Current CRAN failures and potential removal

We've received:

Dear maintainers,

This concerns the CRAN packages

maintained by one of you:

We have asked for an update fixing the check problems shown at https://www.google.com/url?q=https://cran.r-project.org/web/checks/check_results_rstanarm.html&source=gmail-imap&ust=1696482614000000&usg=AOvVaw2ETYP7D0zxfNXQys5qDI7v with no update from the maintainer thus far.

Thus, package rstanarm is now scheduled for archival on 2023-10-12, and archiving this will necessitate also archiving its CRAN strong reverse dependencies.

Please negotiate the necessary actions.

The CRAN Team

One issue is "Check: for GNU extensions in Makefiles " and another is related to compiler issues (?). There is also a check specific to M1 macs.

Is there anything that we can do? If you need mac hardware to test, I can run things for you.

It would be good to know if fixes are in progress.

Start with the linked CRAN check results for rstanarm and identify the GNU Makefile, compiler, and M1 Mac failures mentioned in the issue. Review the corresponding build configuration and reproduce the checks on an affected platform if available; done means the reported CRAN checks pass and the archival risk is addressed.
