Self-updating... I've managed a little forward and done following:
- Generate a cmake toolchain (using Magic Leap SDK v0.20.0: https://creator.magicleap.com/learn/guides/sdk-mabu-ref-build-and-link-libraries#build-libraries-with-cmake ) - Run cmake (which succeeds) with a bash script as following: rmdir build mkdir -p build cd build cmake ../.. \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_TOOLCHAIN_FILE=../magicleap.toolchain.cmake \ -DRUN_HAVE_POSIX_REGEX=0 \ -DRUN_HAVE_STD_REGEX=0 \ -DRUN_HAVE_STEADY_CLOCK=0 \ Now I'm attempting to build the "grpc_csharp_ext" library as in: make grpc_csharp_ext which fails, with error output as following: ...

Note "*error: instruction requires: neon*". I haven't figured out how to address this one and am actively looking for solution. Please let me know if you have any directions Thank you, Ryo On Monday, March 25, 2019 at 11:17:47 PM UTC-7, [email protected] wrote: > > I'm trying to make streaming speech recognition (Google.Cloud.Speech.V1) > work in Magic Leap app. > > > I've managed to make it work in Unity Editor (Windows x64) as in this > video: > https://twitter.com/ryoichirooka/status/1110313722826784768 > But once I build it straight into Magic Leap runtime, I'll get this error: > > grpc_csharp_ext.dll not found > > ... since this DLL in the project is built for Windows x64 runtime (which > I just copied & pasted from repo) which works in Editor but won't get > carried to Magic Leap runtime. > So I'm trying to build "grpc_csharp_ext.dll" for Magic Leap myself.
