- Install Prerequisites
- =====================
- To compile with ESP-IDF you need to get the following packages:
- - CentOS 7::
- 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
- - Arch::
- 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
- .. 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<linux-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:
- - https://aur.archlinux.org/packages/ncurses5-compat-libs/
- - https://aur.archlinux.org/packages/lib32-ncurses5-compat-libs/
- 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.
- Next Steps
- ==========
- To carry on with development environment setup, proceed to :ref:`get-started-get-esp-idf`.
