
|
|
CentOS 7 and older is providing Python 2.7 as the default interpreter.
|
|
Python 3 is recommended instead and can be installed in old distributions as follows, or please consult the documentation of your operating system for other recommended ways to achieve this::
|
|
|
|
sudo yum -y update && sudo yum install python3 python3-pip python3-setuptools
|
|
|
|
Making Python 3 the default interpreter is possible by running::
|
|
|
|
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10 && alias pip=pip3
|
|
|
|
Setting up Python 3 as default for Ubuntu and Debian
|
|
----------------------------------------------------
|
|
|
|
Ubuntu (version 18.04 and older) and Debian (version 9 and older) are still providing Python 2.7 as the default interpreter.
|
|
Python 3 is recommended instead and can be installed in old distributions as follows, or please consult the documentation of your operating system for other recommended ways to achieve this::
|
|
|
|
sudo apt-get install python3 python3-pip python3-setuptools
|
|
|
|
Making Python 3 the default interpreter is possible by running::
|
|
|
|
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10 && alias pip=pip3
|
|
|
|
.. note::
|
|
This is system-wide change which may affect all of the applications.
|
|
|
|
Fixing broken pip on Ubuntu 16.04
|
|
=================================
|
|
|
|
Package ``python3-pip`` could be broken without possibility to upgrade it.
|
|
Package has to be removed and installed manually using script `get-pip.py <https://bootstrap.pypa.io/get-pip.py>`_.::
|
|
|
|
apt remove python3-pip python3-virtualenv; rm -r ~/.local
|
|
rm -r ~/.espressif/python_env && python get-pip.py
|
|
|
|
Python 2 deprecation
|
|
====================
|
|
|
|
Python 2 reached its `end of life <https://www.python.org/doc/sunset-python-2/>`_ and support for it in ESP-IDF will be removed soon. Please install Python 3.6 or higher. Instructions for popular Linux distributions are listed above.
|
|
