CheckFortranSourceRuns
----------------------
.. versionadded:: 3.14
Check once if given Fortran source compiles and links into an executable and can
subsequently be run.
.. command:: check_fortran_source_runs
.. code-block:: cmake
check_fortran_source_runs(<code> <resultVar>
[SRC_EXT <extension>])
Check once that the source supplied in ``<code>`` can be built, linked as an
executable, and then run. The ``<code>`` must contain a Fortran ``program``.
The result is stored in the internal cache variable specified by
``<resultVar>``. If the code builds and runs with exit code ``0``, success is
indicated by boolean ``true``. Failure to build or run is indicated by boolean
``false``, such as an empty string or an error message.
.. code-block:: cmake
check_fortran_source_runs("program test
real :: x[*]
call co_sum(x)
end program"
HAVE_COARRAY)
By default, the test source file will be given a ``.F90`` file extension. The
``SRC_EXT`` option can be used to override this with ``.<extension>`` instead.
See also :command:`check_source_runs` for a more general command syntax.
The compile and link commands can be influenced by setting any of the
following variables prior to calling ``check_fortran_source_runs()``:
.. include:: /module/CMAKE_REQUIRED_FLAGS.txt
.. include:: /module/CMAKE_REQUIRED_DEFINITIONS.txt
.. include:: /module/CMAKE_REQUIRED_INCLUDES.txt
.. include:: /module/CMAKE_REQUIRED_LINK_OPTIONS.txt
.. include:: /module/CMAKE_REQUIRED_LIBRARIES.txt
