Good morning,
I am trying to release an `R` package to CRAN that contains some compiled C++
code and Stan models. Since adding a new Stan file to the package, I now get
the following issue whenever I run `devtools::check_rhub()` or
`devtools::check_win_devel()`:
* checking whether package 'EcoEnsemble' can be installed ... WARNING
Found the following significant warnings:
WARNING: The tools required to build C++ code for R were not found.
This warning does *not* appear when I install the package locally and did not
appear in the `r_hub`/`win_devel` checks in a previous version of the package
that did not include this additional Stan file. There is nothing unusual about
this Stan model that would lead it to cause issues like this.
Searching for this error suggests that this is an issue with the installation
of RTools, but since this is not created in the local installation I am very
confused. What could be the culprit here / how would I go about debugging this
issue?
Many thanks,
James Martindale
