for these packages.

Setup Linux Toolchain from Scratch
**********************************
The following instructions are alternative to downloading binary toolchain from Espressif website. To quickly setup the binary toolchain, instead of compiling it yourself, backup and proceed to section :doc:`linux-setup`.
Install Prerequisites
=====================
To compile with ESP-IDF you need to get the following packages:
- Ubuntu and Debian::
sudo apt-get install git wget make libncurses-dev flex bison gperf python python-pip python-setuptools python-serial
- Arch::
sudo pacman -S --needed gcc git make ncurses flex bison gperf python2-pyserial
.. note::
Some older (pre-2014) Linux distributions may use ``pyserial`` version 2.x which is not supported by ESP-IDF.
In this case please install a supported version via ``pip`` as it is described in section
:ref:`get-started-get-packages`.
Compile the Toolchain from Source
=================================
- Install dependencies:
- CentOS 7::
sudo yum install gawk gperf grep gettext ncurses-devel python python-devel automake bison flex texinfo help2man libtool
- Ubuntu pre-16.04::
sudo apt-get install gawk gperf grep gettext libncurses-dev python python-dev automake bison flex texinfo help2man libtool
- Ubuntu 16.04::
sudo apt-get install gawk gperf grep gettext python python-dev automake bison flex texinfo help2man libtool libtool-bin
- Debian 9::
sudo apt-get install gawk gperf grep gettext libncurses-dev python python-dev automake bison flex texinfo help2man libtool libtool-bin
- Arch::
TODO
Download ``crosstool-NG`` and build it::
cd ~/esp
git clone -b xtensa-1.22.x https://github.com/espressif/crosstool-NG.git
cd crosstool-NG
./bootstrap && ./configure --enable-local && make install
Build the toolchain::
./ct-ng xtensa-esp32-elf
./ct-ng build
chmod -R u+w builds/xtensa-esp32-elf
Toolchain will be built in ``~/esp/crosstool-NG/builds/xtensa-esp32-elf``. Follow :ref:`instructions for standard setup <setup-linux-toolchain-add-it-to-path>` to add the toolchain to your ``PATH``.
Next Steps
==========
To carry on with development environment setup, proceed to section :ref:`get-started-get-esp-idf`.
