Lots of warnings During Compilation #127

Closed xbasics closed 1 year ago

xbasics commented 1 year ago

Every time I compile RcppEigen I'm getting what seems to be quite a lot warnings like the following. Warnings alone should not be causing problems in calculations done through this package. Yet I wonder if other users are encountering these same warnings when compiling this package and if they have notice/encountered any issues.

Duplicate of #25 filed only two weeks ago (as well as of course many identical earlier questions).

Feel free to reopen if you really think you can add anything substantial here but in short CRAN requires this are the best (local) remedy is flags in ~/.R/Makevars. It is irritating me too but as said: nuttin' we can do here.
