Hello everyone,
<div class=""><br class="">
</div>
<div class="">I am currently in the process of trying to utilise C++ via Rcpp, RcppEigen, and RcppArmadillo in a package for the first time. I am experiencing the following on running devtools::check() with the package:</div>
<div class=""><br class="">

</div>
<div class="">I found a similar problem previously discussed (here: <a href="http://rcpp-devel.r-forge.r-project.narkive.com/yc1h8bf6/rcppeigen-package-skeleton-r-cmd-check-warning" class="">
http://rcpp-devel.r-forge.r-project.narkive.com/yc1h8bf6/rcppeigen-package-skeleton-r-cmd-check-warning</a>) some time ago although, in this case, it seemed to be system specific. Based on the comments, I created a minimal reproducible example (here:
<a href="https://github.com/jasonserviss/check" class="">https://github.com/jasonserviss/check</a>) and automated the build with TravisCI (build report here:
<a href="https://travis-ci.org/jasonserviss/check/builds/391685256" class="">https://travis-ci.org/jasonserviss/check/builds/391685256</a>). </div>
<div class=""><br class="">
</div>
<div class="">I have noticed two things:</div>
<div class=""><br class="">
</div>
<div class="">1) there are 2 functions in the package, function “a" and function “b”, if I remove function “b” I no longer receive the warning. Despite this, there wouldn’t, to my eyes, seem to be anything extremely unusual about function “b”.</div>
<div class=""><br class="">
</div>
<div class="">2) If I remove RcppArmadillo from the LinkingTo section in the DESCRIPTION file I, again, no longer receive the warning. I am aware of the fact that, in the example, there is no need to link to RcppArmadillo although, in the real use case, there
is.</div>
<div class=""><br class="">
</div>
<div class="">Id be very appreciative if anyone here could help me get an understanding for this warning and how it can be resolved!</div>
<div class=""><br class="">

<div class="">Kind Regards,</div>
