<div dir="ltr">Dear Rcpp gurus,<div><br></div><div>Today a CRAN maintainer informed us of the failure of a few Rcpp-related packages to build under the new version of the Mac operating system, OS X 10.9 aka Mavericks. </div>
<div>I do have access to a Mac, but I'm reluctant (in fact, unable) to update to Mavericks, therefore I'm in the dark when it comes to fixing /testing for the errors reported in the log file. On a positive note, it appears at first sight that most of the errors are relatively benign, and similar-looking issues are reported for all the packages involved. That gives me hope that once the underlying issue is well identified, most packages can be fixed with minimal changes.</div>
<div><br></div><div>Here's the info we were given from CRAN,</div><div><br></div><div>"OS X 10.9 (aka Mavericks) has a new C++ compiler, clang++ with libcxx headers/runtime. Your package fails to compile with that compiler: see the appropriate log at <a href="http://www.stats.ox.ac.uk/pub/bdr/Mavericks/" target="_blank">http://www.stats.ox.ac.uk/pub/<u></u>bdr/Mavericks/</a> ."<br>
</div><div><br></div><div>My two packages are cda and planar. The error seems to occur in the Modules definition, e.g. from this line in my code</div><div><br></div><div><a href="https://github.com/baptiste/planar/blob/master/src/multilayer.cpp#L231">https://github.com/baptiste/planar/blob/master/src/multilayer.cpp#L231</a></div>
<div><br></div><div>where "function" is judged ambiguous, as far as I understand. This "function" is presumably something from <span style="color:rgb(0,0,0);white-space:pre-wrap">Rcpp/include/Rcpp/module/Module_generated_function.h but I am not familiar with that code.</span></div>
<div><br></div><div>Any ideas, hints?</div><div><br></div><div>Best regards,</div><div><br></div><div>baptiste<br><br></div></div>
