There was a mismatch in the executable suffix between the compiler
detection and try_compile. This resulted in the generated executable
having a different suffix than what try_compile was looking for.
The IAR module is changed to use the same suffix as try_compile.
Fixes: #22567
The MPI libraries use a compiler wrapper to automatically inject
required flags and libraries into the compiler argument list. However,
the wrapper does not support cross-compiling: the wrapper will try to
invoke the native compiler which cannot handle the cross architecture
MPI libraries and fail.
This MR adds some fallback code for this case, which tries to bypass the
faulty wrapper and determine the necessary flags and libraries directly
from the MPI pkg-config files. The patch tries to be as unintrusive as
possible and should not break any existing use-cases.
Fixes: #22650
The `MINGW` variable indicates that the compiler targets MinGW, a GNU
ABI on Windows. Since commit aff3147917 (Modernize GNU compiler info on
Windows, 2009-12-02, v2.8.2~636), we load the `Platform/Windows-GNU`
module for compilers targetin MinGW, so set the variable there instead.
This is equivalent to `Platform/Windows-MSVC` setting the `MSVC`
variable. Also remove `if(MINGW)` checks from the module, which have
not been necessary since the enclosed logic was moved to that module.
The undocumented `CMAKE_COMPILER_IS_MINGW` internal variable is now
unused, so remove it too.
Fixes: #22647
It only makes sense to use the CMake package from the same ROCm
installation that the compiler uses. Ask the HIP compiler to report the
location of the ROCm installation. Verify up front that it contains the
expected CMake package file.
Since commit bd844387df (ROCMClang: Add the ROCm toolkit derived clang
compiler to CMake, 2020-08-28, v3.21.0-rc1~66^2~6) and commit ff0d2858e1
(HIP: Extract clang compiler details from hipcc, 2020-10-21,
v3.21.0-rc1~66^2~5), the separate `ROCMClang` compiler id for `hipcc`
has caused a few problems:
* The compiler id changed from behavior of CMake 3.20 and below,
breaking projects that already built with `hipcc` treated as `Clang`.
* The implementation of `target_compile_features` was incomplete for
the `ROCMClang` identity.
* Only `hipcc` was identified as `ROCMClang`, so after it is unwrapped
to the underlying `clang++`, future runs of new CMake versions on
an existing build tree would not repeat this.
* Clang should be usable as a HIP compiler without the `hipcc` wrapper.
Remove the `ROMClang` compiler identity, and revise HIP language support
to work directly with a Clang compiler.
Reject direct `hipcc` usage as a HIP compiler. For now it cannot be
supported because it interferes with flags CMake needs to pass to Clang.
Fixes: #22536, #22460, #22593
Fail early if it is not found.
Use the detected location as a hint to find `rocm_agent_enumerator`.
Also remove the leading `_` prefix in case we want to document this
publicly later.
These are set by modules loaded for `CMAKE_SYSTEM_NAME`. We do not
need to set them again if the compiler defines `__CYGWIN__`.
Also remove the now-unused undocumented `CMAKE_COMPILER_IS_CYGWIN`
internal variable.
Since commit a7f41a7ee4 (Android: Fix find_* search order within NDK for
unified toolchains, 2020-10-13, v3.20.0-rc1~610^2), we turn off
`CMAKE_FIND_USE_SYSTEM_ENVIRONMENT_PATH`. This breaks `find_program`
searching `PATH` for host executables. Fortunately, the setting turns
out not to be necessary, perhaps since commit cbc51a8be3 (Android:
restructure android search paths, 2020-11-06, v3.20.0-rc1~509^2).
Without it, none of NDK tests fail, so remove it to restore pre-3.20
behavior.
Fixes: #22634
Since commit 5b9bfe738c (IAR: Moved search logic to BinUtils.,
2021-07-19, v3.21.1~14^2), we use the `IN_LIST` operator in the
`CMakeFindBinUtils` module. Set policy `CMP0057` to ensure it is
available regardless of the project's policy settings.
Fixes: #22640
FindFLTK could store multiple entries in `FLTK_INCLUDE_DIR`,
and when re-executed would stored into `FLTK_DIR` which had
uses which presumed single entries.
Fixes#13198
No matter the OS when installing for conda the library components
need to be placed into the `lib` directory.
To better meet these requirements GNUInstallDirs now checks to see
if it is being asked to install into a conda install location,
and if so use the 'lib' directory instead of the system directory
name.
This was forgotten in commit 0c7f918fb1 (VS: Update Visual Studio 17
2022 generator for Preview 2, 2021-07-14, v3.21.1~29^2) when the toolset
was first renumbered to `v143`.
Fixes: #22585
Update the list of known versions.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_77_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.77.0 source tree. The dependencies
differ from those of 1.76: the `contract`, `thread`, and `wave`
components no longer depend on `date_time`. The `math` component no
longer depends on `atomic`.
