* try_compile: Record propagated CMake variables in configure logBrad King2023-02-011-0/+21
| | | | | | | These provide more detailed information about how the test project was configured. Issue: #23200

* TryCompileCode(): Prevent warning on return valueCraig Scott2022-12-291-1/+2
| | | | | | | | | | Some newer compilers warn in situations where the returned local variable could be movable, but a C++11 defect meant older compilers may still return a copy when a type conversion is involved. Adding the suggested std::move prevents that warning on that compiler, but creates a new warning on others. Constructing the actual return type explicitly with the suggested std::move on the constructor argument keeps both sets of compilers happy.
* ConfigureLog: Log try_compile and try_run checksMatthew Woehlke2022-12-161-0/+23
| | | | | | Add configure log events for `try_compile` and `try_run` results. Issue: #23200
* cmCoreTryCompile: Return more semantic information from compile stepBrad King2022-12-141-26/+29
| | | | | | Update the `TryCompileCode` signature to allow callers to distinguish between administrative failures and a compilation failure. Return results in a structure to which more information can be added later.
* try_compile: Restore COPY_FILE with CMAKE_TRY_COMPILE_CONFIGURATIONBrad King2022-11-221-4/+11
| | | | | | | | | Since commit 0c141b0393 (try_compile: Record output location instead of reverse computing it, 2022-08-31, v3.25.0-rc1~154^2) we always look for the "Debug" configuration's output binary from the test project. Restore looking for the `CMAKE_TRY_COMPILE_CONFIGURATION`. Fixes: #24180

| * try_compile: Honor CMP0128 setting in test projectBrad King2022-10-181-0/+6
| | | | | | | | | | | | | | | | | | Some projects pass a raw `-std=` flag to the compiler in the `try_compile` project. If they do not set CMP0128 to NEW, we should not append a `-std=` flag where we did not before the policy was added. Fixes: #24063
* | try_compile: Report build dir with --debug-trycompileMatthew Woehlke2022-10-061-0/+7
| | | | | | | | | | | | | | | | When `--debug-trycompile` is enabled, issue a log (with trace) for every `try_compile` noting what directory is being used for the compilation. This will make it easier to find the corresponding artifacts. Closes: #24022
* | try_compile: Rename SOURCE_FROM_ARG -> SOURCE_FROM_CONTENTMatthew Woehlke2022-09-301-9/+10
| | | | | | | | | | | | | | | | | | Change the SOURCE_FROM_ARG keyword to try_compile to SOURCE_FROM_CONTENT (which we can do because it was recently added and hasn't been in a release yet). The new name should be clearer as to what it does, and also more consistent with the CONTENT arguments to some other commands. Also, fix a typo in an error message.
* | try_compile: Add NO_CACHE option (also try_run)Matthew Woehlke2022-09-281-3/+9
| | | | | | | | | | | | | | Add NO_CACHE option to try_compile and try_run, which places the results in regular, rather than cache, variables. Issue: #22799

| * | try_compile: Add SOURCE_FROM_FILEMatthew Woehlke2022-09-221-0/+32
| | | | | | | | | | | | | | | | | | | | | Add ability to copy try_compile (and try_run) source files from arbitrary locations into the operation directory. This is included for the sake of completion and consolidation, although use cases which actually require this may be rare.
| * | try_compile: Add SOURCE_FROM_{ARG,VAR}Matthew Woehlke2022-09-221-8/+84
| | | | | | | | | | | | | | | | | | | | | | | | Add ability to "feed" try_compile (and try_run) sources more directly, either from literal content, or from a CMake variable which contains literal content. This saves the user from needing a separate step to write the content to a file, and allows for the sources to only exist in the scratch directory.

| |/ / | | | | | | | | | | | | | | | Remove PROJECT support from try_run; it was never tested, has never been documented, and it's unclear how it should even work (since CMake wouldn't know what executable to run).

* | try_compile: Add PROJECT keyword-dispatched signatureMatthew Woehlke2022-09-141-30/+70
| | | | | | | | | | | | | | Introduce a new signature for the project flavor of try_compile (and try_run) which removes the `bindir` argument and adds a required PROJECT tag. This is similar to the SOURCES flavor added by commit aa9220d3 (try_compile: Add keyword-dispatched signature, 2022-09-02).

| * | MSVC: Add abstraction for debug information formatGlen Chung2022-09-141-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace our hard-coded default for `/Zi` with a first-class abstraction to select the debug information format an enumeration of logical names. We've long hesitated to do this because the idea of "debug information format" touches on related concepts on several platforms. Avoid that scope creep by simply defining an abstraction that applies only when targeting the MSVC ABI on Windows. Removing the old default flag requires a policy because existing projects may rely on string processing to edit them and choose a runtime library under the old behavior. Add policy CMP0141 to provide compatibility. Fixes: #10189

* | try_compile: Add keyword-dispatched signatureMatthew Woehlke2022-09-051-20/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new signature for try_compile (and try_run) which removes the `bindir` argument and requires the SOURCES tag. This will eventually allow us to add other ways of providing sources, but also allows us to change the behavior without breaking compatibility. The old signature uses a special, but non-unique temporary location inside the specified `bindir`, which conventionally is just the project's build directory. The new signature unconditionally uses the a unique temporary directory which is unconditionally within the project's build directory (which is no longer separately specified). This ensures that successive runs do not overwrite previous runs, will simplify debugging, and should also, eventually, allow us to execute multiple trials in parallel.
* | try_compile: Don't accept try_run argumentsMatthew Woehlke2022-08-171-26/+6
| | | | | | | | | | | | | | | | | | | | | | Modify cmCoreTryCompile to only recognize try_run arguments when actually parsing try_run. (The old behavior was to recognize try_run arguments for try_compile also and then complain.) This has a small chance that a try_run keyword will be consumed as part of a multi-valued keyword argument. However, this behavior is more consistent with other commands, as we don't normally treat keywords as universally reserved. Also, the code is noticeably simplified.
* | try_compile: Fix quotes in reporting of unknown argumentsMatthew Woehlke2022-08-171-1/+1
| | | | | | | | | | | | | | | | In commit 6b427d8da9 (cmCoreTryCompile: Port to cmArgumentParser, 2022-08-01) we inadvertently dropped a matching quote during refactoring of reporting unknown arguments given to try_compile/try_run. Add the missing quote to match the old behavior and not have an imbalanced quote in the warning.

* CheckSourceCompiles: Avoid linker warning with -fembed-bitcodeCraig Scott2022-04-091-0/+6
| | | | | | | | | | | | | | | When the Apple linker sees -headerpad_max_install_names and bitcode is enabled with a flag like -fembed-bitcode, it issues a warning and ignores the -headerpad_max_install_names flag. This causes unrelated compiler and linker flag checks to fail for valid flags. In f745e0497e (CheckCompilerFlags: Catch linker warning about ignored flags, 2022-01-03), we started detecting linker warnings, which caused a regression for projects that were setting -fembed-bitcode in their CMAKE_CXX_FLAGS or similar. Prevent that regression by removing the -headerpad_max_install_names linker flag when we know it will warn and be ignored anyway. Fixes: #23390 Issue: #23408
