[Rcpp-devel] _ZSt4cout warning

Hi Joshua,

| I got flagged for the _ZSt4cout warning below on a recent CRAN submission of an
| R package which depends on RcppArmadillo.  
| 
| * checking compiled code ... NOTE
| File
| ?/data/smith/R/packages/incoming/SpatialTools.Rcheck/SpatialTools/libs/
| SpatialTools.so?:
|    Found ?_ZSt4cout?, possibly from ?std::cout? (C++)
| 
| Compiled code should not call functions which might terminate R nor
| write to stdout/stderr instead of to the console.  The detected symbols
| are linked into the code but might come from libraries and not actually
| be called.
| 
| See ?Writing portable packages? in the ?Writing R Extensions? manual.
| 
| The warning isn't new, but I'd never been flagged on it before.  It seems to
| have been discussed here:  http://lists.r-forge.r-project.org/pipermail/
| rcpp-devel/2011-November/003133.html
| 
| I was just wondering if this had been resolved or if work continues to resolve
| it?

Some good news and some bad news:

  Good news:  We have this fixed in RcppArmadillo and are ready to upload,
              Conrad also very kindly made a small change at his end.

  Bad news:   This depends on a small change in Rcpp, and we ourselves are
              currently being held-up at CRAN on 'R CMD check' output that
              used to pass but no longer does (in this case, using .Internal
              and modifying a locked binding which is something Rcpp modules
              needs).

So this should be sorted out "soon" for various values of soon, but we have
been at this for a bit now.  

We will certainly announce new versions here.
