***************************************

Setup Toolchain for Mac OS from Scratch
 | 
						|
***************************************
 | 
						|
 | 
						|
Install Prerequisites
 | 
						|
=====================
 | 
						|
 | 
						|
- install pip::
 | 
						|
 | 
						|
    sudo easy_install pip
 | 
						|
 | 
						|
.. note::
 | 
						|
 | 
						|
    ``pip`` will be used later for installing :ref:`the required Python packages <get-started-get-packages>`.
 | 
						|
 | 
						|
Compile the Toolchain from Source
 | 
						|
=================================
 | 
						|
 | 
						|
- Install dependencies:
 | 
						|
 | 
						|
  - Install either MacPorts_ or homebrew_ package manager. MacPorts needs a full XCode installation, while homebrew only needs XCode command line tools.
 | 
						|
    
 | 
						|
    .. _homebrew: https://brew.sh/
 | 
						|
    .. _MacPorts: https://www.macports.org/install.php
 | 
						|
 | 
						|
  - with MacPorts::
 | 
						|
 | 
						|
        sudo port install gsed gawk binutils gperf grep gettext wget libtool autoconf automake
 | 
						|
 | 
						|
  - with homebrew::
 | 
						|
 | 
						|
        brew install gnu-sed gawk binutils gperftools gettext wget help2man libtool autoconf automake
 | 
						|
 | 
						|
Create a case-sensitive filesystem image::
 | 
						|
 | 
						|
    hdiutil create ~/esp/crosstool.dmg -volname "ctng" -size 10g -fs "Case-sensitive HFS+"
 | 
						|
 | 
						|
Mount it::
 | 
						|
 | 
						|
    hdiutil mount ~/esp/crosstool.dmg
 | 
						|
 | 
						|
Create a symlink to your work directory::
 | 
						|
 | 
						|
    cd ~/esp
 | 
						|
    ln -s /Volumes/ctng crosstool-NG
 | 
						|
 | 
						|
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-macos-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`.
