### llama.cppのビルド

```bash
mkdir -p ~/git
cd ~/git
git clone https://github.com/ggml-org/llama.cpp
cd llama.cpp
sudo apt update
sudo apt install libcurl4-openssl-dev libssl-dev -y
rm -rf build
mkdir -p build
cmake -B build -DGGML_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES="121" -DBUILD_SHARED_LIBS=OFF
cmake --build build --config Release -j 20 --clean-first
```

```bash
$ ./build/bin/llama --version
version: 0.1.0-dev (build 10454, commit 4df29be4f)
built with GNU 13.3.0 for Linux aarch64
```

### サービスの登録と起動

`--chat-template-file `に以下のjijaテンプレートを設定しないと、Claude Codeからは次のエラーメッセージが出ました。
