Custom CMake Toolchains
|
|
#######################
|
|
|
|
To use a custom toolchain defined in an external CMake file, export the
|
|
following environment variables:
|
|
|
|
.. code-block:: console
|
|
|
|
# Linux and macOS
|
|
export ZEPHYR_TOOLCHAIN_VARIANT=<toolchain name>
|
|
export TOOLCHAIN_ROOT=<path to toolchain>
|
|
|
|
# Windows
|
|
set ZEPHYR_TOOLCHAIN_VARIANT=<toolchain name>
|
|
set TOOLCHAIN_ROOT=<path to toolchain>
|
|
|
|
You can also set them as CMake variables when generating a build
|
|
system for a Zephyr application, like so:
|
|
|
|
.. code-block:: console
|
|
|
|
cmake -DZEPHYR_TOOLCHAIN_VARIANT=... -DTOOLCHAIN_ROOT=...
|
|
|
|
Zephyr will then include the toolchain cmake file located in:
|
|
``<path to toolchain>/cmake/toolchain/<toolchain name>.cmake``.
