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 pyserial python-pyelftools cmake ninja-build ccache
  • Ubuntu and Debian:

    sudo apt-get install git wget flex bison gperf python python-pip python-setuptools python-serial python-click python-cryptography python-future python-pyparsing python-pyelftools cmake ninja-build ccache libffi-dev libssl-dev
  • Arch:

    sudo pacman -S --needed gcc git make flex bison gperf python2-pip python2-pyserial python2-click python2-cryptography python2-future python2-pyparsing python2-pyelftools cmake ninja ccache


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

Next Steps

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