Not sure if this is a bug or intended behaviour, but a heads up to all Windows cmdstanr users who suddenly get “CmdStan path has not been set yet.” error, even when they succesfully used cmdstanr previously. Between cmdstanr 0.7.1 and 0.8, the location where a Cmdstan installation is expected by de…

Oh no, that definitely wasn’t intentional. I think it’s a side-effect from a fix for OneDrive path issues. I’m already doing a bugfix release today, so I’ll add a fix for that as well. Thanks for the heads up!!

I didn’t realize cmdstanr was using a different default location than cmdstanpy (we are just in the user folder, not Documents/). It doesn’t look like that is documented, either. I think some windows configs essentially symlink the documents folder into OneDrive, so I would be sure that changing it…

It’s because the default was always in $HOME, which is in Documents on windows

$HOME is not set by the Windows operating system

Ahhh it wasn’t even a cmdstanr or onedrive issue in the end! The cmdstan makefile has an -include for a file in $(HOME) , which breaks if there is a space in the path (at least on Windows): -include $(HOME)/.config/stan/make.local This just needs to be quoted, and then all seems to work: -includ…

Looks like the same include is in the Stan & Math makefiles as well

Are there not other issues actually building? I seem to recall g++ itself complaining on Windows about spaces in paths If that’s all that’s needed, 1) that’s pretty funny and 2) that’s an awesome find!

Seems to fix things for cmdstanr at least! Was legitimately questioning my sanity when calling make in C:/cmdstan failed with errors about the onedrive folder though

Does that include just get ignored when $HOME is unset? (e.g., outside of R?)

CmdStan path has not been set yet, Windows, cmdstanr 0.8
