just a follow up, rpi os 64bit - unable to compile xnnpack rpi os 32bit - unable to compile xnnpack due to binutils ubuntu 22.04 32bit - compiles xnnpack

hi,

I just tried with a semi-fresh install of Raspberry Pi OS Lite 64-bit, and it works.

Can you do a test with a fresh install of this OS?

Thanks, --Vito

you are correct, I am able to compile XNNpack with RpiOS 64bit if you don't do apt update && apt upgrade since that will update the kernel and break compile.

hi,

I did an update, an upgrade, a reboot and a full rebuild of XnnPack, and it works...

The problem is elsewhere.

Can you do a test with a fresh install of Raspberry Pi OS Lite 64-bit, and let me know?

thanks, Vito

i did a fresh install of raspberry pi os lite 64bit, here are the steps i took.

sudo apt update && sudo apt upgrade -y
sudo raspi-config -> performace -> gpu 16mb
sudo reboot

followed your instructions to compile XNNPACK

modified dphys memory from 100mb to 512mb to compile OnnxStream

each step is about 26mins

I'm running into similar problems, would you be willing to share exact OS versions/image hashes and the XNNPACK git commit hash that led to a successful compile?

Thanks a lot! Will report back if I run into failures.

faruk@raspberrypi:~/OnnxStream/src/build $ cmake -DMAX_SPEED=ON -DXNNPACK_DIR= /home/faruk/XNNPACK .. I wrote this line but I still got this error "Please specify XNNPACK_DIR." What should I do?

[vitoplantamura]

@ofarukdemirtas, please remove the space after "-DXNNPACK_DIR="
