A cran "special check" to identify packages with problems specifically on arm64 linux.
We check CRAN packages on both amd64 and arm64 runners using exactly the same setup. We flag packages that show a WARNING or ERROR on arm64 but not on amd64.
The checks run in the rcheckserver container which has the same system libraries as CRAN Debian servers.
This is a community project and also serves as a template to use GitHub actions for running custom CRAN special checks. For problems or suggestions please open an issue in this repository (no need to email CRAN).
