3rd Party Toolchains
|
|
####################
|
|
|
|
A "3rd party toolchain" is an officially supported toolchain provided by an
|
|
external organization. Several of these are available.
|

.. _toolchain_gnuarmemb:

|

GNU ARM Embedded
|
|
****************
|
|
|
|
#. Download and install a `GNU ARM Embedded`_ build for your operating system
|
|
and extract it on your file system.
|
|
|
|
.. warning::
|
|
|
|
Do not install the toolchain into a path with spaces. On
|
|
Windows, we'll assume you install into the directory
|
|
:file:`C:\\gnu_arm_embedded`.
|
|
|
|
.. warning::
|
|
|
|
On macOS Catalina or later you might need to :ref:`change a security
|
|
policy <mac-gatekeeper>` for the toolchain to be able to run from the
|
|
terminal.
|
|
|
|
#. :ref:`Set these environment variables <env_vars>`:
|
|
|
|
- Set :envvar:`ZEPHYR_TOOLCHAIN_VARIANT` to ``gnuarmemb``.
|
|
- Set :envvar:`GNUARMEMB_TOOLCHAIN_PATH` to the toolchain installation
|
|
directory.
|
|
|
|
#. To check that you have set these variables correctly in your current
|
|
environment, follow these example shell sessions (the
|
|
:envvar:`GNUARMEMB_TOOLCHAIN_PATH` values may be different on your system):
|
|
|
|
.. code-block:: console
|
|
|
|
# Linux, macOS:
|
|
$ echo $ZEPHYR_TOOLCHAIN_VARIANT
|
|
gnuarmemb
|
|
$ echo $GNUARMEMB_TOOLCHAIN_PATH
|
|
/home/you/Downloads/gnu_arm_embedded
|
|
|
|
# Windows
|
|
> echo %ZEPHYR_TOOLCHAIN_VARIANT%
|
|
gnuarmemb
|
|
> echo %GNUARMEMB_TOOLCHAIN_PATH%
|
|
C:\gnu_arm_embedded
|
|
|
|
.. warning::
|
|
|
|
On macOS, if you are having trouble with the suggested procedure, there is an unofficial package on brew that might help you.
|
|
Run ``brew install gcc-arm-embedded`` and configure the variables
|
|
|
|
- Set :envvar:`ZEPHYR_TOOLCHAIN_VARIANT` to ``gnuarmemb``.
|
|
- Set :envvar:`GNUARMEMB_TOOLCHAIN_PATH` to the brew installation directory (something like ``/usr/local``)

Intel oneApi Toolkits
|
|
*********************
|
|
|
|
#. Download `Intel oneAPI Base Toolkit
|
|
<https://software.intel.com/content/www/us/en/develop/tools/oneapi/all-toolkits.html>`_
|
|
|
|
#. Assuming the toolkit is installed in ``/opt/intel/oneApi``, set environment
|
|
using::
|
|
|
|
export ONEAPI_TOOLCHAIN_PATH=/opt/intel/oneapi
|
|
source $ONEAPI_TOOLCHAIN_PATH/compiler/latest/env/vars.sh
|
|
|
|
To setup the complete oneApi environment, use::
|
|
|
|
source /opt/intel/oneapi/setvars.sh
|
|
|
|
The above will also change the python environment to the one used by the
|
|
toolchain and might conflict with what Zephyr uses.
|
|
|
|
#. Set :envvar:`ZEPHYR_TOOLCHAIN_VARIANT` to ``oneApi``.

DesignWare ARC MetaWare Development Toolkit (MWDT)
|
|
**************************************************
|
|
|
|
#. You need to have `ARC MWDT
|
|
<https://www.synopsys.com/dw/ipdir.php?ds=sw_metaware>`_ installed on your
|
|
host.
|
|
|
|
#. :ref:`Set these environment variables <env_vars>`:
|
|
|
|
- Set :envvar:`ZEPHYR_TOOLCHAIN_VARIANT` to ``arcmwdt``.
|
|
- Set :envvar:`ARCMWDT_TOOLCHAIN_PATH` to the toolchain installation
|
|
directory. MWDT installation provides :envvar:`METAWARE_ROOT` so simply set
|
|
:envvar:`ARCMWDT_TOOLCHAIN_PATH` to ``$METAWARE_ROOT/../`` (Linux)
|
|
or ``%METAWARE_ROOT%\..\`` (Windows)
|
|
|
|
#. To check that you have set these variables correctly in your current
|
|
environment, follow these example shell sessions (the
|
|
:envvar:`ARCMWDT_TOOLCHAIN_PATH` values may be different on your system):
|
|
|
|
.. code-block:: console
|
|
|
|
# Linux:
|
|
$ echo $ZEPHYR_TOOLCHAIN_VARIANT
|
|
arcmwdt
|
|
$ echo $ARCMWDT_TOOLCHAIN_PATH
|
|

|
|
|

Crosstool-NG
|
|
************
|
|
|
|
You can build toolchains from source code using crosstool-NG.
|
|
|
|
#. Follow the steps on the crosstool-NG website to `prepare your host
|
|
<http://crosstool-ng.github.io/docs/os-setup/>`_.
|
|
|
|
#. Follow the `Zephyr SDK with Crosstool NG instructions
|
|
<https://github.com/zephyrproject-rtos/sdk-ng/blob/master/README.md>`_ to
|
|
build your toolchain. Repeat as necessary to build toolchains for multiple
|
|
target architectures.
|
|
|
|
You will need to clone the ``sdk-ng`` repo and run the following command:
|
|
|
|
.. code-block:: console
|
|
|
|
./go.sh <arch>
|
|
|
|
.. note::
|
|
|
|
Currently, only i586 and Arm toolchain builds are verified.
|
|
|
|
#. :ref:`Set these environment variables <env_vars>`:
|
|
|
|
- Set :envvar:`ZEPHYR_TOOLCHAIN_VARIANT` to ``xtools``.
|
|
- Set :envvar:`XTOOLS_TOOLCHAIN_PATH` to the toolchain build directory.
|
|
|
|
#. To check that you have set these variables correctly in your current
|
|
environment, follow these example shell sessions (the
|
|
:envvar:`XTOOLS_TOOLCHAIN_PATH` values may be different on your system):
|
|
|
|
.. code-block:: console
|
|
|
|
# Linux, macOS:
|
|
$ echo $ZEPHYR_TOOLCHAIN_VARIANT
|
|
xtools
|
|
$ echo $XTOOLS_TOOLCHAIN_PATH
