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`.
To compile with ESP-IDF you need to get the following packages:
Ubuntu and Debian:
sudo apt-get install gcc git wget make libncurses-dev flex bison gperf python python-pip python-setuptools python-serial python-cryptography python-future python-pyparsing
Arch:
sudo pacman -S --needed gcc git make ncurses flex bison gperf python2-pyserial python2-cryptography python2-future python2-pyparsing
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 or newer:
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:

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
.
To carry on with development environment setup, proceed to section :ref:`get-started-get-esp-idf`.
