clang-tidy is missing since llvm-mingw 16

the last release contains clang-tidy is https://github.com/mstorsjo/llvm-mingw/releases/tag/20230320
Yes; last year I switched the release process over to be built on github actions - this was discussed in #336. As part of tradeoffs done there, I decided to omit clang-tools-extra from the unix builds, to keep build times more manageable. (First I omitted LLDB as well, but that was requested back in #359.)
But since runner speeds have been increased since, I guess I could consider reenabling clang-tools-extra there as well, if there's a concrete demand for it. (I could also consider to only skip it from nightly builds, but perhaps it's not worth the complexity.)
I pushed a fix for this now in 9b18842, so the next release should include clang-tidy on unix as well.
There is talks about a LLVM 18.1.7 release happening this week, so in that case, there'll be a new release soon that will include these tools.
thanks. i use clang-tidy to analyze my code on macos. llvm from homebrew can analyze mac and linux code, but i don't know how to use it for windows. llvm-mingw's clang-tidy can.
The latest release, at https://github.com/mstorsjo/llvm-mingw/releases/tag/20240606, now should include clang-tidy in the unix packages too.
Thanks, it works. But I have problems when using it on macOS with cmake. cmake command is
cmake -GNinja -DCMAKE_TOOLCHAIN_FILE=llvm-mingw.cmake -DLLVM_MINGW=/Volumes/dev/llvm-mingw-20240606-ucrt-macos-universal -DCMAKE_CXX_CLANG_TIDY=/Volumes/dev/llvm-mingw-20240606-ucrt-macos-universal/bin/clang-tidy
Then I get build error:

I add --extra-arg=-v for clang-tidy, i.e. cmake -E __run_co_compile --tidy="/Volumes/dev/llvm-mingw/bin/clang-tidy;--extra-arg-before=--driver-mode=g++;--extra-arg=-v" --source=/tmp/tidy/main.cpp -- /Volumes/dev/llvm-mingw/bin/aarch64-w64-mingw32-clang++ -gcodeview -MD -MT CMakeFiles/tidy.dir/main.cpp.obj -MF CMakeFiles/tidy.dir/main.cpp.obj.d -o CMakeFiles/tidy.dir/main.cpp.obj -c /tmp/tidy/main.cpp

We can see the default target triple is arm64-apple-macosx14.0.0, and clang-tool is invoked but infact it does not exist, is it right? I change the triple /opt/homebrew/Cellar/cmake/3.29.0/bin/cmake -E __run_co_compile --tidy="/Volumes/dev/llvm-mingw/bin/clang-tidy;--extra-arg-before=--driver-mode=g++;--extra-arg=--target=x86_64-w64-windows-gnu;--extra-arg=-v" --source=/tmp/tidy/main.cpp -- /Volumes/dev/llvm-mingw/bin/aarch64-w64-mingw32-clang++ -gcodeview -MD -MT CMakeFiles/tidy.dir/main.cpp.obj -MF CMakeFiles/tidy.dir/main.cpp.obj.d -o CMakeFiles/tidy.dir/main.cpp.obj -c /tmp/tidy/main.cpp but still get an error because "c++/v1" is not included in -internal-isystem

So I have to add more options for clang-tidy or cmake, finally this works /opt/homebrew/Cellar/cmake/3.29.0/bin/cmake -E __run_co_compile --tidy="/Volumes/dev/llvm-mingw/bin/clang-tidy;--extra-arg-before=--driver-mode=g++;--extra-arg=--target=x86_64-w64-windows-gnu;--extra-arg=-v;--extra-arg=--sysroot=/Volumes/dev/llvm-mingw-20240606-ucrt-macos-universal/x86_64-w64-mingw32;--extra-arg=-I=/include/c++/v1" --source=/tmp/tidy/main.cpp -- /Volumes/dev/llvm-mingw/bin/aarch64-w64-mingw32-clang++ -gcodeview -MD -MT CMakeFiles/tidy.dir/main.cpp.obj -MF CMakeFiles/tidy.dir/main.cpp.obj.d -o CMakeFiles/tidy.dir/main.cpp.obj -c /tmp/tidy/main.cpp
Instead of specifying the libc++ include dir manually, pass -stdlib=libc++.
I haven't used clang-tidy myself, but I guess we'd need to provide wrappers that set these defaults, or use a toolchain file like in #430 to pass those parameters, if they get picked up from there and used with clang-tidy too.
-stdlib=libc++ works
