CUDA_STANDARD
|
|
-------------
|
|
|
|
.. versionadded:: 3.8
|
|
|
|
The CUDA/C++ standard whose features are requested to build this target.
|
|
|
|
This property specifies the CUDA/C++ standard whose features are requested
|
|
to build this target. For some compilers, this results in adding a
|
|
flag such as ``-std=gnu++11`` to the compile line.
|
|
|
|
Supported values are:
|
|
|
|
``98``
|
|
CUDA C++98. Note that this maps to the same as ``03`` internally.
|
|
|
|
``03``
|
|
CUDA C++03
|
|
|
|
``11``
|
|
CUDA C++11
|
|
|
|
``14``
|
|
CUDA C++14. While CMake 3.8 and later *recognize* ``14`` as a valid value,
|
|
CMake 3.9 was the first version to include support for any compiler.
|
|
|
|
``17``
|
|
CUDA C++17. While CMake 3.8 and later *recognize* ``17`` as a valid value,
|
|
CMake 3.18 was the first version to include support for any compiler.
|
|
|
|
``20``
|
|
.. versionadded:: 3.12
|
|
|
|
CUDA C++20. While CMake 3.12 and later *recognize* ``20`` as a valid value,
|
|
CMake 3.18 was the first version to include support for any compiler.
|
|
|
|
``23``
|
|
.. versionadded:: 3.20
|
|
|
|
CUDA C++23
|
|
|
|
``26``
|
|
.. versionadded:: 3.25
|
|
|
|
CUDA C++26. CMake 3.25 and later *recognize* ``26`` as a valid value,
|
|
no version has support for any compiler.
|
|
|
|
If the value requested does not result in a compile flag being added for
|
|
the compiler in use, a previous standard flag will be added instead. This
|
|
means that using:
|
|
|
|
.. code-block:: cmake
|
|
|
|
set_property(TARGET tgt PROPERTY CUDA_STANDARD 11)
|
|
|
|
with a compiler which does not support ``-std=gnu++11`` or an equivalent
|
|
flag will not result in an error or warning, but will instead add the
|
|
``-std=gnu++03`` flag if supported. This "decay" behavior may be controlled
|
|
with the :prop_tgt:`CUDA_STANDARD_REQUIRED` target property.
|
|
Additionally, the :prop_tgt:`CUDA_EXTENSIONS` target property may be used to
|
|
control whether compiler-specific extensions are enabled on a per-target basis.
|
|
|
|
See the :manual:`cmake-compile-features(7)` manual for information on
|
|
compile features and a list of supported compilers.
|
|
|
|
This property is initialized by the value of
|
|
the :variable:`CMAKE_CUDA_STANDARD` variable if it is set when a target
|
|
is created.
