CheckOBJCSourceRuns¶
New in version 3.16.
Check once if given Objective-C source compiles and links into an executable and can subsequently be run.
- check_objc_source_runs¶
check_objc_source_runs(<code> <resultVar>)
Check once that the source supplied in
<code>can be built, linked as an executable, and then run. The<code>must contain at least amain()function.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 booleanfalsesuch as an empty string or an error message.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_objc_source_runs()
CMAKE_REQUIRED_FLAGSString of additional flags to pass to the compiler. The string must be space-delimited--a ;-list will not work. The contents of
CMAKE_<LANG>_FLAGSand its associated configuration-specific variable are automatically added to the compiler command before the contents ofCMAKE_REQUIRED_FLAGS.
CMAKE_REQUIRED_DEFINITIONSA ;-list of compiler definitions of the form
-DFOOor-DFOO=bar. A definition for the name specified by<resultVar>will also be added automatically.
CMAKE_REQUIRED_INCLUDESA ;-list of header search paths to pass to the compiler. These will be the only header search paths used--the contents of the
INCLUDE_DIRECTORIESdirectory property will be ignored.
CMAKE_REQUIRED_LINK_OPTIONSNew in version 3.14.
A ;-list of options to add to the link command (see
try_compile()for further details).
CMAKE_REQUIRED_LIBRARIESA ;-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_DIRECTORIESNew in version 3.31.
A ;-list of libraries search paths to pass to the linker (see
try_compile()for further details).
CMAKE_REQUIRED_QUIETNew in version 3.1.
If this variable evaluates to a boolean true value, all status messages associated with the check will be suppressed.
