try building esp32s3-devkit:knsh on macOS.
it uses kconfig-merge, which internally uses cp -T, which is not available for non-gnu cp.

Hi @yamt. This is a kconfig-merge issue and not exactly a ESP32S3 one, but I get the problem.
Installing coreutils may solve your problem. You would have access to the expected cp options.

Did you follow those steps on NuttX installing guide for MacOS?

iirc, this kconfig-merge fork is maintained by nuttx. thus i filed this issue here.

IMO, nuttx should not require coreutils.

no.
(well, i might have followed an old version of these instructions. i don't remember.)

This is not an issue of ESP32-S3, but for NuttX. Did you test with kconfiglib too?

How did the CI test on MacOS?
