Actually I’m trying to build clazy by the KDE project. For that I need a build of clang.
I followed the instructions described here: GitHub - KDE/clazy: Qt-oriented static code analyzer based on the Clang framework
I cloned the llvm-project repo and checked out the tag llvmorg-19.1.5. For the build I’m using Visual Studio 2022. I have Python 3.12 installed on the build system. I run my build in a Developer Command Prompt for VS 2022.
I used the following command to configure and generate the makefiles for clang:
cmake -DCMAKE_INSTALL_PREFIX=D:\ws\llvm-install\ -DLLVM_EXPORT_SYMBOLS_FOR_PLUGINS=ON -DLLVM_INCLUDE_EXAMPLES=OFF -DLLVM_TARGETS_TO_BUILD="X86" -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" -DCMAKE_BUILD_TYPE=Release -G "Ninja" ..\llvm-project
While building I have to issues.
Since I’m using Python 3.12, I got a lot of SyntaxWarnings from llvm\utils\extract_symbols.py, e.g.:
D:\ws\llvm-project\llvm\utils\extract_symbols.py:172: SyntaxWarning: invalid escape sequence '\d'
match = re.match("(\d+)(.+)", arg)
But more importantely, I got a linker error when the library CTTestTidyModule.dll is getting linked:

Can somebody please help me.
