Building Clazy

Monday, February 03, 2025

Following https://github.com/KDE/clazy?tab=readme-ov-file#windows

I checked out llvm-19.1.7. build llvm takes 4 hours…

install llvm

installed llvm via

cmake --install .

and add bin-path to Path via the shortcut

rundll32 sysdm.cpl,EditEnvironmentVariables

build clazy

cmake -DCMAKE_INSTALL_PREFIX=C:\src\clazy_install -DLLVM_ROOT=C:C:\src\llvm-project-install\ -DCMAKE_BUILD_TYPE=Release -G "Ninja" -B build

However I get weird error:

C:\src\clazy [(1.13)]> cmake --build build

collect2.exe: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.

I retried but the same error.

Then I tried it using msys2 but get the error “llvm-config” not found. weired..

rebuild llvm was certainly not an option.

There are several files: Replacement.cpp, ASTReader.cpp, and ParseObjc.cpp.

I find them using fzf and edited them:

Then I build llvm incrementally and installed it, then run ninja again in clazy build directory, but it’s the same error…

rebuild clazy

I think there might be a mix for scoop llvm and custom built llvm. so I uninstalled llvm again (it was used in llvm build and get re-installed..), then I deleted the build directory, and re-run the cmake command:

cmake -DCMAKE_INSTALL_PREFIX=C:\src\clazy_install -DCLANG_LIBRARY_IMPORT=C:\src\llvm-project-install\lib\libclang.dll.a -DCMAKE_BUILD_TYPE=Release -G "Ninja" -B build -DLLVM_ROOT=C:\src\llvm-project-install\

however the error was still the same…

rebuild clazy again

This time I switched to master branch. it’s still the same error. I give up.

rebuild llvm

So.. I get here.

rerun:

cmake -DCMAKE_INSTALL_PREFIX=C:\src\llvm-project-install -DLLVM_EXPORT_SYMBOLS_FOR_PLUGINS=ON -DLLVM_INCLUDE_EXAMPLES=OFF -DLLVM_TARGETS_TO_BUILD="X86" -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" -G "Ninja" ..\llvm-project\llvm\ -DCMAKE_CXX_COMPILER=g++ -DCMAKE_C_COMPILER=gcc -DCMAKE_ASM_COMPILER=gcc -DCMAKE_BUILD_TYPE="Release"

then:

ninja -j1 -k0

however it still failed.
