Hi, I’m trying to fit a brms model that previously worked fine, and get the warning “Compiling Stan program… The NEXT version of Stan will not be able to pre-process your Stan program. Please open an issue at Issues · stan-dev/stanc3 · GitHub if you can share or at least describe your Stan pr…

Today I updated R to v.4.0.2, udated all packages, too. Now I’m getting almost identical errors as Canaan_Breiss whether I run the models directly in rstan as Stan programs or through brms. I get the following message when running one of Stan’s stan_demo() models: The NEXT version of Stan will no…

This might help? [image] Error compiling/running model in Rstan in Mac OSX Catalina RStan I believe those messages will go away if you temporarily do remotes::install_github("stan-dev/rstan", ref = "develop", subdir = "rstan/rstan")

Tried this, got errors: Downloading GitHub repo stan-dev/rstan@develop stan-dev-rstan-a9b5554/StanHeaders/inst/include/libsundials: Can’t create ‘\\?\C:\Users\canaa\AppData\Local\Temp\RtmpqQj6gu\remotes6d30164d62a5\stan-dev-rstan-a9b5554\StanHeaders\inst\include\libsundials’ stan-dev-rstan-a9b555…

Hi there, Today I installed the latest versions of R, Rstudio, and Rtools on a Windows 10 x64 machine, and I downloaded the latest version of brms and rstan. I tried to run several models with the brm() function but unfortunately I have not been able to obtain any result. For instance: > set.seed…

I was having this same exact problem until I rolled Stan back to version 2.19.3, as suggested by Dr. Bürkner on another thread: Potential Problems with rstan and /or brms packages in R 4.0.2

Hi all, I am getting a similar error as the OP with a brms::brm model: Compiling Stan program... Error in compileCode(f, code, language = language, verbose = verbose) : Compilation ERROR, function(s)/method(s) not created! C:/Program Files/R/R-4.0.4/library/rstan/lib/x64/libStanServices.a(stan_f…

What output do you get from the RStan example model: example(stan_model,package="rstan",run.dontrun=T)

The output the first time I ran it was much larger than the space in the console, but the second time was much shorter and manageable… not sure why. The output is attached. stan_model.txt (8.8 KB)

There aren’t any errors in that output, it looks like everything ran and sampled fine?
