* Modules: Drop redundant check logging to CMakeOutput.log and CMakeError.logBrad King2023-01-181-6/+0
| | | | | | | | | | `try_compile` and `try_run` now automatically log checks using them to `CMakeConfigureLog.yaml`. Add `LOG_DESCRIPTION` arguments to some `try_compile` calls to replace the description previously written to the old logs. Issue: #23200
* Modules: Use new SOURCES_FROM_* try_compile (1/2)Matthew Woehlke2022-09-271-3/+3
| | | | | | | | | | | Modify some modules that ship with CMake to use the new SOURCES_FROM_* arguments to try_compile / try_run as added by commits cb14ae2b87 (try_compile: Add SOURCE_FROM_{ARG,VAR}, 2022-09-21) and 611d801790 (try_compile: Add SOURCE_FROM_FILE, 2022-09-22). This covers users which previously either used an existing file (but sometimes needed to rename it), or which wrote out their source in entirety. It does NOT cover users that actually need configure_file functionality, as those will be more involved to update and will thus be tackled in part 2.
* Modules: Use new keyword-dispatched try_compile signatureMatthew Woehlke2022-09-141-2/+2
| | | | | | | | | | | Modify most of the modules that ship with CMake to use the new try_compile / try_run signatures added by commit aa9220d3a0 (try_compile: Add keyword-dispatched signature, 2022-09-02). This improves debugging by each invocation using its own directory so that the results of multiple invocations can be retained. This does not cover any invocations which provide an entire project, as that flavor of try_compile has not yet been updated.
* enable_language: Fix test for working compiler with CMP0126 NEW behaviorBrad King2021-07-151-0/+3
| | | | | | | | | | | | | | Update the logic that converts a `try_compile` result from a cache entry to a normal variable to tolerate an existing normal variable under CMP0126 NEW behavior. Otherwise the `try_compile` result is ignored because CMake uses the false value of the normal variable, and CMake incorrectly reports that the compiler does not work. This went unnoticed for some languages (e.g. C and CXX) because the check for a working compiler is skipped if ABI detection works. It does affect other languages (e.g. CSharp). Fixes: #22423
* Swift: Exclude SDK include pathsYauheni Khnykin2020-02-101-0/+5
| | | | | | | | Populate `CMAKE_Swift_IMPLICIT_INCLUDE_DIRECTORIES` with the macOS SDK's include directory so that we filter such implicit directories out of Swift targets. Fixes: #19845
* Refactor: Use added message types in various modulesAlex Turbov2019-11-021-3/+3

* Modules: add build rules for Swift Ninja supportSaleem Abdulrasool2019-05-161-2/+5
| | | | Add rules to support building Swift sources using Ninja.
* Maint: misc. typosluz.paz2018-02-161-1/+1
| | | | Found via `codespell`
* Improve formatting of compiler failure error messageBrad King2017-09-191-2/+3
| | | | | | When we report that a compiler was unable to build a simple test program, indent the output of the attempt so that our message formatting will show it as a pre-formatted block.
* Simplify CMake per-source license noticesBrad King2016-09-271-12/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.
* Swift: Add proper Swift compiler testGregor Jasny2015-09-061-1/+51
| | | | | This catches for example the unavailability of Swift with Xcode Beta6 and macosx10.10 SDK.
* Add rudimentary support for the Apple Swift language with XcodeBrad King2015-07-061-0/+15
Allow the `Swift` language to be enabled with the Xcode generator for Xcode >= 6.1. Reject it on other generators and with older Xcode versions. Since Apple is the only vendor implementing the language right now, the compiler id can be just `Apple`.
