Guide: Diagnosing a complete lack of output on Windows

Interfaces CmdStan

In my case, I only have

where.exe tbb.dll
C:\Windows\System32\tbb.dll

and I do have Visual studio installed and use an Intel CPU but this does seem to relate the the message that I get at the end of building:


NOTE: Please add C:/Users/Polly/Documents/.cmdstan/cmdstan-2.33.1/stan/lib/stan_math/lib/tbb to your PATH variable.

You may call

mingw32-make install-tbb

to automatically update your user configuration.

Is the problem you describe here also the reason why I
a) get the following message when I try to run a brms model via cmdstnr:

Before it says they are not finished, it always gives me the “In the file included message” if I am not working than this message is also red in the building process but I don’t if they are related.

Error in cmdstanr::read_cmdstan_csv(out$output_files(), variables = "",  :

In addition: Warning message:

and b) sometimes even rstan seems to fail saying it can access some .txt file.

When using brms how do I do Fix 1? Where is my model .exe in this case?
