Same

please make sure that in your build environment cmake is installed+in the path.
also assert that it matches the required version from readme (3.22)

there is a issue #34 + PR for this problem already.

installed latest version of cmake and Clang

i first start the Developer Command Prompt for VS 2022
then i check cmake and clang (see screenshot)

then i start conda
conda activate bitnet-cpp

From your logoutput Command '['cmake', '-B', 'build', '-DBITNET_X86_TL2=ON', '-T', 'ClangCL']'
I can see that you are using ClangCL
ClangCL is the Clang compiler with a command-line interface compatible with Microsoft’s cl.exe (MSVC) compiler, which allows it to be used in environments typically meant for Visual Studio.

So please make sure that the Visual Studio clang compiler version is visible and installed:

(bitnet-cpp) C:\work\microsoft\BitNet>clang --version
clang version 17.0.3
Target: i686-pc-windows-msvc
Thread model: posix
InstalledDir: C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\Llvm\bin

Hope you can resolve the error with this information

Wait this project only works if you are using Visual Studio 2022? It doesn't work at all outside of it, like VSCode?

[bmerkle]

it is C/C++ code. You have to build and compile it with a compiler (e.g. clang or clang from Visual Studio).

you should check the README :-) https://github.com/microsoft/BitNet?tab=readme-ov-file#installation

[byjlw]

Let me clarify. Do i have to buy Visual studio Pro to use this library or can i use clang and CMAKE directly?
I read the readme. I don't want to buy visual studio and have clang and CMAKE installed on my machine, so i can't follow the steps to the T.

[grctest]

I used the community version of visual studio, needed to add 2 extensions to enable building, then used conda and followed the readme.

I got similar errors to you when I tried using vs code insiders & venv

Now it works for me
