Hi,

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: https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started

The model fails:

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

Compilation ERROR, function(s)/method(s) not created! In file included from C:/R/R-3.6.2/library/StanHeaders/include/stan/math/prim/arr/functor/integrate_ode_rk45.hpp:17:0,

EDIT:

system(“g++ -v”) results in 127
