[R-pkg-devel] RcppArmadillo-based package works in every tested OS except Debian

[Julia A. Pilowsky]

Hello Dirk,


Thank you for the advice. Currently I get a bug whenever I try to use R Builder on my computer, no matter which browser I launch it from, but I will try the Rocker images, as I have worked with Docker before and have some familiarity.


Gratefully,

Julia

Hi Julia,

The error is for the unit test the package has for a RcppArmadillo-based function � all the other unit tests are for R or Rcpp functions.

1) You get easy access to Debian systems via RHub, either using the web
   interface at https://builder.r-hub.io or via the CRAN package rhub.
   A highly recommended service.

2) Another possibility is Docker. It is pretty easy to set up, and I often
   use Docker instances to test things I do not want more permanently on my
   system(s). Also, our Rocker images happen to already use Debian and give
   you R. Maybe start with our recent intro paper to learn more:
   https://journal.r-project.org/archive/2017/RJ-2017-065/index.html

3) As Rcpp maintainer, I happen to run a lot of reverse dependency checks for
   Rcpp, RcppArmadillo, ... and yes, colorednoise also failed for me on the
   last three Rcpp reverse depends checks. I log these in a GitHub repo at
   https://github.com/RcppCore/rcpp-logs -- that won't give you details
   but it simply re-affirms the CRAN failures.

Hth, Dirk
