Yes, I forgot to mention this is using the latest from https://github.com/Arm-software/armnn.

Hi Nicolas,
That's not supposed to happen! With the way it's currently set up, the CpuRef backend should always be present, and it's just written in C++ so it can't be 'unsupported'.
Was this with a master revision? It might be a recent regression.
All the best,
Matthew

I followed the instructions here:
https://developer.arm.com/technologies/machine-learning-on-arm/developer-mat...
Both ArmCL and ArmNN are configured for arm64-v8a and neon.
I ran the UnitTests program which reported:
Running 842 test cases... *** No errors detected
However, when testing with SimpleSample.cpp, I get this:
Please enter a number: 42 [2019-02-06 17:11:57.624459] [0x0000ffffa612a000] [info] ArmNN v20181100 [2019-02-06 17:11:57.624661] [0x0000ffffa612a000] [warning] ERROR: None of the preferred backends [CpuRef ] are supported. Current platform provides [] Segmentation fault
It isn't clear to me what might be wrong by looking at the source code.
Any hint would be appreciated.
