Solaris no longer really matters. Does that mean that CRAN will accept a package which gives errors on Solaris?
You could add C++11 conditionally, ie only on Linux/macOS/Windows Yes, but I always need C++11 for this package. I just wanted to make a small reproducible example. The bigger reproducible example is the package at https://github.com/bnosac/udpipe If I add the Rcpp.h header to file https://github.com/bnosac/udpipe/blob/master/src/udpipe.cpp, I'm getting issues similar to this udpipe.cpp:23406:30: error: macro "Free" passed 2 arguments, but takes just 1 alloc->Free(alloc, p->probs); ​ Also [[Rcpp::plugins(cpp11)]] should not be needed in a package. Thank you for the remark. The udpipe package currently uses CXX_STD=CXX11 in Makevars and specifies SystemRequirements: C++11 in DESCRIPTION. Example was just put there to show a minimal example of the error, coming from when Rcpp compiles the attributes. If you could provide a pointer where I should look for a solution, this would be great otherwise the package which is now on CRAN will be rejected any time soon I think. best, Jan Jan Wijffels Statistician www.bnosac.be | +32 486 611708 On 6 September 2017 at 18:49, Dirk Eddelbuettel <e...@debian.org> wrote: > > Hi Jan, > > On 6 September 2017 at 15:03, Jan Wijffels wrote: > | I'm trying to fix the installation issue I have with the package udpipe: > | https://github.com/bnosac/udpipe but I'm getting issues on Solaris > giving > | messages like this: > > Solaris no longer really matters. > > | If I do not add ​SystemRequirements: C++11 and remove the Makevars file, > | this works fine on Solaris. > > You could add C++11 conditionally, ie only on Linux/macOS/Windows.
