# <div align="center"><strong>Dlib</strong></div>
Dlib is a modern C++ toolkit containing machine learning algorithms and tools for creating complex software in C++ to solve real world problems. See [http://dlib.net](http://dlib.net) for the main project documentation and API reference.
## 1 简介
Dlib 是一个现代化的 C++ 工具包，包含机器学习算法和用于创建复杂 C++ 软件的工具，旨在解决现实世界中的问题。
Finally, Visual Studio users should usually do everything in 64bit mode. By default Visual Studio is 32bit, both in its outputs and its own execution, so you have to explicitly tell it to use 64bits. Since it's not the 1990s anymore you probably want to use 64bits. Do that with a cmake invocation like this:
```bash
cmake .. -G"Visual Studio 14 2015 Win64"-Thost=x64
```
#### 2.2.1 编译环境准备
## Compiling your own C++ programs that use dlib
提供基于 fastpt 不转码编译：
The examples folder has a [CMake tutorial](https://github.com/davisking/dlib/blob/master/examples/CMakeLists.txt) that tells you what to do. There are also additional instructions on the [dlib web site](http://dlib.net/compile.html).
Alternatively, if you are using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager you can download and install dlib with CMake integration in a single command:
Note that on windows your compiler might put the test executable in a subfolder called `Release`. If that's the case then you have to go to that folder before running the test.
- 执行下面的命令测试组件：
```bash
source /usr/local/bin/fastpt -E
cd python_examples
python svm_rank.py
python svm_struct.py
```

## Compiling dlib C++ example programs
Go into the examples folder and type:
```bash
mkdir build;cd build; cmake .. ; cmake --build .
```
That will build all the examples.
If you have a CPU that supports AVX instructions then turn them on like this:

```
## Compiling dlib Python API
Before you can run the Python example programs you must compile dlib. Type:
```bash
python setup.py install
```
## Running the unit test suite
Type the following to compile and run the dlib unit test suite:
```bash
cd dlib/test
mkdir build
cd build
cmake ..
cmake --build.--config Release
./dtest --runall
```
Note that on windows your compiler might put the test executable in a subfolder called `Release`. If that's the case then you have to go to that folder before running the test.
