[R-pkg-devel] stdio.h and assert.h not found on CRAN MacOS ARM64 machines

Never mind. The error has suddenly disappeared. So, I guess it was a temporary issue with the CRAN machine.

Hi all,

After submitting a package, I get errors for two specific CRAN checks (both MacOS ARM64 machines) where the install log (see below) tells me that the compiler cannot find 'stdio.h' and 'assert.h'. I've never had this issue before, and the package builds fine on the other CRAN machines (including the other MacOS machines). I suspect that there is an issue with these particular CRAN machines. Or am I missing something?

This is the problematic install log:

Cheers,

Pepijn
