[Rcpp-devel] Package Submission Barred by Pedantic

When you say "unset it", do you mean physically delete the flag from the
file?

I don't see the pedantic flag set in my {R_HOME}/etc/Makeconf or any
Makevars file locally, so I tried passing "-Wno-pedantic", but this renders
warnings later on about non-portable code.

It might be how R was built, ie the flag got "baked in" when R configured
and
compiled. These flags then sit in ${R_HOME}/etc/Makeconf.  If so you'd
have
to edit the file -- we can't alter these options on the fly.

Or it could be in a file of yours, for me it is ~/.R/Makevars where I in
fact
often set -pedantic (and alsod unset it).

The bigger news is that you should not have to worry about it. It is just
a
warning, and it comes from code you did not write but just use -- Boost
headers via the BH package.
