Description

Hi all, I'm trying to build app with mediapipe for Hololens2 While it works fine on unity editor, it throws dll not found error on hololens2 that it cannot find mediapipe_c my guess is that mediapipe_c.dll is not UWP compatible ?

DllNotFoundException: Unable to load DLL 'mediapipe_c'. Tried the load the following dynamic libraries: Unable to load dynamic library 'mediapipe_c' because of 'C:\build\output\unity\unity\External\il2cpp\builds\external\baselib\Source\WinApi\Baselib_DynamicLibrary_WinApi.inl.h(36):Baselib_DynamicLibrary_OpenUtf16: Failed to open the requested dynamic library (0x06000000) - The specified module could not be found.

Thanks

I think it's because the DLL is not built for Windows ARM.

Thanks for you reply. app built fine for HoloLens May i know how to build dll for Windows ARM ? i'm using files from release section

[homuler]

I'm not sure if we can in the first place because the Tensorflow does not support Windows ARM AFAIK.
