Cross-compiling for aarch64, fatal error: limits: No such file or directory

[sadilekivan]

I have a working build when compiling for x86_64, but my final intention is to cross-compile for a RaspberryPi.

Fedora 37 (nushell)
sudo dnf install opencv-devel, which installed the following:

Anything obvious I missed? I feel like I have all the dependencies I need.

I would guess that your cross-compile toolchain is not set up/installed properly. I have been successfully cross-building for RPi Zero although from the Gentoo system (using https://wiki.gentoo.org/wiki/Crossdev). This specific error message has already been reported several times, there is an issue for it: #322 Maybe you can find a workaround there?
