Can someone with a Mac and a lot of experience upgrade their operating system to Catalina (and Xcode) and tell us if there are any new problems (and solutions) with running Stan beyond what we accumulated for Mojave [image] Dealing with Mojave RStan For the first time, get…

In principle, everyone could just use Xcode but you lose out on the ability to use OpenMP and all the R packages compiled on C…

From reading @nicokist ’s output, he’s using the homebrew compiler… [image] nicokist: /usr/local/Cellar/r/3.6.1_1/lib/R/bin/R CMD SHLIB -o ‘sourceCpp_3.so’ --preclean ‘file60348a82cd.cpp’ So, moving totally away from R’s official binary works… Maybe this should be escalated over to Simon (mac…

You may have to reinstall it from source at the moment with install.packages("rstan", type = "source")

Does this mean we will have another break when R3.7 moves to clang 8?
