Is anyone else getting strange problems on winbuilder with rstan model compiles? All checks on other windows machines I can find are ok, but on winbuilder I get errors everywhere as if it is using either an older version of the model, data, or just can’t find the data objects when called by rstan. Like this:
Error in new_CppObject_xp(fields$.module, fields$.pointer, ...) :
Exception: variable does not exist; processing stage=data initialization; variable name=tipredsdata; base type=matrix_d (in 'model_ctsm' at line 308)
@Charles_Driver Which version of RStan / stanc3? In general, this happens when one or more data objects aren’t parsed correctly from the C++ code. For instance, stanc3 has added _data suffix to internal names, which has been addressed in the experimental branch of RStan
Can you share a reproducible example? I’d also test it using:
remove.packages(c("StanHeaders", "rstan"))
remotes::install_github("stan-dev/rstan/StanHeaders@experimental", upgrade = "always", force = TRUE)
remotes::install_github("stan-dev/rstan/rstan/rstan@experimental", upgrade = "always", force = TRUE)
Well that’s the fun part, only the owners of win-builder upload page (i.e CRAN) can reproduce it, so I was wondering if other package devs experience similar. No point playing with github stuff, CRAN only.
