Since a recent reinstall of my compiler toolchain I encounter a strange error that prevents me from compiling any models with rstan as well as compiling rstan itself. For example install.packages("rstan", repos = c("https://mc-stan.org/r-packages/", getOption("repos"))) (or any attempt to compile…

I have found the problem after you suggested that in may be the compiler flags. In my Makevars I had CXX14FLAGS = -O3 -mtune=native CXX14FLAGS += -arch x86_64 -ftemplate-depth-256 I don’t know where I got the second line from, perhaps an old Stan discourse post about M1 Macs? In any case, commen…

That’s definitely an odd one! Can you try compiling c++ through both R CMD SHLIB and Rcpp? I’m wondering which stage is introducing the error: system('touch foo.cpp') system('R CMD SHLIB foo.cpp') and Rcpp::sourceCpp(code=' #include <Rcpp.h> // [[Rcpp::export]] int fibonacci(const int x) …

Thanks for coming back to me so quickly! Below is my reprex and output of R: > sink("foo.cpp") > cat(' + int fibonacci(const int x) { + + if (x == 0) return(0); + + if (x == 1) return(1); + + return (fibonacci(x - 1)) + fibonacci(x - 2); + + }') > sink() > system('touch foo.cpp'…

The plot thickens! So likely something related to rstan's compiler flags then. Can you try the example model and post the output? That should show what flags stan is using and where: example(stan_model,package="rstan",run.dontrun=T,verbose=T)

Phew, glad it was something simple!

Me too! I am just confused that It did work before with -arch x86_64 on my M1 Mac and only refused to work after some update on the system side. Thank you very much for your help!

I located and deleted the Makevars file but now when I run the following code Rstudio crashes (“fatal error”) example(stan_model, package = "rstan", run.dontrun = TRUE) It seems that I got that line from the following initially: dotR ← file.path(Sys.getenv(“HOME”), “.R”) if (!file.exists(dotR)) …
