********************************************* Standard Setup of Toolchain for Linux ********************************************* :link_to_translation:`zh_CN:[中文]` Install Prerequisites ===================== To compile with ESP-IDF you need to get the following packages: - CentOS 7:: sudo yum -y update && sudo yum install git wget flex bison gperf python3 python3-pip python3-setuptools cmake ninja-build ccache CentOS 7 is still supported but CentOS version 8 is recommended for a better user experience. - Ubuntu and Debian:: sudo apt-get install git wget flex bison gperf python3 python3-pip python3-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 .. 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`. Fixing broken pip on Ubuntu 16.04 ================================= Package ``python3-pip`` could be broken without possibility to upgrade it. Package has to be removed and installed manually using script `get-pip.py `_.:: apt remove python3-pip python3-virtualenv; rm -r ~/.local rm -r ~/.espressif/python_env && python get-pip.py Python 2 deprecation ==================== Python 2 reached its `end of life `_ and support for it in ESP-IDF will be removed soon. Please install Python 3.6 or higher. Instructions for popular Linux distributions are listed above.
