CheckFortranSourceRuns
----------------------
.. versionadded:: 3.14
This module provides a command to check whether a Fortran source can be built
and run.
Load this module in a CMake project with:
.. code-block:: cmake
include(CheckFortranSourceRuns)
Commands
^^^^^^^^
This module provides the following command:
.. command:: check_fortran_source_runs
Checks once whether the given Fortran source compiles and links into an
executable that can subsequently be run.
.. code-block:: cmake
check_fortran_source_runs(<code> <variable> [SRC_EXT <extension>])
The Fortran source supplied in ``<code>`` must contain a Fortran ``program``
unit. The result of the check is stored in the internal cache variable
specified by ``<variable>``. If the code builds and runs with exit code
``0``, success is indicated by a boolean true value. Failure to build or
run is indicated by a boolean false value, such as an empty string or an
error message.
The options are:
``SRC_EXT <extension>``
By default, the internal test source file used for the check will be
given a ``.F90`` file extension. This option can be used to change the
extension to ``.<extension>`` instead.
.. rubric:: Variables Affecting the Check
The following variables may be set before calling this command to modify
the way the check is run:
.. include:: /module/include/CMAKE_REQUIRED_FLAGS.rst
.. include:: /module/include/CMAKE_REQUIRED_DEFINITIONS.rst
.. include:: /module/include/CMAKE_REQUIRED_INCLUDES.rst
.. include:: /module/include/CMAKE_REQUIRED_LINK_OPTIONS.rst
.. include:: /module/include/CMAKE_REQUIRED_LIBRARIES.rst
.. include:: /module/include/CMAKE_REQUIRED_LINK_DIRECTORIES.rst
.. include:: /module/include/CMAKE_REQUIRED_QUIET.rst
Examples
^^^^^^^^
The following example shows how to use this module to check whether a Fortran
source code runs and store the result of the check in an internal cache
variable ``HAVE_COARRAY``:
.. code-block:: cmake
include(CheckFortranSourceRuns)
check_fortran_source_runs([[
program test
real :: x[*]
call co_sum(x)
end program
]] HAVE_COARRAY)

* The :module:`CheckSourceCompiles` module to check whether a source code
can be built.
#]=======================================================================]
include_guard(GLOBAL)
include(Internal/CheckSourceRuns)
macro(CHECK_Fortran_SOURCE_RUNS SOURCE VAR)
# Pass the SRC_EXT we used by default historically.
# A user-provided SRC_EXT argument in ARGN will override ours.
cmake_check_source_runs(Fortran "${SOURCE}" ${VAR} SRC_EXT "F90" ${ARGN})
