docs: Make CMake build system default, mark GNU Make as legacy option All `-cmake` suffixes are removed Where a GNU Make option is renamed, the `-legacy` suffix is used

docs: Functional renaming commit for CMake-as-default Rename all the files which will be edited substantially in the next commit, without changing their contents Docs will not build for this ocmmit. This is done so that git doesn't decide we renamed xxx-cmake -> xxx-legacy in the next commit, which is what it will infer otherwise (and makes rebasing more of a pain than it should be)

Standard process for installing the toolchain is described :doc:`here <linux-setup>`. See :ref:`Customized Setup of Toolchain <get-started-customized-setup-legacy>` section for some of the reasons why installing the toolchain from scratch may be necessary.

Install Prerequisites
=====================
To compile with ESP-IDF you need to get the following packages:
- Ubuntu and Debian::
Docs: Update Debian & Ubuntu install prerequisites Latest versions of apt-get don't install as much packages by default as older ones. This fix adds some missing packages discovered for an OS derived from the latest stable Debian. These packages exist for older Debian derivatives as well (tested with Ubuntu 16.04 LTS). Closes https://github.com/espressif/esp-idf/issues/4480

- Arch::
sudo pacman -S --needed gcc git make ncurses flex bison gperf python2-pyserial python2-cryptography python2-future python2-pyparsing python2-pyelftools
.. 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

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 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::
TODO
Create the working directory and go into it::
mkdir -p ~/esp
cd ~/esp
Download ``crosstool-NG`` and build it:
.. include:: /_build/inc/scratch-build-code.inc
Build the toolchain::
./ct-ng xtensa-esp32-elf
./ct-ng build
chmod -R u+w builds/xtensa-esp32-elf

2019-06-24 21:26:53 -04:00
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-legacy>` to add the toolchain to your ``PATH``.
