Hi,

I think my error is from the “classics” and it seems that re-installing rstan could be a solution. However, my company is vetting **every** single package that I need to install. Then they through the installed folder in my library and this is how it works.

My question is if I can make the current rstan instalation to work.

The error I’m getting by running the following,

`R > example(stan_model, package = "rstan", run.dontrun = TRUE)` is

`Compilation ERROR, function(s)/method(s) not created! Error in compileCode(f, code, language = language, verbose = verbose) : C:\rtools42\x86_64-w64-mingw32.static.posix\bin/ld.exe: file45cc4bb579e5.o:file45cc4bb579e5.cpp:(.text$_ZN3tbb8internal26task_scheduler_observer_v3D0Ev[_ZN3tbb8internal26task_scheduler_observer_v3D0Ev]+0x1d): undefined reference to `tbb::internal::task_scheduler_observer_v3::observe(bool)'C:\rtools42\x86_64-w64-mingw32.static.posix\bin/ld.exe: file45cc4bb579e5.o:file45cc4bb579e5.cpp:(.text$_ZN3tbb10interface623task_scheduler_observerD1Ev[_ZN3tbb10interface623task_scheduler_observerD1Ev]+0x1d): undefined reference to `tbb::internal::task_scheduler_observer_v3::observe(bool)'C:\rtools42\x86_64-w64-mingw32.static.posix\bin/ld.exe: file45cc4bb579e5.o:file45cc4bb579e5.cpp:(.text$_ZN3tbb10interface623task_scheduler_observerD1Ev[_ZN3tbb10interface623task_scheduler_observerD1Ev]+0x3a): undefined reference to `tbb::internal::task_scheduler_observer_v3::observe(bool)'C:\rtools42\x86_64-w64-mingw32.static.posix\bin/ld.exe: file45cc4bb579e5.o:file45cc4bb579e5.cpp:(.text$_ZN3tbb10interface `

The makevars is

Oh I see now 😬  
So should it be the 2.26 or the latest version can do the job too?

If you want to use R4.2 you’ll have to use rstan 2.26
