After moving to R 4.0 and the most recent version of STAN, I’m getting a really strange error while trying to compile using
stan_model. The process throws an error with:
Error in cleanup_makevar(old) : argument "RMU" is missing, with no default.
Google and searching these forums didn’t turn up any insights. I’ve reinstalled my toolchain and removed all prior versions of R and RTools, and tried a couple alterations to the Makevars files.
devtools::session_info("rstan") flags an issue with the
RcppParallel package with:
D -- DLL MD5 mismatch, broken installation. Unsure if that is relevant.
Last, here are the key bits of session info:
- version R version 4.0.2 (2020-06-22)
- os Windows 10 x64
- system i386, mingw32
Thanks in advance for any and all help!
I’m also getting this warning, which as I understand can be safely ignored, but I’m including it to be comprehensive.
In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) : ‘C:/rtools40/usr/mingw_/bin/g++’ not found
