I am developing a tool using the clang library on Linux and I would like to port this tool to Windows.
On Linux, I can install Clang from the LLVM repositories using apt-get clang-6.0-dev and simply link my tool with -lclang. I do not need to compile LLVM and Clang myself.
Is there a way to do something similar on Windows, or do I need to compile the Clang library myself?
All of the Clang-related posts I could find are about using clang as a tool, not as a library.
I have installed the pre-build executables for Clang and LLVM from the LLVM website, and these work nicely in combination with mingw. However, the download for Windows does not seem to include the Clang library as a separate file (DLL), and linking with -lclang results in a linker error.
If there is no pre-built library for Windows, what is the best way to proceed, preferably using mingw and not MSVC?

Answer 1

There are pre-built LLVM/clang binaries on Zig's github page:
https://github.com/ziglang/zig/wiki/Building-Zig-on-Windows
You can find libclang.dll in the bin folder.
The currently available versions are:
llvm+clang-6.0.0-win64-msvc-release.tar.xz
llvm+clang-7.0.0-win64-msvc-release.tar.xz
llvm+clang-8.0.0-win64-msvc-release.tar.xz
llvm+clang-9.0.0-win64-msvc-release.tar.xz
llvm+clang+lld-10.0.0-x86_64-windows-msvc-release-mt.tar.xz
There are also detailed build instructions, here.

For anyone coming to this question that's just looking to install libclang on their system, the choco llvm package appears to install libclang correctly. I can't speak to whether this is adequate for actually linking against this library for C/C++, but it worked for my case.
Just run this in an elevated command prompt or powershell:
choco install llvm
You may need to run refreshenv or open a new console for tools to pick this up.
In my case, and to help with future googlers (since I couldn't find a simple answer elsewhere) my issue was specifically while trying to compile a Rust project that made use of the onig_sys crate:
Compiling onig_sys v69.2.0
