r/Compilers on Reddit: Setting up llvm toolchain with vscode on windows.

February 23, 2025 -

I want to develop C++ applications using LLVM toolchain on windows with vscode. Does it need mingw or visual studio 2022 for setup? I tried to run a simple c++ program yet it is taking forever to debug.

I have installed wsl2 and do all compilation/running inside. Vscode supports creating projects inside wsl, so it is a smooth experience. Plus installing llvm and using gcc is much simpler, since it is an actual linux system. You can also find files inside wsl from windows explorer and vice versa. For me it is the best of both worlds, but i know people that have trouble with setting up wsl or using something like docker and network stuff inside.

I am not using Windows but when I am writing C++ I use Zig to compile it since it is personal code and it is easy to set up. You can try it too.

If you would like to run the LLVM tests you will need Python. Version 3.8 and newer are known to work. You can install Python with Visual Studio 2019, from the Microsoft store or from the Python web site. We recommend the latter since it allows you to adjust installation options. You will need Git for Windows with bash tools, too.

r/vscode on Reddit: Using LLVM with VSCode on Windows

June 19, 2020 -

Greetings!

I decided to set up VSCode to be able to code in C++ and build my programs using LLVM. So I downloaded official binaries of LLVM 10.0 and installed it on my Windows system, but unfortunately there is no guide on how to make VSCode use LLVM to build projects. Official tutorials suggest using VS C++ compiler or GCC with MinGWx64 and no one seems to be using LLVM on windows for some reason.

I don't want using VS C++ compiler because it will consume too much of my disk space which I don't want to trade and I don't want GCC on MinGW, well, because of MinGW and all the workaround to install it and setup. LLVM seemed to be the easiest option since it has official installer and platform support.

What is the easiest way to setup VSCode for building projects with LLVM on Windows? Or is there a reason to not even try doing so - that'd explain why no one writes guides about that! If it's not recommended to try LLVM for Windows, then what's going to be the best option otherwise? I just want to compile my projects with all the default configurations, I don't care about optimizations and etc. since the projects are just me studying algorithms with C++.

VSCode is a code editor with bells on, not an IDE. It doesn't provide a build system of any sort. Instead, you configure it to launch whatever build system you use for your project. Learn how to write a simple makefile, and have vscode launch that.

Shouldn't you be using Visual Studio? Visual Studio Community 2019 is free as well.

On Windows, Clang is not self-sufficient, and is supposed to be used in combination with an other compiler: either MinGW (GCC) or MSVC. Clang is going to use the standard library (and other libraries/headers) of that compiler, since it doesn't ship with ones of its own.

If you want to use it with MSVC and have it installed, running clang-cl instead of cl should just work.

But since you mentioned VSC, I assume you don't want MSVC. Then...

If you want to use it with MinGW and have it installed, use clang --target=x86_64-w64-windows-gnu instead of gcc, and it should also just work. (That's assuming your MinGW produces 64-bit apps. Replace x86_64 with i686 if it's 32-bit.)

If you don't have MinGW yet, you can get a fresh version from MSYS2. Then you have an option to install their unofficial build of Clang instead of the regular one, which has an advantage of using --target=x86_64-w64-windows-gnu automatically (so you don't have to write it manually).

Install Clang using Visual Studio Installer.
(1) Open 'Visual Studio Installer'.
(2) Visual Studio Community 2022 -> click 'Modify'
(3) In the [Installation details] checkbox list, check 'C++ Clang tools for Windows'
(4) Install.
Add clang.exe (created by the above procedure) to the Path environment variable.
Now try clang --version in the terminal.

Great, you're good to go :)

Edit: If you didn't change the default installation path, clang.exe should likely be in C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\Llvm such as (for x64) C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\Llvm\x64\bin.

C - Solved - How to use or set Clang/LLVM/GCC compilers on VS Code? | The FreeBSD Forums

August 26, 2022 - Its just that I cannot compile/build simple "C" code to use clang/llvm on VS Code by default when clicking on the "play button" which is located at the top right on VS Code. Thanks for any advice. EDIT: I spent about 2 full days in figuring out how to get VS code to work as an IDE for c/c++ on FreeBSD 13.1 I am now able to compile OpenCV 4 projects using clang and debug using GDB on VS Code.
