Qiang,

<div class="">Sorry for the late reply (somehow your reply ended up in the Junk folder). Switching RcppArmadillo and RcppEigen in the LinkingTo section (and thus the header order) did not help BUT your mention of NDEBUG lead me to this Githuhb issue: <a href="https://github.com/RcppCore/RcppArmadillo/issues/116" class="">https://github.com/RcppCore/RcppArmadillo/issues/116</a>.
The addition of a similar file in the inst folder (see change log at the bottom of the issue) with #define NDEBUG 1 and then adding the file as an import in RcppExports.cpp did the trick. Unfortunately, running compileAttributes() locally overwrites the manual
changes in RcppExports.cpp but, for now, I guess I will have to live with this. Thanks a lot for your input!</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="">I found a similar problem previously discussed (here: <a href="https://mailfilter.sunet.se/canit/urlproxy.php?_q=aHR0cDovL3JjcHAtZGV2ZWwuci1mb3JnZS5yLXByb2plY3QubmFya2l2ZS5jb20veWMxaDhiZjYvcmNwcGVpZ2VuLXBhY2thZ2Utc2tlbGV0b24tci1jbWQtY2hlY2std2FybmluZw%3D%3D&_s=amFzb24uc2Vydmlzc0BraS5zZQ%3D%3D&_c=f9d02bc5&_r=a2ktc2U%3D" target="_blank" class="">
http://rcpp-devel.r-forge.r-<wbr class="">project.narkive.com/yc1h8bf6/<wbr class="">rcppeigen-package-skeleton-r-<wbr class="">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://mailfilter.sunet.se/canit/urlproxy.php?_q=aHR0cHM6Ly9naXRodWIuY29tL2phc29uc2Vydmlzcy9jaGVjaw%3D%3D&_s=amFzb24uc2Vydmlzc0BraS5zZQ%3D%3D&_c=fd24f0d8&_r=a2ktc2U%3D" target="_blank" class="">
https://github.com/<wbr class="">jasonserviss/check</a>) and automated the build with TravisCI (build report here:
<a href="https://mailfilter.sunet.se/canit/urlproxy.php?_q=aHR0cHM6Ly90cmF2aXMtY2kub3JnL2phc29uc2Vydmlzcy9jaGVjay9idWlsZHMvMzkxNjg1MjU2&_s=amFzb24uc2Vydmlzc0BraS5zZQ%3D%3D&_c=717fbb88&_r=a2ktc2U%3D" target="_blank" class="">

<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>
