* | CMakeDetermineCompilerId: check with and without user-specified flagsMichael Maltese2017-02-061-19/+28
|/ | | | | | | | | | | Clang may raise an error when passed a `-march=` option that doesn't correspond to the current target triple. CMake cannot pass the target triple when determining the compiler id because it doesn't know how yet, but it does pass along user-specified flags. This breaks when those user-specified flags include `-march=`. Fix this use case by also trying to find the compiler id without the user-specified flags. Fixes: #16587

* VS: Provide an option to use x64 host toolsBrad King2016-10-141-0/+5
| | | | | | | | | | Visual Studio provides toolchains that are themselves built for 32-bit or 64-bit host architectures. By default it uses the 32-bit tools, but it can be told to prefer the 64-bit tools on 64-bit hosts. Extend the `CMAKE_GENERATOR_TOOLSET` specification to provide a way to request use of the 64-bit host tools. Closes: #15622
* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.
* Xcode: Port rudimentary Swift support to Xcode 8Brad King2016-09-231-0/+5
| | | | | | The `.pbxproj` file must now specify a `SWIFT_VERSION` value. Set it to the legacy value of "2.3" for now. Later this can be made configurable (e.g. to "3.0").

* CMakeDetermineCompilerId: Fix compiler id with square brackets in the pathBrad King2016-06-021-2/+3
| | | | | | | | | | We use file(GLOB) to load the list of files produced by compiling the compiler identification source. Encode square brackets in the path to the directory so that they are not treated as special characters in the globbing expression. Otherwise we fail to find any files when the path contains square brackets and the compiler id is unknown. Reported-by: Esch Nigma <eschnigma@openmailbox.org>
* Ninja: Fix clang-cl /showIncludes prefix detectionBrad King2016-05-031-2/+2
| | | | | | | | | We run MSVC-like compilers with the `/showIncludes` option and match the output to extract the corresponding message. Fix the matching to support compilers like `clang-cl` that print the message on the first line such that it is not preceded by a newline. LLVM-Issue: https://llvm.org/bugs/show_bug.cgi?id=27226

| | | | | | | | | | | | | | VS expects the platform to be just `Itanium`, so drop the incorrect special case mapping it to `ia64`. This platform name has been wrong since the logic was added by commit v2.8.10~148^2~8 (VS: Detect the compiler id and tool location, 2012-08-16).

| | | | | | | | | | | | | | | | In commit v3.4.0-rc1~18^2 (Disable shared library support when compiler links statically, 2015-09-30) we tried to detect when the compiler is not capable of linking shared libraries (possibly due to flags in use). However, the approach is not robust against flags like `-nostdlib`. Revert it for now pending another solution to the original problem.

| * VS: Add support for selecting the Windows 10 SDK (#15670)Gilles Khouzam2015-10-021-0/+3
| | | | | | | | | | | | | | | | | | Teach the VS 2015 generator to produce a WindowsTargetPlatformVersion value. Use the CMAKE_SYSTEM_VERSION to specify the version and if not set choose a default based on available SDKs. Activate this behavior when targeting Windows 10.

* | Disable shared library support when compiler links staticallyBrad King2015-09-301-0/+8
|/ | | | | | | | | When a user or a compiler wrapper adds '-static' to the compiler flags then it will always link static binaries. Detect this from the compiler id binary and disable TARGET_SUPPORTS_SHARED_LIBS. This will prevent projects from accidentally adding shared libraries when the toolchain does not support them. It also helps CMake avoid linking with flags that require shared libraries to be supported.
* Ninja: Detect MSVC /showIncludes prefix with compiler flags (#15596)Brad King2015-09-181-0/+31
| | | | | | | | Move detection over to the compiler id logic where we have already constructed the list of compiler flags from ARG1 and CMAKE_<LANG>_FLAGS. Pass the flags when we execute "cl" with "/showIncludes". Also pass "/c" because we only need to compile, not link. Check the compiler process exit code before trusting its output.
* CMakeDetermineCompilerId: Drop unused code pathBrad King2015-09-181-23/+11
| | | | | The execute_process command always exists so we never need to fall back on exec_program.
* Project: Determine default language dialect for the compiler.Stephen Kelly2015-09-181-0/+5
| | | | | | Use the __cplusplus and __STDC_VERSION__ macros to automatically determine the default dialect for the compiler while determining its id and version.
* CMakeDetermineCompilerId: Use per-language regex to match Xcode compiler toolBrad King2015-06-301-9/+6
| | | | | | Move the Ld invocation match expression from CMakeDetermineCompilerId into CMakeDetermine{C,CXX,Fortran}Compiler so that it can be specified on a per-language basis.
* CMakeDetermineCompilerId: Simplify src reference in IDE projectsBrad King2015-06-251-2/+2
| | | | | | | | When constructing the "id_src" value for substitution into VS or Xcode compiler id projects, the input "src" variable already contains the file name with no path so we do not need get_filename_component. We know this because CMAKE_DETERMINE_COMPILER_ID_WRITE already references "${src}" with this assumption.
* CMakeDetermineCompilerId: Try matching compiler output to detect idBrad King2015-06-181-0/+19
| | | | | | Some compilers can only be distinguished by their compilation output rather than preprocessor symbols or special flags. Add infrastructure to determine the compiler id by matching output.
* CMakeDetermineCompilerId: Refactor id build/check loop logicBrad King2015-06-181-5/+6
| | | | | | | | Callers of CMAKE_DETERMINE_COMPILER_ID initialize the CMAKE_${lang}_COMPILER_ID to unset so we can check it at the end of each loop iteration instead of the beginning. This approach allows us to break out of the loop as soon as we succeed. It will also allow checks to be added in more places within the loop later.
* CMakeDetermineCompilerId: Optionally try some flags before no flagsBrad King2015-06-181-1/+3
| | | | | | | | Teach CMAKE_DETERMINE_COMPILER_ID to optionally try detecting the compiler id using some given flags before trying to detect it with no special flags. This will be useful for Fortran detection to distinguish some compilers that use the preprocessors of others but have no macro of their own by getting verbose output.
* MSVC: Distinguish among ARM architectures more precisely (#14552)Gunnar Roth2015-02-241-2/+0
| | | | | Detect the exact ARM architecture instead of just "ARM". Treat "ARM" as an architecture family that includes THUMB (ARMV4I and ARMV5I).
* Fortran: Add infrastructure to detect compiler version (#15372)Brad King2015-02-191-1/+40
| | | | | | | | Fortran does not offer syntax to compose a string literal at preprocessing time from numeric compuations. Instead encode each digit of each component as a separate INFO string and compose them in CMake code after extraction. Support MAJOR, MINOR, PATCH, and TWEAK components with up to 8 digits each.

| | | | | | | | | | | | | | In commit v3.1.0-rc1~113^2 (Use a more reliable regex for extracting binary INFO strings, 2014-09-03) the matching of INFO: strings was made more strict and no longer matches just "INFO:qnxnto". Use "INFO:qnxnto[]" instead to conform to the new pattern.

| |/ | | | | | | | | | | | | | | The approach in commit v3.1.0-rc1~1^2 (Xcode: Fix compiler id detection when code signing is required, 2014-10-22) still requires a code signing key when targeting a real device. Instead set CODE_SIGNING_REQUIRED to "NO" to tell Xcode not to sign at all. Drop the corresponding setting of the code signing identity.

| * Xcode: Fix compiler path detection for iOS tools on Xcode <= 5.0 (#15237)Brad King2014-11-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | Since commit v3.1.0-rc1~1^2~1 (Xcode: Fix compiler id detection for iOS tools, 2014-10-22) our compiler id detection project sets the product type to 'com.apple.product-type.bundle.unit-test'. This causes the Ld command line on which we match the path to the compiler to have a 'CompilerIdC.xctest/' component. The commit updated our regex to match this, but placed it before the extra './' component that Xcode 5.0 and below produce. Xcode <= 5.0 prints '/./CompilerIdC.xctest/', so switch the order of the two components in the regex to match it.

| | | | | | | | | | | | | | | | | | | | The iOS product type 'com.apple.package-type.bundle.unit-test' requires code signing on Xcode 6. Other iOS target types do too. Until CMake learns to add the CODE_SIGN_IDENTITY build attribute itself, toolchain files can set CMAKE_XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY to tell the Xcode generator to add the attribute. Teach CMakeDetermineCompilerId to recognize this variable and add the CODE_SIGN_IDENTITY build attribute to the compiler id project.
| * Xcode: Fix compiler id detection for iOS tools (#15214)Brad King2014-10-221-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 0cce556b (Xcode: Use sysroot and deployment target to identify compiler, 2014-04-29) our compiler id detection project uses the target platform SDK in case Xcode selects a different compiler based on it. Now the compiler id project actually compiles with the target compiler and SDK when cross-compiling. The iOS tools do not support the 'com.apple.product-type.tool' product type we use in our compiler id detection project. When targeting iPhone, use product type 'com.apple.product-type.bundle.unit-test' instead.
* | Avoid if() quoted auto-dereferenceBen Boeckel2014-10-201-1/+1
