Warning Message

Modeling
1

Hello All,

This is likely a familiar problem. When I estimate a STAN model using the “rstan” package in R (“stan_model”), I get the warning message below:

In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) :
‘C:/rtools40/usr/mingw_/bin/g++’ not found

The estimate proceeds correctly. However, I am interested in addressing the warning message.

Hi Ziad,

That warning is completely safe to ignore. It was a slight misconfiguration on our end that will be fixed in the next release

Many thanks for the confirmation, Andrew. I will ignore it.
