编译和使用支持 arm64, armv7 机构的 dlib 静态库。

cd dlib/examples    
修改 CMakeLists.txt 注释掉 52 和 55 行（静态库中，不需要这个例子文件cpp）     
mkdir build      
cd build      
cmake .. -G Xcode

//build 目录下会生成 xcode 工程，设置 xcode 工程来编译目标库
打开 examples.xcodeproj
选中 target dlib
Build Settings -> Supported Platforms 设置为 iOS ，默认为 Mac
Build Settings -> Base SDK 设置为 iOS 11
Build Settings -> Build Active Architecture Only 设置为 NO，生成 fat 静态库

选中 Project -> info iOS Deployment Target 设置为 10.
选中 tool bar -> product -> scheme -> edit scheme -> Run -> info -> Build Config 设置为 release

点击编译

编译结果 7.3 MB
Architectures in the fat file: ../build/dlib_build/Release-iphoneos/libdlib.a are: armv7 arm64

dlib C++ library

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 for the main project documentation and API reference.

Compiling dlib C++ example programs

Go into the examples folder and type:

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:

mkdir build; cd build; cmake .. -DUSE_AVX_INSTRUCTIONS=1; cmake --build .

Doing so will make some things run faster.

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:

cmake .. -G "Visual Studio 14 2015 Win64" -T host=x64

Compiling your own C++ programs that use dlib

The examples folder has a CMake tutorial that tells you what to do. There are also additional instructions on the dlib web site.

Compiling dlib Python API

Before you can run the Python example programs you must compile dlib. Type:

python setup.py install

or type

python setup.py install --yes USE_AVX_INSTRUCTIONS

if you have a CPU that supports AVX instructions, since this makes some things run faster.

Running the unit test suite

Type the following to compile and run the dlib unit test suite:

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.

This library is licensed under the Boost Software License, which can be found in dlib/LICENSE.txt. The long and short of the license is that you can use dlib however you like, even in closed source commercial software.
