Hi Josiah, Indeed, the right thing to do is to declare the library in the SystemRequirements file. However, other than some specific documented usages which affect how R builds the package (e.g. C++ standards and GNU make), I believe the field is meant more just to inform users of the external dependencies required, so they could install those themselves before attempting to install the package. The R extensions manual has:
https://cran.r-project.org/doc/manuals/R-exts.html#The-DESCRIPTION-file > Dependencies external to the R system should be listed in the > ‘SystemRequirements’ field, possibly amplified in a separate README file. > This includes specifying a non-default C++ standard and the need for GNU make. Also note that, for any external dependency required by the package, you should also check its existence in the package configure script. https://cran.r-project.org/doc/manuals/R-exts.html#Configure-and-cleanup > Use this to detect if any nonstandard libraries are present such that > corresponding code in the package can be disabled at install time rather than > giving error messages when the package is compiled or used. The curl package (and its dependency on libcurl) is the first thing that comes to mind and could be a useful reference. https://github.com/jeroen/curl/blob/master/DESCRIPTION#L21 https://github.com/jeroen/curl/blob/master/configure Best, Kevin On Tue, May 7, 2024 at 6:56 AM Josiah Parry <josiah.pa...@gmail.com> wrote: > > In my Makevars file (linked below) I link to ssl by adding `-lssl` to > `PKG_LIBS`.
