11_CAMERA_OBJECT_IDENTIFICATION

In the step4 ‘Bulid and run the sample with the following commands’
After I typed the command ‘make’, it warned that ‘…/Rules.mk:37: ***Please specify which ARM ABI platform you are compiling for.’
Could anyone solve this problem?
Thanks!

Hi,
You need to set

$ export TEGRA_ARMABI=aarch64-linux-gnu

Please follow document to set up the environment:
