Error in compiling brms model on cluster

Dear All,

I am getting errors in compiling the simplest brms (brms_2.9.0) model on a linux cluster:
R version 3.5.3 (2019-03-11)
Platform: x86_64-pc-linux-gnu (64-bit)
Running under: CentOS Linux 7 (Core)

this is the error I get:
fit1 <- brm(count ~ zAge + zBase * Trt + (1|patient),

  •         data = epilepsy, family = poisson())

Compiling the C++ model

Error in compileCode(f, code, language = language, verbose = verbose) :
Compilation ERROR, function(s)/method(s) not created! In file included from /R/R-3.5.3/library/BH/include/boost/random/detail/integer_log2.hpp:19:0,

from /home/giuseppe.formetta/R/R-3.5.3/library/StanHeaders/include/stan/math.hpp:4,

Finally my Makevars file looks like:

CXX14=g++ ‘-std=c++11’
CXX14FLAGS = -O3 -mtune=native -fPIC -march=native -fno-fast-math

When I type Sys.getenv(“R_MAKEVARS_USER”) this is what I get:
[1] “”

Any help is very welcome

The error message seems truncated, could you try to get the full error output?

Also check the steps at to verify your toolchain is well configured on the cluster.

P.S. Note that you can use backticks (`) and triple backticks for inline code and code blocks respectively to make your posts easier to read :-)

Thanks a lot
problem solved
