**Hello,**

**After trying to fit this model:**  
**xbayes ← brm(y ~ x, mytib)**

**I am getting this error:**

Compiling the C++ model  
Error in compileCode(f, code, language = language, verbose = verbose) :

Error in sink(type = “output”) : invalid connection

**I did this and I got 10:**

fx ← inline::cxxfunction( signature(x = “integer”, y = “numeric” ) , ’  
return ScalarReal( INTEGER(x)[0] \* REAL(y)[0] ) ;  
’ )  
fx( 2L, 5 ) # should be 10

**Here is more information:**

I have Xtools 10 installed.

Try

```
stancode <- 'data {real y_mean;} parameters {real y;} model {y ~ normal(y_mean,1);}'
mod <- stan_model(model_code = stancode, verbose = TRUE)

```

and tell us what is the string involving `error:` (with the colon).

Here are the things I would try if rstan is not working: Make sure you have opened Xcode once via Spotlight to accept its license If that doesn’t work but you have a /Library/Developer/CommandLineTools/Packages/macOS\_SDK\_headers\_for\_macOS\_10.14. pkg, install that so it puts C++ headers back in /usr/include I…

I really appreciate your help, but I feel like you’re speaking Russian to me (I don’t speak Russian). I am a psychologist, not a programmer/developer, and I’m getting more confused. I tried the first option and did not work.

I followed this path:  
/Library/Developer/CommandLineTools/Packages/

and the only thing I found is a folder called usr which only contains another one called share.

I do not know how to rename / delete / empty the ~/.R/Makevars either :(

Hi again,

I updated Mojave, and reinstalled Xcode. I got the latest version (10.2 beta 4). Now the error I’m getting is this:

Compiling the C++ model  
running command ‘’/Library/Frameworks/R.framework/Resources/bin/R’ CMD config CXX14 2\>/dev/null’ had status 1Error in if (nchar(CXX) == 0) { : argument is of length zero

^bangs head against table in frustration^

Make sure you have accepted the license agreement for Xcode by opening it once via Spotlight. Then tell us what

```
pkgbuild::has_build_tools(debug = TRUE)

```

says.
