Cmdstanr under R4.3 and Rtools 4.3

Interfaces CmdStan

I just updated R and RTools to version 4.3, since these are the forthcoming releases, but now I get an error when installing cmdstanr:

Error: 
Rtools42 was not found but is required to run CmdStan with R version 4.3.0.
Please install Rtools42 and run cmdstanr::check_cmdstan_toolchain().

Is there any setting I have missed, or does cmdstanr indeed not yet work with RTools 4.3?

Can you share the output from:

devtools::session_info("cmdstanr")

This actually seemed like a fairly simple case of updating some utility functions. Can you try this github version and let me know if all gets set up and installed correctly:

EDIT: Removed command to install branch, now in main

Thanks a lot, worked!

Great! The updates have been merged into the main repository as well, so the standard github version of cmdstanr should now be RTools43 compatible

I still get the same error: > cmdstanr::install_cmdstan()
Error:

Doing a fresh install, and I have the same problem with cmdstanr and Rtools43 with R 4.3.1.

Update: following another thread, I tried reinstalling cmdstanr using remotes::install_github(“stan-dev/cmdstanr”)

But receive the same error notifying me that Rtools42 was not found.

One more update: in doing my reinstall, I neglected to install devtools first. So, now when I checked the toolchain with the fix=TRUE option, cmdstanr installed mingw32-make and g++ with Rtools43. Weird. Will see if compilation works!
