[R-pkg-devel] Failure at pretest stage on Debian CRAN server due to system requirements (nlopt)

[julien chiquet]

Hi,

I am trying to submit a package to CRAN that fails during the pretest
process on Debian.

I use the some C++ code that interfaces to the nlopt optimization
library with Rcpp/RcppArmadillo. Thus, my package requires a system
version of nlopt that can be installed via the deb package
libnlopt-dev (I added this to the SystemRequirements field).

I use a configure script and pkg-config to retrieve the (hopefully)
appropriate compiler flags which I then send to src/Makevars
NLOPT_LIBS=`pkg-config --libs ${PKG_CONFIG_NAME}`
NLOPT_FLAG=`pkg-config --cflags ${PKG_CONFIG_NAME}`

This approach works on my system (Ubuntu 18.04, R 3.5.2) and on Travis
(linux and mac OS), but fails on the Debian CRAN server :
https://win-builder.r-project.org/incoming_pretest/PLNmodels_0.7_20190119_161032/Debian/00install.out

I added some verbosity to check that the flags were correctly exported
on CRAN servers, and they seems alright to me: at least, a version of
nlopt is found on the system (see below, NLOPT_LIBS=-lnlopt -lm).
However, the <nlopt.hpp> is not found latter on...

Any help would be greatly appreciated. Thank for taking the time to read this.
