@ -31,13 +31,6 @@ In order to build llama.cpp you have four different options.
- For `Q4_0_4_4` quantization type build, add the `GGML_NO_LLAMAFILE=1` flag. For example, use `make GGML_NO_LLAMAFILE=1`.
- For faster compilation, add the `-j` argument to run multiple jobs in parallel. For example, `make -j 8` will run 8 jobs in parallel.
- For faster repeated compilation, install [ccache](https://ccache.dev/).
- For Windows:
- Install cmake e.g. via `winget install cmake`:
- As alternative to the w64devkit mentioned in "using make" above, install MSVC (e.g. via Visual Studio 2022 Community Edition).
- For Windows on ARM you need MSVC installed and _additonally_:
- Install [clang via LLVM for woa64](https://releases.llvm.org) to enable better ARM optimizations (clang needs the MSVC backend).
- For using clang, the first build step needs to be `cmake --preset arm64-windows-llvm-release` (instead of the `cmake -B ...` which defaults to MSVC).
- Note: Building for ARM can also be done just with MSVC (without installing clang or using the preset), but this does not support e.g. the accelerated Q_4_0_4_4/Q_4_0_4_8 kernels (a 2-2.5x prompt-processing speed improvement on the CPU), because the MSVC frontend cannot inline ARM assembly-code.
- For debug builds, run `make LLAMA_DEBUG=1`
- Using `CMake`:

- Building for Windows on ARM:
- Install MSVC / Visual Studio 2022 (VS2022), e.g. via the [Community Edition](https://visualstudio.microsoft.com/de/vs/community/). The latest VS2022 automatically installs the required CMake and Ninja tools.
- Also install the clang compiler + tools (LLVM). Either via direct download [clang/LLVM for Windows](https://github.com/llvm/llvm-project/releases/) (use the file "LLVM-\<version\>-woa64.exe"), or alternatively install via the [Chocolatey (choco) package manager](https://chocolatey.org/install) with `choco install llvm`. This LLVM for Windows requires an installed MSVC, and therefore always use it in a Develoer Command Prompt / PowerShell.
- Then build _in a Developer Command Prompt / PowerShell for VS2022_ with:
```bash
cmake --preset arm64-windows-llvm-release
cmake --build build-arm64-windows-llvm-release
```
