Prebuilt clang does not have llvm core library(dll) for windows.

[codetronik]

Questions may not be appropriate for this, but they are related to ndk deployment.

I'm trying to build llvm pass for ndk with prebuilt clang.
For linux, we provide llvm library, but Windows doesn't have dll, so it's impossible to build a pass.
Even darwin includes dylib library.
It was built easily on Linux and mac.
Not for Windows in the plan?

you can check it at the link below.

Not something the NDK supports. You need to build your own toolchain. https://android.googlesource.com/toolchain/llvm_android/+/refs/heads/main/README.md has instructions for rebuilding our toolchain.

It doesn't work either. There is no code in do_build.py to create .dll.

def normalize_llvm_host_libs(install_dir: Path, host: hosts.Host, version: Version) -> None:
    if host.is_linux:
        libs = {'libLLVM': 'libLLVM-{version}git.so',
                'libclang': 'libclang.so.{version}git',
                'libclang-cpp': 'libclang-cpp.so.{version}git',
                'libc++': 'libc++.so.{version}',
                'libc++abi': 'libc++abi.so.{version}'
               }
    else:
        libs = {'libc++': 'libc++.{version}.dylib',
                'libc++abi': 'libc++abi.{version}.dylib'
               }
