在 Windows 上为 Android 设置 Dlib
Setting up Dlib for Android on Windows
我正尝试按照本教程 https://github.com/Luca96/dlib-for-android 在 windows 的 android 工作室中设置 dlib。我已经更改了各种变量的路径，但得到了同样的错误。我不需要 opencv 只需要 dlib。 Opencv 已经设置好并正常工作。
我用 -DCMAKE_MAKE_PROGRAM=C:\Users\computer\AppData\Local\Android\Sdk\cmake.10.2.4988404\bin\ninja.exe 替换了 -GNinja，但仍然出现错误。
使用 android studio 设置 dlib 的任何替代过程也将有效。
我根据提供的示例自定义 Power Shell 脚本：

EDIT: Use DLIB master from Github instead of 19.19 from their website to avoid errors with OpenCV. Change the paths accordingly, set dlib-19.19 to dlib-master where applicable.
我能够通过对路径和标志进行一些更改来编译 dlib。一个很大的变化是包括两个标志，
-GNinja -DCMAKE_MAKE_PROGRAM="C:\Users\computer\AppData\Local\Android\Sdk\cmake.10.2.4988404\bin\ninja.exe"
我将最新的 dlib(19.19) 提取到桌面并设置了 cmake、NDK、lldb。仅为 x86_64 编译，
C:\Users\computer\AppData\Local\Android\Sdk\cmake.10.2.4988404\bin\cmake.exe -DBUILD_SHARED_LIBS=1 -DCMAKE_TOOLCHAIN_FILE="C:\Users\computer\AppData\Local\Android\Sdk\ndk.0.6113669\build\cmake\android.toolchain.cmake" -DANDROID_NDK="C:\Users\computer\AppData\Local\Android\Sdk\ndk.0.6113669" -GNinja -DCMAKE_MAKE_PROGRAM="C:\Users\computer\AppData\Local\Android\Sdk\cmake.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"
运行 将上面的代码粘贴到 power shell 中。它将在 dlib 文件夹中生成 libdlib.so。

将上述代码保存到扩展名为 setup1.ps1 的强大 shell 文件中。上面的代码应该在每个平台文件夹的 dlib-19.19/dlib/build 文件夹中生成 libdlib.so 文件。
为了运行代码先以管理员身份打开电源shell。接下来，使用 set-location C:\Users\computer\Desktop\dlib-19.19。这里使用 Set-ExecutionPolicy RemoteSigned 并按 A 可以执行 powershell 代码。完成后（libdlib.so 生成并复制）使用 Set-ExecutionPolicy Restricted.
通过将 & "C:\Users\computer\Desktop\setup1.ps1" 粘贴到 shell 中，运行 幂 shell 代码。编译需要一些时间，编译后它会将不同平台的 headers 和 libdlib.so 复制到 android studio 项目文件夹，如上面脚本中的变量 $PROJECT_PATH 所示。
@B200011011 解决方案对我不起作用。我必须更正一些输出目录才能使其在 windows 10 PowerShell 上运行。
这是更新后的代码：

当您 运行 .ps1 PowerShell 脚本时，您可能会收到消息说“.ps1 未经过数字签名。该脚本不会在系统上执行。”
要修复它，您必须 运行 下面的命令 运行 Set-ExecutionPolicy 并更改执行策略设置。
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
我正尝试按照本教程 https://github.com/Luca96/dlib-for-android 在 windows 的 android 工作室中设置 dlib。我已经更改了各种变量的路径，但得到了同样的错误。我不需要 opencv 只需要 dlib。 Opencv 已经设置好并正常工作。
我用 -DCMAKE_MAKE_PROGRAM=C:\Users\computer\AppData\Local\Android\Sdk\cmake.10.2.4988404\bin\ninja.exe 替换了 -GNinja，但仍然出现错误。
使用 android studio 设置 dlib 的任何替代过程也将有效。
我根据提供的示例自定义 Power Shell 脚本：

EDIT: Use DLIB master from Github instead of 19.19 from their website to avoid errors with OpenCV. Change the paths accordingly, set
dlib-19.19todlib-masterwhere applicable.
我能够通过对路径和标志进行一些更改来编译 dlib。一个很大的变化是包括两个标志，
-GNinja -DCMAKE_MAKE_PROGRAM="C:\Users\computer\AppData\Local\Android\Sdk\cmake.10.2.4988404\bin\ninja.exe"
我将最新的 dlib(19.19) 提取到桌面并设置了 cmake、NDK、lldb。仅为 x86_64 编译，
C:\Users\computer\AppData\Local\Android\Sdk\cmake.10.2.4988404\bin\cmake.exe -DBUILD_SHARED_LIBS=1 -DCMAKE_TOOLCHAIN_FILE="C:\Users\computer\AppData\Local\Android\Sdk\ndk.0.6113669\build\cmake\android.toolchain.cmake" -DANDROID_NDK="C:\Users\computer\AppData\Local\Android\Sdk\ndk.0.6113669" -GNinja -DCMAKE_MAKE_PROGRAM="C:\Users\computer\AppData\Local\Android\Sdk\cmake.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"
运行 将上面的代码粘贴到 power shell 中。它将在 dlib 文件夹中生成 libdlib.so。

将上述代码保存到扩展名为 setup1.ps1 的强大 shell 文件中。上面的代码应该在每个平台文件夹的 dlib-19.19/dlib/build 文件夹中生成 libdlib.so 文件。
为了运行代码先以管理员身份打开电源shell。接下来，使用 set-location C:\Users\computer\Desktop\dlib-19.19。这里使用 Set-ExecutionPolicy RemoteSigned 并按 A 可以执行 powershell 代码。完成后（libdlib.so 生成并复制）使用 Set-ExecutionPolicy Restricted.
& "C:\Users\computer\Desktop\setup1.ps1" 粘贴到 shell 中，运行 幂 shell 代码。编译需要一些时间，编译后它会将不同平台的 headers 和 libdlib.so 复制到 android studio 项目文件夹，如上面脚本中的变量 $PROJECT_PATH 所示。
@B200011011 解决方案对我不起作用。我必须更正一些输出目录才能使其在 windows 10 PowerShell 上运行。
这是更新后的代码：
