Toolchain not working in Win10

General
1

Hi,

I’m trying to install rstan in R(3.5.3)/Rstudio (1.1.463 )/Windows 10. I installed Rtools35 according to instructions.

When I run

pkgbuild::has_build_tools(debug = TRUE)

it returns

TRUE

like it should.

My C:\\Users\user\documents\.R\makevars.win file contains:

CXX14FLAGS=-O3 -march=native -mtune=native
CXX11FLAGS=-O3 -march=native -mtune=native

However when I try to compile a .stan file it throws an error like this

fit <- stan(file = '8schools.stan', data = schools_dat)

Error in compileCode(f, code, language = language, verbose = verbose) :

Could someone help me out please?

Thanks,

Try it like

fit <- stan(file = '8schools.stan', data = schools_dat, verbose = TRUE)

and then tell us the part of the error message that has the string error: in it.

Thanks for looking into it!

Somehow I managed to make it work by installing rstan and its dependencies in the System Library (Program Files/R/R-3.5.3/library) rather than in the User Library (C:\Users\user-name\Documents\R\win-library\3.5).

My knowledge is not sufficient to explain why this works or why installation in the User Library fails.

It generally should be possible to get it work either way, but it isn’t worth the time to figure out if you have got it working one way now.
