Latest versions of apt-get don't install as much packages by default as older ones. This fix adds some missing packages discovered for an OS derived from the latest stable Debian. These packages exist for older Debian derivatives as well (tested with Ubuntu 16.04 LTS). Closes https://github.com/espressif/esp-idf/issues/4480

Install Prerequisites
|
|
=====================
|
|
|
|
To compile with ESP-IDF you need to get the following packages:
|
|
|
|
- CentOS 7::
|
|
|
|
sudo yum install git wget ncurses-devel flex bison gperf python pyserial cmake ninja-build ccache
|
|
|
|
- Ubuntu and Debian::
|
|
|
|
sudo apt-get install git wget libncurses-dev flex bison gperf python python-pip python-setuptools python-serial python-cryptography python-future python-pyparsing cmake ninja-build ccache libffi-dev libssl-dev
|
|
|
|
- Arch::
|
|
|
|
sudo pacman -S --needed gcc git make ncurses flex bison gperf python2-pyserial python2-cryptography python2-future python2-pyparsing cmake ninja ccache
|
|
|
|
.. 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".
|
|
|
|
Toolchain Setup
|
|
===============
|
|
|
|
.. include:: /_build/inc/download-links.inc
|
|
|
|
ESP32 toolchain for Linux is available for download from Espressif website:
|
|
|
|
- for 64-bit Linux:
|
|
|
|
|download_link_linux64|
|
|
|
|
- for 32-bit Linux:
|
|
|
|
|download_link_linux32|
|
|
|
|
1. Download this file, then extract it in ``~/esp`` directory:
|
|
|
|
- for 64-bit Linux:
|
|
|
|
.. include:: /_build/inc/unpack-code-linux64.inc
|
|
|
|
- for 32-bit Linux:
|
|
|
|
.. include:: /_build/inc/unpack-code-linux32.inc
|
|
|
|
.. _setup-linux-toolchain-add-it-to-path-cmake:
|
|
|
|
2. 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="$HOME/esp/xtensa-esp32-elf/bin:$PATH"
|
|
|
|
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="$HOME/esp/xtensa-esp32-elf/bin:$PATH"'
|
|
|
|
Then when you need the toolchain you can type ``get_esp32`` on the command line and the toolchain will be added to your ``PATH``.
|
|
|
|
.. note::
|
|
|
|
If you have ``/bin/bash`` set as login shell, and both ``.bash_profile`` and ``.profile`` exist, then update ``.bash_profile`` instead.
|
|
|
|
3. 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
|
|
|
|
You are looking for similar result containing toolchain's path at the beginning of displayed string::
|
|
|
|
$ printenv PATH
|
|
/home/user-name/esp/xtensa-esp32-elf/bin:/home/user-name/bin:/home/user-name/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
|
|
|
|
Instead of ``/home/user-name`` there should be a home path specific to your installation.
|
|
|
|
|
|
Permission issues /dev/ttyUSB0
|
|
------------------------------
|
|
|
|
With some Linux distributions you may get the ``Failed to open port /dev/ttyUSB0`` error message when flashing the ESP32. :ref:`This can be solved by adding the current user to the dialout group<linux-dialout-group-cmake>`.
|
|
|
|
|
|
Arch Linux Users
|
|
----------------
|
|
|
|
To run the precompiled gdb (xtensa-esp32-elf-gdb) in Arch Linux requires ncurses 5, but Arch uses ncurses 6.
|
|
|
|
Backwards compatibility libraries are available in AUR_ for native and lib32 configurations:
|
|
|
|
- https://aur.archlinux.org/packages/ncurses5-compat-libs/
|
|
- https://aur.archlinux.org/packages/lib32-ncurses5-compat-libs/
|
|
|
|
Before installing these packages you might need to add the author's public key to your keyring as described in the "Comments" section at the links above.
|
|
|
|
Alternatively, use crosstool-NG to compile a gdb that links against ncurses 6.
|
|
|
|
|
|
Next Steps
