# Tengine C Classification X86版本完整示例
## 环境
**System**: Ubuntu20.04
**CMAKE**: 3.16.3
## 准备
1. 把[第0篇-Tengine X86版本编译](https://zhuanlan.zhihu.com/p/181579203)中编译好的so和头文件复制到项目目录中的tengine目录
2. 把[Tengine/examples/common](https://github.com/OAID/Tengine/tree/tengine-lite/examples/common)中部分文件放入common目录
3. 把[模型仓库](https://github.com/OAID/Tengine/tree/tengine-lite/examples#%E6%A8%A1%E5%9E%8B%E4%BB%93%E5%BA%93)的mobilenet.tmfile模型放到models目录，cat.jpg图片放到images目录
4. 把[tm_classification.c](https://github.com/OAID/Tengine/blob/tengine-lite/examples/tm_classification.c)文件放到src目录
此时目录结构应该是这样
```
├── images
│ └── cat.jpg
├── models
│ └── mobilenet.tmfile
├── src
│ ├── common
│ │ ├── common.h
│ │ ├── stb_image.h
│ │ ├── stb_image_write.h
│ │ ├── tengine_operations.c
│ │ └── tengine_operations.h
│ └── tm_classification.c
└── tengine
├── include
│ └── tengine
│ ├── c_api.h
│ └── defines.h
└── lib
└── libtengine-lite.so
```
## 编写 CMakeLists.txt
```cmake
cmake_minimum_required(VERSION 3.10)
project(tm_classification)
set(CMAKE_CXX_STANDARD 11)
include_directories(tengine/include/ src/common/)
add_library(tengine SHARED IMPORTED)
set_target_properties(tengine PROPERTIES IMPORTED_LOCATION ${CMAKE_SOURCE_DIR}/tengine/lib/libtengine-lite.so)
add_executable(tm_classification src/tm_classification.c "src/common/tengine_operations.c" )
target_link_libraries(tm_classification -lm tengine)
```
## 编译
```bash
mkdir build
cd build
cmake ..
make -j`nproc`
```
## 测试
```
./build/tm_classification -m ./models/mobilenet.tmfile -i ./images/cat.jpg
```
输出
```
