# CPU部署库编译

FastDeploy当前在CPU支持后端引擎如下

| 后端 | 平台  | 支持模型格式 | 说明 |
| :--- | :---- | :----------- | :--- |
| Paddle&nbsp;Inference | Windows(x64)<br>Linux(x64) | Paddle | 编译开关`ENABLE_PADDLE_BACKEND`为ON或OFF控制, 默认OFF |
| ONNX&nbsp;Runtime | Windows(x64)<br>Linux(x64/aarch64)<br>Mac(x86/arm64) | Paddle/ONNX | 编译开关`ENABLE_ORT_BACKEND`为ON或OFF控制，默认OFF |
| OpenVINO | Windows(x64)<br>Linux(x64)<br>Mac(x86) | Paddle/ONNX | 编译开关`ENABLE_OPENVINO_BACKEND`为ON或OFF控制，默认OFF |

## C++ SDK编译安装

### Linux & Mac

Linux上编译需满足
- gcc/g++ >= 5.4(推荐8.2)
- cmake >= 3.18.0

```bash
git clone https://github.com/PaddlePaddle/FastDeploy.git
cd FastDeploy
mkdir build && cd build
cmake .. -DENABLE_ORT_BACKEND=ON \
         -DENABLE_PADDLE_BACKEND=ON \
         -DENABLE_OPENVINO_BACKEND=ON \
         -DCMAKE_INSTALL_PREFIX=${PWD}/compiled_fastdeploy_sdk \
         -DENABLE_VISION=ON \
         -DENABLE_TEXT=ON
make -j12
make install
```

### Windows

Windows编译需要满足条件

- Windows 10/11 x64
- Visual Studio 2019

在Windows菜单中，找到`x64 Native Tools Command Prompt for VS 2019`打开，执行如下命令

```bat
git clone https://github.com/PaddlePaddle/FastDeploy.git
cd FastDeploy
mkdir build && cd build
cmake .. -G "Visual Studio 16 2019" -A x64 ^
         -DENABLE_ORT_BACKEND=ON ^
         -DENABLE_PADDLE_BACKEND=ON ^
         -DENABLE_OPENVINO_BACKEND=ON ^
         -DENABLE_VISION=ON ^
         -DENABLE_TEXT=ON ^
         -DCMAKE_INSTALL_PREFIX="D:\Paddle\compiled_fastdeploy" ^
msbuild fastdeploy.sln /m /p:Configuration=Release /p:Platform=x64
msbuild INSTALL.vcxproj /m /p:Configuration=Release /p:Platform=x64
```

编译完成后，即在`CMAKE_INSTALL_PREFIX`指定的目录下生成C++推理库

如您使用CMake GUI可参考文档[Windows使用CMakeGUI + Visual Studio 2019 IDE编译](../faq/build_on_win_with_gui.md)

## Python编译安装

编译过程同样需要满足
- gcc/g++ >= 5.4(推荐8.2)
- cmake >= 3.18.0
- python >= 3.6

Python打包依赖`wheel`，编译前请先执行`pip install wheel`

所有编译选项通过环境变量导入

### Linux & Mac

```bash
git clone https://github.com/PaddlePaddle/FastDeploy.git
cd FastDeploy/python
export ENABLE_ORT_BACKEND=ON
export ENABLE_PADDLE_BACKEND=ON
export ENABLE_OPENVINO_BACKEND=ON
export ENABLE_VISION=ON
export ENABLE_TEXT=ON

python setup.py build
python setup.py bdist_wheel
```

### Windows

编译过程同样需要满足
- Windows 10/11 x64
- Visual Studio 2019
- python >= 3.6

在Windows菜单中，找到`x64 Native Tools Command Prompt for VS 2019`打开，执行如下命令

```bat
git clone https://github.com/PaddlePaddle/FastDeploy.git
cd FastDeploy/python
set ENABLE_ORT_BACKEND=ON
set ENABLE_PADDLE_BACKEND=ON
set ENABLE_OPENVINO_BACKEND=ON
set ENABLE_VISION=ON
set ENABLE_TEXT=ON

python setup.py build
python setup.py bdist_wheel
```

编译完成即会在`FastDeploy/python/dist`目录下生成编译后的`wheel`包，直接pip install即可

编译过程中，如若修改编译参数，为避免带来缓存影响，可删除`FastDeploy/python`目录下的`build`和`.setuptools-cmake-build`两个子目录后再重新编译
