Rstantools rstan_package_skeleton() failing with "Error in getDLLRegisteredRoutines.DLLInfo"

syclik · December 4, 2018, 7:57pm

I’m trying to follow the vignette on creating a package that depends on RStan: http://mc-stan.org/rstantools/articles/minimal-rstan-package.html

I’m able to install rstantools, but there’s an error in running rstan_package_skeleton(). I don’t know how close it is to being a well-formed package. Some help?

Here’s what happens when I run it:

> rstan_package_skeleton(path="rpkg")

I’ve also verified that this happens on another Mac.

Is there a known work-around? Should I file a bug report? Is there more information I can provide?

Does it work if you specify the stan_files argument?

syclik · December 4, 2018, 8:28pm

No, it does not. Stops in exactly the same place.

More detail: I created a simple, valid model called intro.stan in the working directory. Then I called this:

rstan_package_skeleton("rpkg", stan_files="intro.stan")

syclik · December 5, 2018, 4:32pm

Some more detail… I dug into to the source and I’m finding that this message comes from this line:

> roxygen2::roxygenise(package.dir = DIR, clean = TRUE)
Writing NAMESPACE
Loading rpkg
Error in getDLLRegisteredRoutines.DLLInfo(dll, addNames = FALSE) : 
  must specify DLL via a “DLLInfo” object. See getLoadedDLLs()

I was able to run that outside of the rstan_package_skeleton() code and see it fail. Any suggestions?

bgoodri · December 5, 2018, 4:58pm

Yeah, roxygen2 changed in ways that broke a lot of people’s stuff. I would just try installing rstantools from GitHub

devtools::install_github("stan-dev/rstantools", ref = "dd1009c")

because we call roxygen2 less.

syclik · December 11, 2018, 3:18am

Thanks, @bgoodri. I don’t know exactly what steps I took to fix it, but somehow I got it working.

Gregory · February 11, 2019, 3:58pm

I’m running into the same problem as @syclik. Not when I run rstan_package_skeleton(), but when I run roxygen2::roxygenise(clean=TRUE) as on https://cran.r-project.org/web/packages/rstantools/vignettes/minimal-rstan-package.html

> roxygen2::roxygenise(clean=TRUE)
Updating roxygen version in /Users/name/GitHub/rpkg/DESCRIPTION
Writing NAMESPACE
Loading rpkg
Error in getDLLRegisteredRoutines.DLLInfo(dll, addNames = FALSE) : 
  must specify DLL via a “DLLInfo” object. See getLoadedDLLs()

The instructions at https://cran.r-project.org/web/packages/rstantools/vignettes/minimal-rstan-package.html thus no longer work. I understand this likely has to do with the roxygen2 updates, but I’m a bit at a loss right now how to get the package started without the skeleton, primarily because I don’t know how to create pre-compiled .stan programs.

bgoodri · February 11, 2019, 4:20pm

Have you tried the GitHub version?

remotes::install_github("stan-dev/rstantools", ref = "c3c59fb")

?

Gregory · February 11, 2019, 4:25pm

I had tried it with the ref = “dd1009c” that was posted above, and just now with the ref = “c3c59fb” that you just posted. Neither worked though. I just got the following error:

Updating roxygen version in /Users/name/GitHub/rstanlm/DESCRIPTION
Writing NAMESPACE
Loading rstanlm
Error in getDLLRegisteredRoutines.DLLInfo(dll, addNames = FALSE) : 
  must specify DLL via a “DLLInfo” object. See getLoadedDLLs()```

bgoodri · February 11, 2019, 4:27pm

Did you call rstan_package.skeleton again? It should avoid calling roxygen2 functions completely.

Gregory · February 11, 2019, 4:30pm

The call to rstan_package_skeleton() works without a problem. It’s later in the tutorial when I’m asked to call roxygen2::roxygenise(clean=TRUE) under “Documentation”—about 3/4 of the way down the vignette. If I skip instead to the next step, devtools::install(local=FALSE), it doesn’t appear to compile the .stan file I added (not sure if that’s linked to the roxygen2 step).

bgoodri · February 11, 2019, 4:34pm

Is it on GitHub?

Gregory · February 11, 2019, 4:42pm

Is my working through the vignette on GitHub? I’ve only done the following (where I get the error at the last step):

setwd("~/Github")

rstan_package_skeleton("rstanlm")

setwd("~/Github/rstanlm")

# Place lm.stan in rstanlm/src/stan_files/

# Place lm_stan.R in rstanlm/R/

roxygen2::roxygenise(clean=TRUE)

bgoodri · February 11, 2019, 5:07pm

No, I mean is your package on GitHub?

Gregory · February 11, 2019, 5:43pm

Oh, sure, I just posted it here: https://bit.ly/2GoUtke

bgoodri · February 11, 2019, 6:27pm

This seems to be missing some of the files under the src/ directory.

Try it with

rstan_create_package("rstanlm", stan_files="lm.stan")

Gregory · February 11, 2019, 11:47pm

Just tried this and I still ran into the same error unfortunately. The version where I use stan_files = "lm.stan" is up on Github as well at: https://bit.ly/2I6uLCF

Gregory · February 14, 2019, 5:47pm

Going to answer my own question here, and it has to do with roxygen2 from what I can tell. But one needs to first call pkgbuild::compile_dll() before calling roxygen2::roxygenise(clean=TRUE).

The issue is documented here: https://github.com/klutometis/roxygen/issues/822#issuecomment-441425591

ebuhle · April 2, 2019, 4:38am

I’m getting the same error, at the same point in the rstan_package_skeleton tutorial (following the steps, but using my own package name and files), and pkgbuild::compile_dll() does not work.

I’m using the ref = “c3c59fb" version of rstantools. It successfully created the package skeleton, and I moved two Stan files into src/stan_files (FWIW, it didn’t create this directory automatically, so I added it manually). I put one R function, with roxygen header formatted exactly as in the tutorial, into the R directory. roxygen2::roxygenise(clean=TRUE) fails as described above, but pkgbuild::compile_dll() gives the error:

Re-compiling CJStan 
-  installing *source* package 'CJStan' ...
   ** libs
   no DLL was created
   ERROR: compilation failed for package 'CJStan'
-  removing 'C:/Users/myname/AppData/Local/Temp/Rtmp6TZULL/devtools_install_34ec416f4026/CJStan'
   In R CMD INSTALL
 Error in (function (command = NULL, args = character(), error_on_status = TRUE,  : 
  System command error

Any ideas?

bgoodri · April 2, 2019, 5:08am

Is there a repository for it somewhere? It is probably easier for me to just make a PR that fixes it.
