CMAKE_EXPORT_BUILD_DATABASE
|
||
|
|
---------------------------
|
||
|
|
|
||
|
|
.. versionadded:: 3.31
|
||
|
|
|
||
|
|
.. note ::
|
||
|
|
|
||
|
|
This variable is meaningful only when experimental support for build
|
||
|
|
databases has been enabled by the
|
||
|
|
``CMAKE_EXPERIMENTAL_EXPORT_BUILD_DATABASE`` gate.
|
||
|
|
|
||
|
|
Enable/Disable output of module compile commands during the build.
|
||
|
|
|
||
|
|
If enabled, generates a ``build_database.json`` file containing the
|
||
|
|
information necessary to compile a target's C++ module sources with any
|
||
|
|
tooling. The format of the JSON file looks like:
|
||
|
|
|
||
|
|
.. code-block:: javascript
|
||
|
|
|
||
|
|
{
|

This is initialized by the :envvar:`CMAKE_EXPORT_BUILD_DATABASE` environment
|
||
|
|
variable, and initializes the :prop_tgt:`EXPORT_BUILD_DATABASE` target
|
||
|
|
property for all targets.

.. note::
|

|
This option is implemented only by the :ref:`Ninja Generators`. It is
|
||
|
|
ignored on other generators.
|
||
|
|
|
||
|
|
When supported and enabled, numerous targets are created in order to make it
|
||
|
|
possible to build a file containing just the commands that are needed for the
|
||
|
|
tool in question.

|
|
|
||
|
|
``cmake_build_database-<CONFIG>``
|
||
|
|
Writes ``build_database_<CONFIG>.json``. Writes a build database for the
|
||
|
|
entire build for the given configuration and all languages. Not available if
|
||
|
|
the configuration name is the empty string.
|
||
|
|
|
||
|
|
``cmake_build_database-<LANG>-<CONFIG>``
|
||
|
|
Writes ``build_database_<LANG>_<CONFIG>.json``. Writes build database for
|
||
|
|
the entire build for the given configuration and language. Not available if
|
||
|
|
the configuration name is the empty string.
|
||
|
|
|
||
|
|
``cmake_build_database-<LANG>``
|
||
|
|
Writes ``build_database_<LANG>.json``. Writes build database for the entire
|
||
|
|
build for the given language and all configurations. In a multi-config
|
||
|
|
generator, other build configuration database may be assumed to exist.
|
||
|
|
|
||
|
|
``cmake_build_database``
|
||
|
|
Writes to ``build_database.json``. Writes build database for all languages
|
||
|
|
and configurations. In a multi-config generator, other build configuration
|
||
|
|
database may be assumed to exist.
