Dealing with Catalina IV

Interfaces RStan
2

I am on macOS Catalina 10.15.3
and using R version 3.6.3 (2020-02-29)

I followed the instructions here, installing rtools and then running install.packages(c(“StanHeaders”, “stan”), type = “source”).

However, when I now try to install RStan (by calling install.packages(c(“rstan”), type = “source”)), I get the following error:

make: *** [pointer-tools.o] Error 1
ERROR: compilation failed for package ‘rstan’

Any ideas for how to fix this? Seems like it might be related to this error
