libclang debug libs are missing

Cobra91151

Hello!

I would like to build Qt 6 - debug and release mode for Visual Studio 2019 compiler. From the docs: https://wiki.qt.io/Building_Qt_6_from_Git, it requires the libclang libraries, which can be found here: https://download.qt.io/development_releases/prebuilt/libclang/, but it only available for release mode build. Where I can find the libclang source code or libclang prebuilt libs for debug mode? Also, there are a lot of clang libs available here: https://github.com/llvm/llvm-project/releases/tag/llvmorg-15.0.6, but I am no sure which are suitable for Qt 6? Thank you.

Hello!

I have built LLVM and Clang successfully. Here are my instructions:

Download llvm-project-llvmorg-15.0.6.zip from https://github.com/llvm/llvm-project
Use this command to build LLVM and Clang: cmake -B build -G "Ninja" -DCMAKE_BUILD_TYPE="Debug" -DLLVM_USE_CRT_DEBUG=MDd -DLLVM_ENABLE_PROJECTS="clang" -DLIBCLANG_BUILD_STATIC=ON -DCMAKE_INSTALL_PREFIX="C:\\LLVM\\msvc2019\\x64\\debug" -S C:\\llvm-project-llvmorg-15.0.6\\llvm
cd build
cmake --build .
cmake --install .
The same will work for Release type as well just change the -DCMAKE_BUILD_TYPE="Debug" and -DLLVM_USE_CRT_DEBUG=MDd to -DCMAKE_BUILD_TYPE="Release" and -DLLVM_USE_CRT_DEBUG=MD. The issue is resolved. Thank you.
