Ran into ncurses5 dependency issue on popOS stub section for covering libncurses 5 workarounds on distributions that need it, when only Arch was mentioned it was too easy to skip over the section Merges https://github.com/espressif/esp-idf/pull/3236

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 python-pyelftools 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-click python-cryptography python-future python-pyparsing python-pyelftools cmake ninja-build ccache
|
|
|
|
- Arch::
|
|
|
|
sudo pacman -S --needed gcc git make ncurses flex bison gperf python2-pip python2-pyserial python2-click python2-cryptography python2-future python2-pyparsing python2-pyelftools 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".
|
|
|
|
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 ESP32. :ref:`This can be solved by adding the current user to the dialout group<linux-dialout-group>`.
|
|
|
|
ncurses 5 dependency
|
|
--------------------
|
|
|
|
To run the precompiled gdb (xtensa-esp32-elf-gdb) in Linux requires ncurses 5, but some newer distributions only provide ncurses 6 by default.
|
|
|
|
Consult your distribution's documentation to see if ncurses 5 libraries are available. Alternatively, use crosstool-NG to compile a gdb that links against ncurses 6.
|
|
|
|
For Arch Linux users, ncurses 5 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.
|
|
|
|
Next Steps
|
|
==========
|
|
|
|
To carry on with development environment setup, proceed to :ref:`get-started-get-esp-idf`.
