Dear Rcpp gurus, 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. 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.
Here's the info we were given from CRAN, "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 http://www.stats.ox.ac.uk/pub/**bdr/Mavericks/<http://www.stats.ox.ac.uk/pub/bdr/Mavericks/> ." My two packages are cda and planar. The error seems to occur in the Modules definition, e.g. from this line in my code https://github.com/baptiste/planar/blob/master/src/multilayer.cpp#L231 where "function" is judged ambiguous, as far as I understand. This "function" is presumably something from Rcpp/include/Rcpp/module/Module_generated_function.h but I am not familiar with that code. Any ideas, hints? Best regards, baptiste
