rstan and EpiNow2

[TimTaylor]

Any chance you can poke rstan and then EpiNow2 and see if they will build.

No problem if not - I know stan can be tricky.

Mmmh, both fail with:

/usr/local/lib/R/library/StanHeaders/include/stan/math/prim/core/init_threadpool_tbb.hpp:9:10: fatal error: tbb/tbb_stddef.h: No such file or directory
    9 | #include <tbb/tbb_stddef.h>
      |          ^~~~~~~~~~~~~~~~~~

in F40 and rawhide, where tbb 2021 is available. See e.g. https://copr.fedorainfracloud.org/coprs/iucar/cran/build/7475986/. This should be fixed in StanHeaders.

Added a comment in stan-dev/rstan/issues/1041

Cheers for following up. I'd somewhat optimistically seen a new stanHeaders land and thought that would have solved it 😅

[Enchufa2]

It turns out that tbb autodetection was disabled in RcppParallel RcppCore/RcppParallel/issues/216, and this triggered the other issues. I added a workaround for now, and rstan has been successfully rebuilt. All the others dependent on StanHeaders have been triggered too.

Great. Thank you as always!!!
