I observe the same error on a raspberry pi 3A PLUS Rev 1.0 with Raspian stretch.

I get the error during the ninja build of NNPACK-darknet. Therefore I creaeted a ticket at that repo:

I am working with an RPI4. I have followed all the steps and installed the dependencies but when I execute the step $NINJA_PATH/ninja in "Install NNPACK-darknet" it gives me the same error as @rahmanzf.

Any solution? Thanks in advance.

I am having the same error with RPI4 (4 Gb RAM),

Any tip? thanks!

As said here https://summerbright.xyz/Maratyszcza/NNPACK/issues/187#issuecomment-618771831, the rules that use confu are deprecated. I would recommend you to try the cmake building instructions that you may find in the original NNPACK repo.

I have merged digitalbrain79/NNPACK-darknet with Maratyszcza/NNPACK, here. It can be built using cmake without any errors.
