Crosstool-NG (Deprecated) |
|
######################### |
|
|
|
.. warning:: |
|
|
|
``xtools`` toolchain variant is deprecated. The |
|
:ref:`cross-compile toolchain variant <other_x_compilers>` should be used |
|
when using a custom toolchain built with 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 |
