Standard Setup of Toolchain for Linux


Install Prerequisites

To compile with ESP-IDF you need to get the following packages:

  • CentOS 7:

    sudo yum install git wget flex bison gperf python cmake ninja-build ccache dfu-util
  • Ubuntu and Debian:

    sudo apt-get install git wget flex bison gperf python python-pip python-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


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-S2. This can be solved by adding the current user to the dialout group.

Setting up Python 3 as default for Ubuntu and Debian

Ubuntu and Debian are still providing Python 2.7 as the default interpreter but some required packages may be missing for newer distributions. Python 3 is recommended and can be installed as follows:

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


This is system-wide change which may affect all of the applications.

Next Steps

To carry on with development environment setup, proceed to Step 2. Get ESP-IDF.
