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
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-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
Note
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.
