C++ toolchain problem (Mac OS X Mojave)

RStan (and brms) suddenly stopped working for me while I was trying to solve some bookdown package update problems.

I followed the instructions here:

For the check to see whether I have build tools, I get:

pkgbuild::has_build_tools(debug = TRUE)
[1] TRUE

Then I tried to run 8schools.

library(rstan)
options(mc.cores = parallel::detectCores())
rstan_options(auto_write = TRUE)

schools_dat <- list(J = 8, 
                    y = c(28,  8, -3,  7, -1,  1, 18, 12),
                    sigma = c(15, 10, 16, 11,  9, 11, 10, 18))

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

Output:

library(rstan)
options(mc.cores = parallel::detectCores())
rstan_options(auto_write = TRUE)
schools_dat <- list(J = 8,

  •                 y = c(28,  8, -3,  7, -1,  1, 18, 12),
    
  •                 sigma = c(15, 10, 16, 11,  9, 11, 10, 18))
    

fit <- stan(file = ‘schools.stan’, data = schools_dat)

with R 4.0 you should not do all that isysroot business and you should just use the stock compiler from Apple. Please lookup the R 4.0 thread on the forum.

Thanks. I followed this advice from Stephen Martin (is this what you meant?):

"You do not need the macos-rtools anymore, for R 4.0.
I encountered this error in my OSX testing as well.

Rename (or delete) ~/.Renviron and ~/.R/Makevars

That will ‘undo’ the configuration of macos-rtools.
Then test rstan in a new R session."

Now I get:

another R 4.0 matter; also solved in one of the threads here (sorry, don’t know by heart which one)

Thanks, I found the discussion here:

I realized from the above that the problem is parallelization in RStudio. I haven’t solved that yet, but I can live with a slow serial compilation for now, at least everything works in principle. Phew, I spent the whole day on this…

I think it was this one:

I cannot make brms work any more however. I installed brms after getting rstan working (at least through the terminal, not RStudio).

I ran a simple model that until yesterday was working, and I get:

> df_noreading_data <- read_csv("./data/button_press.csv")
Parsed with column specification:
cols(
  rt = col_double(),
  trialn = col_double()

It looks like I do need the C++ libraries etc. that were not needed for rstan?

The *conda installations are finicky with Stan and may have their own configuration files. Basically with R 4.0, you want to only use the compiler / libraries / headers / etc. that come with Xcode. Maybe someone else who has RStan installed via miniconda knows how to do that?

BTW, I didn’t install RStan using miniconda.

I am not sure why, but it is looking for non-existent files under Users/shravanvasishth/miniconda3/.
