Setup Toolchain for Mac OS from Scratch
|
|
***************************************
|
|
|
|
Install Prerequisites
|
|
=====================
|
|
|
|
- install pip::
|
|
|
|
sudo easy_install pip
|
|
|
|
- install pyserial::
|
|
|
|
sudo pip install pyserial
|
|
|
|
|
|
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``.
