I recently submitted a package to CRAN with "SystemRequirements: C++11".
This raises the following NOTE on R-devel, and I was asked to fix and
resubmit:
* checking C++ specification ... NOTE
Specified C++11: please update to current default of C++17
If I understand correctly, I have two options, neither of which will work:
1. Remove "SystemRequirements: C++11" entirely. The problem with this is
that on systems with older versions of R (3.6 and below, I believe), it may
try to compile the package with an older C++ standard, which will fail.
2. Update it to "SystemRequirements: C++17". The problem here is that on
systems that don't have a C++17 compiler, the package won't build -- even
though the package only actually requires a C++11 compiler.
How should I deal with this?
