Compiling issue with stan in the R package 'brms'

General
1

I’m looking for help to implement Rtools/stan through the ‘brms’ R package. After following the instructions for installing Rtools, ensuring that the rstan tool chain works, and reinstalling R, R Studio, and rstan, I’m still not able to have the compiler called correctly. All of the checks on the rstan github page work (https://github.com/stan-dev/rstan/wiki/Installing-RStan-on-Windows#toolchain) with proper locations for each item.

I’m using R version 3.4.3 and Rtools34, with g++ v. 4.9.3 called.

When I call the brm() function from ‘brms’, it starts to work (‘Compiling the C++ model’), but I eventually reach the following error:

Error in compileCode(f, code, language = language, verbose = verbose) :
Compilation ERROR, function(s)/method(s) not created! In file included from C:/…/R/win-library/3.3/BH/include/boost/config.hpp:39:0,
from C:/…/R/win-library/3.3/BH/include/boost/math/tools/config.hpp:13

with a number of other files as well. I’ve searched for this error online, and have reinstalled these files to no avail.

Any ideas?

We need to see the whole error message, but at this point I would guess that you need to make sure that your ~/.R/Makevars file does not have -mtune=native -march=native anywhere in it.

3

~/.R/Makevars file contains:

CXXFLAGS = -O3 -Wall $(DEBUGFLAG) -mtune=core2 #set_by_rstan
R_XTRA_CPPFLAGS = -I"$(R_HOME)/include" #set_by_rstan
CXXFLAGS=-O3

4

You may need to remove that -mtune=core2.

I removed that from the Makevars file. Still no change to the error message.
Any other ideas?

posting the full error message

I edited the question with the full error message already. That’s all there is.

8

Am I missing an error message that might be elsewhere?

There should be more to it, yet. Can you paste the output of

stan_model(file.stan, verbose = TRUE)`
