Настройка Dlib для Android studio

Question

Я пытаюсь настроить dlib в android студии в windows, следуя этому уроку, https://github.com/Luca96/dlib-for-android. Я изменил путь к различным переменным, но получил ту же ошибку. Мне не нужен opencv просто dlib. Opencv уже настроен и работает правильно.

Я заменил -GNinja на -DCMAKE_MAKE_PROGRAM=C:\Users\computer\AppData\Local\Android\Sdk\cmake\3.10.2.4988404\bin\ninja.exe и все еще получаю ошибку.

Любая альтернативная процедура для установки dlib с android studio будет также работает.

Мой пользовательский сценарий Power Shell на основе предоставленного образца:

Answer 1

РЕДАКТИРОВАТЬ: Используйте мастер DLIB из Github вместо 19.19 с их веб-сайта, чтобы избежать ошибок с OpenCV. Измените пути соответственно, установите dlib-19.19 на dlib-master, где это применимо.

Я смог скомпилировать dlib, внеся некоторые изменения в путь и флаги. Большим изменением стало включение обоих флагов:

-GNinja -DCMAKE_MAKE_PROGRAM="C:\Users\computer\AppData\Local\Android\Sdk\cmake\3.10.2.4988404\bin\ninja.exe"

Я извлек последнюю dlib(19.19) на рабочий стол, а также настроил cmake, NDK, lldb. Компиляция только для x86_64,

C:\Users\computer\AppData\Local\Android\Sdk\cmake\3.10.2.4988404\bin\cmake.exe -DBUILD_SHARED_LIBS=1 -DCMAKE_TOOLCHAIN_FILE="C:\Users\computer\AppData\Local\Android\Sdk\ndk\21.0.6113669\build\cmake\android.toolchain.cmake" -DANDROID_NDK="C:\Users\computer\AppData\Local\Android\Sdk\ndk\21.0.6113669" -GNinja -DCMAKE_MAKE_PROGRAM="C:\Users\computer\AppData\Local\Android\Sdk\cmake\3.10.2.4988404\bin\ninja.exe" -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS=-std=c++11 -frtti -fexceptions -DANDROID_ABI=x86_64 -DANDROID_PLATFORM=android-24 -DANDROID_TOOLCHAIN=clang -DANDROID_STL=c++_shared -DANDROID_CPP_FEATURES=rtti exceptions "C:\Users\computer\Desktop\dlib-19.19\CMakeLists.txt"

Запустите указанный выше код, вставив его в Power Shell. Он сгенерирует libdlib.so в папке dlib.

Сохраните приведенный выше код в файл Power Shell с расширением setup1.ps1. Приведенный выше код должен генерировать файл libdlib.so внутри папки dlib-19.19/dlib/build для каждой папки платформы.

Для запуска кода сначала откройте Power Shell от имени администратора. Далее используйте set-location C:\Users\computer\Desktop\dlib-19.19. Здесь используйте Set-ExecutionPolicy RemoteSigned и нажмите A, чтобы иметь возможность выполнять код powershell. После того, как все сделано (libdlib.so сгенерировано и скопировано), используйте Set-ExecutionPolicy Restricted.

Запустите код Power Shell, вставив & "C:\Users\computer\Desktop\setup1.ps1" в оболочку. Компиляция займет некоторое время и после компиляции скопирует заголовки и libdlib.so для другой платформы в папку android студийного проекта, как в переменной $PROJECT_PATH в приведенном выше сценарии.
