Error in STAN/ BRMS functions using R 3.6.2


I had to reinstall the system and after installing brand new R 3.6.2 I am having issues while using STAN/brms on Windows 10.

After following the instructions:

The model fails:

‘compileCode(f, code, language = language, verbose = verbose)’:

I’m having the same issue on Windows 10. I wonder if it is related to this change in R 3.6.2:


  • The default standard for C++ in package installation is C++11 (as it has been on other platforms where available since R 3.6.0: the default toolchain on Windows was defaulting to C++98).


  • Support for specifying C++98 in package installation is deprecated.
  • Support in R CMD config for F77, FCPIFCPLAGS, CPP, CXXCPP and CXX98 and similar is deprecated. (CPP is found from the system make and may well not be set.) Use $CC -E and $CXX -E instead of CPP and CXXCPP.

My C++ toolchain configuration is:

CXX14=$(BINPREF)g++ -O2

Perhaps some of this needs to change?

This is a BH bug. Do

install.packages("BH", type = "win.binary")

This fixed it! Hopefully the next BH release will address the issue.

Thank you, @bgoodri ! It worked on my home PC, gotta try it out @ work. :)

@bgoodri Still getting an error after installing BH, any pointers?

@majormongoose @bgoodri
I ran into the same issue mid model tuning now. Seems ‘BH’ pushed an update today and that must have broken it?

I removed it and installed an old version and that fixed it for me:

install_version(“BH”, version = “1.69.0-1”, repos = “”)

I would do

This one worked wow, thank you so much!

Another weird thing is now that I can fit the 8 schools example is that I got a divergent transition warning. I just ran the line a few times and it went away however.

MCMC is not deterministic (without a fixed seed), so sometimes you get a divergent transition or two and sometimes you don’t. All the more reason to run at least four chains.

I see, weird that isn’t in the quick start guide. Although I am a complete novice so… Thanks so much again!

BH 1.72.0-2 is now on CRAN and has the fix

  • inst/include/boost/numeric/odeint/stepper/: Correct accidental
    renaming in this directory, only rename in …/generation/


Glad this barrier is solved.
