[Rd] rhub vs. CRAN fedora-*-devel, using armadillo & slapack

[RICHET Yann]

Dear R-devel people,

We are working to submit a package which is mainly a binding over a C++ lib (https://github.com/libKriging) using armadillo.
It is _not_ a standard RcppArmadillo package, because we also had to provide a python binding... so there is a huge layer of cmake & scripting to make it work with a standard armadillo (but using same version that RcppArmadillo).
It seems now working with almost all CRAN targets, but a problem remains with fedora (clang & gcc) devel.

Our issue is that the rhub docker is not well sync with the CRAN fedora-clang-devel config:
- failing on CRAN (without clear reason): https://www.r-project.org/nosvn/R.check/r-devel-linux-x86_64-fedora-clang/rlibkriging-00check.html
- passing on rhub: https://builder.r-hub.io/status/rlibkriging_0.7-3.tar.gz-20f7dc7562726497af7c678ab41f4dea

So we cannot investigate and fix the problem.

Note that we did quite strange things with the fedora platforms: include explicitely slapack to provide simple precision for our (vanilla) armadillo... 

Do you have any idea, or even known problem in mind, that could be related to this ?

Best regards,
