I’ve got another
cmdstanr question – although I think this might apply more generally to CmdStan as well.
I’m on Windows 10 and recently installed R 4.0 and the new Rtools 4.0 and uninstalled Rtools 3.5 prior to that. When I wanted to update CmdStan via
cmdstanr::install_cmdstan(overwrite = TRUE) it said that it could not find
mingw32-make. I couldn’t find anything like that in Rtools 4.0, so I installed Rtools 3.5 again and just added its
\mingw_64\bin\ to my PATH. Now everything works, but it’s a bit weird to have Rtools 4.0 and 3.5 installed simultaneously.
There is probably something I’m missing about using CmdStan/cmdstanr with Rtools 4.0?
