Warning - 'config' variable 'CPP' is deprecated #862

Open hhau opened 4 years ago

hhau commented 4 years ago

Summary:

After encountering #774 and installing this version of rstan I get a 'config' variable 'CPP' is deprecated warning message / error. I think this is happening here. It looks like this was depreciated in R 3.6.2: https://cran.r-project.org/bin/windows/base/old/3.6.2/NEWS.R-3.6.2.html

Everything Stan related still works as it should, but it makes some of my package's tests fail.

Reproducible Steps:

library(rstan)

res <- stan_model(
  model_code = "data {} parameters {real x;} model {x ~ std_normal();}"
)

gives :

 'config' variable 'CPP' is deprecated
clang -mmacosx-version-min=10.13 -E
Warning message:
In system(paste(CPP, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) :
  error in running command

RStan Version:

‘2.21.3’, 27a744a

R Version:

"R version 4.0.3 (2020-10-10)"

Operating System:

OS X 10.15.7

Thanks for reporting this. If that's deprecated we should remove it. I don't really know anything about this so tagging @bgoodri in case he hasn't seen this yet.

As for the failing tests, @hhau do you know why this is causing a failure if Stan ends up running properly despite the warning? Are the tests set up to fail if there are any warnings at all? I thought tests should pass with warnings unless you use something like testthat::expect_silent(). Anyway, I'm just curious. We should definitely fix the problem regardless.

Yes, you are correct and this is what happens (Apologies, my earlier comment was wrong).

Glad the tests aren't failing, but thanks for letting us know about this warning.

@bgoodri Just following up here to say that with the latest 2.21.3 from github I'm also seeing the same warning @hhau reported:

'config' variable 'CPP' is deprecated
clang -mmacosx-version-min=10.13 -E

and then 

Warning messages:
1: In system(paste(CPP, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) :
  error in running command

None of these prevent it from running but it would be good to clean them up for the next release.

It is a relatively new R development. We'll deal with it.

After updating to the latest R version, this now works. But I'll keep the post here, in case someone else with the older R version is experiencing the same error.

I originally got both the "clang -mmacosx-version-min=10.13 -E" warning and the unserialize error, even with the most recent rstan version:

Reproducible example:

set.seed(123)
y <- rbinom(30, size = 1, prob = 0.2016)

# Fitting a simple binomial model using Stan
library(rstan)

model_string <- "
data {
  int n;
  int y[n];
}
parameters {
  real<lower=0, upper=1> theta;
}
model {
  y ~ bernoulli(theta);
}"

stan_samples <- stan(model_code = model_string, data = list(y = y, n = length(y)) )

If just run with one chain, this crashes in RStudio. In R, a prompt appears "selection:" and R crashes regardless of the choice (it's unclear what the choices are so I tried "1" and "2"; not entering anything repeats the prompt).

Can confirm updating to R 4.1 from R 4.0.x and reinstalling RStan on MacOS Big Sur has fixed this problem for me.

If install from CRAN, I don't get this problem. If I clone the latest develop from git and install from the local directory, I get warning and error

> 'config' variable 'CPP' is defunct
Warning message:
In system(paste(CPP, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) :
  error in running command

RStan in CRAN says Published: 2021-12-19, but NEWS tells the latest change is Fri July 24 2020. git repo has develop as the default branch, but there is no tag indicating which version is 2.21.3. I'm confused!
