CheckFortranSourceRuns¶
New in version 3.14.
Check once if given Fortran source compiles and links into an executable and can subsequently be run.
- check_fortran_source_runs¶
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 Fortranprogram
.The result is stored in the internal cache variable specified by
<resultVar>
. Success of build and run is indicated by booleantrue
. Failure to build or run is indicated by booleanfalse
such as an empty string or an error message.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. TheSRC_EXT
option can be used to override this with.<extension>
instead.See also
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()
:
CMAKE_REQUIRED_FLAGS
String of additional flags to pass to the compiler. The string must be space-delimited--a ;-list will not work. The contents of
CMAKE_<LANG>_FLAGS
and its associated configuration-specific variable are automatically added to the compiler command before the contents ofCMAKE_REQUIRED_FLAGS
.
CMAKE_REQUIRED_DEFINITIONS
A ;-list of compiler definitions of the form
-DFOO
or-DFOO=bar
. A definition for the name specified by<resultVar>
will also be added automatically.
CMAKE_REQUIRED_INCLUDES
A ;-list of header search paths to pass to the compiler. These will be the only header search paths used--the contents of the
INCLUDE_DIRECTORIES
directory property will be ignored.
CMAKE_REQUIRED_LINK_OPTIONS
New in version 3.14.
A ;-list of options to add to the link command (see
try_compile()
for further details).
CMAKE_REQUIRED_LIBRARIES
A ;-list of libraries to add to the link command. These can be the name of system libraries or they can be Imported Targets (see
try_compile()
for further details).
CMAKE_REQUIRED_LINK_DIRECTORIES
New in version 3.31.
A ;-list of libraries search paths to pass to the linker (see
try_compile()
for further details).
CMAKE_REQUIRED_QUIET
New in version 3.1.
If this variable evaluates to a boolean true value, all status messages associated with the check will be suppressed.
