* Source: Adjust stack sizes and recursion limits to work togetherBrad King2023-03-131-7/+8
| | | | | | Adjust `CMake_DEFAULT_RECURSION_LIMIT` and/or the process stack size on each platform to pass the `RunCMake.MaxRecursionDepth` test's "default" cases.

* LCC: get rid of excess -Wunused-but-set-variable on release buildsmakise-homura2022-07-061-0/+9
| | | | | | | | | LCC, as of 1.26, has a buggy EDG frontend that emits -Wunused-but-set-variable warning even if there's something like "(void)var" when frontend optimizations are enabled (>=-O1). To get rid of this warning, we disable it in CMake's root CMakeLists.txt for LCC >= 1.26. Later, when this bug will be fixed in LCC, this version check will have its top version limit.
* Suppress MSVC 14.28 C5105 warning triggered by Windows SDKBrad King2020-11-171-0/+6
| | | | Issue: #21446
* Linux: Compile with _FILE_OFFSET_BITS=64 on 32-bit LinuxMarc Chevrier2020-09-231-0/+6
| | | | | | | | To avoid problems accessing filesystem, use 64-bit file offsets when compilation model is 32-bit. This explicit definition is needed now that KWSys does not provide LFS settings in its headers anymore. Fixes: #20568
* Check for support before adding bigtoc linker flagAlexander Grund2019-12-091-2/+10
| | | | Fixes: #20076
* Fixing warnings generated by clang 8.0 on WindowsZsolt Parragi2019-05-291-4/+7
| | | | | | | | | | | | * Deprecation removals previously specific to MSVC/Intel now also used by clang * String literals were assigned to non const pointers. These are stored in mutable arrays now * An implicit function pointer to pointer conversion is a Microsoft extension warning is suppressed by an explicit reinterpret_cast * The MSVC specific deprecation macro for jsoncpp was moved after the clang macro to avoid redefinition warnings. This is consistent with how jsoncpp fixed the issue in 36d8cfd7

* Remove now-unused code once used on IRIXBrad King2019-01-111-7/+0
| | | | | We dropped support for IRIX as a host platform long ago. Remove some leftover code.
* CMake: Enable /MP for MSVC toolchainRobert Dailey2018-02-151-0/+23
| | | | | | | | | | | | | A new cache option named `CMake_MSVC_PARALLEL` is now available that can be used to control the usage of [`/MP`][1] to the MSVC compiler. This enables parallelized builds on a per-translation unit basis. To enable `/MP`, specify value `ON` to the option. Using an integral non-zero value will control the specific number of threads used with the `/MP` option, as opposed to letting the toolchain decide for you. Fixes #17696 [1]: https://docs.microsoft.com/en-us/cpp/build/reference/mp-build-with-multiple-processes
* Windows: Increase stack size used by CMake binariesBrad King2018-01-301-0/+4
| | | | | | | | | Deep regex matching logic can exceed the default 1MB stack size. Until a better regex engine is used, simply push the problem over a farther horizon by increasing the stack size when built using a MSVC-compatible linker. Issue: #17659
* HP-UX: Drop support for building CMake on HP-UXBrad King2017-08-071-12/+0
| | | | | | | | CMake will soon require both C++11 and libuv to build. Neither of these works on HP-UX, so unfortunately we need to drop support for the platform until someone can get them working. Issue: #17137
* SunPro: update flags used for CMake itselfDaniel Pfeifer2017-05-261-1/+2
| | | | | Special flags should no longer be required when CMake is built with a recent version of CMake.
* Update SunPro flags used for CMake itself to support C++11Brad King2017-05-081-1/+8

* Drop Visual Studio 7 .NET 2003 generatorBrad King2017-04-191-4/+0
| | | | This generator has been deprecated since CMake 3.6. Remove it.
* CompileFlags: Tell PGI compiler not to issue warning diagnosticsBrad King2016-09-281-0/+7
| | | | | | | When hosting CMake's own build with the PGI compiler there are several warnings that cannot easily be fixed or suppressed. We have enough code quality tools and warnings from other compilers that it is unlikely a PGI-only warning is useful.
* Simplify CMake per-source license noticesBrad King2016-09-271-11/+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.
* Modules: Fix typos in name of `CMAKE_COMPILER_IS_GNUCC` variableBrad King2016-09-141-1/+1
| | | | | | It is not called `CMAKE_COMPILER_IS_GNUC` (without last `C`). Closes: #16297

* | SolarisStudio: Use alternative standard library to build CMake.Stephen Kelly2015-01-111-0/+8
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SolarisStudio ships a very old RogueWave standard library implementation (libCstd) and uses it by default for backward compatibility. The macros defined when building the system libCstd need to be the same as the macros defined when using it for binary compatibility reasons etc. The SolarisStudio compiler driver adds macros such as _RWSTD_NO_MEMBER_TEMPLATES and _RWSTD_NO_CLASS_PARTIAL_SPEC etc. These macros disable certain APIs in the standard library headers. Although the compiler supports the features 'member templates' and 'partial template specialization', the standard library does not provide APIs which rely on those features. This means that std::vector::insert in libCStd does not accept a pair of iterators from a different type of container, because that requires member templates, and reverse_iterator<const T> can not be constructed from a reverse_iterator<T> because that requires partial specialization (or at least the _RWSTD_NO_CLASS_PARTIAL_SPEC define) and member templates. This causes many problems while building CMake using SolarisStudio, which have not been well understood until now. The problems are usually attributed to compiler limitations, while actually the problem is in the standard library, as in commit v3.0.0-rc1~99^2~1 (Help: Document non-use of std::set::insert., 2014-01-24) and commit 107dcac3 (Fix compilation with the Oracle / Sun compiler (#15318), 2014-12-12). SolarisStudio 12.3 and earlier also ships a version of stlport which may be used instead of libCstd by specifying -library=stlport4 https://docs.oracle.com/cd/E18659_01/html/821-1383/bkakg.html SolarisStudio 12.4 ships a version of libstdc++ from GCC 4.8.2 which may be used by specifying -std=c++03 or -std=c++11 etc http://docs.oracle.com/cd/E37069_01/html/E37075/bkamw.html#OSSCPgnaof Use these more-capable standard library implementations when building cmake. This will allow more use of 'normal' C++ (such as std::vector::insert), and cause fewer surprises resulting from dashboards using SolarisStudio. Because cmake is not a library linked against by 3rd parties and does not have external dependencies, issues related to mixing code using libCStd and libstdc++ do not apply.

| * Workaround for short jump tables on PA-RISC.Chuck Atkins2014-11-101-6/+10
| | | | | | | | | | | | | | The PA-RISC architecture requires special options for GCC to prevent linker errors when libraries reach a certain size and / or complexity. See http://mraw.org/blog/2007/10/10/Linking_on_hppa and gcc documentation on -mlong-calls.
* | Avoid if() quoted auto-dereferenceBen Boeckel2014-10-201-1/+1
|/ | | | | | | When testing CMAKE_<LANG>_COMPILER_ID values, do not explicitly dereference or quote the variable. We want if() to auto-dereference the variable and not its value. Also replace MATCHES with STREQUAL where equivalent.

* Remove CMake-language block-end command argumentsKitware Robot2012-08-131-10/+10
| | | | | | | | | | | | | | | | | Ancient versions of CMake required else(), endif(), and similar block termination commands to have arguments matching the command starting the block. This is no longer the preferred style. Run the following shell code: for c in else endif endforeach endfunction endmacro endwhile; do echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | egrep -z -v 'Tests/CMakeTests/While-Endwhile-' | xargs -0 sed -i -f convert.sed && rm convert.sed
* Convert CMake-language commands to lower caseKitware Robot2012-08-131-36/+36
| | | | | | | | | | | | | | | | | Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case. Run the following shell code: cmake --help-command-list | grep -v "cmake version" | while read c; do echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | xargs -0 sed -i -f convert.sed && rm convert.sed

* Re-disable MSVC CRT deprecation warningsBrad King2009-10-281-1/+6
| | | | | | The commit "Disable Intel CRT deprecation warnings" broke the logic that disabled MS's CRT deprecation warnings. This fixes the logic to disable the warnings for both MSVC and Intel.
* Disable Intel CRT deprecation warningsBrad King2009-10-271-2/+2
| | | | | | The Intel Compiler for Windows uses the MS runtime library which deprecates many C functions. We define _CRT_SECURE_NO_DEPRECATE and _CRT_NONSTDC_NO_DEPRECATE to disable the deprecation warnings.
