I’m getting this insane error. Environment details: I’m running RStudio Server on Ubuntu: Operating System: Ubuntu 16.04.6 LTS Kernel: Linux 4.4.0-157-generic Architecture: x86-64 Here is the R version stuff: platform x86_64-pc-linux-gnu arch x86_64 …

By golly, reinstalling Rcpp worked! Thanks, Ben!

gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.11)

That compiler isn’t one that we have much experience with, but it is supposed to work. My guess is that Rcpp was installed with a different compiler or settings, so I would try reinstalling Rcpp with what you have in Makevars.

That’s a good suggestion. I’ll try it and report back.

I encounter the same problem and I already removed and reinstalled the Rcpp package. However I did not specify anything according to what is written in the Makevar file. I got the following options on what I read before to make it work with Rtools 4: CXX14=$(BINPREF)g++ -O2 -march=native -mtune=na…

Yes I did. Already followed them twice (install-uninstall-reinstall) and it didn’t solve the problem.

Does the example model compile for you? example(stan_model,run.dontrun = TRUE,verbose=TRUE) If not, can you post the outputs from: Sys.which("make") Sys.getenv("BINPREF") Sys.getenv("PATH") readLines("~/.R/Makevars.win") Just to check for any common sources of configuration issues

I already tried the example yesterday because I read it here ( Error: cannot allocate vector of size 17348.7 Gb - #10 by bgoodri ) but RStudio always freezes and doesn’t react anymore after around 2 minutes. Those are the outputs: Sys.which("make") make "C:\\rtools40\\usr\\bin\\make.exe" Sys.get…

The empty BINPREF actually isn’t an issue, since RTools4 will be automatically taking care of it. It’s usually an issue when it’s not empty, and it’s set to the old rtools directories. There are two things that I would try here, first thing is to try removing the CXX14=$(BINPREF)g++ -O2 -march=nat…

Thanks for the explanation how to remove the path variable. I followed your instruction and after opening a new session I can confirm that it has been removed. I could run the line example(stan_model,run.dontrun = TRUE,verbose=TRUE) now and it does some sampling. However at the end there is a warni…

Have you tried the instructions over in this thread: R 4.0, rstan, and you? They should help
