Package Manager
|
|
===============
|
|
|
|
To set up the toolchain from scratch, rather than :doc:`downloading a pre-compiled toolchain<macos-setup>`, you will need to install either the 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
|
|
|
|
See :ref:`Customized Setup of Toolchain <get-started-customized-setup>` section for some of the reasons why installing the toolchain from scratch may be necessary.
|
|
|
|
Install Prerequisites
|
|
=====================
|
|
|
|
- install pip::
|
|
|
|
sudo easy_install pip
|
|
|
|
- install pyserial::
|
|
|
|
pip install --user pyserial
|
|
|
|
- install CMake & Ninja build:
|
|
|
|
- If you have HomeBrew, you can run::
|
|
|
|
brew install cmake ninja
|
|
|
|
- If you have MacPorts, you can run::
|
|
|
|
sudo port install cmake ninja
|
|
|
|
Compile the Toolchain from Source
|
|
=================================
|
|
|
|
- Install dependencies:
|
|
|
|
- with MacPorts::
|
|
|
|
sudo port install gsed gawk binutils gperf grep gettext wget libtool autoconf automake make
|
|
|
|
- with homebrew::
|
|
|
|
brew install gnu-sed gawk binutils gperftools gettext wget help2man libtool autoconf automake make
|
|
|
|
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::
|
|
|
|
mkdir -p ~/esp
|
|
ln -s /Volumes/ctng ~/esp/ctng-volume
|
|
|
|
Go into the newly created directory::
|
|
|
|
cd ~/esp/ctng-volume
|
|
|
|
Download ``crosstool-NG`` and build it:
|
|
|
|
.. include-build-file:: inc/scratch-build-code.inc
|
|
|
|
Build the toolchain::
|
|
|
|
./ct-ng xtensa-{IDF_TARGET_TOOLCHAIN_NAME}-elf
|
|
./ct-ng build
|
|
chmod -R u+w builds/xtensa-{IDF_TARGET_TOOLCHAIN_NAME}-elf
|
|
|
|
Toolchain will be built in ``~/esp/ctng-volume/crosstool-NG/builds/xtensa-{IDF_TARGET_TOOLCHAIN_NAME}-elf``. To use it, you need to add ``~/esp/ctng-volume/crosstool-NG/builds/xtensa-{IDF_TARGET_TOOLCHAIN_NAME}-elf/bin`` to ``PATH`` environment variable.
