I wanted to run some models making use of `cmdstanr` but I get error messages the whole time. I checked my cdmstan installation etc and tried to compile the example of the website. This generates the following errors:

```nohighlight

The C++ toolchain required for CmdStan is setup properly!

I’m really not so familiar with all what is going on in the background (like Xcode stuff and so on) but it used to work in the past (before updating to MacOS Monterey I guess.

- Operating System: MacOS Monterey

Can anyone help?

Can you try changing your system to used the Commandline Tools? Open a terminal and run:

```nohighlight
sudo xcode-select -s /Library/Developer/CommandLineTools

```

Then in R, run:

```r
cmdstanr::rebuild_cmdstan()

```

Tried that but I get a lot of errors when running the `rebuild_cmdstan()`

Error (I only copied a part):

Next I’ll need to see the compiler being called and its flags, can you post the output from the following:

```r
system("touch foo.cpp && R CMD SHLIB foo.cpp")

```

If you could also post the output from the very start of the `rebuild_cmdstan()` call which shows the compiler and flags and there as well

It looks like you have `rstan` loaded, can you close and re-open R (making sure that no packages and objects get loaded) and then run:

```r
system("rm foo.o && touch foo.cpp && R CMD SHLIB foo.cpp")

```

To see the flags again?

Hi  
Now I get this:

```nohighlight

That’s fine, just remove the `rm foo.o &&` from the command and run again

Looks like it worked, can you try the `rebuild_cmdstan()` call now?

Errors again… And the annoying thing is that it doesn’t print everything in the Console (the top part is chopped away).

I found the solution in another corner than the stan-related fora. Seems I had a more general problem with compiling. Could not install packages from source neither in R.

Solution was to delete `/usr/local/include` from my system (a folder created when using brew).

It was a local issue, so I’ll close the discussion.  
@andrjohns : THX for trying to help me. Much appreciated!
