Look at the preprocessor output
*******************************
To save preprocessor output when using GCC-based toolchains, add
``-save-temps=obj`` to the ``EXTRA_CFLAGS`` CMake variable. For example, to
build :ref:`hello_world` with west with this option set, use:
To save preprocessor output files, enable the
:kconfig:option:`CONFIG_COMPILER_SAVE_TEMPS` option. For example, to build
:ref:`hello_world` with west with this option set, use:
.. code-block:: sh
west build -b BOARD samples/hello_world -- -DEXTRA_CFLAGS=-save-temps=obj
west build -b BOARD samples/hello_world -- -DCONFIG_COMPILER_SAVE_TEMPS=y
This will create a preprocessor output file named :file:`foo.c.i` in the build
directory for each source file :file:`foo.c`.
