Standard Setup of Toolchain for Linux¶
To compile with ESP-IDF you need to get the following packages:
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 libffi-dev libssl-dev
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
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”.
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.
Arch Linux Users¶
To run the precompiled gdb (xtensa-esp32-elf-gdb) in Arch Linux requires ncurses 5, but Arch uses ncurses 6.
Backwards compatibility libraries are available in AUR for native and lib32 configurations:
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.
Alternatively, use crosstool-NG to compile a gdb that links against ncurses 6.
