I tried to build NNPACK for ARM Neon. I used 748b9e1 based on a previous issue comment. I kept having the following build error. I am not sure if this is a problem from my configuration or the code. Does anyone have built for neon successfully?

Yes, I regularly build NNPACK for ARM/ARM64.

Do you build on an ARM system? arm_neon.h is the standard header for Neon intrinsics, it should have been installed with your compiler.

Got it. Thanks! Let me try and fix this now.

@Maratyszcza How to do cross-compile for ARM? I dont quite understand build.ninja to change the configuration. Any guidelines on how to specify compiler when build?

Maratyszcza commented 7 years ago

Cross-compilation for ARM/Linux is not supported.
